how to access the parent table column value in child table when we using the hierarchy of telerik Radgrid.

cs source-

protected void cmpreportgrid_OnItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
    {

         if (e.Item is GridDataItem)
        {
            if (e.Item.OwnerTableView.Name == "CompanyListDetails")
            {
                if (e.Item is GridDataItem)
                {
                    GridDataItem item = e.Item as GridDataItem;
                    Viewing view = item.DataItem as Viewing;
                    if (!view.isgroupcontact)
                    {
                       
                        item["ExpandColumn"].Text = "";
                    }
                    
                }

       else if (e.Item.OwnerTableView.Name == "GroupContact")
            {
                e.Item.OwnerTableView.ParentItem.Expanded=false;//how to get the parent table column here to set the condition for expandcolumn.
            }

I am attempting to upgrade a .Net web app with Telerik RadControls Q3 2011 to Q3 2013 and have run into skinning issues with the RadGrid.  The browser is also being upgraded from IE8 running in Compatibility View to IE11 in Edge Mode.

​Attached (IE8_RadGrid_Border.jpg) is what the RadGrid used to look like and needs to maintain its appearance.

Attached (IE11_RadGrid_Border.jpg) is what the RadGrid looks like after upgrading the Telerik .dll's and running in IE11. 

The issue is the gray border at the top and bottom of each cell is missing. 

Could this be a sizing issue?

Thanks,

Rob

Hello folks.

I was looking for a way to export my Telerik Chart image for use in documents and for printing, but didn't find a clean "Telerik solution" to the problem. The chart components features the Save(..) method, allowing us to save the generated image to the web-server. However, this is not what I wanted - I want to serve the image directly to the user as a download without writing it to the filesystem on the server.

Fortunately it is possible to save the image to a MemoryStream, so the following few lines does exactly what I need:


The browser will now pop up with the download dialog, allowing the user to either open or save the file.

If you want to have the image displayed in the browser, simply comment out the following line:
this.Page.Response.AddHeader("Content-disposition", "attachment; filename=Chart.png");

Hopefully this tip will be useful to someone else :)

Telerik team: Wouldn't it be possible to implement the code above in an Export function, allowing less expirenced users to do export without worrying about memory streams, response headers and so on?

Hi,

The combination of GridCellSelectionMode MultiColumn and UseStaticHeaders does not work, nothing happens onclick. 
Without UseStaticHeaders theres no problem to multiselect columns.
I have generic grid columns, all added programmatically.
Any solutions?

Best Regards

Hello.

I have a quick question.

Is ther any way to use the Ajax Loading Panel for all Controls on my site that doing a Postback?
I don't want to define all controls in the manager that do a postback.

I just want the ajax loading panel to show up every postback.

Is this possibile?

Thank you for reading.

Dear all,

I am trying to create a raddock control with title bar handle that can be expand/collapse horizontally rather than the vertically like in traditional demo http://demos.telerik.com/aspnet-ajax/dock/examples/overview/defaultcs.aspx

Any brilliant idea to share? Greatly appreciated.

Kind regards,

Jonathan

Hi

I have a RadGrid with 3 columns. One of them is a GridDateTimeColumn of type DateTimePicker. I'm trying to set the default time to 4pm instead of midnight when a date is selected.

I found code on another post that shows how to set the default time for a RadDateTimePicker by using a client event for OnDateSelected but I can't get it to work if the datetimepicker is in a grid.

I added a client event for onDateSelected in the code behind (in the RadGrid1_ItemCreated sub) and it does get called when I select a date but it gives me an error when I try to set the time. The error is "Sys.ArgumentNullException: Value cannot be null. Parameter name: instance"

The client event code is

 <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
   <script type="text/javascript">  
       var isTimeSet = false;
       function timeSelecting(sender, args) {
           isTimeSet = true;
       }
       function dateSelected(sender, args) {
                        if (args.get_oldDate() == null && !isTimeSet) {
                            args.set_cancel(true);
                            isTimeSet = true;
                            sender.get_timeView().setTime(16, 0, 0, 0); //I'm getting the error on this line
                        }
                        if (isTimeSet) {
                            isTimeSet = false;
                        }
        }
    </script>
   </telerik:RadCodeBlock>

This code does work with a RadDateTimePicker on the page but won't work for the RadDateTimepicker on the RadGrid. Is there any other way I can set the default time? I'm using version 2013.3.1114.40

My RadGrid -

Adding Client Event in code behind

 Protected Sub RadGrid1_ItemCreated(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemCreated
        If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then
   If TypeOf e.Item Is GridEditFormInsertItem OrElse TypeOf e.Item Is GridDataInsertItem Then
               
   Dim editor1 As GridDateTimeColumnEditor = CType(item.EditManager.GetColumnEditor("TEST_DATE"), GridDateTimeColumnEditor)
               
   Dim dtp1 As RadDateTimePicker = editor1.PickerControl                
               
                 dtp1.ClientEvents.OnDateSelected = "dateSelected"
                 Dim rtv1 As RadTimeView = editor1.SharedTimeView
                 rtv1.Interval = New TimeSpan(0, 30, 0)
   rtv1.OnClientTimeSelected = "timeSelecting"
             End If

I have an aspx web application develop with the Telerik ajax control suite version 2012.2.812.40 which is running on a Win2003 server and IIS version 6.

When the app is deployed under a virtual directory off one of the existing web sites it runs correctly, but when it is deployed on its own site, the Telerik controls are rendered with a different look and do not function properly.  The textbox control is used on the login page and in the latter case the width is smaller and the control always return a blank string to the logic, regardless of what is entered (the app therefore can't get past the login page).  See the attachments below; the urls for the sites are as follows:

Main Site: www.happc360.com
Virtual Directory Site: www.westernesse.com/happc360

Both deployments are pointing to the SAME location on the web server and therefore are running exactly the same code, style sheets, config, etc.  They are also running in the same application pool.

I have gone over the IIS properties of the main site and the virtual directory with a fine tooth comb, but can't see any significant differences.

What would be causing this?
