Created Issue: WPF DataGrid: Problem resizing the rows from code behind. [10978]

cristianmad — Fri, 20 Nov 2009 16:38:28 GMT

Hi,
I have tried to set different row heights from code behind when I noticed a very strange behavior.
Here is my code:
<Window x:Class="WpfApplication24.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="254*" />
<RowDefinition Height="33*" />
<RowDefinition Height="24*" />
</Grid.RowDefinitions>
<DataGrid x:Name="dataGrid1" AutoGenerateColumns="True" Margin="0,1,0,0" CanUserSortColumns="False" EnableRowVirtualization="False" CanUserResizeRows="True" CanUserDeleteRows="False" />
<Button Content="Button1" Grid.Row="1" Name="button1" Click="button1_Click" />
<Button Content="Button1" Grid.Row="2" Height="23" HorizontalAlignment="Left" Name="button2" VerticalAlignment="Top" Width="503" Click="button2_Click" />
</Grid>
</Window>

using System.Collections.Generic;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;

namespace WpfApplication24
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}

private void button1_Click(object sender, RoutedEventArgs e)
{
List<Person> someItems = new List<Person>();
someItems.Add(new Person("name 1", "address 1"));
someItems.Add(new Person("name 2", "address 2"));
someItems.Add(new Person("name 3", "address 3"));
someItems.Add(new Person("name 4", "address 4"));
someItems.Add(new Person("name 5", "address 5"));
someItems.Add(new Person("name 6", "address 6"));
dataGrid1.ItemsSource = someItems;
}

public class Person
{
public Person(string name, string address)
{
this.Name = name;
this.Address = address;
}

public string Name { get; set; }

public string Address { get; private set; }
}

private void button2_Click(object sender, RoutedEventArgs e)
{
DataGridRow someRow = dataGrid1.ItemContainerGenerator.ContainerFromIndex(1) as DataGridRow;
someRow.Height = 100;
}
}
}

Steps to reproduce:
1. Press Button1 to load some data into the datagrid.
2. Press Button2 to set the height of the 2nd row to 100.
3. Try to resize the 2nd row using the mouse.

I am attaching the project and a snapshot also.

I have tried (and reproduced) this with both the DataGrid from the WPFToolkit and the DataGrid which comes with VisualStudio2010 Beta2.

Is there another way that I could set the height of a certain row from code behind?

Thanks,
Cristian

Commented Issue: DataGrid RowDetailTemplate will only adjust to width increase, not decrease [10196]

JustinBelcher — Thu, 19 Nov 2009 21:57:21 GMT

I believe I have found a bug in the way the DataGrid from the WPF Toolkit handles resizing when using RowDetailTemplates.

More specifically, I use a RowDetailTemplate that contains content aligned to the right (originally, it was a textbox that was supposed to fill all the space, but for the purpose of reporting this issue, it is simpler to demonstrate with a right-aligned text block).
When the width of the datagrid is increased (window is made wider), the width of the RowDetail-area is also increased, which is fine.
If, then, the width is decreased again, the RowDetail area stays wide, which means right-aligned contents disappears.

Here is a minimal demonstrator:

<Window x:Class="QuickTest.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:toolkit="http://schemas.microsoft.com/wpf/2008/toolkit"
Title="Window1" Height="300" Width="300">
<toolkit:DataGrid AutoGenerateColumns="False" SelectionUnit="FullRow"
RowDetailsVisibilityMode="VisibleWhenSelected">
<toolkit:DataGrid.Columns>
<toolkit:DataGridTextColumn Header="Sample column - click empty row" Width="*"></toolkit:DataGridTextColumn>
</toolkit:DataGrid.Columns>
<toolkit:DataGrid.RowDetailsTemplate>
<DataTemplate>
<Grid Margin="5">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"></RowDefinition>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"></ColumnDefinition>
<ColumnDefinition Width="Auto"></ColumnDefinition>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="1">move right window border further right and then left again - behold, this text disappears!</TextBlock>
</Grid>
</DataTemplate>
</toolkit:DataGrid.RowDetailsTemplate> >
</toolkit:DataGrid>
</Window>

Code-behind is not necessary for this example. To make the problem appear, make the window first wider and then narrow again.

