Hi,

        I used the textbox in edit template for update the values in gridview. But I got the problem(Collection was modified; enumeration operation may not execute.) .Please give me the solution.

My Code behind code:

 protected void RadGrid1_UpdateCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
        {
            GridDataItem id = (e.Item as GridDataItem);
            string Empid = id.OwnerTableView.DataKeyValues[id.ItemIndex]["EmpId"].ToString();
            foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
            {
                TextBox txtleavetaken = (TextBox)item.FindControl("txttakenleave");
                TextBox txtleaveremain = (TextBox)item.FindControl("txtleavecount");
                TextBox txttotalworkdays = (TextBox)item.FindControl("txttotalworkdays");
                TextBox txtadvance = (TextBox)item.FindControl("txtadvance");
                TextBox txtbonus = (TextBox)item.FindControl("txtbonus");
                TextBox txtothers = (TextBox)item.FindControl("txtothers");
                TextBox txttotalsalary = (TextBox)item.FindControl("txttotalsalary");
                objpl.empname = Empid.ToString();
                objpl.takenleave = txtleavetaken.Text;
                objpl.leave = txtleaveremain.Text;
                objpl.totalworkdays = txttotalworkdays.Text;
                objpl.empadvance = txtadvance.Text;
                objpl.bonus = txtbonus.Text;
                objpl.empothers = txtothers.Text;
                objpl.totalsalary = txttotalsalary.Text;
                objbl.updatesalarydetail(objpl);
                fullviewstaff();
            }



Thanks,
Arun.

Hello,

Please try with the below code snippet.

protected void RadGrid1_UpdateCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
    GridEditFormItem item = (e.Item as GridEditFormItem);
    string Empid = item.GetDataKeyValue("EmpId").ToString();
    TextBox txtleavetaken = (TextBox)item.FindControl("txttakenleave");
}


Thanks,

Hello,

To reduce the width of the any control in edit mode, we have to use ItemDataBound event.

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item.IsInEditMode && e.Item is GridEditFormItem)
    {
        GridEditFormItem item = (e.Item as GridEditFormItem);
        string Empid = item.GetDataKeyValue("EmpId").ToString();
        TextBox txtleavetaken = (TextBox)item.FindControl("txttakenleave");
        txtleavetaken.Width = Unit.Pixel(100);
    }
}


Thanks,
Jayesh Goyani
