I am evaluating RadGrid control. I am having two issues in the evaluation

1. Cascade dropdown loading

There is one ASP dropdownlist for "Project" selection in asp.net page. Once I select the Project from dropdownlist binding the related data in RADGRID in Batchedit mode. In that one column "Module"  RadDropdownlist is populated in grid prerender event. In another column "SubModule" RadDropdownlist is there.
I want that, if I change the Module dropdown, the "SubModule should be populated. Each row may have different module, so each row submodule should be different. RadDropdownlists are in Edittemplatecolumn
How to achieve this? Can you please share the code.

2. I am using RADTextbox in the same grid for "Description" column. If type text and want to give carriage return by pressing enter key. When I press Enter key the focus is lost from the control. I want to type the text with carriage return in this text box. How to achieve this?

Please help me with code samples.

Thanks in advance

Hi Team,

I have a grid with some rows in it. When I expand each row I am displaying the 3 tabs.
I wanted to implement the following scenario.

1)Based on some predefined values(we defining them in enumerations.cs file)need to select the one of the tab by default.
If the enum value is zero need to make the  second tab selected by default and if the enum value is 1 need to make the third tab selected by default.

I am using the telerik dll version of 2014.3.1216.45 and implementing batch editing functionality.

What is the recommended method of accessing a record's old values when it is updated via a data form control?  I've tried accessing 'e.Item.SavedOldValues' from the 'ItemUpdated' event, but the values are null.

I am attempting to increase the performance of the Radsheduler by pulling only those appointments within the visible range. The control is extremely slow if I do not. I have recurring appointments that span 3 months and if I navigate past the original appointment and retrieve the appointments from my database based on the visible range I lose the recurring appointments. If I expand the range to overlap the original appointment I get all the recurring appointments. Is there a way to query via linq using the visible start and end range and still get the recurring appointments without having to increase the range which defeats the purpose of using only the visible range? The documentation below contradicts itself from one sentence to the next. If I utilize a great deal of recurring appointments them I stuck with poor performance?  Getting all data from the database is really not an option because the control performs terribly.

From Documentation:

You can use the RadScheduler properties to optimize your query. For example, the VisibleRangeStart and VisibleRangeEnd properties can be used to limit the number of records that the query retrieves. Recurring appointments are evaluated in-memory, however, so they should be always retrieved regardless of VisibleRangeStart and VisibleRangeEnd.

Hi,
I want to use a Radcombobox like this : Radcombobox template in my advancedform.ascx.
But javascript functions seem not to be called.

P.S : the radcombobox works fine in a simple aspx page.

When I upload a Picture using Image Manager I want it to be scaled down to max width of 400px (according to scale) if a picture is about 1200px wide.
How can I do that?
If an image is about 250 px, do nothing.

And i try "Resizing an image during upload" in Code Library/Editor
If I choose a .jpg file and uploads it is saved with the name and extension as the original. But it is converted into .png
How can I change it? I upload a .jpg image I want it to still .jpg after it is stripped down to the new size

It seems like the built-in styles for PanelBar using the Metro-skin has it's styles defined with !important which makes it impossible to override for us.

.RadPanelBar_Metro .rpSelected,.RadPanelBar_Metro .rpExpanded {background-color: #25a0da!important;color: white!important;border-color: transparent!important;}

Is this by design ? The Silk-skin does not have !important defined on its style from the Telerik.WebResource

I saw another post about a similar query, where a solution was to use the PreRenderComplete to make sure our own css are loaded AFTER the built-in Telerik ones. However we are using MasterPages where this approach won't work.

Hi,
           I want a grid export to PDF but after exporting formatting not showing on PDF.

I  am using this style for formatting but it not works

   item["Average"].Style["font-weight"] = "Bold";   item["Average"].Style["text-decoration"] = "underline";

OR
   item["Average"].Font.Bold=true;       item["Average"].Font.Underline=true;

I have implemented a RadProgressArea for a RadFileUpload control.  Works great locally but when rolled to my production server (IIS 7.5) what happens is this:

1. Select a file
2. Click Upload
3. I select a large file so it takes a while
4. I see the time remaining ticking down, 8, 6, 4, 2, 0 and THEN AFTER the time remaining has went to 0 then the progress bar starts moving to the right, 20%, 44%, 100%.

So I put event log entries in the code to try and see what's up.  I tried every forum suggestion on web.config changes, handler changes and none of that works.  However I have found the issue.  I update the progress bar in my server side code.  I have a method that uploads my file in chunks to the destination folder and as it is doing that I update the RadProgressContext.  Here's the problem though.  When I click my Upload button it takes EXACTLY the length of time to upload the file before that server side button click method is executed.  So in step 4 above as that time is ticking down the RadProgressHandler is being called client side and then once it is completed my button method is executed and my progress bar starts updating and the file is ACTUALLY being uploaded then. 

Can someone explain to me what the crap is going on?  Why is it when I click my Upload button (it's just an asp.net button) it acts as if the file is being uploaded and then once complete with time remaining of 0 the actual button click method is executed?

Hello,

We have implemented RadProgressArea in our web application for Import function.
We are reading file and then processing each record one by one to insert/update in database. It is long running task depends on file's data. We added RadProgressArea to show import progress in percentage. We did not use RadProgressArea in file upload though.

It is working fine in our local environment but when we posted that on server, it is not working. Progress bar is not shown in Firefox, IE10 shows sometime and in chrome shows from start but not update percentage count.

We read articles and forums but did not find perfect solution for that. We make all web.config changes as per the article.

Can you please guide us in that?

Regards,
