PropertyName="SelectedValue"

Type="Decimal" />

</SelectParameters>

</asp:SqlDataSource>

I would prefer to keep all markup in aspx as opposed to changing the line colors in the code behind if that is possible.

The attached shows the chart w/ the default colors and cannot seem to change.

Thanks,

Steve

"word-wrap:break-word" does'n work at ExportToPDF

Hi
My problem with ExportToPDF is that columns is being overlapped when not wide enough to display text.
So I'm trying to use "word-wrap:break-word". It works fine at grid control and IE displays all of text.
But It doesn't work if it is exported to a PDF. It doesn't break word at all in pdf output.
In PDF output, is there any way to display all text by extending height of row?
I don't want text to be truncated.

Thanks

Label Text inside CommandItemTemplate not visible in after i click Delete

Dear Sir/Madam

I'm Maha From India.

Advance Thank you for Helping me

I have RadGrid1(using Mutiselect checkbox option) in my project

Problem : Label Text inside CommandItemTemplate not visible in after i click Delete(LinkButton1)
==================================================================
Inside CommandItemTemplate I have Label(lblmsg) to display some message to user for validation and DB Deleted Message

If user clicking LinkButton(LinkButton1) without seelcting any checkbox means I write validation

That validation message will display on this lblmsg correctly

But if user select the check box and then click Delete means I want to show Confirmation message to user

Message format : Customer ID1,Customer ID2 deleted from DB succesfully

The above message will not visible in RadGrid

But If i debug means Thats Label Text Properly assigned using C#(RadGrid1_ItemCommand)

Note:
====
After execution of RadGrid1_ItemCommand() ->RadGrid1_NeedDataSource() method invoked Automatically

So My Doubt is whether RadGrid Reassign my Label Text as Empty.

Becoz in Browser View Source 

Inside span my Text is not there

RadTimePicker control not showing popup of times

I am trying to use the RadTimePicker on several web pages. I've kept it pretty simple at first and put the following telerik-specific code on a page:

first, at the top of the page is this:

%@ Control Language="c#" AutoEventWireup="false" Codebehind="service_category_admin.ascx.cs" Inherits="vtvn_service.service_category_admin" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
<%@ Register tagprefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI" %>

then in the body is this:
<telerik:RadTimePicker ID="start_time_picker" visible="true" ZIndex="30001" runat="server">
</telerik:RadTimePicker>

One one page, it works...sometimes. That is, if I click on the clock icon, a popup with times to select from appears.

On a couple other pages that I put the code on, clicking the clock icon does nothing, except generate the following javascript errror:

Webpage error details
User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET4.0C; .NET4.0E; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)
Timestamp: Thu, 23 Aug 2012 18:28:49 UTC

Message: Object doesn't support this property or method
Line: 179
Char: 3
Code: 0
URI: http://aspnet-scripts.telerikstatic.com/ajaxz/2012.1.411/Calendar/RadCalendarCommonScript.js

I am running version 2012.1.411.40 of the tererik.web.ui dll.

Any and all help will be appreciated as I am pretty much dead in the water right now.

Nested RadGrid occasionally displays blank row

Hi,

We have a grid that contains nested rows three levels deep, in the following way:
1. Status
2. -- Action
3. -- Role

To add a Role, there is an 'Add Row' button, which contains a dropdown of Roles on a GridDropDownColumn. There is an Insert button and a Close button. This functionality works fine to add a Role, but sometimes the Role name is blank in the row below. It seems to only happen after deleting/inserting roles, particularly if a higher up row is expanded as well.

I'm unable to reproduce the exact steps as it is intermittent, but I was wondering if there are any known issues with nested rows in grids, or if you have any suggestions in how to establish the cause of this?

Regards,
Graeme

I follow the sample in http://www.telerik.com/help/aspnet-ajax/grid-set-focus-on-textboxes-in-edit-control.html to set one of the textbox focus when itemcreated. However, I found that this the script did not work when I set AllowKeyboardNavigation = true in client setting. If I set AllowKeyboardNavigation = false, the textbox can get the foucs when I edit the row.

Below is my coding in setting the textbox focus on ItemCreated event.

If e.Item.IsInEditMode Then

If TypeOf (e.Item) Is GridEditFormInsertItem Then

ControlToFocus = DirectCast(DirectCast(e.Item, GridEditableItem).FindControl("txtOrgCode"), TextBox)

Else

' Dim lGridEditableItem As GridEditableItem = DirectCast(e.Item, GridEditableItem)

ControlToFocus = DirectCast(DirectCast(e.Item, GridEditableItem).FindControl("txtOrgName"), TextBox)

End If

If Not ControlToFocus Is Nothing Then

Dim script As String = [String].Format("$get('{0}').focus(); $get('{0}').select();", ControlToFocus.ClientID)

RadScriptManager.RegisterStartupScript(Page, GetType(Page), "EditFocusScript", script, True)

End If

Thanks!

When I use realFontSize, RadEditor does not inherit font size of style

Hi,

We are using the Real Font Sizes for the RadEditor.
When I create new line, RadEditor does not inherit font size to the line.

1. All clear
2. Input any string and set any font size.
3. move cursor to end of the string.
4. Input enter key.

Result:
testtesttest

Expected Result:
testtesttest
 

If I use the Default Font Size instead of the Real Font Size, the behavior is expected.

Please tell me any workarounds.
Thanks,
Akinori
