Hi All,
I’m facing a performance problem with a new website that we have developed. After checking the website with Gtmetrix I got bad results for the bellow

Leverage browser caching
Specify a cache validator
Defer parsing of JavaScript

I’m also attaching a Print Screen. I did a research over the web but I didn’t find a solution for my problem.

Do you have any Suggestion?

How can I force new item to be saved before user clicks "add new" again. Sometimes user press "add new" by accident and the data will be lost.

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;

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.
