Hi, please see images below and let me know if this is something that has been mentioned before.

When we first load our grid none of the columns are shown - see first screenshot (a).

After repopulating the dataset (ObservableCollection) with data, the columns are still all shrunk/collapsed - second image (b).

The blue column size stretcher has to be dragged to the right to reveal all the columns - third image (c).

It looks like it may be due to the container, Grid being set to * Width as we want the grid to fully populate the right of the screen, is there a way round this to have the radgridview work in this manner?

 

 

Hello,

I've replicated, at least, this error when using the List view: when file names are too long, they are truncated (with ...) and there is no way to widen the field. This is very annoying when files with similar long names are displayed in the control.

It's also different to how Windows Explorer works.

Regards

I need to make a polar chart that is not labeled 0 to360 but 0 to 180 and 0 to -150.  Any ideas on how I might do this?

I included an image of what I need in case it is not clear.

Hi，

I just created a RadRibbonWindow in my application, each time I called this window,the program was interupted. 

Picture of exception is in attachment.

 

These are my codes in xaml:

            <telerik:RadRibbonTab Header="View" />
        </telerik:RadRibbonView>
    </Grid>
</telerik:RadRibbonWindow> 

 

Backstage codes are original.

 

Does anyone know what causes this problem?I've tried everything I know,like remove and re-referencingTelerik.WIndows.Controls.Input.dll.

Thanks alot!

I have a RadGridView that I want to keep its structure but add some button of my own at the end of each line.

<telerik:RadGridView Grid.Row="0" 
                     ItemsSource="{Binding MyList}"
                     RowIndicatorVisibility="Collapsed"
                     AutoGenerateColumns="False"
                     FrozenColumnsSplitterVisibility="Collapsed">
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding A}" Header="A"/>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding B}" Header="B"/>
    </telerik:RadGridView.Columns>
</telerik:RadGridView>

 

And for example, I want to achieve that:

Is there a way to use SVG/XAML (vector) icons in ApplicationButtonImageSource  and in the RadRibbonBackstageItem entries ?

I am able to set the Icon field in RadContextMenu to <Path  Data="....Vector info..."/> and use vector graphics - would like to do the same for the icons in the RibbonView.

Your help is much appreciated.

Hello, I'm in front of a mystery.

I have 2 columns, created dynamically in a RadGridView. Let's name them column A and column B.

When I have one row, and I select a cell in column A, then click on column B's header to sort it, SelectedCellsChanged is fired and args.RemovedCells contains my cell. From this, I understand that I lose my selection when I sort a column, which is perfectly fine.

When I have two rows, and I select both cells in column A, then click on column B's header to sort it, both GridViewCellInfo have their .Item to null in SelectedCellsChangedEventArgs.RemovedCells, which is unexpected on my side!

That way, I can't identify the rows to which these removed cells belong, which is painful.

Why is that?
Thanks!

This is more to any Telerik support people on the forum...

I am working on resolving an error in a Windows application that we use.  The application was originally written back in 2012 (and last updated in 2016) using Visual Studio 2010 with and C#.  Also, we are running it under Windows 10.

When debugging the source code, the underlying exception that I see is

System.NullReferenceException: Object reference not set to an instance of an object.

....

and uses an older version (2012) of the Telerik UI for WPF library (I think that is the one):

I found the following forum post

https://www.telerik.com/forums/unhandled-exception-telerik-windows-automation-peers-gridviewgrouppanelautomationpeer-getchildrencore

and wanted to try the latest version of either the 2012 (I don't know if we have those) or 2013 (depending on how much the API changed) libraries.  The issue with doing so is that (so far, still working on that) I can't find anyone here with any knowledge of an existing Telerik account or past account from which I can get the older libraries.  Would I be able to get those without having an account, at this juncture?

Thanks for any assistance in advance...

We are trying to create a global TaskManager to cancel all tasks as a user navigates if the load is still taking place. We use QueryableDataServiceCollectionView across many grids in our system to support all the filtering, paging, and grouping. I can call the method that sets the collections query and context and to auto load it but the loaded method is never called. Is there a way to use a task to track the progress of the loading collection?

Aside from just turning it off, is it possible to make it position itself intelligently? It likes to position itself at the top of the image regardless of whether that is actually within the bounds of the RichTextBox. Additionally, it stays on top of everything, which is disconcerting when you switch to other applications.
