Conditionally supress the background image in the Black skin

I've got a control based on the RadTextbox.

My control has a IsMandatory property and I'm doing something like this in the control...

protected override void OnPreRender(EventArgs e)

{

base.OnPreRender(e);

if (isMandatory)

{

RadTextBox1.EnabledStyle.BackColor = System.Drawing.Color.Pink;

}

This works a treat.

Except when the skin is Black. The black skin renders an image in the background of the textbox.

I need to supress this when my input control has IsMandatory = true

getDataKeyValue for Parent Grid

In JavaScript, if I have a handler for the double click event of a row (for example), and that event fires on a row in a detail table, how would I access the client data key of the parent row? So something like this:

function RowDoubleClick(sender, eventArgs) {

var tableName = eventArgs.get_tableView().get_name();

if (tableName == "Master") {

var masterRowId = eventArgs.getDataKeyValue("Id");

}

else {

var detailRowId = eventArgs.getDataKeyValue("Id");

var parentRowId = // This needs to be the key associated with the detail table from the parent table.

}

Width in Firefox 8

Hi

I am having a nightmare with a combobox width in Firefox (all versions) but not in IE7/8/9, Chrome, or Opera.
Attached are 2 images showing the problems, here is the code:

<%

@ Control Language="C#" AutoEventWireup="true" CodeBehind="TelerikTradeSelectionControl.ascx.cs" Inherits="GalileoAdmin.Resources.Controls.Tradesman.TelerikTradeSelectionControl" %>

<%

@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<%

--<telerik:RadFormDecorator ID="FormDecorator1" runat="server" DecoratedControls="all" Skin="Web20"></telerik:RadFormDecorator>--%>

<

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

<span class="redtext">*</span> Your MAIN trade</label>

 </div>

<telerik:RadComboBox ID="cmbMainTrade" Width="242px" runat="server" Filter="Contains" Skin="WebBlue" AutoPostBack="True" CssClass="qqdd"

OnSelectedIndexChanged="cmbMainTrade_SelectedIndexChanged" DropDownWidth="242px" style="padding-bottom:7px;" >

</telerik:RadComboBox>

</div>

Additional trade (if needed)

</label>

 </div>

<telerik:RadComboBox ID="cmbSecondaryTrade" Width="242px" AllowCustomText="true" EmptyMessage="Select a Trade" runat="server"

Filter="Contains" Skin="WebBlue" AutoPostBack="True" OnSelectedIndexChanged="cmbSecondaryTrade_SelectedIndexChanged">

</telerik:RadComboBox>

</ContentTemplate>

</

asp:UpdatePanel>
and

private void BindPrimaryTradeSelection()

{

//bind the combobox

cmbMainTrade.DataSource = GetTrades(

true);

cmbMainTrade.DataTextField =

"Name";

cmbMainTrade.DataValueField =

"Name";

cmbMainTrade.DataBind();

if (cmbMainTrade.Text == String.Empty)

{

RadComboBoxItem item = new RadComboBoxItem();

item.Text =

"Click to select a trade";

item.Value =

"";

item.Selected =

true;

item.Enabled =

false;

item.Visible =

false;

cmbMainTrade.Items.Add(item);

}

private void BindSecondaryTradeSelection()

{

//bind the combo box

cmbSecondaryTrade.DataSource = GetTrades(

false);

cmbSecondaryTrade.DataTextField =

"Name";

cmbSecondaryTrade.DataValueField =

"Name";

cmbSecondaryTrade.DataBind();

if (cmbSecondaryTrade.Text == String.Empty)

{

RadComboBoxItem item = new RadComboBoxItem();

item.Text =

"Click to select a trade";

item.Value =

"";

item.Selected =

true;

item.Enabled =

false;

item.Visible =

false;

cmbSecondaryTrade.Items.Add(item);

}

The other dropdowns on the page are standard HTML dropdowns.
Please point me in the right direction
Thanks
Dave

Open a RadWindow in an async postback?

Not sure what I'm doing wrong. I have an operation (initiated from a GridButtonItem click) that occurs inside an async postback. Depending on the results of the operation I need to update image and label controls hosted in a RadWindow, display the RadWindow, wait for the user to click a button, determine the button that was clicked and continue with the operation.

For the life of me I can't get the RadWindow to open with generating an exception. I've stripped out the RadGrid and simplified the code to try to find the problem but alas, no joy.

