i have a series of "nested" child controls in a .net site.  i need to be able to use the client side api against telerik controls that are layered down in the nested controls from both the aspx page, and "parent' level controls - hope that makes sense.

I have done the same api work down one level, but not successful to date with multiple layers of nesting. 

thanks

Hello,

I'm trying to implement a pretty simple 3 level RadGrid(Master + 2 Detail) and no matter what I try I can't get it to display the 3rd level.  The first two levels expand properly, but the third just expands blank.  I'm sure I'm just missing something simple but wasn't sure where to look.  

Here's my Code:


Any thoughts?

I have a RadGrid that retrieve data on button click via Sql using a repository pattern.  When the downloadPDF button is used the PDF only display the header info.  The remainder of the pdf page is blank.   Below are my codes.  Your help is greatly appreciated.

 

 

 

Again Thank You.

 

 

 

 

 

 

I am having one RadGrid and binding one Datatable to it From codebehind.
At each paging or sorting or drag drop column it goes server side (page refreshed) and then displays.
is there any professional way i can achieve this with faster speed.
my code is


 AND

In each row of a grid with EditType = "Row", I'm trying to show/hide the column editor controls based on data in that row. When some rows are in edit mode (after being clicked on), they will display a text box, checkbox, etc. approporiate for that particular row. Other rows will hide that option in the same column.
For the entire column, edit controls can be shown/hidden based on the column's ReadOnly field. Can this be turned on/off for individual rows?
Would prefer to handle this server-side. Trying to avoid managing dynamically added controls based on data conditions and instead simply turn on/off editing in specific cells of each row.

In the example below, when a row is in edit mode, I want the edit text box in the MilkType column to only display if the Product for that row is Milk. Otherwise the cell should be read-only when the row is in edit mode.

Thanks!

I am trying to create a custom EditForm for use with the RadGrid.  When I edit or insert a record, the other records in the grid display incorrectly.  

My app:
- simple ASP.NET 4.5 web application
- OS: Windows 8.1
- IDE: VS2013.  
- Telerik version - I am a consultant and using the DLLs provided by my client, so I don't have any sort of Telerik SDK installed.  The version of Telerik.Web.UI.dll I am using is 2013.1.417.35 (17MB, dated 5/12/2014 7:50pm).
- Browser: Google Chrome Version 36.0.1985.125 m.  I also tested on IE 11 11.0.9600.17207 (Update version 11.0.10).

I have attached three files:
- Pic1.png: Viewing the data (works fine)
- Pic2.png: Edit the "David" record
- Pic3.png: Insert a new record

I tried viewing source after clicking Insert, but it appears that source in that case is simply the source I see when I view the data.  The custom edit form controls don't appear in that source. 

Note that this is the same behavior as in this post:

Hi there,

I am wondering if there is any support for a floating column chart.  I tried to make my own by creating a Series with a white background, however, the column itself has a gray border.

Hello all first time poster here, I have a bit of a problem with a RadGrid GridTemplateColumn and a dropdownlist is saving back a blank string. Here is the code I am using. I don't know how much you need so I will post the minimum.


When I run the code I see the dropdownlist and it has data and it shows the correct drop down value when displayed.
On the RadGrid1_UpdateCommand it does see the value to hold it in the session but for some reason it actauly saves it back as a blank string.

Hi

I am using radasyncupload to add avatars to my website profile and there is a radimageeditor in the same page. I want to upload a file directly and open it directly in the image editor for cropping. Any solution?

Thankyou
