GridView dynamic column with editable, i am creating a grid which is dynamic and can be update and delete record, In the the of bind grid i use Edititemtemplate for bind textboxes with ID in it. when click on edit button.

in rowupdating event i am unable to get old and new values of textboxes for update record.

What I have tried:

Dim name As TextBox = DirectCast(GridView1.Rows(e.RowIndex).FindControl("txt_Name"), TextBox)

Here txt_name is ID of textbox.

but not working

Ensure you have a valid RowIndex
And try using a GridViewRow as follows;
Dim gvrEdit as GridViewRow = gridView1.Rows(e.RowIndex)
Dim txtBox as TextBox = DirectCast(gvrEdit.FindControl("txt_Name"), textBox)
Additionally, ensure that in your RowEditing event handler make sure you set the gridView1.EditIndex

Kind Regards

If FindControl does not return your control then the ID you are using is incorrect. If you load the page in a browser window & then view the source you can see what the actual control's ID is.
Alternatively use your debugger, in your RowUpdating event handler get the GridViewRow & look at what controls it contains using the "Locals" window.
This should allow you to identify the actual controls that are contained on your row

now it is working, in dynamic template grid view , grid lose it's currentstate and not able to find textboxex. i have use griddatabind() on pageload() then it can find the textbox using ID.

but one problem occur :
the page load event gets fires, but it just skips the SelectedIndexChanged event for the dropdown how to resolve this.
