ASP.NET - Persist A GridView's Dynamically Chosen DataSourceID Over Multiple Button Clicks?

Nov 11, 2009

I have an app where I need to dynamically choose an SQLDataSource for a GridView so I can use 1 of 2 stored procedures, depending on who is logged into the system. My problem is that I am using logic like this, in the button click...

If Session("SiteType") = "Type1" Then
GridView1.DataSourceID = "SqlDataSource2"
Else

[code]....

This happens when you click the button that reveals the panel with the gridview in it. The user then makes changes (basically adjusting a text box on one or more liens of the grid) and then clicks "save". However, the gridview no longer knows its DataSourceID once this happens, so when I try to go through the gridview's rows - there are none.

If, in the save button's click, I put the same code, it (of course) blanks out any of the data changes I made in the form. So, simply put - how do I dynamically choose the SqlDataSource, but only one time, so that the program then keeps that SqlDataSourceID associated with the gridview until the end of the cycle? Is this a ViewState thing? I don't totally understand ViewState...

Dynamically Assign A BackColor To A GridView Row?

Nov 29, 2010

I'm working on an ASP.Net page containing a GridView, which is populated with customer orders returned by a stored procedure. What I'd like to do is dynamically change the backcolor of the GridView rows to indicate priority.

The stored procedure returns an integer indicating the records priority, I think I just need to translate the integer to a color, then make the GridView row display it.

Asp.net - Adding Linkbutton Dynamically To Gridview. Not Firing?

May 8, 2012

I am dynamically adding a link button to every cell in a gridview. Adding the button works however the firing of the even handler doesn't. i need the linkbutton to call a function and pass some data for processing. My code is below. I have found solutions from the site that have gotten me this far.At the moment the gridview loads the cells with buttons in blue. when you click them they go back to plain text and no function is called.

Asp.net - Refer To Footer Value In GridView Created Dynamically ASP VB

Jun 4, 2009

I have a Gridview that I create a dynamic footer wired up to the RowDataBound event.

However there is a 50/50 chance that 3 of the columns will have no data.

I want to be able to dynamically hide the columns with no data if possible.

I have tried doing this in the RowDatabound event by checking if the value is = 0 but that does not work because I think the event is called to early?

Is there anyway to refer to the values in the Footer row after ALL the data has been bound?

Ideally in VB

`Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then

C# - Dynamically Populating Column Headers In A Gridview?

Mar 6, 2012

I have a vb.net website with a gridview that currently has exam questions displaying vertically in each row like this:

Name question answer
-----------------------
Joe question1 answer1
Joe question2 answer2

But I would like to change it, so that each question is a header, like this:

Name question1 question2 question3
----------------------------------
Joe answer1 answer2 answer3
Jill answer1 answer2 answer3

This makes it more readable since each user is only listed once.I would like to stick with a gridview instead of rewriting all my code.I am actually binding my data to the gridview via some other programmers class. I am using LINQ like this:

Return (From entry In report.FetchAllEntries()
Select questionID = entry.Question.QuestionID,
userID = entry.Session.User.ID,

Asp.net - Dynamically Populating A DropDown Template Control In A Gridview?

May 3, 2012

I have a GRIDVIEW with columns, one of which contains a CSV of possible values for the dropdown that must appear on each row.

Private Sub GridViewParameters_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewParameters.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then[code].....

Depending on whether the type of control is a dropdown, textbox, or check box (feined in the table) it hides or shows the relevant control type. If it is a dropdown it needs to get its values from a CSV in a corresponding column. I have a SP that returns a these in table form if passed the id of the relevant row.How do I get that is from the gridview to pass to the drop down and load it correctly?

Asp.net - Format Dynamically Generated Column Headers Of GridView?

Jun 27, 2012

I have created a Stored Procedure in SQL which produces a pivot table. I've successfully created a GridView in ASP.NET to display this data.

However, some of my column headings are dynamically generated from the data (AutoGenerateColumns=True), and those column headings are just dates, so they will look different almost every time the table is generated.

This all works fine, except that the date format of the column headings is wrong. I know I could change the way SQL produces the dates in its output, but I don't want to do it that way. I want to control it from the web page.

I didn't think this would be difficult - I thought I could just do something along the lines of finding the cells in the header row and changing the datastringformat. The problem is that whether I put my code in the GridView's DataBound or RowDataBound event, the cells in the header row seem to be empty, so I can't reformat them. It's as if the headers get populate some time AFTER the DataBound event, but I don't know when or how to trap it.
