从Gridview1删除行

Question

I am trying to delete a row in my gridview but im having a problem with the delete extension method.

Error im getting:

'System.Web.UI.WebControls.GridViewRow' does not contain a definition for 'Delete' and no extension method 'Delete' accepting a first argument of type 'System.Web.UI.WebControls.GridViewRow' could be found (are you missing a using directive or an assembly reference?)

Here is my code:

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName.Equals("Submit"))
    {
        GridViewRow oItem = (GridViewRow)((LinkButton)e.CommandSource).NamingContainer;
        int RowIndex = oItem.RowIndex;
        GridView1.Rows[RowIndex].Delete();
    }
}

Answer 1

Try to do this using a different approach by looping thru the DataGridView's Selected Rows

if (e.CommandName.Equals("Submit"))
{
    GridView1.DeleteRow(GridView1.SelectedIndex)
    //you could null the datasource here and reassign if necessary here prior to calling DataBind()
    GridView1.DataBind();
}
