I am using Enhancedgrid with an ItemFileWriteStore to fetch a list of items, each one having a name, a description and a date formatted like date('Y-m-d H:i:s').
I want to be able to filter client-side (server request is not an option) on a date range and hide all elements that don't belongs to the selected range.
I already have a filter on the name, and the way I am filtering it's the following code myGrid.filter({"colname": "the text searched"});
Is it possible (I haven't found any example on the internet) to filter between a date range with the same .filter() method ?
I have, so far, tried some of the followings, without success:
// none of this works
myGrid.filter({'dateCol': {largerThanOrEqualTo: '2015-01-01'}})
myGrid.filter({'dateCol': '>=2015-01-01'})
myGrid.filter({'dateCol': ['2015-01-01', '2016-01-01']})

I have a page where I need to display projects from one table according to there status - I need To Do, In Progress, Done like on kanban board. I tried to filter each panel according to status but I guess because I filter the same datasource I end up with the same data in all three panels. Any advice? Thanks!
At least two options come to mind:
Use one datasource, but 3 tables, for each table, bind the Table Row's visible property to the item's status like: #datasource.item.status === "Done", etc. And then for the other two tables do the same but with a different status value, this will basically just hide the rows that don't match your desired status.
Use 3 datasources, and either have a query that loads a specific status, or let the user filter within that status using query filters (#datasource.query.filters.type._equals = "Done"). This way each table is its own datasource and set of records that does not overlap.
I am using SQL Server. I have 2 columns Passed students and Failed Students in my database.
How to write a query which displays both these columns along with a third column which is Total Students which displays the sum of the entries in the row?
EDIT
It is not allowing me to ask another question.So,posting it here:
I have a hyperlink field in my gridview as below:
[Please refer comment for the code.For some reason it doesn't get posted here.]
Its basically a runId.When I click on this hyperlink I am redirected to a page called RunAnalysis.I want to access the value of the runId which was clicked in this page.
I was thinking of using query string but there is no event as far as I know that is fired on click of the hyperlink.
My question is how do I access the runId value in this page ? Can someone tell me if some event is fired so that I can send a query string.
Thanks.
You haven't given a lot of background information so I am assuming many things in my response.
Here is a simple aggregated result set:
SELECT SUM(Passed) AS [Passed],SUM(Failed) AS [Failed],COUNT(*) AS [TotalStudents]
FROM dbo.Students
Now if there is some grouping you want to do then you would add a GROUP BY clause like so...
I'm creating a new column because I don't know your schema:
SELECT GradeLevel, SUM(Passed) AS [Passed],SUM(Failed) AS [Failed],COUNT(*) AS [TotalStudents]
FROM dbo.Students
GROUP BY GradeLevel
ORDER BY GradeLevel
I am trying to create a report putting a field called contact which has the name of a person. This name is linked directly to another table where I keep all the contacts.
For some strange reason, when I include this name (which in query view displays as the name of the contact), instead of the name appearing, the unique ID number is shown on my report.
As mentioned in the article cited in the above comment, you can use a Combo Box control on your report to do the lookup for you. To see how this can be done, create a new report based on the table containing the lookup field, then drag and drop that field onto the report. That will create a Combo Box control with properties that look something like this:
Row Source: SELECT [Clients].[ID], [Clients].[LastName] FROM Clients;
Bound Column: 1
Column Count: 2
Column Widths: 0";1"
You could use a similar Combo Box control on your actual report to display the client's name rather than their numeric ID value.
Another alternative would be to change the Control Source of the report's Text Box control to have it do a DLookUp() on the table. If the lookup field is named [client] then changing the Control Source of the Text Box to something like
=DLookUp("LastName","Clients","ID=" & [client])
would also work.
