3 step panelbar with validaton, postback issues

Hi,

I have a RadPanel that has 3 radpanelitems, and for each of these panelitems i have a validation group that checks if all inputs on each panelitem is correct, if they are i want the user to hit a Next button that does the validation, so far all good.

If the validation goes trough in the first panelitem it does a postback and all values is lost, i only want it to validate and then enable and expand the second panelitem clientside, is this possible?

ClientScripts when Silverlight enabled.

<script type="text/javascript">

//<![CDATA[

function mergeFileUploaded(sender, args) {

<%= Page.GetPostBackEventReference(LB_doUploadData)%>;

}

function mergeUplOK(sender, eventArgs) {

$telerik.$(".mergeuplErr")

.html('');

}

function mergeValidationFailed(sender, eventArgs) {

$telerik.$(".mergeuplErr")

.html('<%= GetTranslation("invalidmergefile") %>');

sender.deleteFileInputAt(0);

}

//]]>

</script>

<telerik:RadAsyncUpload ID="RadAsyncUpload_Data" HttpHandlerUrl="~/uploadHandler.ashx"

runat="server" MaxFileInputsCount="1" AllowedFileExtensions="csv,xls,xlsx,tsv"

OnClientFilesUploaded="mergeFileUploaded" OnClientFileUploading="mergeUplOK" OnClientValidationFailed="mergeValidationFailed" />

<div id="uplErr" class="mergeuplErr"></div>

When Silverlight is enabled and both OnClientValidationFailed and OnClientFilesUploaded are defined it seems that it fires the OnClientFilesUploaded even when the Validation failed. When Flash it works as expected. Have I missed anything?

RadGrid not showing inserted rows

Dear forum users

I'm fairly new to the RadControls but I'm learning fast. I've created a rather simple form application which retrieves data from a SQL source and displays this data in a RadGrid. Unfortunately I'm running into following problem: when I try to insert a new row into the gridview using InsertItem this row is not showing up in the gridview. I hope you will be able to help me. Just some background info:

- The RadGrid uses the NeedDataSource event
- See the screen cap for more info

Thanks in advance!

PS: The two rows displayed in the screen cap are comming from the SQL source. I however removed the data because of privacy issues.

Client Databind Fails/Hangs with DataFormatString {0:g}

I have a RadGrid where one of the columns binds to a date/time value. I use a GirdDataBound column and it binds correctly on the server. Using the same source for the data, this fails when I try to bind on the client. It shows the first record, then just stops. The lines that follow in the Javascript function do not execute.

I removed the DataFormatString and it worked.

To work around this, I changed the column to a string and formatted it before sending it out to be bound.

I know I'll trip on this again some day (probably soon), so I'd like to get a resolution.

Thanks.
