Hello,
I've implemented a multi-select ComboBoxColumn using checkboxes as follows:

Everything works great except I'd like the user to be able to select the checkboxes using the spacebar.  How can I achieve this?

Thanks in advance..

Hi,

We are currently using a RichTextBox to display simple HTML content.

To style the content, we are using this code:


However, this leaves list icons and list numbers without a style applied: http://i.imgur.com/rbwx4.png

How can I apply a default style to those elements too?

Thanks.

Hi,

We have a RadGridView with some custom column implementations, changeing the original value bound to this columns. Now we have the problem, that the default sort mechanism sorts the rows with the original values from the data source, but it should be sorted with the displayed column values. I also can not use the expression sort descriptors, I have no access to the displayed type at compoleing time.

Is there a way to change this behavior?

Thanks for help,
Michael

Hi,

I tried adding and event trigger on my GridViewDataColumn but it doesn't seem to fire the command.


Is it actually possible to add event trigger to GridViewDataColumn?

sorry new to WPF
i'm having trouble understanding how to load the RadDiagramToolbox from codebehind with the standard shape.

Any help is greatly appreciated

I have a column

       <telerik:GridViewDataColumn

                    UniqueName="CarrierCommission"

                                  DataFormatString="c"

                                  IsVisible="{Binding Path=SearchCriteria, Converter={StaticResource CarrierColumnConverter}}"

                                  Header="{StaticResource CarrierCommission}"

                                  DataMemberBinding="{Binding Path=CarrierRepCommission}"

                                  Width="{StaticResource CommissionColumnWidth}">

        </telerik:GridViewDataColumn>

I would like to programmatically refresh the IsVisible property by calling UpdateTarget on the IsVisible binding expression.  However, it seems that no matter when I call

 

Dim exp As BindingExpression = column.GetBindingExpression(Telerik.Windows.Controls.GridViewDataColumn.IsVisibleProperty)

I always get null for the value of exp.  When is it safe to call GetBindingExpression or is there another way to refresh the binding.

Thanks,

Hello,

I"m having some troubles. I'm using this VirtualQueriableCollectionView with a RadCarousel. It's working well up until i change the VirtualItemCount in the ItemsLoading event. 

little more information:
We're using this VirtualQueriableCollectionView to load only a portion of the entire file. that part is working great.
On this control we have a TextBox that we use to search each column. unfortunately we're not using sql so we need to read each record and check the fields to see if any of them mach the TextBox text value. Doing it this way we wont know how many records we have in total so when we're finally done searching all of the records we will have a total count of records that match the textbox value and we'll need to change the VirtualItemCount in the ItemsLoading EventHandler. Now when i change the VirtualItemCount in my test wpf application it works just fine. But when i change it when it's hosted in WindowsForms (our main app is using winforms) I get "Collection was modified after the enumerator was instantiated.". 

I'm curious if you have any ideas of how i can work around this issue?

I hope that makes sense. If you need more information please let me know. I can hook you up with a test application too if needed.

Thanks Much,

Hi Team,

I have purchased the telerik licences  recently. I am using  RadBooK control for showing PDF file as needed the functionality  to change the pages horizontally(Swipe functionality).
But my requirement is also to have Zoom in/out and Panning feature by touch(and multi-touch also).

Please guide me for achieving this functionality. It will be great if you can also provide Code snippets or relevant links.

Thanks,
Mandeep Kaur. 

We have a gridview.ItemSource = datafilter.FilterdSource and the datafilter.Source = datatable.DefaultView. When we (manually) generate the columns they are type of GridViewColumnBase and the columns to be updated are of DataType System.String. The gridview is set to readonly and we set some values in the background depending on user actions. Generally the action is based on a context menu click and we are accessing the record as (gridview.Items[i] as DataRowView). We then set the value of the cell by the column name and it works great but sometimes it will give us an exception saying the column 'x' is readonly... can't figure our why.

Routine to update is similar to the following:

Error:
Message: Column 'ColumnUniqueName' is read only.

Source: System.Data

Trace:    at System.Data.DataRow.set_Item(DataColumn column, Object value)
   at System.Data.DataRowView.SetColumnValue(DataColumn column, Object value)
   at System.Data.DataRowView.set_Item(String property, Object value)

I want to be able to disable default commands on the RadRichTextBox (for example the SaveCommand command), and have their corresponding shortcut keys bubble up the visual tree (so the SaveCommand command's Ctrl+S shortcut can be captured at the Window level).  I've tried two methods of disabling a command:

#1 - Disabling the command

rtb.Commands.SaveCommand.Enabled = false;

#2 - Handling the CommandExecuting event and cancelling the command

void RadRichTextBoxEx_CommandExecuting(object sender, CommandExecutingEventArgs e)
{
    if (e.Command is SaveCommand)
        e.Cancel = true;
}

Unfortunately these methods seem to still mark the event as handled, and the KeyDown event never gets raised up the visual tree.  It seems this is a bug - is there a workaround or fix for it?

Thanks
