RadDropDownMenu

Hi, I'm working with two monitors. When I move the treeview to the secondary monitor, the context menu of every node is displayed in the main monitor. It occurs too with the control demo installed with the components, so, I suposs that it's a bug.

Another thing, text displayed in the context menu are not aligned. I change every TextAlignment of each item, but what are displayed at runtime is very different.

Thanks.

Radiobuttons not working together

Hi
I have placed a RadTreeView on a form and then in the load event have the following:

    
                        for (int i = 0; i < 10; i++)  
        
                        {  
        
                            RadTreeNode treeNode = new RadTreeNode(i.ToString());  
        
                            treeNode.ShowRadioButton = true;  
        
                            radTreeView1.Nodes.Add(treeNode);  
        
                        }

The problem is that when I click on one item in the list and then another, the first one is not deselected and I end up with all the radio buttons selected. The sample you provide does not have this problem.

Please could you explain how to achieve the effect I want - a list of (top level) radio buttons.

Thanks

Best regards

Marek

Self referencing tree

Hi.
I am using the Rad Treeview for Win Forms.
I am trying to bind the tree to a datatable.
The table consists of columns that include ID and ParentID
However, the ID and ParentID are GUID's. Am I correct in assuming that the columns need to be integers? As the binding is giving me weird errors (Unable to cast object of type 'System.Windows.Forms.RelatedPropertyManager' to type 'System.Windows.Forms.CurrencyManager'.)

What do you suggest I do to fix this? Is my only option to go and create a method that will loop through each of these rows in my table and convert their GUID's into integers and match up the related ParentID's?

Thanks for any help,
Kris

RadTreeView - Binding to Custom Business Objects

Has anyone been able to get a RadTreeView to bind to custom business objects?
I followed the example in the help but it only seems to show my first level artist nodes. In fact it doesn't even show the top level 'Artists' node.

I was also initially getting null object errors adding to the RelationBindings collection. It seems the collection is not initialized until you call some other method like RadTreeView.DataSource.

The example also only seems to use a single binding source and then uses compound property references to navigate the sub-relationships e.g. "Albums.Songs", whereas the DataSet example sets up a different binding source for each type of data.

Also assuming I could get this to work, what is the liklihood that it will be two way. I tried editing the name of a top level node and that seems to push the name back into the source data object. But what will happen if I start dragging and dropping. Is it to much to expect that it will handle this too? I guess that would be problematic for the Artists/Albums/Songs example because you could drag a Song to an Artist. However, I have a need for a generic type hierarchy where all nodes are the same type and so a node can be dragged pretty much anywhere.

Thanks for any input
Martin

[Solved] Populate with class objects

Hello,

I'm converting over to telerik controls from straight ms objects and I'm running into a problem with drop down lists. I have a simple class that I created for date selection and I currently use this in my project with combo boxes. With a regular combo box I am able to add the objects right into the combo box, however I don't see that with the rad drop down list and I'm unsure the best way to get the same functionality.

If it helps, the object has a text value and then 2 dates. It's used for a 'quick date' selection, so the drop down has items like "Today", "This Week", "This Month" etc. and when the user selects the item they want I can use the object to get the 2 dates that are attached to the object and filter my data.

Thanks for any help you can provide!

RadMessageBox cursor focus

Hi,

I display RadMessageBox in a textbox's validating. After I press OK button in the messagebox, the cursor is focus in the current control instead of next control.
However, if I use Visual Studio's messagebox, the cursor will stay in the next control after I press OK button.
So, how can I solve it?

p.s. The step to produce this problem as following:
1. Click on TextBox1 in form
2. Tab away from TextBox1
3. Message prompt out.
4. Use mouse to click [OK] button in message box.
5. After the message box disappear, the cursor stay in textbox1 (it should stay in textbox2).

Imports Telerik.WinControls

Public Class Form1

Private Sub TextBox1_Validating(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles TextBox1.Validating

RadMessageBox.Show("Testing", Me.Text, MessageBoxButtons.OK, RadMessageIcon.Info)

End Sub

End Class

[Solved] Multi-edit column values for selected rows

Hi,

I want to use the mouse and select multiple rows in one column or use "Shift-select" a couple of rows.
When I release the mouse (the mouse_up event triggers) I want the selected cells to be editable or maby one of the cells.
When the new value is entered in the editable cell and I hit the Enter button, all marked cells should be updated with the new value.

Is this possible? In that case how?

Thanks!!
Ola
