Hey

I am having a issue where my chart displays grey when I update it with new values.

When the page first loads I can see the grid (with no data), my x and y axis, legend, and the title. Once I bind data to it, the whole grid turns grey but I am still able to see everything else.

Internet Explorer also pops up a dialogue that tells me that a script on the page is causing my web browser to run slowly.

 

However I don't have this problem on my local computer, only on the computer I'm trying to deploy this on.

Attached is a picture of what the Chart looks like when I try to load data to it.

Hi,
I am using the NeedDataSource event to populate my grid from my DB & I use a custom popup form for editing. The edit form is driven by a link created using 'AutoGenerateEditColumn' and then handling the OnCommand event.

I would like to add my own button to the grid to popup another form so it could be either a 'custom' command (if such a thing exists) or I need to add a GridButtonColumn from code-behind.

I couldn't find an example of how to do this - any ideas?

Hi Team,

 

I'm using Telerik controls "RadControls for ASP.NET AJAX 2011.3 1305" , I developed a Rad Grid with modal popup,When I click on edit button ,a Modal Popup will launch with grid item editable, in my local environment it is working fine but the same thing is not working after deploying it into Development servers.

This issue is happening in IE, I'm using IE 11.

 

Thanks in Advance.

Hi,

Am binding the RadGrid from dynamic data table in codebehind. After insert or updates happen the grid is not binding.

Below the code for reference.

I am having some display issues in the scheduler its courrupting the date when i switch to week view all other views are fineis theri any way of making the cell taller?.

 

 

I am trying to copy/paste a delimited string into the AutoCompleteBox such as follows -  test@test.com;test2@test.com;test3@test.com

The expected behavior would be to tokenize all three of those entries; however, it only takes the last entry and removes the others.  Is there a way to get it to tokenize all 3?

Hi

 

How to load dropdownlist based on group for ex: 

 

ex:

India 

   Tamilnadu

   Andra

Srilanka 

  State1

  State2

 

In telerik dropdownlist

Hi

 

How to select Multiple option dropdownlist in telerik control any one guide me.

 

http://demos.telerik.com/aspnet-mvc/multiselect/serverfiltering

As you can see in the attached image, the edges of the list of records are not border radius format. The examples in the online demo instead and there are no particular settings to make the object. How can I fix?

How can I fix? here is the html code

 

Also how can I enter the search button in the search button?

 

I was getting performance issues, and I finally managed to trace it back to the code in ItemDataBound(). For some reason, every record was being databound four times. So I grew curious.

I created a new project, threw a radgrid on it along with a SQLDataSource that ran a simple 53-record SELECT stored proc. In ItemDataBound() I set:

Debug.WriteLine("ItemDataBound");

Then I did the same with a basic GridView. In RowDataBound(), I set:

Debug.WriteLine("RowDataBound");


When ItemDataBound ran, it came up with 108 lines (106 for the records 1 for the header, and one for the footer). When I ran RowDataBound(), it came up with 55 lines (not sure where the extra one is coming from. Possibly a footer that's not visible?)

So why is it running twice? (Or in my case, four times?)
