[Solved] RadComboBox and Required Field Validator

Hi!

I'm trying to validate the content of a Prometheus ComboBox. But I'm facing a "small" problem. This is what I have:

- A RadComboBox;
- A RequiredFieldValidator (validating the combo)
- A button

When I press the button, it postbacks to the server, and after that, it shows the warning message saying that the field is not filled.

Shouldn't the validator validate the page on the Client? Please tell me that I'm missing something... Do I have to set any other properties on the combox to get this to work?

Thanks!

postback not completed after Export to Excel

Hi,

I am trying to use Serverside ExporttoExcel() function which when executed the page doesnot complete the postback.

The download completes but the page is not completing the page lifecycle.

I have Export to Excel in a dropdownList.When that is selected the save/cancel window comes up. Even when i do either of them the dropdown would still remain on export to excel.

Any help in this matter would be appreciated.

Thanks,
Ashwini

Image at the end of textbox while typing

I'm using a SQL DataSource to bind to RadAutoCompleteBox in the Page Load. The RadAutoCompleteBox is inside a RadAjaxPanel. However, when I type anything into the box, I do not see the loading/spinning image at the end of the text box as shown in the sample here:

http://demos.telerik.com/aspnet-ajax/autocompletebox/examples/templates/defaultcs.aspx

Here's my code:

<telerik:RadAjaxPanel runat="server" ID="Panel1">

<telerik:RadAutoCompleteBox runat="server" ID="MailTo" Filter="StartsWith" DropDownHeight="400"

DropDownWidth="250" AllowCustomEntry="true" DataTextField="Text" DataValueField="Value">

<DropDownItemTemplate>

<table cellpadding="0" cellspacing="0">

<tr>

<td align="left" style="width: 50%; padding-left: 10px;">

<%# DataBinder.Eval(Container.DataItem, "Text")%>

</td>

</tr

>

protected void Page_Load(object sender, EventArgs e)
       {         
 
           MailTo.DataSource = GetUsers();        
           MailTo.DataBind();
           
       }
