Hi,

I have Q3 2010 asp.net ajax, i found a bug when i implement with Programmatic data (BindtoDataset)
i have all value don't have parent value match. (in french :

Cette contrainte ne peut pas être activée, car toutes les valeurs n'ont pas de valeurs parentes correspondantes.

)
My table is like as :
id    parent_id title
1     0               test1
2     0               test2
3     1               test3
4     2               test4
5     1               test5
6     2               test6

I don't understand cause if i implement with Ienumerable from my dataset it's works.

Have you an idea ?

thank's

RadAjaxManager slows down the load of a Radwindow from a user control

Hi,
In our application we got a webform with 7 tabpages (telerik:RadTabStrip -> telerik:RadMultiPage).
For each tabpage we created a usercontrol.
On one of the tabpages is a button for opening a radwindow.
At the beginning it took 3 seconds to open this window.
After installing the RadAjaxManager on the webform and the RadAjaxManagerProxy on the usercontrol-tabpage
it slows down to 9 seconds.

Between the servside eventhandler of the button-click :

protected void btnProductDataSelectRefMRDRNr_Click(object sender, EventArgs e) { RadWindowManager_ProductData.Windows[0].VisibleOnPageLoad = true; }

And the Page_load Event of the Radwindow :

<telerik:RadWindowManager ID="RadWindowManager_ProductData" runat="server"

<br>        Animation="FlyIn" VisibleStatusbar="False" Behavior="None" BorderStyle="None" KeepInScreenBounds="True" Skin="Telerik"><

br> <windows> <telerik:RadWindow ID="RadWindowselectMRDR" runat="server" ShowContentDuringLoad="false"

<br>                Width="1200px" Height="540px" Title="select MRDR" Behaviors="Close,Move" VisibleStatusbar="false"<

br> OnClientClose="OnWindowClose" Modal="True" NavigateUrl="SelectMRDR.aspx"> </telerik:RadWindow> </windows> </telerik:RadWindowManager>

It slows down from 2 to 8 seconds.

Thanks for any help,
Juergen

RadGrid in RadAjaxPanel can't be Edited?

Environment: Windows 7, Visual Studio 2008 SP1, Telerik ASP.NET AJAX 2010 Q3.
If a RadGrid Control is placed in a RadAjaxPanel, all changes to the RadGrid in DESIGN VIEW will be lost. No problem if it is out of RadAjaxPanel. Why? Excuse me, I can't search any solutions in forum or google.

Need a way to control resource header height and time column width

Hi,

Currently, I am using the scheduler to schedule appointments to resources over a 12 hour period of the day.

I would like to control the width of the time column that runs down the left hand side. Currently, I do not see any properties to control the width. The width is pretty wide, limiting precious screen real estate.

Also, I see that the rowHeight property also controls the rowHeight of the resourceHeader row. This is somewhat undesireable because I would like maximize the row heights of those rows that will have appointments displayed on them so that I can fit as much data in as possible. However, when I increase the rowHeight, it also increases the height of the resource headers, which is unnecessary. This again impacts screen real estate.

I am currently using Telerik.Web.UI v. 2008.3.1314.35

Has there been any advancements made to address these issues in newer releases or are there workarounds so help out?

Thanks!

RadEditor - Hyperlink manager customization

Hi
We are using the RadEditor as a WYSIWYG to maintain our intranet site.
Often, there is a need for us to link to pages within the intranet. Is there a way for the HyperLink Manager to "connect" to a popup or something similar where we show our sitemap and when someone clicks on one of the items on the site map, it gets sent back to the hyperlink manager ?

Gap below horizontal scrollbar on initial page load

I have a strange problem occurring on my grid.

My grid has a detailtable and expand/collapse button. It uses a setting FrozenColumnsCount="3" .
On initial load of the page, the grid shows a gap below the Horizontal scrollbar. Also, the frozen columns do not work on this initial load.
Please see attached screen shots.

I found if I removed FrozenColumnsCount="3" from the grid, the problem does not occur. This might be a coincidence though??
I also found, if I click the expand button, the problem disappears.

This might be too hard to troubleshoot what is causing this, but I need some guidance as to a 'workaround'. As I said above, the problem disappears when clicking expand. Do you know what part of the expand code is fixing this?

Some background information. My grid is underneath a table. I have some javascript that calculates the grid's splitter height based on a parent container minus the table height. This appears to work successfully, but I thought I would share this in case it could be influencing the problem.

<telerik:RadSplitter ID="RadSplitterRoadRoadwayGrid" runat="server" Width="100%" Orientation="Vertical"

BorderSize="0" VisibleDuringInit="false" OnClientLoad="setSplitterHeight">

<telerik:RadPane ID="RadPaneRoadRoadwayGrid" runat="server" Scrolling="None" BorderWidth="0"

Width="100%">

// Calculates the height of the grid on the fly.

function setSplitterHeight(splitter, arg) {

var myAjaxPanel = document.getElementById('<%= RadAjaxPanelRoadRoadway.ClientID %>');

var panelHeight = myAjaxPanel.parentNode.parentNode.clientHeight;

var myTable = document.getElementById('myTable');

var tableHeight = myTable.clientHeight;

splitter.set_height(panelHeight - tableHeight - 36);

var pane = splitter.GetPaneByIndex(0);

pane.set_height(panelHeight - tableHeight - 36);

}

I am also applying column widths at runtime. The way I am doing this is shown in the following post:
http://www.telerik.com/community/forums/aspnet-ajax/grid/how-to-set-column-width-in-code-behind-for-detailtable.aspx

Thank you for any insight into this problem!
