I have a datatable that have 500 rows. And I assign it to the Radgrid by
"rgAdvSearch.DataSource = dtData" at page_load. My Radgrid don't have paging, but it takes over a minutes to finish loading. When I enable the paging of the Radgrid, it take only few seconds to get it done. I want to know how can it be faster if I don't want paging. Thanks.

Integrating Radcontrols in MOSS

I like to start using Rad controls for ASP.NET AJAX in MOSS 2007 but when I enable the controls in the masterpage on the root site I got the following error:

An error occurred during the processing of /_catalogs/masterpage/default.master. Could not load file or assembly 'Telerik.Web.UI, Version=2008.1.512.20, Culture=neutral, PublicKeyToken=121fae78165ba3d4' or one of its dependencies. The system cannot find the file specified.

The web.config has all necessary entries and I was making sure I registered both libraries as follows:

gacutil -i c:\Telerik\Telerik.Web.UI.dll
gacutil -i c:\Telerik\Telerik.Charting.dll

Any ideas I will really appreciate.

Editing source code

Hi,

I'm currently using a standard TextBox for entering C# source code. I'm thinking of switching to RadEditor and would like to know if I can;

1) showing the current line number for the caret
2) only use plain c# text in the editor

Thanks

[Solved] ierror n ItemDataBound: Unable to cast object of type 'Telerik.WebControls.GridInsertionObject' to type

Hi,

While trying to Insert a row to my grid...(after a successful load and the same code already executed)
In my grids ItemDataBound event, I get the following error:
Unable to cast object of type 'Telerik.WebControls.GridInsertionObject' to type

I use the underlying datasource to retrieve the value for a checkbox and set it T or F.

The code in it
Whilst doing the following...

if (e.Item is GridDataItem && e.Item is GridEditableItem)

{

GridDataItem item = e.Item as GridDataItem;

CheckBox box = (CheckBox)item.FindControl("chkLstAdd");

Planning.

Task dataSourceRow = (Planning.Task)e.Item.DataItem;

//set custom attributes (i.e the checkbox.checked value) from the datasource:

box.Checked =

false;

if (dataSourceRow.IsTaskAllocated.ToString() == "True")

{

box.Checked =

true;

}

}

Should I not try prevent the "To be inserted row " from executing this code, ? if so How?

ManyThanks
Neal

Not switches to the next tab When Next button is clicked

Hi Telerik

I am creating Dynamic Rad Strip which is having 3 Rad Tabs namely "Newly Added", "Popular", "Create New". Now I have one button in Rad Tab1(Newly Added) by clicking which, I want to be in Rad Tab3(Create New) enable. I am following your "Wizard" example that switches to the next tab. But in my case, when I am hitting the Button the Error "Object reference not set to an instance of an object" is giving in the line having red color.

private void GoToNextTab()

{

try

{

RadTabStrip tabStrip = (RadTabStrip)Page.FindControl("ForumRadTabStrip");

RadTab professionalInfoTab = tabStrip.FindTabByText("Create New");

//LinkButton1.Text = tabStrip.FindTabByText("Newly Added").Text;

//professionalInfoTab.Enabled = true;

//professionalInfoTab.Selected = true;

}

catch (Exception ex)

{

LinkButton1.Text = ex.Message;

}

Why this is happening?

Regards,

Chandan

[Drag and Drop] Getting ID of GridDataItem dropped on

Hi,

I have a tricky one . . .

My specific requirement is to drag a TreeNode from a RadTreeView to a GridDataItem in a RadGrid and have it populate into the DetailsTableView of the specific GridDataItem the TreeNode was dragged onto.

I already have the solution for dragging a TreeNode into a RadGrid implemented and tested, it works fine.

My only problem I now face is getting the ID of the GridDataItem the user dragged the TreeNode onto. I know it involves some javascript magic and probably a hidden field to store the ID for the server.

Please help me out Telerik Forum, you are my only hope! Any links or resources you can point me at to would be much appreciated.

Showing/Hiding grid column

I have a grid for which I want to hide (or disable) the Delete/Edit columns when the app is in a certain state. I have tried setting the Visible property on the columns in several event handlers in the code-behind, but once I have set the column visibility to false, it stays false, even when the code to reset it to visible is executed.

Can you give me an example of how to do this?

Editing with RadGrid-generated forms

I configured a automatic edit form with multiline text box. Is it possible to configure the text label to orient on top of the field instead of to the left of the field(default behavior)?

Thanks!
