Hello,
I'm using Telerik RadGrid to present some objects to user. When the grid is filled thru NeedDataSource event, everything works fine. But I'm experimenting with asynchronous data loading and binding data to grid thru RadGrid.Datasource seems better for this.
My problem is that when I bind data this way - setting RadGrid.Datasource and calling RadGrid.DataBind(), than the DropDown list for choosing PageSize stops showing the selected pagesize. The dropdown list alone works fine, I can change to different number of items per page, but no matter what i do, the number is not visible.
Sorting and filtering of the data is done in WCF service, so I have set AllowCustomPaging to true and I set the VirtualItemCount just after setting the DataSource property (just before calling DataBind()).
The grid then looks like this:
RadGrid

How set node visible to false in PageLoad, i get error System.ArgumentOutOfRangeException....

 

Hi, above all im a rookie on this and im paying the price...

The thing is, i have a RadGrid and a Div that contains another controls (text boxes and combos), the div has the property runat = "server" and visible = "false"

The point is, with the item command i need to pass the values of the row to the controls of the div and of course change the visible property to "true"

I dont care if the solution is using another control instead the div, i need to show and hide sections of the page with the imer command of the grid, but to this moment is impossible to me

 

thank you

I recently had our application scanned by Veracode and every Telerik control used had a XSS flaw where script could be injected in the ClientState of all controls and successfully executed after the control rendered. Am I missing some property to scrub the ClientState or is this a true flaw? Please advise.

Example:
Injected "><script>alert(String.fromCharCode(104,78,108,53,56,82,111,83))</script>  into RadMultiPage1_ClientState and got an alert.
Expected that the injected script would be removed.

Hi we have a dataset generated from SQL and within this dataset we also have an extra table where its the source of a lookup.

We have a grid operating in batchmode (inline editing) which we create programmatically. We want to have a dropdowncolumn which is bound to that extra table.

Please dont tell me that to implement this we need to implement templates its a simple requirement .

Hi everybody,

   I have a question about how I can compare the current time against the schedule appointment. I set up the appointment with the Start date time (12-01-2016 7:00 PM), End date time (12-01-2016 7:15 PM), and the Recurrence Rule(Recur 1 time every week on Thursday). When the time comes, I'll display my image. For instance, if the current time is 12-01-2016 5:00 PM, my application does not show the image, and it does show up when the time is 7:01 PM. What is the best way to compare the current time against the appointment. I attach my screenshot here as well.

   We purchased UI for ASP.NET AJAX from Telerik. If you need our license number, I can ask our IT department. Thank you.

Thanks a lot.

Hi all,

 

I've managed to add a filter on a dropdown column in my grid, which allows me to easily look for the correct data in my list. But the issue here is that I cannot filter the list with the filter option "Contains". It always returns me the "EqualTo" values. I need it to work with Contains.

Here is my code:

 

Thanks in advance for your help

PROJECT DESCRIPTION 
I am working on a web application that provides spreadsheet functionalities. We were using Office Web Components before and now trying to replace the same with Telerik Rad Spreadsheet. As per the guidance in this url http://docs.telerik.com/devtools/aspnet-ajax/controls/spreadsheet/getting-started.html#creating-a-simple-radspreadsheet I tried to add references. But the DLL versions are different between Spreadsheet and Documents.Core.dll. So this is erroring out. Can you please help on this.

I have a radscheuler with RowHeight set to 205px. In timeline view , when I have a lot of appointment at a same time, I have the following error :

I already had a similar issue in my code and it was because max Unit type size is 32767 pixels.
