If paging is disabled and the PageSize is set to less than the number of records bound to RadGrid, client item templates are not all rendered correctly.


If PageSize is 10, and records bound to Grid are 15, then the first 10 records will have templates rendered correctly, while the rest of 5 records will not.

We recently added row group functionality to our grids and we and our users are very happy with this.

Only thing that bothers us is the drop functionality on the grouppanel. We have an wish to make the drop functionality of the grouppanel much more intuitive. Especially when the RadGrid is already grouped on multiple columns.

Possiblity to drag a new, not grouped yet, column to the grouppanel to the position/order where you want the grouping of the grid to come up with. E.g. drag the next column between the first and the second grouping column. It is not possible to add it at a specific location.

 this case can be reproduced on the RadGrid Grouping demo on your site:

Microsoft Edge 44.18362.449.0

Telerik Control:


Teleri Version:  Version=2017.3.913.45,


When a item is selected and a postback is occured, the SelectedValue returns an empty string.

Expected behavior:

The correct SelectedValue should be return.

Thing that have been tried so far:

1: upgrade the telerik to the latest version (2020.114) ---> issue persists

2: set autopostback to "true" problem solved

3: use other browsers (chrome, FireFox, new Version 79.0.309.68 ) issue disappears

Sample code: 

1: aspx

        onitemsrequested="ddlSupplier_ItemsRequested" autopostback="false">

2: code behind

protected void Page_Load(object sender, EventArgs e)
    protected void saveIssue_Click(object sender, EventArgs e)
    protected void ddlSupplier_ItemsRequested(object sender, Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs e)
        RadComboBoxItem li = new RadComboBoxItem("Alan Jones (Brunel Systems Pty Ltd, test site)", "123");
         li = new RadComboBoxItem("Jackie Chiu (Optimum Construction, Optimum Construction (Sydney)) ", "23" );
         li = new RadComboBoxItem("Erik Baker (Optimum Construction, Optimum Construction (Sydney))", "2323");
    protected void b_Click(object sender, EventArgs e)
        var a = ddlSupplier.SelectedValue;  // most of the time returns "" for Edge

Without using radFilter to setup multiple filters before applying RadGrid can only be filtered one column at a time. Can a button be added to the Grid when filtering is applied that when Clicked will filter the Grid based on all of the column filter selections that a user selects?

When loading custom skin trough  RadSkinManager -> Skins -> SkinReference.Path, the logic inside RadSkinManager.FillNonEmbeddedSkinsInfo does not work correctly: in order to load ComboBox.MySkin.css, per say, it requires ComboBox folder to be present inside the custom skin folder.

I would like radCloudUploader to be able to integrate with DropBox (and skydrive?) 
As my client has a large investment in DropBox (cos it works on mobile), but I want to be able to upload documents to a given project (subdirectory) via a single interface without giving them total access to that directory.

I would also like to have some integration to a search service such as Azure Search 
so that documents uploaded can be searched.

Which results in me adding lots of 'meta data' to the file that is being uploaded, but the actual content can have a free text search on there.

Such an exposed method, which returns the value from the ExportOutput, would be useful to further enhance the exporting capabilities of the RadGrid control. A very practical example would be to export numerous RadGrid controls into one Excel file.

Hello @support!

Did you observe the behavior, that Firefox (v71.0 64bit) does not turn the rad grid into edit mode, whereas IE11, Edge, Chrome (v78) perfectly work ok on the same grid?

Clicking the edit stencil button only makes the two arrows below rotate for some seconds, but nothing happens. What could that be?

Video Demo is attached.

Thank you,

We want the Kendo chart widget (RadHtmlChart actually) to blend in with the webpage we use it in. In this page, we use font-weight 300. Since there is no way to specify the font-weight in the chart, we have had to use a hack to specify it:


            function chartLoad(chart, args) {
                chart.get_kendoWidget().setOptions({ title: { font: "20px sans-serif; font-weight: 300" }});


This is not only a clumpsy hack, but it also make use of a custom skin impossible (for setting the font).

We use the Telerik RadGrid for our application and we have found that if we click on the filter button on the RadGrid, it will make the page scroll.
