Event for databinding of gridTemplate column

I want to conditionally bind the images in telerik:template column but the cs code for it never gets executed

<telerik:GridTemplateColumn ItemStyle-Width="40px" ItemStyle-Font-Names="Arial" ItemStyle-Font-Bold="true">

<ItemTemplate>

<asp:ImageButton ID="vote_up" runat="server" CommandName="up" />

<br />

<%#Eval("likes") %>

<br />

<asp:ImageButton ID="vote_down" runat="server" CommandName="down" />

</ItemTemplate>

</telerik:GridTemplateColumn>

the Cs code is

protected void answer_grid_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridTemplateColumn)

{

GridDataItem item = e.Item as GridDataItem;

ImageButton up_url = item.FindControl("vote_up") as ImageButton;

ImageButton down_url = item.FindControl("vote_down") as ImageButton;

if (Eval("expr1").ToString().Equals(cur_mem_id))

{

if (Eval("liked").ToString().Equals("TRUE"))

up_url.ImageUrl = "~/images/up_no";

}

else up_url.ImageUrl = "~/images/up_logo.png";

if (Eval("expr1").ToString().Equals(cur_mem_id))

{

if (Eval("liked").ToString().Equals("FALSE"))

down_url.ImageUrl = "~/images/down_no.png";

}

else down_url.ImageUrl = "~/images/down_logo.png";

}

the code in If block never gets executed

When will IE6 support go away?

With the latest quarterly release of ASP.NET Ajax, Telerik dropped support for ASP.NET 2.0. We'd like to understand ahead of time what Telerik's plans are for continued support for IE6? We'd all love it if corporate users would finally ditch a 9-year-old browser, but users are users.... So, in short, when will Telerik stop supporting IE6 with their new releases?

Thanks,

- Mike Oliver

Trying to locate skin css files from msi install

RadAjaxManager in User Controls

I have a page that has several user controls in it. The page inherits from a master page, and that master page has a single RadAjaxManager control on it. Every user control has a RadAjaxManagerProxy that handles ajaxing just the child controls contained inside that user control. Everything is functional, but there is some behavior I didn't expect.

For example, like I said above, User Control 1 has it's own RadAjaxManagerProxy on it that ajaxifies a RadButton to a RadGrid. When the button is clicked in User Control 1, the RadGrid is updated as expected; however, User Control 2 is also updated (another user control on the same page with it's own RadAjaxManagerProxy). Is that behavior expected? I thought if a button was ajaxified, only the controls specified would be updated when an ajax request was initiated? So why is User Control 2 updated as well? Am I misunderstanding the functionality?

Error displaying InsertItem

I had this Error
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
when i tried to add new record.

Update work fine with RadInputManager to validate the textbox/NumuricTextbox.
I think it might be my js conditionalPostback and validateRadUpload for disable ajax to update Image from RadUpload

if (eventArgs.get_eventTarget().match(theRegexp)) {

var upload = $find(window['UploadId']);

//AJAX is disabled only if file is selected for upload

try{

if (upload.getFileInputs()[0].value != "") {

eventArgs.set_enableAjax(false);

}

}catch(Error){

}

function validateRadUpload(source, e) {

e.IsValid = false;

var upload = $find(source.parentNode.getElementsByTagName('div')[0].id);

var inputs = upload.getFileInputs();

for (var i = 0; i < inputs.length; i++) {

//check for empty string or invalid extension

if (inputs[i].value != "" && upload.isExtensionValid(inputs[i].value)) {

RadDock as Detail viewer

Hi,

I've been looking for a way to get a view button on a grid to open a raddock for the current row and present read only data for it - kind of the view mode to look like the edit mode with a popup form. I think that the raddock will look closer to the popup form than a radwindow.

Now one way that I could acheive this is to open a new page inside the dock or even just call some server side code to populate labels containing the view data.

There must be a better way though that can work more seamlessly with the RadGrid. Has anyone done this before or know of any good examples on the site (I may have missed some).

Thanks in advance for any pointers.

Regards,

Jon
