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

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

Imagelist

Hi

I cannot seem to find a property on any of the command bar elements to associate it with an "imagelist". Am I missing something or can you not do this ?

I know you can add images directly but I want to use an imagelist to control the size of the images.

Thanks in advance.

Paul.

Hide cell border in child grid

I'm looking for a way to hide the cell border of a child grid in a standard hierarchy gridview. I saw posts about removing the thick border around it, but not the cell border. Is it possible?

Thanks,
Andy

Feature request: FindNodebyKey

Hi
It would be useful to be able to add nodes to the tree, specifying a key and then to be able to locate that node with a call along the lines of:

RadTreeNode node = radTreeView.GetNodeByKey(key);

Best regards

Force not check some checkbox in TriStateMode.

I want to prevent some nodes to check by some condition (let's say that is node.Enabled in this case - actually it can be more complicated).

Also I want to use TriStateMode to simplify process of control node's check state and (mainly) make visible to user that some lower nodes in tree are not checked.



In this example, nodes "Not checkable" could not be checked. And, if I check root node "Main node" - this example works fine. But when I change "block 1" and "block 2" and try to check root node - it don't. Event fired for node "Not Checkable node", invert it, return to root node and uncheck it.




Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
    RadTreeView1.TriStateMode = True
    RadTreeView1.AutoCheckChildNodes = True
    RadTreeView1.Nodes.Clear()
 
    Dim mainNode As Telerik.WinControls.UI.RadTreeNode
    Dim newNode As Telerik.WinControls.UI.RadTreeNode
    Dim newSubNode As Telerik.WinControls.UI.RadTreeNode
    mainNode = New Telerik.WinControls.UI.RadTreeNode("Main node")
    mainNode.Enabled = True
    RadTreeView1.Nodes.Add(mainNode)
 
    ' block 1 - start
    newNode = New Telerik.WinControls.UI.RadTreeNode("Checkable node")
    newNode.Enabled = True
    mainNode.Nodes.Add(newNode)
    newSubNode = New Telerik.WinControls.UI.RadTreeNode("Checkable node 1")
    newSubNode.Enabled = True
    newNode.Nodes.Add(newSubNode)
    ' block 1 - end
 
    ' block 2 - start
    newNode = New Telerik.WinControls.UI.RadTreeNode("Not Checkable node")
    newNode.Enabled = False
    mainNode.Nodes.Add(newNode)
    newSubNode = New Telerik.WinControls.UI.RadTreeNode("Not Checkable node 1")
    newSubNode.Enabled = False
    newNode.Nodes.Add(newSubNode)
    ' block 2 - end
 
    RadTreeView1.ExpandAll()
End Sub
 
Private Sub RadTreeView1_NodeCheckedChanged(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.RadTreeViewEventArgs) Handles RadTreeView1.NodeCheckedChanged
    If e.Node.Checked AndAlso Not e.Node.Enabled Then
        e.Node.Checked = False
    End If
End Sub



I am using Telerik version=2010.1.10.308



Another question: How can I maintain view of checkbox in TriStateMode? I mean that "grey sign" instead of "black sign" is not so obvious for user - I would prefer to change color or something like that. May be there is another method to control/theming checkbox? If it's possible, I would not use TriState and maintain checkboxes state (and checkbox representation) manually in code.

Icon size in RadForm

Greetings,

My application has a 48x48 icon used for a form icon and with a standard form, the 16x16 displays in the title and the 48x48 displays in the taskbar. When I use RadForm the 48x48 is in the titlebar (like the demo) and is massive. I would like to make this 16x16 in the titlebar and managed to scale using VSB, but it looks all distored. If I use a 16x16 icon for the form, the titlebar is perfect, but the taskbar icon is all distorted. Is there a way with RadForm to duplicate what the standard winform does? (displays 48x48 as 16x16 in titlebar and 48x48 in taskbar with no distortion)

Also, when I run the application the title does not appear in the jumplist for Win7 (see attached).

Thanks!

Custom RadTreeNode

Some time ago I needed to implement progress bars on my radlistboxitems which I found to be pleasantly easy to achieve. I have done similar modifications to radelement trees on a number of the other controls with no problem but I am now keen to modify the radtreeview somewhat - Only nor the radtreeview nor radtreeviewnodes appear to have a radelement tree like the others. The tree is there but it is very simplistic and with absolutely no breakdown of fillprimitives , borderprimitives and the usual layout panels combined with the standard primitives. Am I missing something ? I won't detail every change I am keen to try but one change I really "need" is to be able to implement a progressbar element on a radtreenode .
