Above is the look of my gridview.

the textbox is set to read only = true 

what i want is, when the edit button is click, the the textbox of that row can change to read only = false .

when the textbox become editable, the column data should remain, and let user to edit. once they finish edit and press the update button ( adding in later), the db will be update by the latest edited record.

 Anyone have any idea??

Help are highly appreciated!

if ur Template Field like this do like this

<asp:TemplateField HeaderText="Problem">

<ItemTemplate>

</ItemTemplate>

<EditItemTemplate>

</EditItemTemplate>

</asp:TemplateField>

for change Textbox in Gridview to Read only false

and Click on Edit Template >>> select your Column  you will see textbox in that Column and click on textbox

so you will change its to read only
