I have a dropdownlist("ddlTemplate") control and a gridview("gvPlanning") control with 1 BoundField column, 1 TemplateField column and remaining columns will be generated dynamically from database.In TemplateFiled Column i have 3 image buttons viz: Edit,
update and cancel.
Gridview will be populated based on the selecteditem of dropdownlist.
if i click on edit imagebutton, i need to add textboxes dynamically in all the columns of that row except first 2 column. And if i click on Update imagebutton i need to retrieve the textbox values.
we can add template field column for textboxes also, but why i am sticking to this method is.. the number of columns changes depending on the selecteditem from the dropdownlist. Eg: If i select india from dropdownlist the number of columns in the gridview
would be 4 and if i select UK from dropdownlist the number of columns would be 9 likewise.
Please help me and thanks in advance..

If you set EditIndex and DataBind, the AutoGenerated BoundFields for that Row will go into Edit mode. That's done with TextBoxes.

Thank you for the response. My doubt here is, how to retrieve data from these textboxes on postback.
Thanks in advance.

In the event of clicking update button you can get the edit row and access the TextBox in that row and get its text. I suppose you handle the RowUpdating event when you click Update button. Then do this:
TextBox tb = (TextBox)GridView1.Rows[GridView1.EditIndex].FindCotnrol("TextBox1");
string var = tb.Text;
No matter you use template or dynamic column, just give the control id to find the TextBox. If you don't know the id, just access the first control in the cell: (TextBox)GridView1.Rows[GridView1.EditIndex].Cells.Controls
