Hello

I have found that we can allow the editor on the radtreeview level with the AllowEdit Property.

But on my treeview I have some nodes which should be editable and other which aren't.

How could I handle this ? Is it possible to prevent the initialization of the editor for some specific node ?

Thanks for you support

Hi,

I was testing the radGridView component and I was wondering how can I execute an action on double click, that is from scratch, I can see some info on the forum but its mostly particular to the post.

On my main form I fill the grid like:

        public Main()
        {
            InitializeComponent();

            grdMainWorkGrid.DataSource = WorksList.List();
        }

Regards.

Hi,

Hello, 

I need to set the fill primitive of a control programatically.  Attached is a picture of what I need to accomplish. 

From the tree on the left (of the attached image) you can see I'm setting DockLayoutPanel.ToolwindowCaptionElement.FillPrimitive to the color red.  Works great from within the designer, but I need to do it via program control.  

It seems like this control, which is in a raddock, is part of a tool tab strip so I've tried...

 toolTabStrip11.SplitPanelElement.Fill.BackColor = Color.Red;

toolTabStrip11.SplitPanelElement.ForeColor = Color.Red;

and several other variations, but none of them changed the color.   Is there a way to do this grammatically? 

Thanks to anyone who can solve this, 

Steve

Hi,

I am facing an exception when using excel-like filtering in RadGridView and use "Null" and some other value for filtering. The details is given below.

My system information,

• OS: Windows 7, 64 bit
• IDE: Visual Studio 2013
• Language: C#, .NET 4.5
• Telerik version: 2016.1.216.40 (2016 Q1)
• Telerik Runtime version: v4.0.30319

Steps to reproduce the exception

1. Create new Telerik Windows Forms Application
2. Add Telerik.WinControls.GridView as reference
3. In the generated RadForm add a RadGridView
4. Add a text box column to the grid view
5. Enable excel-like filtering in the grid view
   • radGridView1.EnableFiltering = true;
   • radGridView1.ShowFilteringRow = false;
   • radGridView1.ShowHeaderCellButtons = true;
6. Run the project
7. Add 4-5 rows with any values
8. Edit at least one row, clear the value and press enter. This will make the value "Null" and "Null" will become available in filtering
9. Press filter button and select "Null". This will uncheck all other filters
10. Now check any other value excluding "Not Null"
11. The exception is thrown, here's the stack trace -

Looking forward to a quick solution for this.

Thanks and Regards

Hi,

I am trying to set the backcolor of the DateTimePicker and TimePicker when disabled. I am already overriding the OnEnabledChanged event to replace the TextBoxElement with our custom text box so I can update the forecolor and this is all working OK and the backcolor of the textbox is correct, however the control border, dropdown arrow, etc. are still using the old color and I am unable to work out what properties I need to update to access these items.

How do i update the backcolor of all of the visible items for the entire DateTimePicker and for a TimePicker?

Thanks,

Mark.
