Hi,

we are in a process of upgrading telerik dlls periodically.

prevoiusly we are using 2009.3.9.1203 version dlls.
here we are able to add check box in the header of a RadGridView using "CheckBoxHeaderCell" class which is given in the telerik forums.
here we are not creating a checkbox column and adding it to RadGridView instead we are are getting bool values from DB and binding them to RadGridView and we are just adding Checkbox in the Header.

when we upgrade the telerik dlls to 2010.2.10.806 version we are not able to add check box as we did above.

i found some sample code in telerik forums which gives code to add the checkBox column with header.

Is it possible to add check box in the header with out creating the entire check box column
here my check box column is displayed with the DB values and i just want to add check box in the header and handle the event.

if possible please give sample code.

Thank you,
Shashi

[Solved] ComboBoxColumn automatic creation

Hi,

how could I make a grid automatically create a ComboBoxColumn by giving it a BindingList of custom objects? The grid only detects decimal and datetime columns corresponding to object's properties of the same type, but for the remaining properties it creates TextBoxColumns. This is correct because these properties are string but the column's type should be ComboBoxColumn. I'm guessing if there's a way to change the column's type dinamically, but the explicit cast produces an exception.

Greetings,
Giovanni

Drop a simple text into a RadTreeView - Visual Indicator Problems

Hi,
I need to drop a simple plain text from a textbox into a Rad Treeview.
I just read the forum, I'm mixing OLE Drag & Drop and RadTreeView Drag & Drop. The Events seems to be right and they seems to work fine.
But I'm just having a problem with the Visual Indicators of the treeview.

When I drop a regular node inside the treeview, I can see that visual indicators (the target node is highlighted, I can see a line of dots showing the direction above or below the target node, the "forbidden" cursor, etc).
And when I actually try to drop a simple text inside the treeview, I don't see any of those stuff.
I need the same visual behavior when dropping a simple text. I need to see the indicators and I don't know how to activate them.

I will appretiate the help.

Thanks!

Must Type Alt Key 2x vs. 1x to Activate RadMenu Starting w/ 2009Q3

1. I just installed Telerik Q3 2009 WinForms (2009.3.9.1103) over Q2 2009 (2009.2.9.729) and it's now requiring you press the Alt Key twice before the RadMenu will activate.

2. I noticed your Q3 2009 Release Notes for RadMenu says "RadMenu can now be highlighted via system keys (alt and F10)". It was already (in Q2 2009) allowing itself to be "highlighted" via the Alt key for me and I had nothing explicitly implemented (i.e. via any KeyDown Events) to make that happen. Am I missing something?

Telerik WinForms 2009Q3 (2009.3.9.1103), VB, VS 2005 (v8.0.50727.762 SP.050727-7600), .Net 2.0 (2.0.50727), XP SP3, 3GB, 2.99GHZ, Core2Duo.

[Solved] Refresh in data binding issue.

Hi,

Description:

I'm facing refreshing issue when using rad grid view (below I've attached code snippet you can use to reproduce it).

Generally in the described example I have two collections in parent - child relation binded to grid view and one button that adds new object to child collection.

Problem:

When first node in grid is expanded and have no children and I add a new child, it won't appear in grid view, even that node is marked as expanded (untitled.png). To see it I have to collapse and expand it again (untitled2.png) .

It's very imported for me to make it working correctly.

Code:

002.using System.Collections.Generic;

003.using System.ComponentModel;

CheckBoxColumn filter always showing

Hello

We recently upgraded to verson 2010.3.10.1109 and after the upgrade noticed that a GridView that we have with a CheckBoxColumn is always showing the checkbox in the filter row. I have confirmed that AllowFilter is false for the given column. Is there a workaround for this issue?

Thanks

DateTimePicker - Overview and Getting Started

Good Day,

I thought I'd just let you know that the in the documentation for the WinForms Q3 2010 SP1 documentation the RadTimePicker Overview and Getting Started is incorrectly shown. On the overview page it shows an image of the Treeview control and on the Getting Started page it shows the Visual Style builder screenshot with a button.

CommandBarStripElement Missing Properties

Good Day,

I've got this problem where I cannot see the Grip Properties or OverflowButton Properties for the CommandBarStripElement in the VS.NET IDE with the new Telerik Q3 SP1 Control set. I use to be able to set the visibility properties of both the Grip and OverflowButton using the VS.NET propertygrid. I know I can do this from the code-behind please let me know if I'm just losing it.

Please see link to image below.
