Hi all,

My snip code as below : 

In the marble skin, we see two params {image}  and {plotarea}. If we do not custom css, chart can show the background. However, I want to custom some its style, its background cannot show.

Please help.

Thanks / Phong Dang.

We have a very strange problem, we have a RadGrid that is invisible inside an UpdatePanel, that is set as the receiver of AJAX requests (along with other control). When the sender initiates an AJAX request, the RadGrid will try to DataBind, even though it is still invisible, which seem strange. Is this really expected behaviour or is it a bug? In my world, and invisible RadGrid should never try to DataBind by itself (all data operations for the grid is handled automatically).

hi

This is my code:

<ResourceTypes>
                     <telerik:ResourceType DataSourceID="sdsUsers" ForeignKeyField="UserID"
                         KeyField="UserID" Name="User_Name" TextField="User_Name" />
</ResourceTypes>

    Protected Sub RadScheduler1_AppointmentDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.SchedulerEventArgs) Handles RadScheduler1.AppointmentDataBound
        If e.Appointment.Resources.GetResourceByType("User_Name") IsNot Nothing Then
            e.Appointment.BackColor = DataBinder.Eval(e.Appointment.Resources.GetResourceByType("User_Name").DataItem, "BackColor")
        End If
    End Sub

My user table schema:

UserID
User_Name
BackColor

I still do not get any color for the scheduler. What went wrong with my setting?

How can I make the cover flow items clickable? The demo doesn't do this.

Thanks!

Hi,

I am working on a scenario where Feeds are downloaded from a web URL. Since this feed downloading can be a time taking process, I want to shift this logic and grid databinding to Async mode.
I did checked different threads talking about NeedDatasource to other approaches but none of them is working for me. Given below is code for your reference:

if (index == -1) {

 

 

newsDetailURL = newsDetailURL.replace(

Hello,

  I am on Q2 2010 SP2. I have a rad panel declared like this.

<telerik:RadPanelBar runat="server" ID="RadPanelBar1" Width="100%" Visible="true" EnableViewState="true">
  <Items>
    <telerik:RadPanelItem Expanded="true" Text="Transfer1" runat="server" Selected="true" PreventCollapse="true" style="font-size:10pt;font-weight:bold">
      <Items>
        <telerik:RadPanelItem Value="Transfer2" runat="server" Width="100%">
         <ItemTemplate>
          <div style="background-color: #edf9fe">      
            <table width="100%">
                <tr><td width="15%"><b>Order Number : </b></td><td align="left" width="40%"><b><asp:Label ID="lblOrderNumber" runat="server" Text='<%#Bind("OrderNumber")%>'></asp:Label></b></td><td>Customer ID:</td><td align="left"><asp:Label ID="lblCustomerID" runat="server" Text='<%# Bind("CustomerID")%>'></asp:Label></td></tr>               
            </table>
    </div>
   </ItemTemplate>
  </telerik:RadPanelItem>
 </Items>
</telerik:RadPanelItem>
        </Items>
 </telerik:RadPanelBar>  


Is it possible to Bind the "Transfer2" RadPanelItem to a Datatable  and have the ORderNumber and CustomerID fields set from the first row in the Datatable?

Thanks,
Kavitha

Hello Everyone,
I am binding the Grid inside a loadHeader method and inside that method, I need to call an event called raIseChangedEvent. Inside raiseChangedEvenet, I need to find the label control inside the gridview and get the value of it. I am not sure how to do this. I did this long time ago  using asp grid, but here with radGrid, I don't know how to do this. below is my code

public loadHeader()
{

    RadGrid_Header.DataSource = HeaderList;
         RadGrid_Header.DataBind();
         RaiseChangedEvent();

}

 

    protected void RaiseChangedEvent()
    {
       // This is what i did with asp.net gridview
         grd_view_tracking.SelectedIndex = 0;
        GridViewRow selected_row = grd_view_tracking.SelectedRow;
        string job_seq_text_val = ((Label)selected_row.FindControl("lbl_job_seq")).Text;

      

    }

How can I get the value of job_seq_text_val  in RadGrid.

Any help will be greatly appreciated

Hi,

A quick question (I hope) - is there a limit to the number of levels in a hierarchical RadGrid?

Thank you,
Donna

Hi,

How do I modify the ListBox to allow the user to select / deselect (toggle) each item simply by clicking it, i.e. without pressing CTRL?

Thanks,

hi,
scenario is like this,
i have a radgrid  is populated successfully. on this grid a button is put.
when this button is clicked a radwindow is displayed. In this radwindow a grid is put and this radgrid fetch the record from database.
this child radgrid that is put in Radwindow when populated with 2000 records from the database using ORM, takes almost 10 min.
is there any way so that data can be populated in this grid in fast manner.


Thanks to all.