I wanted to add to the great answer by Gord:
When using a "web" database (started in Access 2007 I think), you cannot change a report's fields to ComboBox style, nor can you use DLookUp(). (web databases lack a ton of features)
The workaround for this, if you want to create a Web-Report that uses lookup fields, is to create a Web-Query first based on your Web-Table (all the Web-* stuff has a www planet icon over the logo, if you create a new Web-DB in Access 2007+ you'll see what I mean)
So, instead of Table -> Report, you'll have to do W-Table -> W-Query -> W-Report.
Then, the only thing you need to customize to get the data right is the W-Query. Start by trying to reproduce the look in the query to match what you want users to see in the report. Note that here in the query, lookups will work fine (instead of the unique ID's, you get field names like you want). However, this will not carry over to the report. To do that, you gotta get the actual text field name you want into the query:
You should already have one table in your query; start by adding the table that your first lookup field points to. For example, the table I want to print is called Stock_Boards, and it has a lookup field called PCBID_lookup that points to the table Stock_PCBs.
Since you're using lookup fields, there should already be a relationship line between the two tables when you add the second one. If there isn't, something has gone horribly wrong.
Now, see how that line connects two fields on the two different tables? For example, I've got my PCBID_lookup field on my Stock_Boards table, which connects to the ID field on my Stock_PCBs table. If I created a report from this now, PCBID_lookup would be a number, a number that correlates to the ID of a record on Stock_PCBs.
To fix it, I will add the name field I want to show up on the report. In my example, that happens to be a Part Number, rather than the ID. I add the PartNumber field from my Stock_PCBs table to the query, and remove the PCBID_lookup field of the Stock_Boards table from my query.
Since PartNumber is what I want to show up on my report, it effectively replaces the original field (PCBID_lookup)
Repeat for all lookup fields you want in your report.
I had 1 more: I removed the Status field of the Stock_Boards table (which was an ID/Lookup) and added the 'Status' field from the Status table (which was the actual text name)
When finished, your query should look exactly how you want the data to appear, without any special tricks or asking Access to do something unnatural. Save your query, and create a web-report from it. Done!
I have an xPage which I have built with 3 combo boxes and 1 view control. I would like to use the 'Filter by column value' option within the view control to provide the options to filter the values, allowing the user to display any combination of the combo boxes. e.g. Only comboBox1, or comboBox1 and comboBox2, or comboBox3 only, or comboBox1 and comboBox2 and comboBox3.
I used the example in the 'xPages Demonstration Application' (http://www-10.lotus.com/ldd/ddwiki.nsf/dx/xpagesdemoapp.htm or http://xpagesblog.com/XPagesHome.nsf/Entry.xsp?documentId=AAC8E26599256FDC852578CB0066CC13) to do the multi-column filtering using a vector of non-categorized columns.
So, I have come across what appears to be a fairly major issue whereby the data needs to be sorted by date. Date is not one of the filters, but it needs to be the first column in order for the data to be sorted correctly. So my first column is a string, YYYYMMDD, to ensure the data is sorted correctly. I tried to use the sort option within the view control and that does not appear to work with the column filtering implemented in this manner.
So, as Date one of the criteria I am filtering by, I have passed that as an empty string - using the thought process that an empty string will select all (as in the url examples above).
The code I have used to do the filtering is:
var vtr:java.util.Vector = new java.util.Vector();
var t1 = sessionScope.Email;
var t2 = sessionScope.Own;
var t3 = sessionScope.Module;
vtr.addElement("");
#If(sessionScope.Own=="My calls",vtr.addElement(t1),vtr.addElement(""));
#If(sessionScope.Own=="My calls",vtr.addElement(""),vtr.addElement(t2));
#If(sessionScope.Status=="Open",vtr.addElement("Open"),vtr.addElement(""));
#If(sessionScope.Module=="All",vtr.addElement(""),vtr.addElement(t3));
return vtr;
What I have found is that not all data is being returned. I thought this might be due to the date field. So I removed it (changing the view and removing the first add element), and yet I still find that not all data is being returned. I suspect that this might be due to the empty strings being passed, or, that this does not actually work the way I had hoped.
