Error when deleting record from a gridview

[Queen Soso]

hi all,

I have this error when I click delete link in the gridview:

'unable to cast object of type 'ASP.WebForm1_aspx' to type "system.Web.UI.WebControls.GridviewRow'

I really need help as soon as possible :(

Explicit conversions (casts) require a cast operator. The source and destination variables are compatible, but there is a risk of data loss because the type of the destination variable is a smaller size than (or is a base class of) the source variable.

So you can try this:

Gridview gv = (Gridview)sender
//Your code here

what do u mean by sender?

my line is already casted to (GridviewRow).

I hope this example will make the conception clear:

class Test
{
    static void Main()
    {
        double x = 1234.7;
        int a;
        // Cast double to int.
        a = (int)x;
        System.Console.WriteLine(a);
    }
}
// Output: 1234

'unable to cast object of type 'ASP.WebForm1_aspx' to type "system.Web.UI.WebControls.GridviewRow'

Basically you are trying to case form type to GridviewRow type.
Sanji told you to typecast it....

Use like this.

GridviewRow myGridRow = sender as GridviewRow;
