Hi,

I'm using a rad combo within the grid control. I would like to set an empty message to display the text "Select item" when the page loads or if there's no item selected. But it does not work. I've done a some research on this and from everything I've read I'm supposed to set the "AllowCustomText=True". I've tried it both ways with no success. If I open the combobox and close it without selecting an item the empty message then shows but it doesn't show initially or on load. Can you help?
<telerik:GridTemplateColumn DataField="Item" UniqueName="Item">
                        <ItemStyle />
                        <ItemTemplate>
                          <telerik:RadComboBox ID="ddlItems" runat="server" AutoPostBack="false"
                                DataSourceID="objItems" DataTextField="Items" DataValueField="Items"
                                Skin="Default"  OnClientDropDownOpening="DropDownOpening"
                                OnClientSelectedIndexChanged="ItemValueChanged" EnableViewState="true"
                                AllowCustomText="False"   Width="150px" Height="150px" EmptyMessage="Select Item"
                                ondatabound="ddlItems_DataBound"
                                FocusedStyle-BackColor="#fff6dc" Text='<%# Eval("Item") %>'>
                            </telerik:RadComboBox>
                        </ItemTemplate>
                    </telerik:GridTemplateColumn>
thanks,
Ron.

Hi Ron,

Please remove the Text property of the RadComboBox and see if it helps.Please try the following code snippet.

ASPX:
<telerik:GridTemplateColumn DataField="Item" UniqueName="Item">  
    <ItemTemplate>
        <telerik:RadComboBox ID="ddlItems" runat="server" AutoPostBack="false" DataSourceID="objItems"
            DataTextField="Items" DataValueField="Items" Skin="Default" OnClientDropDownOpening="DropDownOpening"
            OnClientSelectedIndexChanged="ItemValueChanged" EnableViewState="true" AllowCustomText="False"
            Width="150px" Height="150px" EmptyMessage="Select Item" OnDataBound="ddlItems_DataBound"
            FocusedStyle-BackColor="#fff6dc">
        </telerik:RadComboBox>
    </ItemTemplate>
</telerik:GridTemplateColumn>

Thanks,
Princy

Princy,

Thanks for replying but that did not work either. I also tried it with removing the text property and setting the AllowCustomText property to true and that also did not work. Any other suggestions?

Hi Ron,

The code works fine at my end,Below is the code I tried.

ASPX:
<telerik:GridTemplateColumn>
    <ItemTemplate>
        <telerik:RadComboBox ID="RadComboBox1" runat="server" DataSourceID="SqlDataSource1"
            DataTextField="ShipCountry" DataValueField="ShipCountry" AllowCustomText="true"
            EmptyMessage="-- Select item --">
        </telerik:RadComboBox>
    </ItemTemplate>
</telerik:GridTemplateColumn>

OR add from code behind as follows if it doesn't show from ASPX.

C#:
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = (GridDataItem)e.Item;
        RadComboBox combo = (RadComboBox)item.FindControl("RadComboBox1");
        combo.AllowCustomText = true;
        combo.EmptyMessage = "Select an Item";
    }
 }

Thanks,
Princy
