I am unable to get the animation for the panel bar to work in my application.  I literally copied the Demo and still the animation does not work.  I do not understand what is missing.  Clicking on the arrows neither collapses or expands.  It is as if the "click" never happens.

What is the proper procedure to ajaxify controls contained in layout templates of RadGrids or Formviews?

e.g. if RadFormView1 contains an itemtemplate which contains a RadGrid, how does one properly configure the RadAjaxManager to ajaxify the grid?

I tried something like this:

Using this definition (where Radgrid_Addresses is a control contained in the ItemTemplate of the Formview), the ajax request seems to work for the first request to the radgrid (for example, moving to the next page) but subsequent requests (moving back or forward a page again) seem to affect the entire formview rather than just the grid.

Thanks,

Hi,

We are using a stacked column series for our chart display. We have a single stacked bar in display (as attached). I am trying to add a border to each stack/column but I couldn't find an attribute I can use. I tried the approach defined here but that didn't seem to work.

https://feedback.telerik.com/aspnet-ajax/1373488-add-appearance-options-for-the-series-border-in-radhtmlchart

Another thing that I am having to struggle with is I have the chart title visible set to false but there is a white space in that area that I can't seem to get rid of. Is there somewhere in css i can do that?

Attached is the expected and what I see right now. I gave the chart a black background to show what I mean.

Can you help me figure this out?

Hello,
in this example: 

https://demos.telerik.com/aspnet-ajax/autocompletebox/examples/default/defaultvb.aspx?show-source=true

is missing the DefaultVB.aspx.designer.vb

so when I try to reproduce, I get these errors:

How can I solve?

Thank you.

hello

I want to open radgrid header context filte exact coumn header position but it goes to Top ..Please Help Me!!

I have implement a custom provider for RadSpreadsheet as follows:

So the provider looks for an excel file in a predefined location. If the file exists then it is bound to the RadSpreadsheet, otherwise a new file is created. This part of the provider works well with small as well as with bigger files.

The problem is when I try to Save the RadSpreadsheet by clicking the Save button on the toolbar. Save works ok for a few hundred rows. But it fails for a larger number of rows, e.g. 15000 rows. When the Save button is clicked the page freezes and method SaveWorkbook(Workbook workbook) is never invoked.

Hi,
I am using the textbox, RadNumericTextBox and RadAutoCompleteBox inside the grid to receive the values and store them in the DB. However, when a lot of data needs to be input, the speed of binding becomes slower, so virtualization and paging are performed. So, there is a problem of turning the loop to get the data of the grid and not getting the entire data.

RadGridItems.AllowPaging = false; RadGridItems.Rebind(); I need to get the data entered in needdatasource at the time, but I don't know how to get it. Please tell me how to get all the data entered on the paged grid. Please help me its urgent issue.please refer code below.
