How to do GridView RowUpdating event

I am trying to perform an update action in GRID VIEW control in asp.net.

My code:

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    TextBox t1 = new TextBox();

    t1 = (TextBox)GridView1.Rows[Convert.ToInt16(HiddenField1)].Cells[3].Controls[0];

}

When I run, I get the error as "Unable to cast object of type 'System.Web.UI.WebControls.HiddenField' to type 'System.IConvertible"

Can anyone help me in suggesting a solution for this?

I think you meant to use the .value property, as in HiddenField1.Value:

t1 = (TextBox)GridView1.Rows[int.Parse(HiddenField1.Value)].Cells[3].Controls[0];

It looks like, before, you were trying to convert a HiddenField control into an int, which isn't going to work. Also, you can just use int.Parse to convert the value stored in the HiddenField into an int.
