I am binding some records to gridview, the binding process is done correctly and also iam adding commandfield for editing and deleting. When i am editing first time all the cell value go to the corresponding textboxes or other controls, editing is worked perfectly. But the problem is that when i am editing another record in the gridview the row become textboxes like template field.Please help me.I think this is an unexpected behaviour.

Look at the screenshot you get what is my pblm

Update:

C#

public bool Bind(string Query, GridView grdView) 
{
 sqlFunc = new DB.SQLFunctions();
 DataTable dTable = sqlFunc.ReturnDataTable(Query);
 grdView.DataSource = dTable;
 grdView.DataBind();
 return true;
 }

Solution 1

From the above scenario only thing I can guess is that you are calling the Bind() method from Page_Load event handler without checking IsPostback property.

If you call Bind() method from Page_Load, try like

C#

if (!IsPostback)
{
    //YOUR CODE GOES HERE
    //
    Binding(YOUR_QUERY, gridView);
}

In VS 2008 there is no pblm.In 2010 the gridview behavior is changed while editing

In that case, zip your sample code, upload in dropbox or something and give URL. I will check and let you know.

I think this is not a pblm in code.It's work .net 3.5 gridview.but in 4.0 the gridview become like second screen shot.I send u the code to your mail id.please send your mail id

Upload somewhere like dropbox.com or skydrive.live.com and provide URL. I will take it from there.
