[Solved] Exception when changing ItemsSource

Not sure where to file this bug report, but when changing the ItemsSource property of the grid we sometimes get

    
            {System.NullReferenceException: Object reference not set to an instance of an object. 
        
               at Telerik.Windows.Controls.UI.DistinctFilterControl.PopulateDistinctValues() 
        
               at Telerik.Windows.Controls.UI.DistinctFilterControl.<DistinctFilterControl_Loaded>b__0()}

we have IsFilteringAllowed set to False if that helps.

Many thanks,

Will Holley

[Solved] Custom sort behaviour

The current SortingRequested event only fires when the field being sorted implenents IComparable (seemly making the custom sort behaviour irrelevant?). In order to work around this (we want to sort at the database) I tried subclassing GridViewDataColumn so I could override CanSort() to remove this constraint. However, CanSort is not a virtual method so this doesn't work.

Do you have any suggestions to work around this behaviour? Adding a dummy IComparable implmentation to all of our entities is not really a good solution for us.

Many thanks,

Will Holley

[Solved] RadGridView Beta 2

Hi Guys - congratulations on Beta 2 - it's a big step forward and seems to fix most of the issues we encountered in the first release!

Just a couple of issues that have come up for us with the new release:

1. Is it possible to turn off the filtering feature?
2. The autofit column algorithm does not include the header text (we would expect it to)
3. When adding field descriptions dynamically and refreshing the data, we get:

{System.NullReferenceException: Object reference not set to an instance of an object.

   at Telerik.Windows.Controls.UI.DistinctFilterControl.PopulateDistinctValues()

   at Telerik.Windows.Controls.UI.DistinctFilterControl.<DistinctFilterControl_Loaded>b__0()}

Any help with these would be much appreciated,

Will Holley

[Solved] Binding to LeftDoubleClick

It would be useful to be able to bind commands to LeftMouseClick (using RadGridView.InputBindings). For example,

    
            <UI:RadGridView.InputBindings> 
        
                 <MouseBinding Command="{x:Static Entity:EntityCommands.EditCommand}" MouseAction="LeftDoubleClick"/> 
        
            </UI:RadGridView.InputBindings>

However, it appears that this is not supported, even when the fields are set to readonly.

If I change the above snippet to use MiddleClick, the command is fired.

Is this a bug or intended behaviour?

Many thanks,

Will Holley

Filtering on specific columns / use of Simple Theme

Hi Telerik Team.

Thanks for the filtering functionality in Beta 2

2 questions

1: is it possible to switch off filtering on a specific column. i haven't been able to find a property to set on the column only on the entire grid.?

2: use of the Simple theme which is provided in your examples. I believe the easiest way to set the Theme property on the grid must be Telerik:Theming.Theme="Simple"
but "Simple" is not part of the values to choose. I have added the Reference "Telerik.Windows.Controls.UI.Simple" to the project. but still its not able to set. what am i doing wrong.

Hi,

I have a problem with getting the child row that is selected.

I have a grid with in the first column of the child grid a checkbox to select/deselect. When the check changed i handle the event. But i get the parentrow in the selected row and not the child row

How can i get the selected child row?

Little info on how i fill the childcolumn

    
              radGridResubmit.TableDefinition.ChildTableDefinitions[0].AutoGenerateFieldDescriptors = false;  
        
                                Telerik.Windows.Controls.UI.GridViewDataColumn desc = new Telerik.Windows.Controls.UI.GridViewDataColumn();  
        
                                desc.HeaderText = "";  
        
                                desc.UniqueName = "IsSelectedForResubmit";  
        
                                desc.IsAutoGenerated = true;  
        
                                desc.CellStyle = new Style();  
        
                                desc.CellStyle.Setters.Add(new Setter(TemplateProperty, FindResource("CheckBoxColumnTemplateAction")));  
        
                                radGridResubmit.TableDefinition.ChildTableDefinitions[0].FieldDescriptors.Add(desc);  
        
                                desc = new GridViewDataColumn();  
        
                                desc.IsReadOnly = true;  
        
                                desc.HeaderText = "ActionName";  
        
                                desc.UniqueName = "ActionName";  
        
                                desc.IsAutoGenerated = true;  
        
                                radGridResubmit.TableDefinition.ChildTableDefinitions[0].FieldDescriptors.Add(desc);

[Solved] Comments on the beta process

It worries me that there is not going to be a feature complete beta of these controls - beta 1 and 2 are quite buggy for us and seem to be in some state of flux - . If features are still being added, can we expect the quality to improve?

For future releases, would you consider producing public nightly builds (similar to the way JetBrains do with Resharper) and also making debug symbols available to help with diagnosis of problems?

Kind regards,

Will Holley

[Solved] set color of entire row with column value as parameter

Hi,

How can i set the background of a row to a color based on the value of one of its columns?

I have written a convert that changes the statusid to a brush but i don't know how to apply it to the row

I tried this but that didn't work

    
            <Grid.Resources> 
        
                        <Style TargetType="{x:Type Telerik:GridViewRow}">  
        
                            <Setter Property="Background">  
        
                                <Setter.Value> 
        
                                    <SolidColorBrush Color="{Binding Path=StatusId, Converter={StaticResource ConvertDocumentColor}}"></SolidColorBrush> 
        
                                </Setter.Value> 
        
                            </Setter> 
        
                        </Style> 
        
                    </Grid.Resources>

Regards,

Bram