My aspx looks like this:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="ZZRadWindow.aspx.cs" Inherits="SitefinityWebApp.ZZRadWindow" %>

<!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>

<script>

function OpenWindow()

{

var wndMgr = GetRadWindowManager();

wndMgr.open("", "ConfirmPlaybackWindow");

return false;

}

</script>

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

<div>

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

<asp:UpdatePanel ID="WindowUpdatePnl" runat="server">

<ContentTemplate>

<asp:Label ID="msgLbl" runat="server" />

<telerik:RadWindowManager ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false" ReloadOnShow="true" runat="server" Skin="Forest" EnableShadow="true" Font-Bold="False" Modal="True">

<Windows>

<telerik:RadWindow ID="ConfirmPlaybackWindow" runat="server" DestroyOnClose="False" Skin="Forest" Modal="True">

<ContentTemplate>

<div class="confirmationDlgWrp">

<div class="alertWrp">

<asp:Image ID="AlertImg" runat="server" CssClass="dlgIcon" />

<asp:Label ID="AlertLbl" runat="server" CssClass="dlgLabel" Text="Hello World" />

</div>

<div class="confirmationDlgBtnWrp">

<asp:Button ID="YesBtn" runat="server" CssClass="dlgYesBtn" Text="Yes" />

<asp:Button ID="NoBtn" runat="server" CssClass="dlgNoBtn" Text="No" />

</div>

</ContentTemplate>

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

<asp:Button ID="PostBackButton" runat="server" Text="Do Postback" />

</ContentTemplate>

</asp:UpdatePanel>

<p />

<asp:Button ID="Button1" runat="server" OnClientClick="return OpenWindow()" Text="Open RadWindow" />

</div>

</form>

</body>

</html>

And my codebehind looks like this:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

namespace SitefinityWebApp

{

public partial class ZZRadWindow : System.Web.UI.Page

{

private static int PostBackCount = 0;

protected void Page_Load(object sender, EventArgs e)

{

if (IsPostBack)

{

msgLbl.Text = string.Format("{0}<p/>PostBackCount: {1}", msgLbl.Text, ++PostBackCount);

string script2 = "<script type=\"text/javascript\">OpenWindow();</script>";

ScriptManager.RegisterStartupScript(WindowUpdatePnl, typeof(string), "OpenWindow", script2, false);

}

Clicking the button located outside the UpdatePanel result in the RadWindow displaying without error. Clicking the postback button located inside the UpdatePanel results in the following exception:

Microsoft JScript runtime error: Sys.InvalidOperationException: Can't be called after dispose

Any idea what I'm doing wrong here?

Thanks -- Steve

Getting frustrated - 2 errors that keep popping up!

Alright...every time I drag an "old" telerik control that uses version 2009.3.1314.20 of the .dll, it overwrites the newer version of 2009.3.1314.35. As a result, it gives me the following error:

"Could not load file or assembly "Telerik.Web.UI, Version=2009.3.1314.35...or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)"

I have tried for two days to figure out how to fix this, or to stop this incessant overwriting, but I have been unable to do so. Worse still, I am now at least 2 days behind on my project, and my supervisors are wondering if we shouldn't just go back to the 'old' tools we had instead of using Telerik, because this looks like (at least, it does to them) that Telerik has some serious stability issues to address. I can't say I disagree....

The second problem is an error that says:

"Cannot create an object of type 'System.String[]' from its string representation 'KeyField' for the 'DataKeyNames' property."

This error is especially infuriating because I have the EXACT SAME CODE on another page....and it WORKS! I have no idea what the problem is, or how to fix this. Attached is a screenshot (cropped) of the errors in question. I really need some help here before I throw my monitor out the nearest window!

The length of the string exceeds the value set on maxJsonLength property

There is a known problem with maxJsonLength property:

http://support.microsoft.com/kb/981884

However, this hotfix did not work. Maybe because it is for the MS UpdatePanel?

If so, how can this be resolved? This error comes up when grid tries to pull too many rows.

Dynamically change FormTemplate in EditFormSettings

I am having problem to display the contents within the form template. I have the following in my rad grid :-

<EditFormSettings EditFormType="Template">
                <FormTemplate>
                    <table id="1" width="100%" border="0" cellpadding="0" cellspacing="10">
                        <tr>
                            <td colspan="3">
                                <span class="des"><asp:Label ID="lblDestination" runat="server" Text='<%# Eval("Destination") %>' /></span>
                            </td>
                        </tr>
..

and I would like to hide the table row based on the DataTable binding. May I know is there any good way of doing this?
