Very slow DetailTableDataBind

I'm using RadGrid in a ascx control as presented below. I'm having problem with performance with Detail tables. Sometimes there more than one detail table attached to master table row and when I'm expanding hierarchy function Radgrid_DetailTableDataBind2 is called n-times (n detail tables). The worst thing is that between second and third (when there is 3 detail tables) call there is sometimes 10 second delay. Is there some way to improve performance ?

In first approach there was :

Radgrid.MasterTableView.HierarchyLoadMode = GridChildLoadMode.Client;

Radgrid.ClientSettings.ClientEvents.OnHierarchyExpanded = "OnHierarchyExpanded";

Radgrid.ClientSettings.ClientEvents.OnHierarchyCollapsed = "OnHierarchyCollapsed";

but function Radgrid_DetailTableDataBind2 on initialization was called n * Row (n - numer of detail tables, Row - visible rows on page), which was on 10 visible rows was even 40 times.

I'm attaching most important function. IntializeGrid() is called in protected void Page_Init(object sender, EventArgs e).

IntializeGrid()

{

            Radgrid = new RadGrid();



            Radgrid.ItemEvent += new GridItemEventHandler(Radgrid_ItemEvent);

Radgrid.Init += new EventHandler(Radgrid_Init);

Radgrid.NeedDataSource += new GridNeedDataSourceEventHandler(Radgrid_NeedDataSource);

Radgrid.PreRender += new EventHandler(Radgrid_PreRender);

Radgrid.DetailTableDataBind += new GridDetailTableDataBindEventHandler(Radgrid_DetailTableDataBind2);

Radgrid.MasterTableView.HierarchyLoadMode = GridChildLoadMode.ServerOnDemand;

...

}

protected void Radgrid_Init(object sender, EventArgs e)

{

Radgrid.ItemCommand += new GridCommandEventHandler(Radgrid_ItemCommand);

Radgrid.MasterTableView.DetailTables.Clear();

ArrayList Cols = (Session[IdOkna + this.ID + "MultiLayerMainCols"] as ArrayList);

for (int i = 0; i < Cols.Count; i++)

{

GridTableView tableViewLevel = new GridTableView(Radgrid);

tableViewLevel.HierarchyLoadMode = GridChildLoadMode.ServerOnDemand;

tableViewLevel.AutoGenerateColumns = false;

string TableName = Cols[i].ToString();

try

{

MainCol = ((XmlDocument)Session[IdOkna + this.ID + "XML_Doc"]).SelectSingleNode("//columns/child::column[source='" + TableName + "']").SelectSingleNode("columns/child::column[editSync='s']").SelectSingleNode("source").InnerText;

XmlNode xg = (SubColumns[MainCol + "." + TableName] as XmlNode);

loadsubcolumns(tableViewLevel, xg);

}

catch

{

loadSameColumns(tableViewLevel);

}

Radgrid.MasterTableView.DetailTables.Add(tableViewLevel);

If there's missing some code please give me a hint which function...
Thank you in advance

slow performance typing in RadTextBox

Hi,

With the latest version of the controls (2011.2.712.40) I am experiencing a rather unusably slow typing response in one of my RadTextBoxes. It is a multiline textbox, wtih a maxlength setting. I am trying to get a test case together as this is a definite issue since changing from the Q1 2011 version of the controls, but it seems to only happen in very particular circumstances.

Before I burn a lot of time trying to get a test case, has anyone else seen this issue?

Thanks.

Upgrade Wizard Errors

I just finished downloading and installing RadControls for ASP.NET AJAX Q1 2013 using your downloader. After successful completion, I ran the Upgrade Wizard in one of my VS2012 projects and now the solution (which was working perfectly) will not even execute.

Why do we have to go through this with your products on every release? Do you have a correction procedure identified for how I get this critical project running again?

The first error encountered involved the menus, but that will only be the first. I use many of the controls in this project. A screen capture of the yellow screen of death is attached.

Any words of wisdom? Thanks in advance!

raddock Title background color

I'm trying to set a radDock Title's background color in a user control dynamically in code-behind.
I can set the dock's background but Im not sure how to access just the title bar

The one thing I've found that works is some css I've placed on the control
<style type="text/css">
.rdTitleBar
{
background-color: pink;
}
</style>

however this changes all the radDocks on the page and is not dynamic.
so Is there a way to access in codebehind dock title background dynamically.

Maintain the scroll position on page reload

Hi,

I am working on an ASP.Net website which is using the latest Telerik version Q3 2012 for Rad Ajax Controls. There are certain pages in my website which consist of 10-12 Rad Editors (each consisting of individual edit,save and review buttons). The issue is that suppose, I scroll down to any of the below editors on the page and then try to edit or save or any other function, the page reloads and takes me back to the top of the page. It causes a lot of trouble to scroll down again as well as create confusions in editing and saving.

The Rad Ajax Panel contains the Editor and each of the controls like edit,save, etc are on a user control common to all pages.

I tried using MaintainScrollPositionOnPostBack = true on individual pages, web.config and code behind but nothing helps.

Please suggest me some way to maintain the scroll position on the editor which is being modified or used.

Thanks,

Manisha
