RadTabControl has bug, by default it make their content controls like (TextBox, ComboBox) shows raedonly non editable in running mode for RadTabItem.

Only CheckBox control can be editable when used with RadTabControl otherwise TextBox and ConboBox are behaving like non editable readonly controls when hosted into RadTabControl

HI,
i download the trial of WPF controls, but with this release of the framework don't work.
Can i use this control with the SP1 of the .Net Framework?

Thank's

I have tried RadTabControl for data entry Form, where I am facing problem with controls like TextBox and ComboBox once added it for RadTabItem then in running state those controls are always showing in readonly(Non editable) mode by default. Please provide solution for this.

Hi,
I just started playing with the RadDatePikcer and overall it looks very good. I have only few comments at this point:

1. The control needs to provide the input mask for the user. Currently control allows any input and will not prompt user if it's not valid (it is simply discarded)
2. The zoom animation shouldn't play when drop down is expanding. It also plays when calendar is used as standalone control and I belive it should play only when user makes action.
3. Provide control descriptions that would show in toolbox in blend.
4. Support IsReadOnly property so the user can select and copy value but can't change it.
5. Add support for time input. The time picker would be nice but control should at least alow to enter time manually.
6. The drop down button in the default skin should be changed to look the same like in Vista: this means the down arrow with a calendar icon. The button shouldn't be a TabStop either.
7. Dropdown changes width when swiching from month view to any other view.
8. Add today button in the drop-down (optional).

This is all I found so far.

Thanks for the great work and I'm looking forward for the next release.

Hi,

 I installed the trial version of WPF. Started C# Samples and clicked on RadGridView --> First Look and clicked on one of the menu items in the left.


I got the following error

Failed object initialization (ISupportInitialize.EndInit). I have the screenshot but unable to post it in the forum.

I'd like to hear, if and when , are you going to add the popup autogenerated edit form to your wpf grid.
One of the best feature of the ajax asp net grid,  is a must have for the wpf grid.

Thanks

Hello,

I'm facing some problems with CurrentRecord. I'm binding the object with CurrentRecord. I can't get the currentrecord from the code where I keep the object.

Error: Put the breakpoint in setter of ActiveRecord in ViewModel. That property will never get called.

You can download the test project in the comment of this post..

http://michaelsync.net/2008/08/09/any-recommendation-for-wpf-datagrid

Note: I think that there is a wrapper for data object in your datagrid. so, I think it might be the reason why it's not working. maybe, I think I need to call DataWrapper.ActiveRecord or something...

PS: Thanks a lot for visiting my blog,  Hristo!

I have three-levels grouping in GridView.

I would like to specify the different style for different level for GroupRow. Is it possible to do that?

For example
-AAA (GroupRow)
-----BBB (GroupRow)
----------CCCC(Normal Row)

I want to set as below.

- Set blue color to AAA GroupRow.
- Set Yellow Color to BBB and put Textbox called TextboxLevel2 in style
- Set Pink color to CCC and put Checkbox in normal rows.

Is it possible to do that with Telerik Datagrid? Can get the value of TextboxLevel2 at runtime?

I'm reading Styling in Expression Blend from RadGridView Doc. I found that Edit Other Templates is disabled in Blend, why?

Thanks in advance.

Hello,

There is a feature that I never see in other chart products, for example I got 4 array of results and wants to see dynamic evolution between them.

In RadChart there is animation when it is rendered, but I mean something like a slide with my arrays and animation.
Maybe it is already there and I missed this feature.

Thanks !
