Hi all,

I have been playing around with the possibility of enabling users to enter a new url into a radcombobox if it doesn't exist in list already. I have the following markup in my grid <FormTemplate> which pulls its data from a table named tblUrls:

<telerik:RadComboBox ID="UrlComboBox"  
                     runat="server"  
                     HighlightTemplatedItems="true" 
                     AllowCustomText="true"  
                     Skin="Windows7"  
                     Width="365px"  
                     Height="150px"  
                     DataSourceID="UrlDataSource"  
                     DataTextField="Url"  
                     DataValueField="Url" 
                     SelectedValue='<%# Bind("Url") %>'  
                     AppendDataBoundItems="true">

<Items> 
        <telerik:RadComboBoxItem Text="[Not Defined]" Value="" /> 
    </Items> 
    <FooterTemplate> 
        <telerik:RadTextBox ID="tbNewUrl" runat="server" Skin="Windows7" EmptyMessage="Add a new Url here..."/> 
        <br /> 
        <asp:Button ID="AddUrlBtn" runat="server" Text="Add Url" OnClick="AddUrlBtn_Click" /> 
    </FooterTemplate>

</
telerik:RadComboBox> 

I have tried getting access to the tbNewUrl radtextbox inside the RadComboBox in the c# code behind to no avail. I need the AddUrlBtn_Click to save whatever value is put in by the user to the database when the grid is in insert or edit mode. I have the database INSERT code already worked out but getting access to the RadComboBox and the newly inputted url data is proving to be a real pain. I am sure it is real simple, but patience has run out on this one and I am forced to try another way of doing this if I can;t get it resolved quickly.

I have tried:

protected void AddUrlBtn_Click(object sender, EventArgs e) 
    TextBox Urltxt = (TextBox)UrlComboBox.Footer.FindControl("tbNewUrl"); 

if ((!String.IsNullOrEmpty(Urltxt.Text))&&(UrlComboBox.FindItemByText(Urltxt.Text) == null)) 
    { 
        UrlComboBox.Items.Insert(0, new RadComboBoxItem(Urltxt.Text)); 
        UrlComboBox.SelectedIndex = 0
        Urltxt.Text = String.Empty; 
    }
}

I have also tried:

TextBox AddUrlText = (TextBox)this.Page.Master.FindControl("ContentPlaceHolder").FindControl("tbNewUrl"); 

inside the buttons click event - AddUrlBtn_Click but it can't find the control???

The grid is ajaxified too but when I click the AddUrlBtn in its current condition the page does a full postback as well whilst in insert/edit mode which is undesirable.

Any help with this would be greatly appreciated to I can move on with this project.

Thanks in advance for any help :)
