Please help by providing solution as soon as possible

Are you preforming a DataBind on the GridView in your Page's Load or PreRender event?

Could you please provide more information about what the problem is?

What do you mean by "can't edit the GridView"?

Does this mean that the fields don't become editable when you click the edit button...does this mean that your data source is not updated when the user clicks the update button...what exactly is going wrong?

Hi Frinny,

Thank you for your response.

Your correct.The fields donot become editable and also datasource is not updated when user clicks the update button.

I am binding the values in page load event.
and the same problem is happeninng for dropdown boxes.I have three cascading dropdownlists.Once the user selected the first dropdown list item then the second dropdown list gets enabled and the items will append to the second one.But this is not going fine.If i again reload the page then the items are appending.

So please help me what i am missing out here.


Regards,
Mohan.

Move the databind to the Page's PreRender event instead.
When you do the databind in the Page Load event the source is reset back to what it was originally and the editing will never take place.
