Using a CustomValidator inside the EditTemplate of a FormView

Hello

I try to validate two RadComboBox's which are placed inside the EditTemplate of a FormView. The server-side validation is working fine bit the Client-side is giving me troubles.

It looks like that the RadComboBox are not yet available when the JavaScript is loaded. On this row of JavaScript:

var combo = $find("<%= rcbFuelType.ClientID %>");

I get this error message: Unknown identifier "rcbFuelType".

The FormView is part of UserContrle and I have placed the Javascript inside the asp:content tag where the FormView is. I have also tried to place it inside the EditTemplate without any result.

How can I get the this working?

Anders

<script language="javascript" type="text/javascript">

function ClientValidateFueltypes(source, arguments) {

var combo = $find("<%= rcbFuelType.ClientID %>");

var combo2 = $find("<%= rcbFuelType2.ClientID %>");

if (combo.get_value() == "N.v.t.") {

if (combo2.get_value() == "N.v.t.") {

arguments.IsValid = false;

}

</script>

Preventing Postback on Node Expand

Is there any way to prevent the postback when expanding a node? It seems like this should be unnecessary once the control is data-bound. Thanks.

RadAjaxLoadingPanel not animating in IE

RadGrid ExportToExcel to default save as xls format

Hello,

I'm looking at some code that uses the RadGrid1.MasterTableView.ExportToExcel()
type command. It sends the grid to excel just fine. However, when my client wants to save the excel file, it defaults as a web page rather than xls format. Looking at the documentation on this, my hunch is that its because the function really is sending html to excel, rather than a native xls format. Is this assumption correct?

The grid comes up in excel just as needed.
My main question is there a way to have the default excel function save the file as an xls? That is, when the user clicks "save as" in excel, it defaults to web page. I know that all the user would have to do is click file type as xls in excel. However, there are many users, and sometimes this step is overlooked which then results in a missing document in their process. If the data given to excel in a way that it would know it's "save-as" default should be xls. I didn't know if xml/csv would solve this problem or have similar side affects.

I should point out that I'm not doing much editing of the grid before sending it to the ExportToExcel(). Only setting blank columns' visual=false.

I should point out this is on IE8, and I'm coding in C#

Thanks in advance for assistance.

Combo in Grid - WHERE LIKE

Hello,

I am following this example of Combobox in Radgrid.

I am having a problem with this part of the code behind: WHERE CompanyName LIKE @CompanyName + '%'"

protected void RadComboBox1_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)

{

string sql = "SELECT [SupplierID], [CompanyName], [ContactName], [City] FROM [Suppliers]  WHERE CompanyName LIKE @CompanyName + '%'";

SqlDataAdapter adapter = new SqlDataAdapter(sql,

ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString);

adapter.SelectCommand.Parameters.AddWithValue("@CompanyName", e.Text);

I use Mysql and not Sql Server, and it seems that it does not accept + '%'"

How can I replace that to state "contains"?

Thank you

Wizard Validation not working?

Hi all,

I've been kinda pulling my hair out over this one, I'm trying to get Wizard validation working and I don't know if its just something in my project or what, but no matter what I do, they will not fire. I've gone as far as copying the example from the Wizard Validation article (http://www.telerik.com/help/aspnet-ajax/wizard-validation.html) and it still will not fire.

Am I missing something? Maybe some project level setting? Like I said, I feel like I'm taking crazy pills :P Thanks in advance!

My entire test page, the validation does not fire:
