Hi,

I am using Treeview to show a recursive data structure. I would like to get the item when mouse is over, process the value of the item and show tooltip.

How can I get the item?

Thanks,

                    only the edit column and the campaign name column details are visible when we select the checkbox, the rest of the columns which are like 21 columns are hidden,

please help me out on this issue as this is important to the client.

thank you for your help in advance.




               

In code like this...

How do I set the "title" property of the group? I need to simulate the grouping of a column named “Parent” – as far as I can see I cannot mark a column as a default grouping set so I need to do it programmatically. However when I do it this way the resulting item in the group header says “CmsPageParent.Title” not “Parent” as the header for the same column would.

Ideas?

How do I install the trial version of WPF into VS2008?

The .zip file contains a Bin3/Documentation/Demos folders, but I can't find an installation file.

I can't seem to locate any help file to assist.

Thanks.

Getting used to the impressive speed and ease at which we can create a brilliant interface with the telerik winforms controls , I find myself wondering about WPF.

WPF is awesome in terms of flexibility and customisation capabilities. It's awesome in terms of performance too. Because of that , all I saw in my mind of the WPF versions of the telerik controls was just winforms x 10.

But we get to the new release of the second beta of the eagerly awaited Q3 release and while the new ribbonbar is as great as expected , it's a far contrast from the winforms one. Suddenly the gap in designer capability differences in what microsoft provides for wpf and winforms becomes exceptionally painful.

Doing a simple ribbonbar is suddenly a ream of code and by no means rad. :/ So all of a sudden when the complexitiy of controls goes up (and let's face it one of the strengths of wpf is in the ability to easily build complex/layered controls) then suddenly it becomes MORE time consuming to create these controls.

So I suppose my point is the concept of xaml is lovely when the complexity of the controls is below a certain level , in fact at that level or below you can create more complex controls than winforms with much less code and time investment. But past a certain point , the code and time investment needed is far greater.

I love the new WPF ribbon bar but creating a ribbon feels really tedious not to mention that once complexity builds on the ribbon , parts of it just don't feel or look intuitive at all. Right now I would dread developing a serious ribbonbar for a serious application and then needing to do even simple changes to it.

Anyone else feel like microsoft are really slacking with wpf designer capability ? Or am I just missing something ?

I have two tables having one to one mapping :
for instance:
1) VEHICLE_DATA:Vehicle_type,termleased(columns)
2)VEHICLE_TYPE:Vehicle_type,vehicle_name,Owned

Now I am having IList<VEHICLE_DATA>(having VEHICLE_TYPE property) list  which I m binding to Gridview
radGridView1.ItemsSource=list;

and in Xaml in one of the column of grid I am specifying {Binding Path=vehicle_name}
It doesn't give any error,but doesn't display vehicle_name in grid.

Please help me for this ASAP.

Using the gridview setup below...

• The simple column (Title) acts as you would expect, it can be grouped by, sorted and fitered
• The complex rows (Paren and Status) canot be grouped, sored  filtered.This looks like a bug in the grid
• If you set the grouping manually, you can group by the parent column, however the grouping is NOT re-parsed when the data updates... this is another serious flaw

Any help?

Dear team,

I have a problem when setting the IsDropDownOpenProperty on a RadComboBox, Yes, I know there's a similar post (that I've read) but that did not help me to solve my problem. ;)
I have a RadGridView, where the CellEditTemplate of a given column must change at runtime, depending on the type of row that is currently being edited.
So I have an event handler at the RadGridView SelectionChanged event, that determines the type of row (meaning the type of data we have inside it), and then dinamically builds a DataTemplate that is assigned to the grid column.
In one particular case, this template is a RadComboBox with a set of available values, and the core instructions that build this template are the followings:


Everything worked fine, until I introduced the 4th dependecy property, which is RadComboBox.IsDropDownOpenProperty because I clearly wanted the combo box to be displayed already opened.
The template is built correctly, but this gives me an error when it is going to be instantiated into my RadGridView's column.
The exception details are:

 (a bit long, sorry ... )

If I comment out the faulty line, the DataTemplate is instantiated correctly, and I can see my combo box in the RadGridView, but it is obviously closed, which is not fine for my case.
I also tried a similar, parallel case, where I replaced the RadComboBox with standard Windows WPF ComboBox, and I was surprised that I can use the ComboBox.IsDropDownOpenProperty without any problem, and the ComboBox that is built, is shown already opened just like I wanted it to be.

I would be happy to use a workaround also, to fix this.

Thanks a lot for your effort and do not hesitate to ask me any further information that may help you.

Kind Regards.

Max.
