Only the first item in Combobox (selectedIndex = 0) should be editable. I have got it already. But the problem is that the selected text didn't get highlighted.
Any help would be appreciated!

I have an an DataGrid in which I load Data from an ObservableCollection and each row has an CheckBox so that I can have a list of checked Rows. Now I wanted to add an new Column to the DataGrid which is an ComboBox and in the ComboBox is a list with Checkboxen. I want for each row that when I check one Row and then when I check other Items from the ComboBox that I can combine the selected row and the selected values from my ComboBox.
The problem is that if I check one Row of the Combobox item it will check for every other ComboBox that appears in the DataGrid.
I want only to check the value of the combobox for one row and combine it with the Value of the checked row of the datagrid.
Here is my Code of my DataGrid:
<DataGrid Style="{DynamicResource DataGridStyle}"

my itemtemplate of my ComboBox:
<Setter Property="ItemTemplate">
<Setter.Value>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<CheckBox IsChecked="{Binding Path=cmbIsChecked, Mode=TwoWay}" Width="20"/>
<TextBlock Text="{Binding Path=Spaltenname}" VerticalAlignment="Center" />
</StackPanel>
</DataTemplate>
</Setter.Value>
</Setter>
my "bischenanders" collection (sry for that bad name I will fix that in the future)
my outputColumns class:
public class OutputColumns
{
public string Spaltenname{ get; set; }
public bool IsChecked { get; set; }
public bool cmbIsChecked { get; set; }
}
}
thats the way I read the selected Items for the rows and for the Combobox rows
public List<OutputColumns> GetSelectedItems()
{
var selectedItems = new List<OutputColumns>();
foreach (OutputColumns item in View.bischenanders)
{
try
{
if (item.IsChecked)
{
selectedItems.Add(item);
}
}
catch
{
}
}
return selectedItems;
}
public List<OutputColumns> cmbGetSelectedItems()
{
var selectedItems = new List<OutputColumns>();
foreach (OutputColumns item in View.bischenanders)
{
try
{
if (item.cmbIsChecked)
{
selectedItems.Add(item);
}
}
catch
{
}
}
return selectedItems;
}
So that If this row is checked:
Picture
and in the combobox that 2 rows are checked:
Picture2
then I want that these 3 values are getting Combined
but when I check in one CombobBox every combobox in the DataGrid has the same checked Values
It looks like that every time I open a new ComboBox he getting the data from the class and then there will the programm find a version where it is checked, because ComboBoxs I already have open get there own checked values, only the new ones getting the checked one that are checked in the previous checkbox.
Thanks for help!
I am trying to change the foreground color of ComboBoxItem, however it does not apply, what am I doing wrong? Also I'm trying to change the foreground color of hovers on ComboBoxItem which does not work as well.
Here is my xaml:
<ComboBox Foreground="Yellow" Name="txtDispatch" HorizontalAlignment="Stretch" VerticalAlignment="Bottom" Margin="0,0,15,0" Grid.Column="2" Grid.Row="0" materialDesign:HintAssist.Hint="Select Dispatch" SelectionChanged="txtDispatch_SelectionChanged">
<ComboBox.ItemTemplate >
<DataTemplate >
<CheckBox Foreground="Yellow" Name="chkDispatch" Width="220" Checked="txtDispatch_Checked" Unchecked="txtDispatch_Checked" Content="{Binding Dispatch.id}" IsChecked="{Binding Check_Status}" CommandParameter="{Binding Dispatch.id}" />
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
<ComboBox Foreground="Black">

Very Simple. Use the style.
I am trying to have p:MarqueeTextBlock to only scroll on ListBox IsSelected under TargetType="{x:Type ListBoxItem}".
Having trouble to work out adding a MultiTrigger conditions (fired when IsSelected becomes True or False) to change the Property="Scroll" of the p:MarqueeTextBlock to Off or LeftTypewriter. In addition not sure how to reference the p:MarqueeTextBlock in the DataTemplate; perhaps if I provide it an x:Name? However I get Template property has already been set on DataTemplate.
I need to add AOTbMain_MARQUEE somehow in x:Key="ListBoxStyle_GAME" like:
<p:MarqueeTextBlock Text="{Binding Path=Title}" Style="{StaticResource AOTbMain_MARQUEE}"/>