Created Issue: AttributeTableBuilder exists in two referenced assemblies [10956]

thoemmi — Wed, 18 Nov 2009 08:01:54 GMT

When I compile WPFToolkit, I get following error message for Controls.DataVisualization.Toolkit.Design:
The type 'Microsoft.Windows.Design.Metadata.AttributeTableBuilder' exists in both 'c:\Program Files (x86)\Microsoft Expression\Blend 3\Microsoft.Windows.Design.Extensibility\Microsoft.Windows.Design.Extensibility.dll' and 'c:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\PublicAssemblies\Microsoft.Windows.Design.dll'

Created Issue: DataGrid: binding - clear - binding not grouping [10954]

midspace — Wed, 18 Nov 2009 01:07:56 GMT

Steps...
1. Binding a DataGrid to a CollectionViewSource with GroupDescriptions specified, works the first time around.
2. Clearing the binding on the DataGrid.ItemsSourceProperty (or setting it to null)
3. and then binding it a second time to a new CollectionViewSource with GroupDescriptions, finds that the Grouping no long appears on the DataGrid.

Created Issue: DataGrid : grouped items, editing cell TAB out of shifts rows vertically [10953]

midspace — Tue, 17 Nov 2009 22:40:11 GMT

Issue where user may click on a cell to edit an item in a set of grouped data. Tabbing to the next cell, causes the row to move to the bottom of the group's collection of items.
The item in the cell doesn't even have to be edited. Simply activate the editing, and tab (or shift-tab) to an adjacent cell.

This is disconcerting, and our users have complained to us.

The only workaround I have at the moment is to enforce sorting on a secondary column which has unique data, which fixes all the rows in place. This however requires some juggling around whenever the user wants to sort the datagrid.

Note, this may be similar to Item 10065

Commented Issue: WPFDataGrid: Some records are shifted (panned horizontally) [10311]

avoloschuk — Fri, 13 Nov 2009 21:32:42 GMT

When datagrid contains a lot of records (more than 100) I have experienced with problem that some record are panned horizontally.

Sometimes panned records repeated after some period (for exaple each 30-th record), but sometimes without any regularity (like in screenshot in attachment)

This issue has been reproduced since January version.

Commented Issue: Chart DateTimeAxis: binding IntervalType freeze .Net and appli on Window.Show [10935]

RenaudLZ — Fri, 13 Nov 2009 14:47:37 GMT

Hi,

When binding the IntervalType property of the DateTimesAxis to a ViewModel class, it crashed .Net when trying o refresh the preview area.

If I escape the refresh of the preview and launch the debugger, the Window never opens.

Here a code sample of the xaml (DataContext is set to the ViewModel class before the window.show in the app startup :

<WPFToolkitCharting:Chart Grid.Row="1">
<WPFToolkitCharting:Chart.Axes>
<WPFToolkitCharting:LinearAxis Orientation="Y"/>
<WPFToolkitCharting:DateTimeAxis Orientation="X"
ShowGridLines="True"
IntervalType="{Binding DataSetChartVM.IntervalType}" Interval="1" />
</WPFToolkitCharting:Chart.Axes>
<WPFToolkitCharting:Chart.Series>
<WPFToolkitCharting:LineSeries Title="{Binding Name}" IndependentValueBinding="{Binding Date}"
DependentValueBinding="{Binding Value}" ItemsSource="{Binding Items}"/>
</WPFToolkitCharting:Chart.Series>
</WPFToolkitCharting:Chart>

I did not get the chance yet to run this with the Tollkit source to this what happens.

Any thought ?

Cheers

Created Issue: SharedSizeGroup GridSplitter Issue [10934]

fallenidol — Fri, 13 Nov 2009 12:04:23 GMT

I wish to use a Grid for my top level layout. The Grid will have 1 column and n rows. Each row in the Grid should also contain a Grid which shall have 3 columns and 1 row. In the second column is a GridSplitter and I am trying to use a SharedSizeGroup so that this changes the size of the first column across all of the nested Grids.

Here is what i have...and it works!!...well kind of...if you click the splitter and resize without letting go it works...but for some reason if you resize something and let go of the mouse and then attempt to resize using a different row it seems to "stick".

