Hi,
I am trying to export my radgrid to PDF.The file is exported fine but radgrid in the pdf file has table and cells with dark black border. I tried several things in itemcreated and itemdatbound event but it is not changing border color or bordertype. Text color can be changed easily but not border color. Any help would be appreaciated. Please see attached image from pdf file. I would like to change cell border and table border.

Rendering multiple series

Hi,

I have a HTMLChart containing 19 series(x:DateTime, y:Double) each containing approximately 240 values.
Each point have a tooltip that uses kendo.format to show the DateTime and the double.
Transition is set to false.
MinorGridLine is set to false.
MarkersAppearance size set to 2 and square type.
LineAppearance size set to 2.

It render fine in IE9 and +.
But I have to support IE8, the rendering is very slow and the popup about slow script is showing up.

Any way to improve performance or to render differently or partially the chart?

Thank you.
Xavier

Grid Make every row editable with GridDropDownColumn

Hi,

I'm using the RadGrid to populate a list of objects; Document.
I'll like to make every row editable, but currently only the last row has the GridDropDownColumn enabled.

Please help!.
Thanks!

TreeView in RadPane in RadSplitter Issue

After upgrading to version 2012.3.1205.40, the following code:

<telerik:RadSplitter ID="trsCWCMPrimary" runat="server" BorderWidth="0" BorderSize="0" BorderStyle="None" Height="520px" LiveResize="true" Orientation="Vertical" ResizeMode="Proportional" Width="100%">

<telerik:RadPane ID="trpCWCMPrimaryTree" runat="server" Collapsed="false" Width="20%">

<telerik:RadTreeView ID="trtvCWCMPrimary" runat="server" CssClass="sfecua_chkrdo_dataLeftSmall" Height="99%" Width="100%" OnNodeClick="trtvCWCMPrimary_NodeClick" OnNodeCollapse="trtvCWCMPrimary_NodeCollapse" OnNodeExpand="trtvCWCMPrimary_NodeExpand" onclientnodeclicking="OnClientNodeClicking">

</telerik:RadTreeView>

</telerik:RadPane>

<telerik:RadSplitBar ID="trsbPrimarySecondary" runat="server" CollapseMode="Forward"></telerik:RadSplitBar>

<telerik:RadPane ID="trpCWCMSecondaryTableDetails" runat="server">

</div>

</div>

</div>

</telerik:RadPane>

</telerik:RadSplitter>

</td>

</tr>

No longer reacts as expected.

Previously, the RadTreeView in the left RadPane would be cut off (scroll bars appear) as the RadSplitBar was moved left. The rendered controls (IFrames, etc) in the right RadPane would shrink as the RadSplitBar was moved right. The behaviour I want.

NOW, the RadTreeView nodes, text bleeds over the RadSplitBar when initially rendered and when the RadSplitBar is moved left. It's as though the right RadPane is sliding under the left RadPane. The RadTreeView is visible superimposed over the contents of the right RadPane.

I have to revert to version 2012.3.1016.40.

Saving and Loading Resources In SharePoint List

Team,

I have implemented a radscheduler in a custom webpart. The data is stored in a SharePoint list. I get all of the fields to work and store data correctly with the example that used the LoadSchedulerData event. However, this example does not show how to properly load and save the resources from/to the SharePoint list. I have a text field called Resource added to the list. What method or format do I need to use to properly save and load the resources? Below is the event that loads the data:

private void LoadSchedulerData()
{
try
{
SPWeb web = SPContext.Current.Web;
var list = web.Lists[strAppointmentsList];
Scheduler.DataSource = list.Items.GetDataTable();
Scheduler.DataSubjectField = "Title";
Scheduler.DataStartField = "Start";
Scheduler.DataEndField = "End";
Scheduler.DataKeyField = "ID";
Scheduler.DataRecurrenceField = "RecurrenceRule";
Scheduler.DataRecurrenceParentKeyField = "RecurrenceParentID";
Scheduler.DataDescriptionField = "Description";
Scheduler.DataReminderField = "Reminder";
Scheduler.DataBind();
}
catch (Exception ex)
{
lblError.Text = String.Format("Data Loading Error: {0}, {1}", ex.Message.ToString(), ex.StackTrace.ToString());
}
}

I notice there is no "DataResourceField" like there is a "DataReminderField" so I can't assign the resource field in this manner.

(Note: I am using the trial version until we get the full version license which should be soon!)

Regards

Dan Walker

Context Menu multiple postback

I took the Treeview Context Menu demo code from here: Context Menu Demo, slightly modified it, and now when I either try to Copy or Create a new node it produces 2 nodes instead of one.
Example, right-click, choose New Folder and then get 2 instead of one. Same with Copy: What am I doing wrong here? Using the latest Chrome and IE11 as well as latest Telerik version.

RadPageLayout and IE8

There is no specific forum for the RadPageLayout so have posted here.

I found the following post... http://www.telerik.com/forums/radpagelayout-hiddenxx-properties-and-ie8

It mentions that the Responsive layout is not supported in IE8 and below but that with some tweaks it may be possible in IE8. I would love to be able to utilise this feature in IE8 as our company currently only has IE8 deployed. What are the tweaks that need to be applied.

Thanks
