I have used Panorama in my existing application. I have added 3 tiles of colspan 2 in 4 rows(3 in each row). In the 4th row as i made colspan of one tile to 3.Now the tiles which are closed to border of tile group are not clickable. I have faced this issue even by changing the tiles setting. But if i increase the width of the Tile Group and Panorama the tiles becomes clickable. So the issue in short is the tiles close to the tile group are not clickable.

I have been unable to resolve this for many days. waiting for your reply

Better way of making columns visible invisible

Hello

I have 74 columns in my grid view which a user can choose to view or not using the column chooser.

On first bind of the grid it leaves about 10 of these visible but makes the rest invisible, this is making the startup of my windows app incredibly slow.., to the point that it sometimes crashes..

I know 74 is a huge amount, but this is a business requirement to give the users the option.

Is there anyway of doing this using the grid view and column chooser without it being so incredibly slow, or do you have any suggestions of another method I can use?

Thanks

Becky

radtreeview drag

Hi,

I'm trying to drag a radtreeview node into a radtextbox. I just want the information stored in the node "ToolTipText" to be displayed in the radtextbox.I did the following:
1. Set radtreeview AllowDragDrop to true
2. Set readtxtbox AllowDrop to true
3. In order to block radtreeview nodes to be moved in the tree I implemented a "DragEnding" event:

private void treeview_DragEnding(object sender, Telerik.WinControls.UI.RadTreeViewDragCancelEventArgs e)

{

e.Cancel = true;

}

4. I also implemented a "ItemDrag":

private void treeview_ItemDrag(object sender, Telerik.WinControls.UI.RadTreeViewEventArgs e)

{

DoDragDrop(e.Node, DragDropEffects.Copy);

}

5. In the radtextbox I implementeded the following "DragEnter" event:

private void textbox_DragEnter(object sender, DragEventArgs e)

{

IDataObject dataObject = e.Data;

if (dataObject == null)

e.Effect = DragDropEffects.None;

else

{

Telerik.WinControls.UI.RadTreeNode Node = dataObject.GetData(typeof(Telerik.WinControls.UI.RadTreeNode)) as Telerik.WinControls.UI.RadTreeNode;

if (Node != null)

e.Effect = e.AllowedEffect;

else

e.Effect = DragDropEffects.None;

}

6. I also implemented the "DragDrop"event for the textbox:

private void textbox_DragDrop(object sender, DragEventArgs e)

{

IDataObject dataObject = e.Data;

if (dataObject != null)

{

Telerik.WinControls.UI.RadTreeNode Node = dataObject.GetData(typeof(Telerik.WinControls.UI.RadTreeNode)) as Telerik.WinControls.UI.RadTreeNode;

if (Node != null)

textbox.Text = textbox.Text.Insert(textbox.SelectionStart, "Ok");

}

the problem is that the opration is not working. When I move a node over the radtextbox the program frozes. I used the VS "debug | break all" menu option and the stack has a lot of "_ItemDrag" event calls.

Any ideas?

Thanks,

Francisco

Check if appointment intersects with other appointment

Hi all,

How can I check if an appointment intersects with an other appointment?

I'm using the radscheduler for a planning tool. I'm using recurring appointments to determent the work scheduler for the employees.
But I can't figure out how to check if the appointments intersects with the recurrencerule of the appointments.

Edit
I also would like to know how I can add an appointment for every resource. This specifically for the holydays (Christmas for instance)

greetings

Data Form Control

Hi Telerik Team, In Radcontrols for WPF and for Silverlight there is a Dataform control. Is there something similiar in Radcontrols for Winforms as there is a Formcontrol? Is there a sample available? Or do I have to create the control or form myself? Thank you. Kind regards, Joerg
