Programmatically Scrolling Grid Horizontally

Hello,

I want to be able to type in a header caption name into a text field, which would cause the grid to horizontally scroll to the column containing the typed in name. Is there a simple way to do this? I cannot figure out how to make the grid move left or right.

I thought scrollintoview might be the way to go but I cannot get it to work. I wish the documentation from Telerik was better.

Thanks

Missing Objects

The only Columns I have access to in the GridView namespace are the GridViewColumn and GridViewDataColumn. No GridViewComboBoxColumn, GridViewHyperLinkColumn, GridViewImageColumn, GridViewSelectColumn, etc...

Where do I find these?

Support for items other than MenuItems

Is it possible for the ContextMenu to support other controls such as ComboBoxes or TextBoxes? Every time I add and then try to click on them, the ContextMenu closes before you can make any changes.

Thanks,
Shawn

WPF datagrid selection problem

I have a datagrid which is styled for my requirement. Each datagrid row consists of 7 columns. The datatemplates of each column is as follows.

Column 1 - TextBox
Column 2 - ComboBox
Column 3 - TextBlock
Column 4 - TextBox
Column 5 - TextBox
Column 6 - TextBox
Column 7 - TextBlock

I have an event handler for the PreviewMouseLeftButtonDown of the datagrid, in which I select or deselect the clicked row using code (toggling selection). I have a button in my application.When this button is pressed, I set the selection mode of the datagrid to Microsoft.Windows.Controls.DataGridSelectionMode.Extended. Everything works fine until now.

But consider the following scenario.

The selection mode of the datagrid is DataGridSelectionMode.Extended. Now I click on the combobox, its dropdown menu opens, And when I press on the scrollbars of the dropdown of the combobox all the selected items of the datagrid gets deselected. In the callstack it is shown that it occurs due to an event raised from datagrids internal method HandleSelectionForCellInput(Microsoft.Windows.Controls.DataGridCell cell = {Microsoft.Windows.Controls.DataGridCell}, bool startDragging = true, bool allowsExtendSelect = true, bool allowsMinimalSelect = true). What is shown in the call stack is shown below.

Prevent focus when ScrollIntoView

Hello

I am building a windows application using the MVVM pattern.

My scenario is as following:
I have a window with several viewmodels in it.

(VM1) Viewmodel containing a list of items displayed through it's view with the help of RadGridView.

(VM2) Viewmodel with a search-like function, given a search criteria it sets the SelectedItem in VM1.

My first problem was that the selecteditem could be out of view. I made a mvvm-exception and added code behind and used ScrollIntoView to solve that problem (works like a charm).

    
            private void SelectionChangedHandler(object sender, Telerik.Windows.Controls.SelectionChangeEventArgs e)  
        
            {  
        
               if (this.radGridView.SelectedItem != null)  
        
               {  
        
                    this.radGridView.ScrollIntoView(radGridView.SelectedItem);  
        
               }  
        
            }

My problem now is that when scrolling occurs, the RadGridView gains focus. Is there any way to prevent this?

Best regards and thanks.
Thomas

Request: FilterMemberPath

Hi,

In my gridviewcolumns I can set a sortmemberpath and a groupmemberpath, what I'm missing is something like a FilterMemberPath.
Is it possible to implement this? This would be very helpful in a lookup value scenario.

Best regards,
Thomas.

Column Style?

Is there a way to either set the header to be vertical or to style a column in XAML. I have a old vb6 Flexgrid control that I need to replicate and I can do all of it in vb.net code -- but I wanted to style it to be grey(ghostwhite) and set the width and if possible define the static parts all in XAML and then just update the data parts in code

Using MDI RadWindows in xbap application

Hi,

I'd like to implement an MDI-like workspace in xbap application, is there any container for multiple RadWindows?

In my xbap application, I'd like the content-region would hold multiple RadWindows which can be dragged around, minimized, maximized, etc.

For dragging, I'd like it so that the windows themselves cannot be dragged outside of the mdi-window content region.

I'd appreciate any help/sample solution on how to implement this.

My xaml code is as follows:I have try to create MDI RadWindows in container1, but failed.

    
                    <telerik:RadDocking Name="radDocking1" Grid.Column="1" Grid.Row="1" AllowUnsafeMode="True">  
        
                        <telerik:RadDocking.DocumentHost> 
        
                            <telerik:RadSplitContainer InitialPosition="DockedLeft" Name="container1" HorizontalContentAlignment="Left">  
        
                                <telerik:RadPaneGroup Name="editGroup">  
        
                                </telerik:RadPaneGroup> 
        
                            </telerik:RadSplitContainer> 
        
                        </telerik:RadDocking.DocumentHost> 
        
                        <telerik:RadSplitContainer telerik:DockingPanel.InitialSize="150,150" InitialPosition="DockedBottom" Height="250">  
        
                            <telerik:RadPaneGroup Name="listGroup">  
        
                                <telerik:RadDocumentPane Title="Error Message" Name="errorMSGPane">  
        
                                    <telerik:RadDocumentPane.Content> 
        
                                        <TextBlock Name="tberrorMSG" Foreground="Red"> </TextBlock> 
        
                                    </telerik:RadDocumentPane.Content> 
        
                                </telerik:RadDocumentPane>                      
        
                            </telerik:RadPaneGroup>

get the selected RadDocumentPane in a RadPaneGroup

Hi, I need your help.
While in a RadPaneGroup, I can accomplish this by using " ((RadDocumentPane)radPaneGroup.SelectedItem).Name; " to get it.
but how to get the selected RadDocumentPane when I have dragged it out from a RadPaneGroup?

Thank you!

Docking
