I'm trying to bind to the client series clicked  event to implement a drill-down feature. The event, however, is not fired when the chart is rendered as a Canvas but works fine in SVG mode. I even tried to bind the event handler to the underlying Kendo widget but still the event is not fired in canvas mode. I want to use canvas mode so as to keep the page size small.

 Following is the structure of the chart that I used. Neither the OnClientSeriesClicked nor the ClientEvents --> OnSeriesClick work in canvas mode.

<telerik:RadHtmlChart ID="​chart" runat="server" EnableEmbeddedScripts="false"
                                    RenderMode="Lightweight" Height="350" Width="840" RenderAs="Canvas" Transitions="false" 
                                    OnClientSeriesClicked="seriesClick">
                                    <PlotArea>

                                        <YAxis Type="Numeric">
                                            <TitleAppearance Text="Y" Visible="true" />
                                            <MinorGridLines Visible="false" />
                                            <MajorGridLines Visible="true" />
                                        </YAxis>
                                        <XAxis DataLabelsField="Category">
                                            <LabelsAppearance RotationAngle="45" Visible="false">
                                            </LabelsAppearance>
                                            <MinorGridLines Visible="false" />
                                            <MajorGridLines Visible="false" />
                                        </XAxis>
                                        <Series>
                                            <telerik:​ColumnSeries DataFieldY="Value" ColorField="Color">
                                                <LabelsAppearance Visible="false" RotationAngle="-90"></LabelsAppearance>   
                                                <TooltipsAppearance Visible="false" />
                                            </telerik:LineSeries>                                                                                                                                    
                                        </Series>
                                    </PlotArea>
                                    <Legend>
                                        <Appearance Position="Top" Visible="false" />
                                    </Legend>
                                </telerik:RadHtmlChart>

Hi,

I'm developing a web with visual studio in c#.

 I'm want display a Grid and show some data in a chart, but when a user filter the Grid, the Chart refresh its data.

 In my case, I attach an image, I want display de Summary values in chart, but when a user filter the grid, the chart must be updated also.

 How can I do It?

 Another question, in Firefox I display de combos very uglies, with IE I see the combos good. Why?

Thanks

Hi I am trying to add add a RadComboxBox to my RadGrid filtertemplate in a bound column.  For some reason in the code behind I can not access the RadComboBox.  It keeps coming back null.  I'm not sure what I'm doing wrong.  Here is my code.

<telerik:GridBoundColumn SortExpression="Product_Name" HeaderText="Product Name" DataField="Product_Name" UniqueName="ProductName">
                             <FilterTemplate>                                 
                                <telerik:RadComboBox runat="server" ID="cmbProductName" CheckBoxes="true" ClientIDMode="Static" 
                                     AppendDataBoundItems="true" DataValueField="Product_Name" EnableCheckAllItemsCheckBox="true">                                
                                </telerik:RadComboBox>
                            </FilterTemplate>
                        </telerik:GridBoundColumn>

 foreach (var cat in CatProdList)
            {               
                var itemCategory = new RadComboBoxItem(cat.Category.Name);

                var option = cat.ProdAttributesTuple.GroupBy(a => a.Item2.Attribute.Value).ToList();
                foreach (var attr in option)
                {
                    if (e.Item is GridDataItem)
                    { 
                        RadComboBox cmbProductName = (RadComboBox)e.Item.FindControl("cmbProductName");                      

                        var item = new RadComboBoxItem(attr.Key);

                        cmbProductName.Items.Add(item);                    
                    
                    }
                        
                }
            }     

I create web pages for an IT department to monitor many servers.  I use Telerik Rad Controls for ASP.NET.  My problem is that the pages need to read a lot of data and are not quick to respond.  For example, on the Page_Load I query 50 servers (often using asynchronous tasks) to display the information in a RadGrid.  This takes a while and feels unresponsive.  I think I want to be able to display a page immediately and then fill it in as data is returned.  In addition when I make a change to a single server I sometimes query all the servers again to update the RadGrid and display the page again.  Specifically this example could be a question of how to update only parts of a RadGrid (which a recent post said can't be done), but this is just an example.  I may be going about this all wrong.      

What I really want to know is if there are Telerik programs besides Rad Controls for ASP.NET or things within Rad Controls that I should be using/learning to make my pages more responsive (I can't even seem to display an hourglass icon).  I have used UpdatePanels with some effect.  I have also looked into SignalR.  I see many Telerik examples that seem to do what I want, but then end up not working, which could just be my fault.  What products should I be looking into?  I need to use Windows IIS web servers, but not necessarily ASP.NET, but I would like to keep using that if possible.

Thanks,

Scott

Hello,  

I have RadComboBox inside A RadGrid Batch. I need to get DataKeyValue of the row on SelectedIndexChanged of the RadComboBox.

I tried to use : RadComboBox.Parent to get the GridDataItem also I tried RadComboBox.NamingContainer. Both methods didn't work.

Thanks for helping.

Regards,

Abitar

I have 2 situations..............

Number 1 : 

        <div id="container">      
        <input type="text" 
               class="k-textbox" 
               class="k-input k-textbox"
               pattern="\d{10}"
               data-pattern-msg="enter a value according to the pattern"
               />
      <input type="button" value="validate" id="validateButton"/>
    </div>                  

    <script type="text/javascript">
      $("#container").kendoValidator();

      $("#validateButton").click(function () {
        $("#container").data("kendoValidator").validate();
      });
    </script> 

       This is working correctly. Please see​ above input type is text .

Number 2 : 

        <div id="container">      
        <input type="number" 
               class="k-textbox" 
               class="k-input k-textbox"
               pattern="\d{10}"
               data-pattern-msg="enter a value according to the pattern"
               />
      <input type="button" value="validate" id="validateButton"/>
    </div>                  

    <script type="text/javascript">
      $("#container").kendoValidator();

      $("#validateButton").click(function () {
        $("#container").data("kendoValidator").validate();
      });
    </script>​

 This is not working . Please see above input type is number.

So is  "data-pattern-msg" is not supported for the input type "number" ???
