Read-only controls for editing

[Eliyahu Goldin]

In my grid I have some columns that I need to make read-only in the EditingForm. The problem is that setting ReadOnly="true" makes these columns disappear from the editing form.

<telerik:GridBoundColumn DataField="Description" HeaderText="Delivery Method" SortExpression="Description" ReadOnly="true" />
<telerik:GridDropDownColumn DataField="DeliveryCategory" HeaderText="Delivery Type" UniqueName="DeliveryCategory"
   DataSourceID="sdsDeliveryCategories" ListTextField="Name" ListValueField="Value"
   FilterListOptions="AllowAllFilters" DropDownControlType="DropDownList"
   EnableEmptyListItem="false" ReadOnly="true"
   />

A workaround I am thinking about is to replace GridBoundColumn and GridDropDownColumn with GridTemplateColumns, put a textbox and a dropdown list inside and set for them Enabled=false. Is there an easier way?

Hello Eliyahu,

Other possible approach is to set ReadOnly programatically in ItemCreated:

if(e.Item is GridEditableItem && e.Item.IsInEditMode)
{
    ((e.Item as GridEditableItem)["YourBoundColumnUniqueName"].Controls[0] as TextBox).ReadOnly = true;
}

Hello Eliyahu,

I would suggest you to disable the TextBox of the GridBoundColumn and DropDownList of the DropDownColumn, when in EditMode as shown below rather than using TemplateColumns.

aspx:

  <telerik:GridBoundColumn DataField="ProductID" DataType="System.Int32" HeaderText="ProductID" UniqueName="ProductID">
  </telerik:GridBoundColumn>
  <telerik:GridDropDownColumn HeaderText="UnitPrice" DropDownControlType="DropDownList" UniqueName="UnitPrice" DataSourceID="SqlDataSource1" ListValueField="UnitPrice" ListTextField="UnitPrice" DataField="UnitPrice">
  </telerik:GridDropDownColumn>

cs:

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            GridEditableItem edititem = (GridEditableItem)e.Item;
            TextBox txtbx = (TextBox)edititem["ProductID"].Controls[0];
            txtbx.Enabled = false;
            DropDownList ddl = (DropDownList)edititem["UnitPrice"].Controls[0];
            ddl.Enabled = false;
        }
    }

Thanks
Princy.
