Hello,
I am working on a project with a RadGrid.
I need to make a custom filter.
I read your documentation and saw the instructions how to do it.
My problem is that the code works only for string type filters.
I get the following error in line 08 when I try to filter other types:
Unable to cast object of type 'Telerik.Web.UI.RadNumericTextBox'
to type 'System.Web.UI.WebControls.TextBox'.
My grid is generic (columns and data fields types are changed dynamically in run-time).
VB.NET Code:
Thank you,
Daniel

Hello,
We have installed Telerik UI for ASP.NET Ajax (Telerik_Web_Parts_For_Sharepoint2010_2014_2_724_Trial.msi) and configured our SharePoint 2010 to use the RadEditor in List items as it is described here. We also performed an IISreset. Still a simple text box appears (see attached screen capture) instead of the full ribbon as shown into the demo. Note that the RadEditor WebPart works fine.
Could you please help us in understanding the missing configuration?
Regards,
Roger.

Greetings,
I was struggling earlier to figure out why my loading panel was not showing. I inherited an application and was trying to Ajaxify it. One of my Loading Panels would not show up even though it was doing a lengthy post-back. I discovered that having align="left" on a table tag (I know, not good practice) causes the loading panel to disappear. Here is a sample...
I removed the left alignment from the table tags and now working great. Just wanted to share in case somebody else has this issue.

I have a Radgrid with 4 ItemTemplate columns each item template column has a Textbox. I need to fire SelectedCellChanged event when I move (click tab) from one cell (textbox) to other cell (I need to call a method which does calculations whenever a cell is changed). How do i do that?
Thanks in advance.
Note: I'm working on a web application using c#.

I'm struggling with borders on my Grid export to pdf. I have a grid that contains 3 detail tables. My biggest problem is that the 2nd and 3rd detail grids are not exporting with borders. The first detail grid exports with a border. I've tried changing all settings, and tried applying the borders in the code-behind to no avail. I'm also unable to remove borders. I tried setting the BorderType to "NoBorders", but the output still contains borders. Is there an issue with multiple detail tables? I've attached a sample export.

Hi,
I had Radcombobox inside RadWindow. I set z-index of radcombox to be really hight value so that it can appear on top of radwindow when maximize the Radwindow.
The problem I am facing now is I can't see Show more result when I maximized the Radwindow. Please see attached image for example. If I don't maximized the radwindow Dropdown top bar will hide under browser bookmark bar. I tried to put ItemsPerRequest , but it is still now working. Can anyone help me?
Thank you.
Best regards,
Ei

I have a RadTreeView where the nesting is not happening how I'd like. I think it is confusing values from the ParentDataKey and DataKey. I am loading data from two tables - ApplicationParent and Application. The Application table has a ParentId column that is a foreign key to ApplicationParent.
There is one record that I'm having trouble with. See the attached screenshot "treelist data.jpg". There is an app with a ParentID of 100. There also exists an Application with an AppId of 100 and an ApplicationParent record with a ParentId of 100. In the UI, the nesting occurs as shown in the attached screenshots "treelist ui 1.jpg" and "treelist ui 2.jpg". What I want is for the application "UBH PIF Tracking" to be nested underneath the parent app of the same name.
Here is my code for the TreeList markup and for loading the data:
How do you suggest I solve this problem? Right now my only idea is to modify the DB to ensure that there are no ApplicationParents that have a ParentId that is equal to an Application.AppId.

hello experts...i am in a problem if any one can come up with some advise...
i am using TabStrip with two Tabs. Tab loads on demand and Each tab has a control on which i have Gridview. when i press the tab it shows me gridview correctly however, when i press the edit button (or any other button) on the gridview then the gridview disappears. Surely this is because of postback. i am using gridview_needSource event but it does not fire not even a single time.
when i use the tab on the aspx page then on Edit button of gridview the gridview_needSource event fires where i fetch the datasource from the Viewstate back to the grid view and gridivew loads again.
how can i control disappearing of the gridview on the control?
