I want to use a three-column datagrid so that the user can enter the data into it and then store the data from the datagrid into the database.
But my problem is that I created DataGrid but I can't enter any data.

HorizontalContentAlignment="Center" HorizontalAlignment="Center"
IsEnabled="{Binding ElementName=chkitems, Path=IsChecked}"

<DataGrid.Columns>
<DataGridTextColumn Header="نام کالا" Width="250" FontSize="14" Binding="{Binding name}"/>
<DataGridTextColumn Header="تعداد" Width="80" FontSize="14" Binding="{Binding number}"/>
<DataGridTemplateColumn Header=" ">

If you plan to display collection content, UWP provides GridView and ListView controls.
like this:
xaml.cs
public ObservableCollection<string> TestCollection {get; set;}
xaml
<GridView ItemsSource="{x:Bind TestCollection}"/>
If you plan to display a ListView or GridView in the DataGrid, you can try to put the control in RowDetail. like this:
<controls:DataGrid ...>
...
<controls:DataGrid.RowDetailsTemplate>
<DataTemplate>
<Grid>
<GridView ItemsSource="{Binding Atores}">
</GridView>
</Grid>
</DataTemplate>
</controls:DataGrid.RowDetailsTemplate>
...
</controls:DataGrid>

How to: Display and Configure Row Details in the DataGrid Control
Best regards.
I have a DataGrid with 10-15 columns which can have around 100-200 rows. The datagrid is placed within a Tab control ( which is not in focus by default ).
I tried to virtualize the DataGrid but when I click the tab containing the DataGrid, the program freezes for like 4-5 seconds, and then the tab opens displaying the datagrid. After that the rows seem to scroll fast which is good, but the columns still behave slow like un-virtualized.
When I remove the code to virtualize (last 4 options in DataGrid tag), the grid displays immediately but scrolls very slow and lags.
The following is my datagrid code:
<DataGrid Name="xDataGridFieldConfig"
FrozenColumnCount ="1"
HorizontalAlignment="Stretch"
HorizontalContentAlignment="Stretch"
VerticalAlignment="Stretch"
Style="{DynamicResource FieldConfigDataGridHeaderStyle}"
AutoGenerateColumns="False"
CanUserResizeColumns="False"
CanUserResizeRows="False"
CanUserReorderColumns="False"
SelectionMode="Single"
GridLinesVisibility="Horizontal"
HorizontalGridLinesBrush="#cbcaca"
HeadersVisibility="Column" ItemsSource="{Binding FieldConfigCollection}"
VerticalScrollBarVisibility="Auto"
HorizontalScrollBarVisibility="Visible"
VirtualizingPanel.IsVirtualizingWhenGrouping="True"
VirtualizingPanel.VirtualizationMode="Standard"
VirtualizingPanel.IsVirtualizing="True"
ScrollViewer.CanContentScroll="False">
<DataGrid.Columns>
<DataGridTextColumn Header="S No." Binding="{Binding Path=ID}" IsReadOnly="True" Width="80"/>
<!-- using template for custom checkbox -->
<DataGridTemplateColumn Header="EN" IsReadOnly="False">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<flatcheckbox:FlatCheckBox x:Name="xFlatCheckBoxFieldConfigEN" Margin="0" IsChecked="{Binding Path=Enabled, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>

</DataTemplate>
</DataGridTemplateColumn.CellEditingTemplate>

<DataGridTemplateColumn Header="Group" Width="150">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Name="xTextBlockFieldConfigGroup" Text="{Binding Path=Group, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
</DataTemplate>

Is there anything wrong I'm doing ? How to make the datagrid to be displayed immediately as soon as I open the tab.
Can we bind the image column from a different source and the other columns from the datatable?
<DataGrid x:Name="GridViewProducts" Margin="80,30,0,0"
AutoGenerateColumns="True" BorderThickness="12"
BorderBrush="PaleTurquoise" ItemsSource="{Binding}" Height="200"
Width="745" HorizontalAlignment="Center"
HorizontalContentAlignment="Center"
VerticalContentAlignment="Center"
VerticalAlignment="Center" MouseEnter="GridViewProducts_MouseEnter" >
<DataGrid.Columns>
<DataGridTemplateColumn DisplayIndex="0"
x:Name="imageColumn">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Image x:Name="image_Grid_Column"
Source="{Binding ImageSource}" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
I'm trying to put a picture in my DataGrid. So I used a DataGridTemplateColumn but the Result is "glitchy".
Here is my wpf extract code :
<DataGrid MinRowHeight="24" x:Name="ListFamily" Grid.Column="1"
Margin="2" VerticalContentAlignment="Stretch"
HorizontalContentAlignment="Stretch"
AutoGenerateColumns="False" IsReadOnly="True"
SelectionChanged="ListFamily_SelectionChanged"
CanUserReorderColumns="False"
CanUserSortColumns="False" Grid.Row="1">
<DataGrid.Columns>
<!-- some datagridcolumn -->
<DataGridTemplateColumn Width="Auto" CanUserResize="False" IsReadOnly="True">
<DataGridTemplateColumn.Header>
<Label Content="{x:Static res:StringResources.language}" ToolTip="{x:Static tt:TooltipStrings.language}" HorizontalContentAlignment="Stretch"/>
</DataGridTemplateColumn.Header>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Image Source="{Binding Language, Converter={StaticResource StringToPicture}}" Height="{Binding RowHeight, ElementName=ListFamily}" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Stretch="Uniform"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
<DataGridTemplateColumn.CellStyle>
<Style>
<Setter Property="FrameworkElement.VerticalAlignment" Value="Center"/>
</Style>
</DataGridTemplateColumn.CellStyle>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
and here is what I get :
I triend to bind RowHeight of the DataGrid but without luck. Any ideas ?
Thanks

Using this code is working :
<DataGridTemplateColumn Width="Auto" CanUserResize="False" IsReadOnly="True">
<DataGridTemplateColumn.Header>
<Label Content="{x:Static res:StringResources.language}" ToolTip="{x:Static tt:TooltipStrings.language}" HorizontalContentAlignment="Stretch"/>
</DataGridTemplateColumn.Header>
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Image Source="{Binding Language, Converter={StaticResource StringToPicture}}" Stretch="Uniform"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
In my WPF project a DataGrid is bound to a collection. When DataGrid row selection changes the corresponding TextBox, should get updated. The DataGrid selected item is bound to a property
SelectedItem="{Binding CardType.SelectedCard}"
and corresponding Text box is bound
Text="{Binding CardType.SelectedCard.LimitBalance}"
so when a selected item is changed, my text box will get updated.
