Hi,

I'm having problems with binding my items within a gridview controltemplate. I've already followed the WPF examples of it (GridView Examples - Appearence - Custom Row Layout), but whatever I try, binding isn't working when the RowStyle/ControlTemplate is active.

Below a simplified code snippet from the example, but with my own binding names:

You see the bindings to Data1, Data2, Data3, but as soon as I run it, those field stay empty, see screenshot 1

However, when I remove the RowStyle="{StaticResource rowStyle}" in my RadGridView then the Data is displayed correctly in the row, see screenshot 2

I've already tried binding with Path=, or CurrentItem.Data1 and several other options, but none of it works, while it works in de example.

I'm problably missing something, but if I compare my code with the example, I don't see any difference in binding, so any help would be appreciated.

Thanks in advance

Hi,
    I am relatively new to WPF and Telerik RadGridView. I have a requirement to validate my cell column in heiarchical gridview in WPF. Means suppose when the user clicks on the column and enters a value, we should be able to check the db and validate whether the data entered is right or wrong and show proper messages. I am using WPF with MVVM and EF. Can you please suggest me the best possible way to achieve this functionality.

Thanks & Regards

I have some data that is coming from a Stored procedure which i have been able to display in a non-Telerik DataGrid.  using the following code.


But with using the radCartesianChart, It says that there is no ItemSource.
So How do i load the chart with Data?

I created a test project and used the Metro style resource dictionary provided with the WPF tools to create the look for our project's scheduler.  However, moving the style over to the main project, none of the visuals are working--Drag & Drop time markers don't appear, nor does a mouse-over for the cells indicating which cell you are on.  Resizing appointments also lacks visuals.  It's like the scheduler is completely static in terms of visual cues.  Unfortunately I haven't been able to reproduce this in a sample project, and our main project's code isn't practical to post.  I'm hoping someone has encountered this and can offer some suggestions. I've attached a screen grab showing the setup of our day view just to add a little context.

Hi,

I have stantard MVVM scenario, when I exposed ReadOnlyObservableCollection as a public property on my ViewModel. I add or remove items by commands, because it involves additional domain logic. I dont want to make the source collection public to ensure consistency of my model.

In treeview I solved it nicely with PreviewDragEnded="RadTreeView_PreviewDragEnded". 
How to do it with RadListBox?

Thanks.

Hi,

Im trying to use RadRichTextBox together with the Ribbon control to get a Word-like text editor in my application.

So far I've initialized the editor with some content, which can be either plain text, RTF of HTML, so I used the different format providers and its working like a charm.

Now I want to be able to insert content at the caret position. For inserting plain text, I'm using the Insert method, and its working fine, but how do I insert RTF and HTML? On top of that, the inserted RTF or HTML should keep its original formatting and style.

Let me start this with, I am using the Q2 2012 version and this is my first attempt at using this control...

I am trying to use the pie chart to render data from database based on the dates entered by the user.  The user can reset these dates at any time and in which case I need to update the pie chart based on the new dates.  I have done this by setting up events and when the user enters the date, then I will refresh my pie chart data.

Problem 1) So at first I figured the easiest way to do this would be clear the points and re-add them.  However, this would throw an error stating index out of range.  In debug this was looking for the PieSeries.cs file.  You can reproduce this by displaying some data and then on the click of a button call pieChart.Series[0].DataPoints.Clear().  I can provide a call stack if necessary.

Problem 2) I then went back and added all the required datapoints in xaml and gave them a name.  I then changed it to use those named points and reset the values.  Now when I update the values and the labels, the chart itself is not updating.  Is there some call to tell the chart to re-evaluate the values?

Problem 3) When the user selects a date range that does not contain any data to be displayed, I need to update the chart to reflect this.  I currently set the points value to 0, but it doesn't update to reflect 0 values.  What is the best way to accomplish this?

Problem 4) When the user is hovering over a slice in the pie, I want to either be able to "explode" that slice or at least update the tooltip to reflect some other internal data.  I noticed in posts from the past that the "explode" event was ready, but is it ready now?  If so then what is the event?  If this event is not there then could you at least tell me how in the TooltipOpening even I can get the datapoint that the mouse is currently hovering over?

Thanks in advance for your time and efforts.

Hi All,

I am having 15 columns in my RadGridview. In the UI it shows 10 columns to see other 5 column i have to scroll horizontally. When i reorder the column,horizantal scroll bar is not scrolling some thing like in the screenshot. Is there any way to enable the horizontal scrollbar to move when i reorder? Please advise me on this.

Check the screenshot below :

Hi,

For many properties I often initialise the underlying field in the get accessor. ie
But binding "SelectedItem" to this property crashes the program when I start typing. If I remove the initialisation part, it works. ie:

Was this a design decision with RadAutoCompleteBox or a bug? I've never had this problem with any other telerik controls.

I would like to have the gridview paging size dynamically adjusted when gridview height changed, so that the grid would not have any void, nor would user require to scroll up and down.

I handled the gridview's SizeChanged event and tried the following code:


It pretty much worked, except when the column header is visible, as it the taller than the row height, the above calculation is not exact anymore. It also doesn't handle when horizontal scrollbar is visible.

Is there a better way to calculate the number of rows that should be visible?
