Hi

 I have a GridNumericColumn in my RadGrid (with automatic updates).  Depending on the data loaded the GridNumericColumn may or may not be editable.

How can I set the ReadOnly of the GridNumericColumn in ItemDataBind?

<telerik:GridNumericColumn HeaderText="Quarter1" HeaderStyle-Width="5%" ItemStyle-Width="5%" HeaderButtonType="TextButton" DataField="quarter1" UniqueName="quarter1" AllowFiltering="false" DecimalDigits="0" MinValue="0" MaxValue="999999999" ></telerik:GridNumericColumn>
                    

protected void grdForecasts_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem)
            {
                GridDataItem item = e.Item as GridDataItem;
                if (item != null)
                {
                    DataRowView dataItem = ((DataRowView)item.DataItem);
                    TableCell Quarter1 = item["quarter1"];
                    switch (DateTime.Now.Month)
                    {
                        case 4:
                        case 5:
                        case 6:
                            Quarter1.ReadOnly = true; // This is not working
                            break;
                    }
                                     
                }
          }
    }

Kind regards

 Suzy

Hello Suzy,

You can use the cell and find the RadNumericTextBox inside. Note that you would need to ensure that the item is in edit mode. When the row is not being edited the RadNumericTextBox will not be rendered.

If you would like additional information on how you can access controls in the cells or rows of RadGrid you would find the following article interesting.


The ItemDataBound event would look similar to the following:


protected void grdForecasts_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridDataItem item = e.Item as GridDataItem;
 
        if (item != null)
        {
            DataRowView dataItem = ((DataRowView)item.DataItem);
 
            TableCell cell = item["quarter1"];
 
            RadNumericTextBox numericBox = cell.Controls[0] as RadNumericTextBox;
 
        }
    }
}
