a gridview with combobox in user control issue

[Daniel Kuo]

Hi :

I got a strange error message about a gridview with combobox in user control issue

we use combobox in user control, then we put the user control in gridview

this is the user control(ASCX) code fragment

<%@ Control Language="C#" AutoEventWireup="true" Codebehind="UC062.ascx.cs" Inherits="VMI.Web.Controls.UC062" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
 
<telerik:RadCodeBlock ID="RCB1" runat="server">
<script type="text/javascript" language="javascript">
       function RadComboBox2_OnClientFocus() {
       }
</script>

<table cellspacing="0" cellpadding="0" border="0">
    <tr>
        <td width="10%">
                <telerik:RadComboBox ID="RadComboBox2" runat="server"
                EnableLoadOnDemand="True"                      
                HighlightTemplatedItems="True"
                ItemRequestTimeout="500"
                AllowCustomText="True"
                NoWrap ="true"
                ShowWhileLoading ="true"
                Height="100%"
                DropDownWidth="180px"
                MarkFirstMatch="True"           
                OnItemDataBound="RadComboBox2_ItemDataBound"  
                OnItemsRequested="RadComboBox2_ItemsRequested"               
                OnClientFocus="RadComboBox2_OnClientFocus" 
                                          
                OnLoad="RadComboBox2_Load" 
                OnSelectedIndexChanged="RadComboBox2_SelectedIndexChanged"
                ShowToggleImage="False"                
                Skin="Inox">               
                             
                </telerik:RadComboBox>
                            
                </td>
   </tr>
</table>

this is ASPX Page code fragment

<asp:GridView ID="dgiPipeLineItem" CssClass="cellPadding" runat="server" AutoGenerateColumns="False"
                        Width="100%" meta:resourcekey="dgiPipeLineItemResource1" BorderWidth="1" BorderColor="#cacaca"
                        OnRowDataBound="dgiPipeLineItem_RowDataBound" OnRowCancelingEdit="dgiPipeLineItem_RowCancelingEdit"
                        OnRowEditing="dgiPipeLineItem_RowEditing" DataKeyNames="ID" OnRowUpdating="dgiPipeLineItem_RowUpdating">

                        <RowStyle CssClass="table_11" />
                        <AlternatingRowStyle CssClass="table_10" />
                        <Columns>
                            <asp:TemplateField HeaderText="xxx" meta:resourcekey="TemplateFieldResource2">
                                <ItemStyle HorizontalAlign="Left" />
                                <EditItemTemplate>
                                    <uc3:UC062 ID="uc_SupportDeptEdite" runat="server"  OnSelectedIndexChanged="uc_SupportDeptEdite_OnSelectedIndexChanged" />
                                </EditItemTemplate>
                                <ItemTemplate>
                                    <asp:Label ID="lblSupportDept" runat="server" Text='<%# Eval("SupportDeptName") %>'></asp:Label>
                                </ItemTemplate>
                                <FooterTemplate>
                                    <uc3:UC062 ID="uc_SupportDeptFooter" runat="server" OnSelectedIndexChanged="uc_SupportDeptFooter_OnSelectedIndexChanged" />
                                </FooterTemplate>
                            </asp:TemplateField>
                        </Columns>
                    </asp:GridView>


when the page loaded

we got a java script error in vs2008: Microsoft JScript 執rumtime error: 'RadComboBox2_OnClientFocus' undefined

but we found other server side combobox event is ok. only the client side event (in this example, OnClientFocus event).

Can you help us with this issue?

thanks

Hi Daniel Kuo,

Please try the following:

1. Put the closing tag of RadCodeBlock. You need to close it after the javascript
2. Add parameters to the event handler

<telerik:RadCodeBlock ID="RCB1" runat="server">
<script type="text/javascript" language="javascript">
       function RadComboBox2_OnClientFocus(sender, eventArgs) {
       }
</script>
</telerik:RadCodeBlock>

Let us know how it goes.

All the best,

Hello Daniel Kuo,

Thank you for the provided project. It helped us identify the problem and the solution.

What you need to do is to replace the RadCodeBlock with RadScriptBlock in your web user control as below:

<telerik:RadScriptBlock ID="RCB1" runat="server">
    <script type="text/javascript" language="javascript">
        function RadComboBox2_OnClientFocus(sender, eventArgs) {
            alert("on focus");
        }
    </script>
</telerik:RadScriptBlock>

I hope this helps.
