Hello, please i need your help,

 

I have a RadGridView and the rows have different types, for example: Type A, Type B, .... and sometimes there is a relation between rows, and if a user try to delete a row (for example row A) I check if there is a relation between the row that the user want to delete (row A) and all the rows of the RadGridView, and if there is a relation I propose to the user if he want to delete the row (Row B for example) (or rows) who the row A have a relation.

I used the event RowsChanging to get the index of the rows that the user wants to delete, like this, and then I can delete the rows who have a relation with the row A.

 

private void radGridView_RowsChanging(object sender, GridViewCollectionChangingEventArgs e)
        {
            if (e.Action == NotifyCollectionChangedAction.Remove)  // The Action is to delet the row A
            {

              //  if(I check if row A have a relation with another row)

             {

             //i delet this rows

        radGridView .Rows.RemoveAt(indexoftherowiwanttodelet);

             }         

      }

}

 

My problem is:

If the index of the row A is smaller than the index of the row B, the code works very well.
But if the index of the row A is bigger than the row B, I have an exception: 

'System. ArgumentOutOfRangeException' occurred in mscorlib.dll

 

I need your help and thank you.

Hi,

I want to save selections like shape border thickness as settings so when the user work with the tool again the last selected thickness should be selected instead of the default value.

How do I approach and solve this?

 

Best regards

Hi,

is it possible to save the image editor settings I used last? I would like to have the same StrokeColor, Shape and StrokeThickness again if I open another picture with the imageeditor.

Best regards.

Is there any way to change the circle size of the expander control? Or could you provide an example for replacing the template of the expander control? I would like to increase the size of the circle to make it more touch friendly.

Regards,
Peter

When I programatically add a radpane to docking. It is coming out only as tall as the header of a pane. (Picture attached of result.)

I have tried a few methods.

Here is what I am trying:

The InlineUiContainer is allowed to be inserted into RadRichTextBox officially by Telerik.

But there're some problems:

When I insert  a <Textbox> in to  RadRichTextBox 

                        <telerik:InlineUIContainer>
                            <TextBox Width="100" Height="50"/>
                        </telerik:InlineUIContainer>

       The TextBox can be shown in the RadRichTextBox correctly, and input charactors in inner TextBox correctly. But when I press "Backspace", the cursor will jump to to outer RadRichTextBox instead of delete the last character in inner TextBox !

       I used to think it's caused by the Microsoft WPF and Telerik WPF these 2 mechanisms (incompatible).Then I tried to use a RadTextBox, but no this control (with the acceptable reason: no color can be set on this control, so theme is unnecessary). 

       Fortunately, I found a Telerik control called telerik:RadMaskedTextInput, then I tried it as 

                        <telerik:InlineUIContainer>
                            <telerik:RadMaskedTextInput Width="100" Height="50" TextMode="PlainText"/>
                        </telerik:InlineUIContainer>

       But the problem is still !!!!  Press "backspace" in the inner RadMaskedTextInput will make the cursor jump into the outer RadRichTextBox .............

       On the other hand, if you insert a RadRichTextB​ox into a RadRichTextBox ,  the cursor is Okay both in inner and outer RadRichTextBox .

       I'm using ver 2014Q3.

       Then Whether this problem has been fixed now ? If yes , could you please tell me the ver?

       

Hello everyone,

We are having issues with vertical scroll when collapse/expand items in the TreeListView. Scroll starts to jump if we change style for GridViewCell:


XAML for TreeListView:


Please advice.

I need to create a graph that has multiple line series defined by pairs of x-y coordinates ( one start point and one end point). On the same graph I need to have several scatter points with no connecting lines. Also if there's a way to specify a straight line between some of the points and a curved line between others that'd be great. I'm currently researching WPF graphs so I don't have any code to show yet.

Hi,

I can successfully provide an initial sort order for my VirtualGrid using this code in the code behind file, as prescribed by your documentation:

var sortDescriptor = this.VirtualGrid.GetSortDescriptorForColumn(0);
sortDescriptor.SortDirection = System.ComponentModel.ListSortDirection.Ascending;

sortDescriptor.IsActive = true;

However, for reasons beyond the scope of this issue, my source data (an observable collection) and my custom data provider are created in my view model. My custom data provider is bound to the VirtualGrid via XAML.

Therefore, any attempt to apply your sorting code in the constructor of the code behind file fails because both the DataContext and DataProvider properties are not yet assigned in that instant (they are null), i.e. they are not populated until the View Model constructor files.

I can achieve what I want by placing the aforementioned code in the VirtualGrid's Loaded event in the code-behind file, but as a Newbie, I am concerned whether this is the correct solution.
