[Solved] Dock Tab style gone after Upgrade

I just upgraded to Q1 2010 SP2 and our Dock tabs have lost their old style. They were nice blue rounded rectangular tabs that matched the rest of the app before the upgrade but now they are slanted on the side, black n white, and are no longer wide enough for the text. How can I keep the upgrade but get these tabs to look as they once did? Thx...

Is Microsoft.mshtml.dll an included reference?

I am having an issue with deploying my application.

This is my first application using RadTools and the first time i've ever seen this problem.

So I was curious if the tools had this file included.

I do not have this file in my References, so I wasn't sure why its causing an error.

thanks!

my error:

System.NullReferenceException

I have a form in a WindowsApplication with just a RadTreeNode on it.

    
            Imports System  
        
            Imports Telerik.WinControls.UI  
        
            Public Class Form1  
        
                Inherits Form  
        
                Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load  
        
                    InitializeComponent()  
        
                    Dim node As RadTreeNode = RadTreeView1.Nodes("Email Contacts").Nodes.Add("Bob Tony")  
        
                    node.Selected = True 
        
                    RadTreeView1.Nodes("Email Contacts").Nodes.Add("Sue Winchell")  
        
                    RadTreeView1.Nodes("Email Contacts").Nodes.Add("Lui Sang")  
        
                    RadTreeView1.Nodes("Lists").Nodes.Add("Priorities")  
        
                    RadTreeView1.Nodes("Lists").Nodes.Add("Opportunities")  
        
                    RadTreeView1.Nodes("Lists").Nodes.Add("Issues")  
        
                End Sub 
        
            End Class

This is from your example.
On reaching this line:
Dim node As RadTreeNode = RadTreeView1.Nodes("Email Contacts").Nodes.Add("Bob Tony")
I keep getting the error:
System.NullReferenceException was unhandled
Message="Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt."

What's happening and how do I correct it?

Thanks in advance
Karl

CellElement null

Hi,

I have problems with VS2010 and the newest Version with the GridView. I can't set the Font and other properties, because the CellElement is null. The same code works with VS2008 and the GridView from the last year.

Is that a known problem?

Greetings

Konrad

private void radGridView1_ViewRowFormatting(object sender, RowFormattingEventArgs e)

{

...
...

e.RowElement.GradientStyle =

GradientStyles.Solid;

e.RowElement.RowInfo.Cells[

"Nr"].CellElement.Font = _einzelRingFontNr;

e.RowElement.RowInfo.Cells[

"Ring"].CellElement.Font = _einzelRingFontRing;

e.RowElement.RowInfo.Cells[

"Teiler"].CellElement.Font = _einzelRingFontTeiler;

e.RowElement.RowInfo.Cells[

"Pos"].CellElement.Font = _einzelRingFontPosition;

Problem using desert theme on treeview in Office2010 themed app

Hi All

I have an app using the Office2010 theme.

But we prefer the desert theme for our tree view. I used this code to force the theme

        private static void ForceTreeviewTheme(RadTreeView tv)
        {
           // tv.EnableTheming = false;
            tv.ThemeName = "Desert";
            tv.RootElement.ForceReApplyStyle();
            tv.RootElement.ForceApplyTheme();
        }

It worked ok but the node back colours were still Office2010 grey and I cannot see the node selection colour when I click and select a node.
If I do not disable theming or re-enable it I get the Office 2010 theme again, making me think I have not actually applied the theme at all!

What is the best way to achieve this goal?

Thanks

Problem with rows when filter is active

Hi,

I am filtering a checkbox column. When Filter is active, logically, only rows, which the checkbox column accept the filter criterium, are shown.

The problem is..., ¿where are the rest rows??? ¿Where are the rows which aren't shown?

Only a checkbox can be active. The checkbox column can not have two rows with the checkbox cell set to true.

Then, when the user click the checkbox and the value is true, I programaticly find in the all gridview's row and find the other row whose checkbox cell is true. I set this cell to false. This works fine.

The problem is when the filter is active, if the filter is filtering the checkbox column when the cell is set to false, when the user set to true the row, I can not find the other row whose checkbox cell is set to true.

¿How do I this ???

I am thinking not permit to the user edit rows when filter is active. But..., ¿How do I know when the filter is active?

Thank you,

Fernan
