Hello,

I believe I've run into another breaking change with the Q1 2009 version of the grid.  In my app I have some functionality where the user can define some of the properties of a grid, one of them being the column widths.  When the user is looking at some data in the grid and they resize a column I need to update by business object so that I can display the grid with the same widths the next time.

In the previous version I accomplished this by having a two way binding between the Width property of a grid column and a width property on my business object (using a converter to translate back and forth between a numeric value and a GridLength).  This worked perfectly as every time the user changed a column width my object was updated. 

In the Q109 version, resizing a column doesn't seem to update the column width anymore so my object never gets updated.  The only time the width gets updated is when you double click in the header to make the column fit the contents.  This also has the unfortunate side effect of setting the column with to Auto and the value to 1, which is not desired.  I would expect that the column would be resized, but the mode stay in Pixel mode like it used to.

Is there any way to get the grid to behave like it used to?  If not, can someone please suggest a way for me to know when a column gets resized and then get the actual width of the column?  I had a similar post a while back but that method doesn't seem to work anymore either.

Thanks,

Joel

As we know, The treeview control enables check boxes for all nodes. Is it possible to show the check boxes for sepecific nodes? For example, I want to use a treeview control to list all files in Drive C with forders, only the file node has a check box, but the root and folder nodes do not have checkboxes shown.

Thank you very much.

Is it possible to have my groups which I have defined with a Group Descriptor in the grid view mark-up automatically expanded when the grid view is loaded?

How can I change the mouseover of the contextmenu when I add a checkbox? I can easily change radmenuitems but haven't found a way yet to change the checkbox' team. I did check in the contextmenu itself for teams but nothing exists there whatsoever about mouseover themes.

By Default we need to hit Insert Key to add a new record to RadGridView. how can i change this behavior to Default WPF Grid i.e. just upon hitting tab on last record a new record will be inserted.

Is it possible to draw in the charting area? For example, I would like to draw a red line, perhaps, through the chart at the Y-Value of 60 (assuming this chart has one Y-Axis). Or perhaps I would like to shade the area above the Y-Value of 100 red. I know I can do the shading by setting the background brush, but its critical to know where the Y-Value of 60 or 100 is in these examples. Is this possible with RadChart?

Hi,

Hi All

I have tried all manor of solutions to this problem.

Basically I have an attributes table which contains a type. this type is bound to a GridViewComboBoxColumn. when the selection in this column is changed, it needs to set the isvisible value of other columns in the same grid row.

So, in the usual way, I have created a converter such as this:

in the xaml, the converter is called like this:

The value for the cell is updated when the attribute_id is changed, but the visibility converter is never called.


the second option that I have tried is to use the GridViewdataColumn element, such as this:

gridAttributes_attributeType1 is the name of the GridViewComboBoxColumn.

This also does not call the converter as I suspect that the path SelectedValue does not exist in a GridViewComboBoxColumn.

The solution does call the converter however, if I bind it to a combo outside of the gridview..

Is there any solution to this problem.

Regards

Nick

Hi,
i want to use checkboxes in several columns and therefore my code - for 1 gridview column - looks like this:
____________________________________________________________________

<telerik:GridViewDataColumn x:Name="colResultNT" Header="Result NT" IsReadOnly="True" IsEnabled="False" DataMemberBinding="{Binding ResultNt}">
                                </telerik:GridViewDataColumn>
                                <telerik:GridViewDataColumn x:Name="colReview" Header="Review Needed?" DataMemberBinding="{Binding IsReviewNeeded}">
                                    <telerik:GridViewDataColumn.CellStyle>
                                        <Style TargetType="GridView:GridViewCell">
                                            <Setter Property="Template">
                                                <Setter.Value>
                                                    <ControlTemplate TargetType="GridView:GridViewCell">
                                                        <CheckBox Margin="5,0,0,0"
                                                                HorizontalAlignment="Left"
                                                                VerticalAlignment="Center"
                                                                IsChecked="{Binding IsReviewNeeded, Mode=TwoWay}" />
                                                    </ControlTemplate>
                                                </Setter.Value>
                                            </Setter>
                                        </Style>
                                    </telerik:GridViewDataColumn.CellStyle>                                    
                                </telerik:GridViewDataColumn>  
____________________________________________________________________
This code works fine, but actually the vertical grid line on the right sight disappered (see attached screenshot). Any ideas why? How can i get it back?
Thx in advance
                            
                              

Hello,

I have a difficulty about binding a list of type Binding<T> list to Grid. The binding is working fine, but grouping is not working on the side of XAML.

Am I doing something wrong ?