Does anyone know if I can get this working the way I want it to, and if not, do you have any suggestion on how I can go about this?
Date is not needed as the first sortable column in the view. The first column does need to be sorted for the lookup to work just like the Notes view needs to be sorted for #DbColumn and #DbLookup to work. XPages uses the same underlining architecture. This example - http://dev.openntf.org/demos/demoapp.nsf/viewFilteringVector.xsp - works without the data being sorted by Date.
My guess as to why your example isn't working is down to how your Notes view sorted. Try creating a new view with column 1 (email) ascending sort, column 2 (own) ascending sort, and column 3 (module) again ascending sort. You should be able to get vector filtering working in this situation.
If all that doesn't work for you, you might consider multi-layer category filtering (new to 853). This filtering type in XPages is related to how categoryFilter works but allow you to filter a view by the sub-category (or sub-categories) too. This technique might suit your scenario better. Hope this helps.
I have a table that contains three columns.
"UserId" type-nvarchar
"PostAuthorId" type-nvarchar
"Post" type-text
This table will contain "wall" posts like in facebook for each user's page. I am going to use a gridview on each user's page to display the posts. The issue is I want to display them with the latest(most current) post being first and the earliest post being last.
I have never used autoincrement before and I am not sure if that is the answer. If it is, I do not know how to use it. I thought about adding a date posted column and then ordering by date.
If I end up using the date column, I could also display the date on the post. Is there a way to convert the date to a readable format?
What is the best way of implementing this type of ordering?
If you use AutoIcrement the first record will start with 1 and each record will increment from there. (default setting)
If you want to sort them by newest first do an ORDER BY ID DESC
I would suggest making a column called wallPostID then setting that to AutoIncrement and also your Primary Key
Date Formating:
If you are displaying this data in a gridView
Go to Edit Columns on your grid view
CLick on the Date field under "Selected Fields" on the bottom left
Under "BoundField properties" on the right Go to Data -> DataFormatString
{0:d} will display as 1/1/2010
This site has more info in string formatting
http://msdn.microsoft.com/en-us/library/fht0f5be.aspx
A datetime column would definitely work for something like this. Assuming you are using MS-SQL, you can also attach a default value to the column using a built-in function like GETDATE(). That way, you only have to input the data that matters and the database will take care of adding the datetime column.
For converting a datetime to a readable format try:
DateTime postDate;
string value = postDate.ToShortDateString();
You should always use an ID field that auto increments. Can also be used as your PK
I would suggest the DateTime field rather than the autoincrement simply because it will not only serve as an effective Sort field, it also preserves information that you may well want to display. If you want the most recent first you'll sort using the Date and a "DESC" modifier:
Select ... Order By [Date] DESC;
When you retrieve the data, you can retrieve it as a DateTime and modify it using C#. You can use "ToShortDateString()" as suggested by mdresser if you just wish to show the date or ToString("...") if you wish to show the time as well. You can also use SQL to convert it into a string before retrieving it:
convert(Varchar(10), #mydatetime, 101)
If you look in MSDN you'll see the various conversion codes (101 is the code used above) that can be used to translate the date in various ways.
UPDATE: You may want to use an autoincrementing field for your application for reasons other than your expressed need to sort wall entries. They are easy to use - just mark the field as an Identity if using SQL Server (other DBs are similar). As far as using them in your program, just think of the field as an Int field that you never have to set.
Now, why would you use a auto-incrementing field? Perhaps the most straightforward reason is so that they give you have an easy way to identify each record. For example, if you permit people to alter or delete their wall entries, the auto-incrementing field is ideal as it gives you a way to easily look up each record (each record will be assigned its own, unique value). You might put an "x" next to the record like StackOverflow does and make it a call back with the UID (auto-increment) value. Note that you should set up your primary key on the UID field if you'll be doing this.
Now, if you find them useful for this reason then you could also sort by the UID. I would still store the date so that you can provide Date and Time feedback as to when an entry was made on the wall but this would no longer be your indexed or sorted field.
