I have the following scenario where a patient has a list of diseases and I have to show the patient name and the list of diseases as columns in a gridview.
I have the datatable that has patientID, patientName and all the diseases as columns (representing 1 or 0 values based on the disease exists for a member)
If I bind the datatable directly, I will get patient and all diseases with 1 and 0 values
However, I want this gridview to have patientName as one column and all the diseases as other columns and in future if a disease is added, I want a column to be added to GridView as well
The Gridview has patient name under patient Column
and checkbox in everycolumn under a disease (if the disease exists for that member, the checkbox is checked by default during binding)
And as an user, I should be able to check/uncheck those if a new disease affects the patient and update the information to the database.
If, it is a bound field, I am able to do this but inorder to support the case of checkbox and editing, I have to go for a template field and item template, but I am not sure how to do it.
Can you please help me with the code to do that.
Data Table looks like this
Thank you.

I have a simple gsuite app with two data sources. One is a students datasource which stores student name, id, and demographic info. The other is a record of the attendance for the current day and contains name, date, and present (boolean column). Each student is unique and maps to one or more rows in the attendance datasource.
The goal is to be able to pre load the table with a set of students from the students table, leaving the date and present blank. THen the user can go down the table checking the boxes for who is in attendance on that day.
Is there a simple way to pre-load a set of records in the Attendance table based on the students table? Any good examples with explanation?
EDIT:
Here's what a data model might look like:
Students: FirstName:string LastName:string Status:string SiteName:string
Attendance: FirstName:string LastName:string Date:date Present:bool
The Students datasource would contain one record per FirstName, LastName. The Attendance datasource would contain multiple records per student, corresponding to each day that attendance data was captured.
Ideally, when displaying the Attendance table widget, I would pre-populate the table with a list of students for one Site. I already have a date-picker widget that updates all the date column values.
I have a web application where the user enters his qualifications using dropdownlist
1. Subject and
2. Grades
upon save the qualifications are displayed in a gridview which has a select column below the dropdownlist.
To edit user needs to select the row that he wants to edit to display the values in respective dropdownlist for subject and grade.
How do I set the selected value of each dropdown based on subject and grade initially selected.
Thanks
I have ASP.NET GridView in my web app and would like to bind 3 columns with values based on one column. I am providing example below, is it possible to implement into GridView?
My Gridview fields are
Name|Score1|Score2|Score3
I will display the name but how to fill the score fields based on name.there are 3 scores corresponding to each name,that we taken from the same table with a single score field.the 3 scores are provided by 3 different persons.Also i want to display the corresponding score providers name in the header portion of the gridview.
ie,
Name|Ram Score1|Raju Score2|Mohan Score3
How can i do this...
Plz provide the query to do this
Consider to rather calculate the scoring fields in database. Create a stored procedure and bind it to the grid view.
I am writing a web application that is used for tracking and entering some everyday user data... Every day I need to enter some data for multiple users manually...
I will choose the date with the calendar, and for that date I will get DB values assigned for all users on chosen date...If there are some entries in database for that date i will display it in gridview...
Here is the look of gridview for chosen date...
USERS DATA
------------
User1 Data1
User2 Data2
User3 Data3
But, if I choose the date for which there are no entries in DB, I would like to display the gridview containg User names in each row, but I want the second column (DATA field) to be initially editable for ALL rows (the whole second column should contain textboxes for inserting values, not only selected row as in standard editable gridview mode) allowing inserting of wanted values...
I want it to look something like this
USERS DATA
----------------
User1 TextBox
User2 TextBox
User3 TextBox
My idea is to get Users list from DB and create a datatable with first column containg returned user names, and second column empty... This datatable will be datasource for gridview in which I am going to disable editing mode, and in normal (displaying) mode I am going to have TemplateField containg of textboxes bound to that datatable in second column, and labels displaying usernames in first column... When entering all values there will be SAVE button who is calling a method that will read entered values from datatable and save it to database...
Is there a better way to implement this functionality? If Templatefield textboxes are bound to datatable (as gridview datasource) textboxes entered values are going to be accessible from datable object, but Save button click causes postback, and I don't know how to preserve datatable state? Is there a better way to get wanted gridview with whole second column availibe for inserting new values?
Thank you in advance for your help & time!
Try this

I would retrieve the full dataset using a left join in the database, and if there is no entry for a user, that user will be returned with a blank value. Something like this:
select users.user,
isnull(entries.entry,'')
from users
left join entries on users.userid = entries.userid
I think you can override the OnDataBinding (or OnDataBound) method to check and see if the second column is empty, and place the field in edit mode if it is. This way, if some users have entries but some don't, only the users with no entry will be in edit mode. Any user with an entry will be in display mode. There is a sample for this at http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.onrowdatabound.aspx.
I have 2 tables with unique IDs that can be mapped to each other (one table comes from a database outside of my application but has information about the same entities I'm tracking). I want to provide a UI for linking "my" records with the "other" ones, so I can store the "other" IDs in my table for the matching records. In a nutshell, the key UI element is a dropdownlist showing the available (ie, not-yet-linked) records from the "other" table.
I have a gridview for displaying "my" records in each row, plus a column showing some info from the linked record in the "other" table, if any. The data are about buildings and properties, so it might look like this:
Building1 Dallas TX Building1_Dallas_TX
Building2 Memphis TN Bldg2_Memphis_TN
Building3 Denver CO
Building4 Seattle WA
Building5 Boston MA Building5_Boston_MA
where the first 3 columns show some information from "my" table, and the last one shows the matching record from the "other" table, where the records have already been linked, else a blank where no link has been established. My actual gridview has several more columns from "my" table, but this is enough to illustrate the need.
When Edit (not shown) is clicked for a row, I want to be able to edit all 4 columns. The first 3 are textboxes; the last column should be a dropdownlist showing all of the unlinked records from the "other" table, plus an "Unassigned" option (as the first item in the list) so records can be "unlinked" or simply left unassigned, plus (for those rows that already have a link established) the linked item (it's "used" but it needs to be in there so they can continue to use it).
I can populate the dropdownlist correctly in code-behind in the gridview RowEditing event (except for the Unassigned item which I add as a ListItem in .aspx with the AppendDataBoundItems option set to true), and I can set the correct SelectedValue on the ddl's DataBound event, but on postback when I click to Update the row, the ddl has no items in it anymore (except for the Unassigned item) so the link is always cleared. If I set a link manually by directly editing my table, everything looks fine going into Edit mode -- the ddl has the correct items in it and it pre-selects the correct item, but all is lost on the Update postback. I have tried re-binding the ddl at various stages of the page cycle but clearly I don't quite understand that cycle well enough yet because I cannot figure out how to get the user-selected item to update my table.
I've also tried populating the ddl with a SqlDataSource SelectCommand, but have had no luck including the ID of currently-linked records in the other database (even though it's available in "my" table and I set it as a GridView DataKey and add it as a ControlParameter in the SelectParameters for the SqlDataSource. Without the currently-linked record in the ddl item list, I can't keep existing links.
I'll hold off sending a code sample for now -- this message is already too long! -- in hopes that the solution is obvious from what I've described... I don't think my aim is weird, but I'm open to being persuaded otherwise.
Many thanks in advance!

Ok, I'm not going into details with code because maybe you already done what I'm about to suggest.
For the last column, the drop down list, you have to execute an SQL statement to grab you the unlinked items. Use the "WHERE xx NOT IN". For the "Unassigned" option, just add an item to the list in the same code scope as above.
Next step is to handle the GridView's editing events manually. Insert, Update and Delete.
I think that way you won't have problems.