<pre>
<Grid Grid.IsSharedSizeScope="True">
<Grid.RowDefinitions>
<RowDefinition></RowDefinition>
<RowDefinition></RowDefinition>
</Grid.RowDefinitions>


<Grid Grid.Row="0">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="A" Width="Auto"></ColumnDefinition>
<ColumnDefinition SharedSizeGroup="B" Width="Auto"></ColumnDefinition>
<ColumnDefinition SharedSizeGroup="C" Width="Auto"></ColumnDefinition>
</Grid.ColumnDefinitions>

<Label Grid.Column="0">One-Left</Label>
<GridSplitter Grid.Column="1" Width="5" Background="DarkGray"></GridSplitter>
<Label Grid.Column="2">One-Right</Label>
</Grid>


<Grid Grid.Row="1">
<Grid.ColumnDefinitions>
<ColumnDefinition SharedSizeGroup="A" Width="Auto"></ColumnDefinition>
<ColumnDefinition SharedSizeGroup="B" Width="Auto"></ColumnDefinition>
<ColumnDefinition SharedSizeGroup="C" Width="Auto"></ColumnDefinition>
</Grid.ColumnDefinitions>

<Label Grid.Column="0">Two-Left</Label>
<GridSplitter Grid.Column="1" Width="5" Background="DarkGray"></GridSplitter>
<Label Grid.Column="2">Two-Right</Label>
</Grid>

</Grid></pre>

Created Issue: There is a bug when scrolling data on a DataGrid [10911]

gabriel_ir — Mon, 09 Nov 2009 18:33:36 GMT

When I use one Datagrid on a WPF Window without template columns there is no problem, but if I add another Datagrid or add a template column with a TextBox inside, and I scroll the DataGrid, I can watch values inside the DataGrid changing alleatory.

I am using dinamic databinding from a database this way:

MyDataGrid.DataContext = MyDataTable

So, I first get data from the database into an ADO.NET DataTable object, then I bind the DataGrid control.

Then I format data inside the DataGrid control this way:

MyDataGrid.Columns(2).GetCellContent(MyDataGrid.Items(3)).SetValue(TextBlock.TextProperty, FormatCurrency(MyDataTable.Rows(3)("Total"), 2))

In this case, I set the value of third column, fourth row to the value of "Total" column with currency format.

Then, when I scroll either of the DataGrid controls, I can watch the values changing alleatory.

Commented Issue: AutoGenerateColumns fails when column name contains a period [9852]

hrkyemba — Thu, 05 Nov 2009 18:14:57 GMT

When using AutoGenerateColumns="true" to bind to a DataTable that has a column with a period (.) in its name (for example, "my.columnName"), then the column will render in the DataGrid, but the cells will not display any data.
Comments: ** Comment from web user: hrkyemba **

Why is the status of this item fixed? It is common to have a period in a column name when you are joining multiple tables and need to disambiguate the column name.

Commented Issue: DataGrid: The ESC and Backspace key produces an unrecognized character [10246]

tommywtf — Wed, 04 Nov 2009 02:58:59 GMT

Select a DataGridTextColumn cell and press the ESC or Backspace key. Then the cell enters the edit mode and shows an unrecognized character ('[]') in the TextBox.

However, the behavior should be similar to Microsoft Excel.
1) ESC doesn't do anything when the cell is not in edit mode.
2) The Backspace key should delete the content of the cell and it should enter the edit mode.

I have the same problem.~~
Please fix it.
Thanks!

Commented Issue: Datagrid frozen columns and group header [10741]

cuongnv3 — Fri, 30 Oct 2009 04:55:49 GMT

Dear all

I am using the datagrid from the toolkit. I am freezing the first three columns of the datagrid by setting the following: FrozenColumnCount="3". It's working fine, but I have three group headers, which do not get frozen while scrolling. Is there any way to freeze them too?

Thank you

Angelo

It's a very serious problem with my project. Seem that no one has ever had the same problem before. Please inform me if you have any solution.

Created Issue: DataGrid handles CTRL+TAB key and thus TabControl cannot see it [10835]

kojiishi — Tue, 27 Oct 2009 05:26:38 GMT

When DataGrid is within TabControl, and when the keyboard focus is on the DataGrid, CTRL + TAB does not switch between tabs.

It works as expected when the focus is not on the DataGrid.
