Pdf export BUG

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.

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;

Adding items to listbox with ClientItemTemplate and ClientDataSource

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>

</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.

[Solved] Cell Selection Ripple Effect

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.

Edit form - Usercontrol - DatatItem is null

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 ?
