Set the row colour dependant on checkbox column

Hi,
I am wishing to change the colour of a row if it is 'urgent' in my internal message system.
I found this code...

Protected Sub RadGrid1_ItemDataBound(ByVal sender As System.Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound

'Change the color of inactive rows

If TypeOf e.Item Is GridDataItem Then

Dim item As GridDataItem = DirectCast(e.Item, GridDataItem)

Dim Urgent As CheckBox = DirectCast(item.FindControl("Urgent"), CheckBox)

If Urgent.Checked = True Then

e.Item.BackColor = Drawing.Color.RoyalBlue

End If

End Sub

and changed it to suit my grid, or so I believed; however it does not work properly, and throws an exception ("Object reference not set to an instance of an object.") when checking whether

"If Urgent.Checked = true then"

What am I doing wrong, the code for my radgrid is...

<telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateSelectColumn="True" CellSpacing="0"

GridLines="Horizontal" AutoGenerateColumns="False" OnSelectedIndexChanged="RadGrid1_SelectedIndexChanged"

RTM-Date for SAK?

Hi,
I have tested SAK in a SharePoint 2010 environment.
Apart from the point that in a list-item edit page when using the RadEditor and inserting Images the image-editor seems to behave a bit strange (i.e. I click resize and nothing happens) and that the image-editor does not fit intor the list-item edit page popup the RadEditor is really nice.
When will SAK be RTM? I'd hate to suggest deploying CTP ;-)

Best,
Nils

Grid Advanced Databinding InPlace Edit results in No Records to Display

Good Afternoon all,

I am hoping to get some help with a simple grid setup that I am working on. I am researching how the Rad Grid control works in order to use it in our production environment. I have little knowledge of the control or its interworkings. I've read through the online documentation and have tried to recreate the example demo with focus toward how I would use it in production. I have a basic Dataset whichi I populate manually for my example. On the aspx page i'm using a basic RadGrid and set the OnNeedDatatSource, I set the MasterTableView EditMode to InPlace and have the columns auto generated. The issue i am seeing is when i click the edit button the RadGrid1_ItemCreated Event is fired but none of theobjects coming in are of type GridDataInsertItem and the IsInEditMode property is always false resulting in a grid that only display "No Records to Display". I'm not sure what i'm missing. Any help would be appreciated. My code is below:

ASPX

<%@ Page Title="Home Page" Language="vb" MasterPageFile="~/Site.Master" AutoEventWireup="false"

CodeBehind="Default.aspx.vb" Inherits="TelerikGridControlProject._Default" %>

<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>

RadListBox OnSelectedIndexChanged

When I have a RadListBox that allows multiple selections, such as:

<telerik:RadListBox ID="rlbItems" runat="server" AutoPostBack="true" Height="200px"

SelectionMode="Multiple" OnSelectedIndexChanged="items_SelectedIndexChanged" />

The server side event only fires when a single selection is made via a click. If the user clicks to drag across several items, then the event never fires. Is there another event I should be using, or another way to make this even fire appropriately when the selected items change?

Flicker problem in RADPanelBar

I am using RADPanel bar Q2 2008 in my application. I am able to successfully use the control except for a problem in animation.

The animation is showing a flicker on expand or collapse. I digged in to the issue and found that this is occuring only if i remove following string in the aspx header:

<!

DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

If the string is present, the animation works fine but my page breaks. This application is an old application and difficult to debug why it is breaking. I guess the problem is with some not well written HTML. Is there any way i can get the animation working flawlessly with the above string not present in the page?

CAPTCHA Without ASP.NET Form

I wrote a generic HTTP handler for submitting forms that is shared throughout my site like this:

<form action="formmail.ashx" method="post">

</form>

This is so the graphic artists on my team can put anything they want inside it form-wise and it doesn't rely on a form that has runat="server" in it (so no postbacks in the typical sense that we're all used to). Given that, I'm also not doing any server checking for whether the page is valid behind the button itself which is where my real question lies. Is it possible to utilize RadCaptcha in this manner and it still prevent the form from submitting? Or do I have to migrate to an ASP.NET form that can do a Page.IsValid?

Sliding Zone Width

Hi,

I would like the RadSlidingZone of my project to be invisible when a certain SlidingPane ist expanded (and regain it's visibility when that SlidingPane collapses). I've tried the following code, but it doesn't seem to work:

function OnClientDock(sender, eventArgs)

{

var slidingZone = $find("<%=RadSlidingZone1.ClientID %>");

slidingZone.Width = "0px"; ;

}

function OnClientUndock(sender, eventArgs)

{

var slidingZone = $find("<%=RadSlidingZone1.ClientID %>");

slidingZone.Width = "22px";

}
