Hi,
I have encounter a new bug with my export pdf.
It was working in 2016 R2 SP1. I was in 2016 R3 when we discovert it first and upgrading to SP1 and SP2 didn't fix it.
So i have a function in code behind that process a predefined telerik report and send it via 'Response'.
protected void ExportButton(object sender, EventArgs e) { // [...] HiddenCode [...] ReportProcessor reportProcessor = new ReportProcessor(); Telerik.Reporting.InstanceReportSource instanceReportSource = new Telerik.Reporting.InstanceReportSource(); instanceReportSource.ReportDocument = rpt; RenderingResult result = reportProcessor.RenderReport("PDF", instanceReportSource, null); string fileName = doc + "." + result.Extension; Response.Clear(); Response.ContentType = result.MimeType; Response.Cache.SetCacheability(HttpCacheability.Private); Response.Expires = -1; Response.Buffer = true; Response.AddHeader("Content-Disposition" , string.Format("{0};FileName=\"{1}\"" , "attachment" , fileName) ); Response.BinaryWrite(result.DocumentBytes); Response.End();}
If i have a RadButton outside of the grid calling this it works. When the button is in the CommandItemTemplate I get Nothing.
Or i get just some server lag.. sometimes a js unnamed error. and that on every Browser.

Telerik Grids are Binding In this way Please look into attach image. its Binding with odd behavior in all browsers that is clearly mentioned in attach image. Its just for single Search ID from system . For other ID's Grids are Binding and its working fine. But not for Single ID. like 4567 on Search. And console error is prompting just against this ID not for others .Please Help me out .. Help will be Appreciated !!

Hi,
I have a treeview that is built manually (no data-bind) using the metro theme. I'd like to set some node colours to red but neither of the two options below seem to have any effect?
ret.CssClass = "red";ret.BackColor = Color.Red;

I'm trying to add data/item to a listbox with custom ClientItemTemplate where I'm not using Text or Value but using other variables.
<telerik:RadListBox ID="AlarmListBox" runat="server" Height="100%" Width="100%" RenderMode="Lightweight" ClientDataSourceID="AlarmClientDataSource" OnClientSelectedIndexChanged="OnListItemSelected"> <EmptyMessageTemplate> <asp:Label runat="server" Text="No Alerts"></asp:Label> </EmptyMessageTemplate> <ClientItemTemplate> <div class="alarm"> <div class="alarm-wrapper"> <img src="#: src #" class="img-responsive alarm-list-image" style="float: left" ;/> <dl class="alarm-list-details"> <dt class="name">#= type #</dt> </dl> <div style="clear: left" /> </div> </div> </ClientItemTemplate></telerik:RadListBox>At first, I was using the listbox without a data source and I was able to add to the data by setting the attributes of a new listboxitem from the client-side.
Then I wanted to use a dummy REST service to test populating results.
I was able to populate the listbox using the clientdatasource using "select" only.
Now I want to be able to use both functionality, to populate the listbox from the REST service and manually. I tried to add directly to the listbox but it failed because their is no attributes and when I added items to clientdatasource using add() method but the new item did not appear in listbox.
Which method of adding an item is correct bearing in mind that I want to update the results to the REST service eventually and how can it be done.

I was trying to use a listbox with clientdatasource. But since the listbox cannot be rebinded yet, I decided to switch either grid or listview.
I was having some trouble selecting an item from listview so I'm using a grid with clientitemtemplate to fit by data into a single column.
What I want is to apply the ripple effect available when selecting an item in listbox to the grid,
so when I select a cell from the column it will have the ripple effect.
if you can please provide me with a solution.

Hi,
I have a RadGrid with EditFormType="WebUserControl". In my usercontrol I have a custom validator to check the value and allow to update or not.
My problem is that _dataItem is null on the CustomValidator_ServerValidate event.
I try this code :
public object DataItem{ get { return (object)ViewState["DataItem"]; } set { ViewState["DataItem"] = value; }}But even with ViewState DataItem is always null (in CustomValidator_ServerValidate event).
Have you a solution ?
