Cascading ComboBoxes causes radGrid to reBind

I'm having a logic issue. I have some Comboboxes that I need to cascade while in Edit or Insert Mode. The problem is when I Bind the second Combo based on the first, the entire Grid does a PostBack and so the Combos rebind again.

I know i'm likely just missing an 'If Postback' or something, but my brain is mush right now.

<telerik:RadGrid ID="RecipientsGrid" runat="server" AutoGenerateColumns="false" EnableViewState="true" PageSize="5" AllowFilteringByColumn="true" AllowPaging="true" AllowSorting="True">

<telerik:RadComboBox ID="CountryCombo" runat="server">

get radgrid index after set_enable false ajax

I used radgrid view for display some of my data and using that rad view. I need to do two things
1. delete some records - need ajax manager
2. stream to web browser - need to disable ajax manager.

here is my code snipts

<script type="text/javascript">
function requestStart(sender, args) {
if (args.get_eventTarget().indexOf("GD") > 0)
args.set_enableAjax(false);
}
</script>
<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" ClientEvents-OnRequestStart="requestStart">

in the grid

<%--<telerik:GridButtonColumn ButtonType="LinkButton" Text="<img src='../App_Themes/default/images/genDoc.gif' border='0' title='Generate Document'/>" UniqueName="GD" CommandName="G"></telerik:GridButtonColumn>--%>

<telerik:GridTemplateColumn HeaderText="" UniqueName="Image">

<ItemTemplate

<asp:ImageButton ID="GD" runat="server" ImageUrl="~/App_Themes/Default/images/genDoc.gif" CommandName="1" OnClick="ImageButton1_Click"

>

</

asp:ImageButton>

</

ItemTemplate><br></telerik:GridTemplateColumn>

in the code behind

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
{
if (e.CommandName == "G")
{
genDoc(e.Item.ItemIndex);
}
}

protected void ImageButton1_Click(object sender, EventArgs e) //method 2
{
genDoc(0);
}

If I use the commented link button thing it will go to the method run method well but not give me download a file.
If I use image button it works well and I can download a file, but I cant get particular index to my method(e.Item.ItemIndex
)...{in the genDoc() - document.Save("Sample.doc", FormatType.Doc, Response, HttpContentDisposition.Attachment); }

any way what I want to pass e.Item.ItemIndex value to my method genDoc(int index)...Please help me. thanks

Get column names with Javascript

I'm having a hard time getting all of the column names for a tree list with javascript

I can call get_columns() and get an array of objects back, but they don't seem TreeListColumn objects - I can't call get_uniqueName() on them. I've dug around in the objects a bit in the debugger and I don't see the unique name in there at all.

Am I doing something wrong?

Scheduler WebService winforms

Hello

I am considering such scenario - one web service for appointments and multi-client schedulers.
I have created asp.net page with radscheduler and webservice binding.
Now I am trying to use this web service for winforms scheduler (I am performing some operations in web service so solution with direct db access is unacceptable for me and I would like to have everything in one piece, in web service).
So I am trying to get appointments from this web service - unfortunately it is JSON service so it is not so easy..
I can't deserialize such method in forms client

public List<AppointmentData> GetJSONScheduler(SchedulerInfo schedulerInfo)

I am suceesfully invoke this method (but I have to make some modifications in JSON string before send it) and I can't deserialize return List
I have been trying:

DataContractJsonSerializer dJSON = new DataContractJsonSerializer(typeof(List<AppointmentData>);

List<AppointmentData> sr = (List<AppointmentData>)dJSON.ReadObject(str);

//str is response from HttpWebResponse

JavaScriptSerializer jscriptDeserializer = new JavaScriptSerializer();

jscriptDeserializer.RecursionLimit = 100;

List<AppointmentData> srResult = jscriptDeserializer.Deserialize<List<AppointmentData>>(sbResponse.ToString());

//sbResponse is StringBuilder made from GetResponseStream() of HttpWebResponse

Do you have any advices?

Thanks in advance
Regards

2012_3_1016 Installation Kills Visual Studio Projects On Load

After installing your latest version of Telerik Rad Ajax Controls RadControlsForAspNetAjaxControlPanel_2012_3_1016.exe (and no other upgrades to the other products)...
When I open an existing project that uses Telerik in Visual Studio 2010, it immediately gives the error that Visual Studio has stopped working and kicks me out.

However, if I open Visual Studio without an existing project, it opens fine.

This occurred right after installing your project and having done nothing else and happens to all 4 of my projects that use Telerik.

Ack!

Please help. How do I back out and get the previous version?

thanks.
