Can't extend grid width

Hi,

User can't extend the grid width (No max width is set)

i do the following:
1) I open window
2) create a new UserControl with the radGrid
3) put the userControl in the window

It happens on every grid.
I tried to "play" with the width/max width of the grid and of the user control but with no success.

Thanks,
Ofer

User interaction with chart values

Hello everyone,

in my current project I need a chart that can be edited in real time by the user. Instead of using TextBoxes or Sliders to modify the data, the user wants to drag and drop values (points, bars, you name it) in the chart in real time.

Any idea if this is currently supported, or how could I get it done?

Thanks in advance

Checkbox Column

I'm trying to add a column with checkboxes that represent a boolean value to my gridview.

The examples I've seen so far follow the pattern:

<telerik:GridViewDataColumn IsReadOnly="True" DataMemberBinding="{Binding ID}">

<telerik:GridViewDataColumn.CellTemplate>

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

But, The CellTemplate, for some reason, is not available to me, what am I missing?

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.

PresentationFramework.dll!System.Windows.Controls.SelectionChangedEventArgs.InvokeEventHandler(System.Delegate genericHandler, object genericTarget) + 0x31 bytes

Now I would like to avoid this internal call for selection from datagrid. Is there any way to do that? Please advise.

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
