DataPager, change count items - asp.net

I'm using a DataPager control, I want to change count items on each page.
For example :
the First page 6 rows, the second page 311, the third page 12, etc.
Is it possible? If so, how?

my advice is to do it manually, make your own sql query and customize the page size as you want
here are some tips that can help
to get range of rows that are needed for pagination user the row number
MS-sql row number
use the TOP to get the upper set of rows
select TOP 5 * from ....
for sure you'll need to get specific row numbers that will be displayed in the current page
select (--get row number--) from tbl_smth where row_num>5 and row_num<10
were as i guess that you have the page sizes in an array so you have to count them to determine the two numbers {5,10}
hope this will help

Page break inside grouping

I have implemented tablix inside tablix concept. I done this with the help of following link.
I have one table A, that is holding other two tables B & C respectively. I have grouped these two tables with the help of Dept_Nbr from first table A.
What I want is:
I want to give page break in between two tables. For example, I have Dept_Nbr as 529 and 530. In one page, the two tables will show the records for 529 and in the other page the two tables will show the records for 530.
Now I want to show all these records in four pages. first table is in one page and second table is in other page for 529th Dept_nbr and vice versa for 530.
How to give Page break inside grouping.
What I tried is:
I gave Page Break on Group Properties, Hence Page is breaking in between two groups. But I want a page break inside a group itself.
Also I checked the check box on tablix properties i.e.., Add Page Break Before and Add Page Break After. But nothing gives the output as it is already in grouping.
Please guide me on the same. Thanks in advance.
Add a parent group to Table A that encompasses the rows containing Tables B & C. For this parent group, group on Department Number. Then, as part of the group properties, you can have it break between groups.
As your question and layout stands now, you're asking that the report break between detail rows. As far as I know, this is not possible.

Filtering data and Display Heading based on filters

being a newbie to SSRS, I am trying to figure out the following:
say for instance I have a dataset which does a :
SELECT [cols...] from [some view]
I want to be able to further filter this based on parameters given from an ASP.NET site (I am using the AJAX control toolkit for the report viewer). There could be x amount of parameters and potentially can be filtered on 1 or more columns.
First question is, how would I filter the dataset and pass along the parameters along with which field the filter should apply to? I may have [col1] and I want to filter it with x values.
Second question Is, I want to be able to group the results per page based upon a column. So for each grouped result set, I want them to be displayed per page (per group per page).
Then on the headers of the page, I want it to display what the page grouping is. How would I do this?
In terms of what have I tried - nothing as I DO NOT KNOW HOW, it is why I am asking the question here to see what the experts (you) can suggest and guide me.
thank you!
To do this you can create Parameters in SSRS, they do not need to be in your query or anything. Then, go to your tablix and click either ROW or column depending on the filter type and set it show/hide visibility. For example I have a report that has personal information, so i have true/false parameter that hides/shows those columns, similar I have one that hides/shows any row with a -1 for the total paid.

RDLC report footer with value from "Current Record"

I don't know if its possible or not, but thought I'd ask. Many times reports need data grouping to have anchored to the bottom of the report some summary information, such as invoices. You don't want the totals shifting UPwards based on only 2 detail lines vs another with 20. I've tried working with using the Tablix bound to the data source for the output but couldn't get it quite right... It would either shift up, or force break and appear at top of following page.
So, if anyone has some ideas to help resolve that, that too would be great.
My second approach was to just use a simple report page footer. However, the overall "Report" page is not technically "BOUND" to any datasource. So, if I put a textbox in the footer and want it to show something, I can't pick "the most recent row from the datasource associated with the Tablix", it always requires an aggregate, such as
=First(Fields!SomeField.Value, "SomeDataSource" )
=Sum( ...
=Last( ...
etc...
I just want it to have whatever was the most recent... so I tried to use report variables to create one and was thinking to have it get updated per row being processed, so it always had whatever the "latest" value was and I could just dump that value at the bottom of the report.
Any suggestions to either would be great. Thanks.
I know this is an old question, but I had a very similar problem and came up with a unique solution. I had a statement that needed to have the payment slip print at the bottom of the page even if the statement line items wrapped over to another page. I solved it by:
Making all rows in the report a uniform height.
Calculating how many rows were required to fill the page (minus the height of my payment slip.
Getting the number of line items in the statement.
Calculating the remaining number of rows needed to push my payment slip to the bottom of the page.
Adding a sub-report with the calculated number of blank rows to pad out the necessary space between the line items and the payment slip.
The advantage of that approach was that I could generate bills for multiple customers, and since the padding is part of the group it would be customized for each customer's bill and bottom-justify the pay slip for each of them.
You can use a similar approach to push your "footer" info to the bottom of your page. Since it is still inside of your data group you'll have access to the data values you need as well.
In the footer you can refer to report item from report body, like this:
=ReportItems!myFooterValueTextBox.Value
The catch is that you can refer to only one report item in your footer, so you may need to add invisible footer row in your table and concatenate all your totals into one cell (myFooterValueTextBox) in that row:
=First(Fields!SomeField.Value, "SomeDataSource") + "|" +
Sum(...) + "|" + .... +
Last(...)
I used pipe as deliminator in my example, so then in the footer, I would split the string and place values in appropriate containers, like this:
=Split(ReportItems!myFooterValueTextBox.Value,"|")(0)

Limiting gridview row selection in ASP.Net web page

Have a gridview control which will show X amount of rows. I want to the user to be able to select y number of rows, but limit the maximum selected rows to a set view, such as 3. If the user tries to select a fourth row I don't want them to be able to until they unselect a row.
Anyway to do this?
Thanks
Since the GridView works with single selections, how are you allowing them to select the values in the first place, on the client or server? If on the client, you can use JavaScript to do this; simply store an array of the table rows that are selected, if the length is three, then block adding to the array until the user deselects...
Please update how you are doing it, and I can post further.

How to count Number of Rows devexpress xtragrid

I am using Devexpress XtraGrid Control, Here I can count the number of rows in footer of grid. but for this I need to set count property of SummeryItem in grid for at least one column. I dont want to do like this.
I want count number of rows in xtraGrid without referring any one column in grid. I just want to show number of rows count. when user will filter that rows, at that time count also need to be changed.
Is there any option to show this number in Group header panel?
I'd use BaseView.RowCount to get the row count and draw it within CustomDrawGroupPanel event.
You can use the customsummarycalculate event to count the number of rows currently shown in the filtered collection and display it in the summary area (generally, I put that text in the summary area of the ID field for the collection I'm using - as I never have a need to put anything else there).
I don't know if this is an update but:
int i = view.SelectedRowsCount;
