Set property isSelected for cell

I am using Telerik version 2014.1.331.45

I have a RadGridView like:

<telerik:RadGridView Name="RadGridView" ItemsSource="{Binding DynamicValues, Mode=TwoWay}"

<br>                             SelectedItem="{Binding SelectedItem, Mode=OneWayToSource}" CanUserDeleteRows="True" <

br

>                             CanUserInsertRows="True" CanUserReorderColumns="False" CanUserSortColumns="False" <

br> ShowGroupPanel="False" IsFilteringAllowed="False" SelectionMode="Extended" SelectionUnit="Mixed" IsSynchronizedWithCurrentItem="True" <br

>                             behavoirs:ValidationBehavior.IsValidationEnabled="True" ClipboardPasteMode="SkipHiddenColumns">

I need to select all cells of column on clicked column header

i wrote next code for make header clickable:

foreach (var column in RadGridView.Columns) { var temp = column.Header; column.Header = new MyButton { Content = temp.ToString(), ViewModel = this }; }

and custom button class:

private class MyButton :RadButton { public override string ToString() { return Content.ToString(); } protected override void OnMouseDown(MouseButtonEventArgs e) { if (ViewModel.columnHeaders.ContainsKey(e.Source.ToString())) { foreach (var value in ViewModel.RadGridView.Items) {<br

>                        var row = ViewModel.RadGridView.ItemContainerGenerator.ContainerFromItem(value) as GridViewRow;<

br> if (row != null) row.Cells[index].IsSelected ??? } } base.OnMouseDown(e); } public EditViewModelBase ViewModel { get; set; } }

but row.Cells[index] does not have property IsSelected, how I can set cell property selected?

ActiveTool=MouseTool.ConnectorTool Does not work for MVVM

Hi,

I apply mvvm pattern for RadDiagram. Both shapes and connections are bound to classes that derive from the Diagram.Extension classes. Everything works quite fine except, I cannot add new connection using the ActiveTool=MouseTool.ConnectorTool. When I set the ActiveTool to Connector tool, the mouse cursor changes to connector mode but it does not draw any arrow when clicked and moved on the Diagram. How can I provide the functionality to add connections between the shapes and keep the MVVM pattern?

Thanks in advance,
Semih

Can't Paste more than once into RadTextInputBox

Hi,
We've just upgraded to Q2 2014 and replaced retired RadMaskedTextBox with RadMaskedTextInput with these properties set
<Setter Property="Mask" Value="###-###-####" />
<Setter Property="EmptyContent" Value="___-___-____" />
<Setter Property="IsClearButtonVisible" Value="False" />
<Setter Property="AllowInvalidValues" Value="False"></Setter>

Two issues:
1. Mask is set to ###-###-####. However, it allows for spaces.
2. I can't paste more than once into it. First Paste works fine, but then if I delete the contents and paste again with Context Menu Paste, nothing happens. If I use Ctrl+V, it does paste but only after second try.

Is there a way to fix both?

RadToolBar not working after upgrade

I just upgraded to the latest WPF controls. Now the tool bar is acting funky. I have a grid within the toolbar that has various labels and text boxes. It displayed fine before the upgrade. Now the tool bar displays a black tool bar but by clicking on the arrow on the far right side of the control the correct tool bar pops up above the tool bar.

I've played around with the band and band index settings but nothing works.

Any help would be greatly appreciated.

RadDataPager refresh

Hello,

I have a view with RadGridView and RadDataPager. Grid´s source is PagedSource of data pager. Data pager is bound to IQueryable of items so Data pager manages data reading itself. Paging is working well but I don´t know how to refresh grid if user pressed a button for manual refresh. I have tried to use Grid.Rebind() but it didn' t work. Is there any method I could call to explicitly cause Data pager to reads data from database? And is there any event triggered during it? Because I would like to use busy indicator during the refresh.

Thanks,
Karel Bem

Adding an AggregateFunction to a column at runtime does not show its result before resorting or grouping

Hi support,

I am adding a AggregateFunction to a gridcolumn with the following code:

bool showFooter = false;
foreach (var col in radGridView.Columns)
{
    if (col.UniqueName == "dauer") // Column with double-values
    {
        col.AggregateFunctions.Add(new SumFunction() { ResultFormatString = strFormat, SourceField = col.UniqueName });
        showFooter = true;
    }
}
radGridView.ShowColumnFooters = showFooter;

Adding a footer should only happens if my table has a column of data-type double named "dauer" otherwise columnfooters should not been shown. After doing this the footer has correctly been show but the first time the sum of the column is displayed when I sort a column of the grid via clicking on a column header.

You can reproduce this behavior in your sample-program "persistence framework / gridview serialization" when you put these lines of code in function "OnLoad" of Example.xaml.cs after calling this.EnsureLoadState() (of course you have to add a new column "dauer" to your dataset)

What do I have to do to show the results of the aggregate-function directly.

Thanks in advance