The following Style will show the AutoscrollListBox as content of the DataTemplate. Once the ListBoxItem is selected it will display the MarqueeTextBlock instead. If unselected it will switch back to the AutoscrollListBox.
Solution 1
<Grid>
<AutoscrollListBox Name="Items" >
<AutoscrollListBox.ItemTemplate>
<DataTemplate>
<DataTemplate.Resources>
<AutoscaleTextBlock x:Key="AutoscaleTextBlock"
Text="{Binding Title}"
Style="{StaticResource ListBoxStyle_BASETB}"
x:Shared="False" />
<MarqueeTextBlock x:Key="MarqueeTextBlock"
Text="{Binding Title}"
Style="{StaticResource AOTbMain_MARQUEE}"
x:Shared="False" />
</DataTemplate.Resources>
<ContentControl x:Name="ContentPresenter" />
<DataTemplate.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=ListBoxItem}, Path=IsSelected}"
Value="False">
<Setter TargetName="ContentPresenter"
Property="Content"
Value="{StaticResource AutoscaleTextBlock}"/>
</DataTrigger>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=ListBoxItem}, Path=IsSelected}"
Value="True">
<Setter TargetName="ContentPresenter"
Property="Content"
Value="{StaticResource MarqueeTextBlock}"/>
</DataTrigger>
</DataTemplate.Triggers>
</DataTemplate>
</AutoscrollListBox.ItemTemplate>
</AutoscrollListBox>
</Grid>
Solution 2
In case you are working with nested resource dictionaries and can't apply the x:Shared attribute you can swap the controls directly from the Trigger:
<Grid>
<AutoscrollListBox Name="Items" >
<AutoscrollListBox.ItemTemplate>
<DataTemplate>
<ContentControl x:Name="ContentPresenter" />
<DataTemplate.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=ListBoxItem}, Path=IsSelected}"
Value="False">
<Setter TargetName="ContentPresenter"
Property="Content">
<Setter.Value>
<AutoscaleTextBlock Text="{Binding Title}"
Style="{StaticResource AOTbMain_MARQUEE}" />
</Setter.Value>
</Setter>
</DataTrigger>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=ListBoxItem}, Path=IsSelected}"
Value="True">
<Setter TargetName="ContentPresenter"
Property="Content">
<Setter.Value>
<MarqueeTextBlock Text="{Binding Title}"
Style="{StaticResource AOTbMain_MARQUEE}"/>
</Setter.Value>
</Setter>
</DataTrigger>
</DataTemplate.Triggers>
</DataTemplate>
</AutoscrollListBox.ItemTemplate>
</AutoscrollListBox>
</Grid>
Solution 3
Or toggle the Visibility:
<Grid>
<AutoscrollListBox Name="Items" >
<AutoscrollListBox.ItemTemplate>
<DataTemplate>
<Grid>
<AutoscaleTextBlock x:Name="AutoscaleTextBlock"
Text="{Binding Title}"
Style="{StaticResource AOTbMain_MARQUEE}"
Visibilty="Visible" />
<MarqueeTextBlock x:Name="MarqueeTextBlock"
Text="{Binding Title}"
Style="{StaticResource AOTbMain_MARQUEE}"
Visibilty="Collapsed" />
</Grid>
<DataTemplate.Triggers>
<DataTrigger Binding="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType=ListBoxItem}, Path=IsSelected}"
Value="True">
<Setter TargetName="AutoscaleTextBlock"
Property="Visibility"
Value="Collapsed" />
<Setter TargetName="MarqueeTextBlock"
Property="Visibility"
Value="Visible" />
</DataTrigger>
</DataTemplate.Triggers>
</DataTemplate>
</AutoscrollListBox.ItemTemplate>
</AutoscrollListBox>
</Grid>
I need help,
when I click at datagrid at cell, I want to select all line like in image (please look at image), but without black border. how to disable, or change color to transparent? I tried this:
<DataGrid.Resources>
<Style TargetType="DataGridCell">
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="FocusVisualStyle" Value="{x:Null}"/>
</Style>
</DataGrid.Resources>
but don't work. nothing changes.
You need to style the selected cell not just cells. To do so you need to write this inside your style tag:
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="BorderThickness" Value="0"/>
</Trigger>
</Style.Triggers>
All you need was using Triggers hope it will work for you. Also you can change background for selected cell or whatever property you want.
Following example to customize wpf datagrid (border, cell corners, etc.). You can modify it as you wish.

When i select the row I am getting the Following Effect on grid.
I want Entire Row with light Blue color .
You can use using a TemplateBinding
<Border Name="DataGridCellBorder"
Background="{TemplateBinding Background}"/>
Previously I have faced same issue so I followed the following approach and it was worked fine for me. Once try it...
You are specifying some Width to the grid top Row right( You are using Buttons ) ? just give same width to the binding element i.e., if you are using Textblock give that width as same as its header thats it.
