I am using telerik grid to display master datail data. On a page load the grid wil populated with the data. I am using NestedTemplateView to display detail data. So there is "+" button on the grid which will display detail data. On clicking "+" I am passing one of the column value for a perticular row to stored procedure and displaying the data(Only one row). The issue is it is working for first row and when user clicks on second row the first expanded detail informaion is not hiding. it remains onpen and displays newly clicked rows details data.

Any idea how to hide previous expanded detail row.

Thanks!!!

HI

           I am Working on RadGrid with FormTemplate as Popup,Once clicked on Edit record of radGrid
popup is shown,This Popup contain dropDownlist on selected index of this dropdownlist i need to
disable some controls using Javascript how can u do it,Please let me know

I am using Telerik for the first time with SQL Server instead of Oracle. I am coding this in C#

I use the following code:


When I perform an edit eveything is fine but when I try and perform an isert I get the following error:

DataBinding: 'Telerik.Web.UI.GridInsertionObject' does not allow indexed access.

There are a few fields in front of this code that work fine. Why is this happening? Do I need to write a code aroubnf for this?

Here is the table breakdown.

Hi Telerik Team

This only happens in IE not firefox. Radeditor sometime add <br/> after the html, when I called getSelectedElement it will not detect the tagName correctly, so I can't restore the link value correctly in my custom dialog box. Even the hyperlink manager can't handle it.

E.g.

Hello,

Why when i use the "LoadContentFile" method ot the "LoadXml" method a new instance of RadListBox has been created.
If i use these methods, first it goes into the constructor of the listbox.

Below is my class inherite from RadListBox


If i create an instance of MyListBox and call to LoadContentFile("LB.xml) then first it to the MyRadListBox Ctor.


Is there any option to avoid this? it pretty annoying and cause to bugs.

Is there a property that can be specified that will change the start angle for pie charts? It looks like it always starts plotting from 0 degrees.

Thanks,

Is there a way to make the radgrid display a message when there is no datasource?  (This is helpful when the radgrid is first displayed)

NoRecordsTemplate

 

 

only works when the datasource is empty (not null).

Hi,

I have a simple gridview which contains a field for primary key "Vendor_ID" which should be filled by a sequence. I changed the property of the field and set ReadOnly = true. >> here i can insert a new record
but when i try to update the record (i have set the condition where vendor_id = vendor_id) nothing happens >> i guess because it can not read the ReadOnly field.
then i have added ForceExtractValue="InEditMode", my records are updated but now i can not insert a new record i receive an error.

Your Help is greatly appreciated.

i'm a little stuck, after i was able to bind an event _SelectedIndexChanged to a combobox of a editform.
now i'm receiving the event in a handler ..._SelectedIndexChanged(ByVal sender As Object, ByVal e As RadComboBoxSelectedIndexChangedEventArgs),
but now i'm supposed to feed another column/textbox of the grid with a value based on the selecteed value of the combobox.

i can imagine (/read somewhere) a solution would be the creation of a custom editform and then using a panel or something to "findcontrol" the textbox, but my editform is generated auto, so is there a way? 
of course
Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)
Dim editMan As GridEditManager = editedItem.EditManager
If (CType(editedItem.Item("Value1").Controls(0), RadNumericTextBox).Text) > 0 then.... etc.

doens't bind to e.item which is RadComboBoxSelectedIndexChangedEventArgs,
so can i get to the editForm through RadGrid1.Mastertableview. ...? Or via FIndControl("..") ?

Hi all,

we build a very simple scrolling-example (using codecharge studio 4.1) but we get always the following server error message. All other telerik asp.net ajax applications and functions (charts, editor, combo boxes ...) we tested makes no problems (congratulation on the very good work of developers!). But after insert the <clientsettings .../> row in the code we get this error message. We use Windows xp / windows 2003 server and asp.net latest versions, IE7 and firefox latest versions, 2008Q3 trial latest build ... The problem is independent from windows, browser etc.

Has anybody an idea? Is this a bug?

thanks for help.
Regards Christian
