In my form I have four text boxes (2 in each row); Textbox_FN1, Textbox_LN1 in row 1 and Textbox_FN2,Textbox_LN2 in row 2. When a button is clicked; I want to pass the row number to the following procedure which needs to read values from two text boxes and write to DatagridView. The code below writes the literal "Textbox_FN1.txt" but I need actual value from the textbox control.

after calling `GridView3.DataBind(), why do i still get Index was out of range. Must be non-negative and less than the size of the collection.

I have an unbound Gridview that is populated by a Linq to Entities query and would like to convert string values in a particular column to lowercase. In the Gridview's RowDataBound event, I have tried StrConv(e.Row.Cells(3).Text, VbStrConv.ProperCase) but this doesn't work. I have also tried StrConv(emp.Name, VbStrConv.ProperCase) in the LiNQ to Entities query but still the Name values returned are to converted to Lower-case.

I have a DataTable that is bound to my GridView via a method a created. The function returns a new DataTable each time, so I don't have direct access to the data that is in the DataTable.
I'm trying to update my database with the data from the DGV, but anytime I try accessing the columns or rows, I get an error saying the column/row index isn't correct.
I'm using the RowValidatedEvent and if use the following code in a dummy project while manually adding the columns, the result is predictable.
VB.NET
MessageBox.Show(dgv.Item(e.ColumnIndex, e.RowIndex).Value.ToString)
But when I do the same with my bound DGV, I get the exception mentioned above. This leads me to believe that I need to access the DataTable directly, but I can't because I get it from a method.
So is there a way to access the grid view's bound data? I've been playing around with various properties, but have come up short so far.

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?

I am stuck at a task. What I want is, I am creating a table in the database on the fly in the code behind using the below code(in VB).Now my main problem is I want to display this table which is created in step 2 of a wizard, in step 3 using a GRIDVIEW. But as we all know a GridView needs a sqldatasource for values to be displayed, however what I need for achieving this is dynamically assign a datasource to the GridView, but I am not figuring out HOW?

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?
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.

View 2 RepliesI have a GridView control which I am dynamically binding to a DataTable which is populated by a query built based on a set of selected options.What I am trying to do is simply handle the RowDataBound event in order to format specific rows based on the value of a database field. The code in this event handler works fine. My problem is, calling this event causes the GridView to only display the first record in the DataTable, almost as if the Gridview stops after binding to the DataTable after the first row is bound. I have attempted adding the handler dynamically, but I get the same results.I know for a fact that there is sufficient data being returned (the DataTable fills with all of the records, and the GridView shows all the records fine when not touching the RowDataBound event).
I'm adding the handler immediately after generating the query, filling the DataTable, and binding the GridView: [code]I have also determined that, when handling RowDataBound, the GridView's DATABOUND event never gets fired; it seems to stop binding right after binding the first row.
