RadComboBox OnItemRequested

I am getting an error 'Cannot create an object of type 'Telerik.Web.UI.RadComboBoxItemsRequestedEventHandler' from its string representation 'rcbPersonGroupSelector_ItemsRequested' for the 'OnItemsRequested' property.' on the Rad combo box.

This is the code used :

Prevent Detail table from expanding

I have a grid which uses grouping on the top-level table and also has a detail table. it seems that, when a group is collapsed, and then expanded, then the detail table is expanded for all items in the group. Is there a way to prevent the detail table from being expanded when the user expands a group? The detail table should only be expanded when the user clicks on the expand/collapse column for the item in the master table.

GetDataKeyValue returning first Value in Grid

Hi,

I have a couple Grids on my page which include a "Download" GridButtonColumn that has AJAX disabled via Javascript to enable a File Download. When clicking these download buttons, the Code behind uses GetDataKeyValue to get the ID of the row:

protected void CompleteTickets_ItemCommand(object sender, GridCommandEventArgs e)

{

if (e.CommandName == "Refresh")

{

CompleteTicketsGrid.Rebind();

}

if (e.CommandName == "Download")

{

// Get Ticket ID

GridDataItem item = (GridDataItem)e.Item;

int ticketID = Convert.ToInt32(item.GetDataKeyValue("TicketID"));

// Use Ticket ID to Get File from File Repository

}

However, this code works for all of my other functions (edit), but on the "Download" button it automatically pulls the TicketID from the first Row of the Grid. It doesn't matter if I delete rows or change pages on the Grid, the GetDataKeyValue method always pulls the first item's ID rather than the row I've clicked.

I have DataKeyNames="TicketID" set in the MasterTableView of the Grid, and the Grid is populated with a LINQ/IQueryable Datasource.

I've also attempted to create a work-around for this problem by using this code instead, considering I have a column which displays the TicketID:

int ticketID = Convert.ToInt32(item["TicketID"].Text);

But to no avail, it is still grabbing the first Row's "TicketID". When constructing the GridDataItem item object, it's almost as if it's automatically grabbing the wrong Row from the very beginning. I've included an image of what exactly is happening.

Here is also the block of ASPX code of my Grid.

<telerik:RadGrid

<telerik:GridButtonColumn UniqueName="LoadTicket" ButtonType="LinkButton" Text="Load Ticket" CommandName="LoadTicket" ItemStyle-Width="13%" HeaderStyle-Width="13%"/>

</Columns>

</MasterTableView>

<ItemStyle Height="40" VerticalAlign="Middle"/>

<AlternatingItemStyle Height="40" BackColor="CadetBlue" ForeColor="White" VerticalAlign="Middle" />

<ClientSettings>

<ClientEvents OnCommand="OnGridCommand" />

<Scrolling AllowScroll="False" UseStaticHeaders="True" />

</ClientSettings>

</telerik:RadGrid>

Oh, and here's the JavaScript I'm using to Disable AJAX on the Download Button:

// Disables Ajax on Buttons Clicked in Grid

//

function OnGridCommand(sender, args) {

var itemArgument = args.get_commandArgument();

var itemCommand = args.get_commandName();

if (itemArgument == "DisableAjax" || itemCommand == "Download") {

window["disableAjax"] = true;

}

else {

window["disableAjax"] = false;

}

args.set_cancel(false);

}

Any ideas are greatly appreciated, as I've hit a brick wall with this one... Or maybe I've just got tunnel vision from staring at this for so long.

Best Regards,

Landon

Problem with centralized error handling, Application_Error

Hi,

We have done the following:
In Appliction_Error and in ScriptManager_AsyncPostBackError, we handle and logs the exception.
Then we redirect to an error page.

When not using radcompression, this works for all cases, but when using radcompression, the redirect doesn't happen when an exception occurs in Page_PreInit. The exception must also be in an Async callback, normal postbacks works as expected.

Default.aspx:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="default.aspx.vb" Inherits="WebApplication8._default" %>

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

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<div>

<asp:ScriptManager ID="sm" runat="server"></asp:ScriptManager>

<asp:UpdatePanel ID="upError" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">

<ContentTemplate>

<asp:Button ID="btnError" runat="server" Text="Error" />

</ContentTemplate>

</asp:UpdatePanel>

<asp:Button ID="btnErrorNoUpdatePanel" runat="server" Text="ErrorNoUpdatePanel" />

</div>

</form>

</body>

</html>

Default.aspx.vb:

Public Class _default

Inherits System.Web.UI.Page

Private Sub _default_PreInit(sender As Object, e As System.EventArgs) Handles Me.PreInit

If Me.IsPostBack Then

Throw New Exception("Test")

End If

End Sub

Private Sub sm_AsyncPostBackError(sender As Object, e As System.Web.UI.AsyncPostBackErrorEventArgs) Handles sm.AsyncPostBackError

Server.ClearError()

Response.Redirect("Error.aspx")

End Sub

End Class

Error.aspx:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Error.aspx.vb" Inherits="WebApplication8._Error" %>

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

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<div>

An error occured!

</div>

</form>

</body>

</html>

web.config:

<?xml version="1.0"?>

<configuration>

<system.web>

<customErrors mode="Off"/>

<compilation debug="true" strict="false" explicit="true" targetFramework="4.0" />

<httpModules>

<add name="RadCompression" type="Telerik.Web.UI.RadCompression"/>

</httpModules>

</system.web>

<system.webServer>

<modules runAllManagedModulesForAllRequests="true">

<remove name="RadCompression" />

<add name="RadCompression" preCondition="managedHandler" type="Telerik.Web.UI.RadCompression"/>

</modules>

</system.webServer>

</configuration>

Global.asax.vb:

Imports System.Web.SessionState

Public Class Global_asax

Inherits System.Web.HttpApplication

Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)

' Fires when an error occurs

Server.ClearError()

Response.Redirect("Error.aspx")

End Sub

End Class

When hitting the Error-button, I don't get to the error page, but when hitting the ErrorNoUpdatePanel I do get to the error page.
If turning off RadCompression both cases works.

Regards
Caesar

Show detailtable next to mastertable row (IE8)

I have a grid which uses nested view templates like this http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplate/defaultcs.aspx i'm using templates in both the master and detail.

According to my requirements the detail view should appear next to the master. When the grid renders there is 1 tr for the master row and another tr for the detail row. As far as i know there is no way to show tr next to each other in IE8

I've auto expanded the grid by default and hidden the expand columns. Basically the layout of what i'm looking for is like this:
parent1 | parent1_child1
| parent1_child2
parent2 | parent2_child1
| parent2_child2

Any help will be greatly appreciated!
