[Solved] RadComboBox in EditFormSettings - how to find it ?

[Krzysztof]

Hi

I have code :

<telerik:RadGrid ID="GridAdvert" runat="server" >
         <MasterTableView DataKeyNames="id" >
           <EditFormSettings EditFormType="Template"  >
            <EditColumn UniqueName="EditCommandColumn1">
            </EditColumn>
             <FormTemplate>

                  <telerik:RadComboBox ID="findCompanyBox" runat="server" Skin="Inox"
                    AllowCustomText="True" ShowToggleImage="True" ShowMoreResultsBox="true"
                    EnableLoadOnDemand="True" EnableVirtualScrolling="true"
                    Width="200px" Height="200px"
                    ZIndex="10000" OnItemsRequested="findCompanyBox_ItemsRequested" >
                    <CollapseAnimation Duration="200" Type="OutQuint" />
                  </telerik:RadComboBox>

             <asp:Button ID="UpdateButton" OnClientClick="Save(this, event);" Text="Save"
                    runat="server" />
            </FormTemplate>
           </EditFormSettings>
          </MasterTableView>
         </telerik:RadGrid>

in code behind I have :

protected void findCompanyBox_ItemsRequested(object o, Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs e)
{
   RadComboBox findCompanyBox = new RadComboBox();
   findCompanyBox = (RadComboBox)GridAdvert.FindControl("findCompanyBox");
}

After I call :
findCompanyBox = (RadComboBox)GridAdvert.FindControl("findCompanyBox");
... I get > findCompanyBox = null

My question is . How can I find RadComboBox control in Girid FormTemplate ???

Hello,

You can try the following code to access the RadComboBox in Grid EditFormTemplate in the ItemDataBound event of the RadGrid.
cs:

protected void GridAdvert_ItemDataBound(object sender, GridItemEventArgs e)
    {
       if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
          {
              GridEditFormItem item = e.Item as GridEditFormItem;
              RadComboBox  rdcbx = (RadComboBox )item.FindControl("findCompanyBox")
          }
    }

Thanks
Princy.

Hi

It work well. Thank You.
But I have another problem with display RadComboBox items.

I code behind I have :

protected void findCompanyBox_ItemsRequested(object o, Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs e)
    {
for (int i = itemOffset; i < endOffset; i++)
 {
    RadComboBoxItem boxItem =
                    new RadComboBoxItem(data.Rows[i]["companyName"].ToString(), data.Rows[i]["companyName"].ToString());
    boxItem.Font.Size = FontUnit.Point(8);
    FindCompanyBox.Items.Add(boxItem);

  }
}

When I match items for ComboBox, I canot see the items. I can see border and footer of ComboBox but item content disapear. I cannot see background of items too.  Why ??

Hi Krzysztof,

Here is a code library submission which explains how to access controls in a Grid template on the client side. Go through it and see if it helps to some extent.
