WPF c# datagrid set individual row height

I am pretty new to WPF and C#. I am trying to create a datagrid where I can programmatically set the height of the individual rows.

It seems possible to change the height for all the rows together, but I would like the rows to have different heights from each other.

Does anyone know a way to accomplish this? (I was thinking I could set the row height to automatic, and put an invisible TextBox in an unused column. I could change the height of the unused TextBox programmatically.)

Use a DataTrigger. The code below switches between Height="Auto" and Height="*". It is important that the Height is not set in the RowDefinition but in the style.

        <RowDefinition>
            <RowDefinition.Style>
                <Style TargetType="RowDefinition">
                    <Setter Property="Height" Value="Auto" />
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding MyFlag}" Value="True">
                            <Setter Property="Height" Value="*" />
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </RowDefinition.Style>

EKrueger,

Thank you very much for your response.

Your technique however, only happens when the datagrid is created. I need something that I can call at different times so I can resize my rows on a regular basis.

I kept searching and here is the solution I found.

Cheers.

    private void resizeDataGridRowHeight() {
    int a = boundDataGrid.Items.Count;
    int calibrationRowHeight = 28;
    for (int i = 0; i < a; i++) {
        myRowHeight = ListofObjectsThatEachRepresentAParameter.ListOfDataTableRows[i].ListOfCalibrationRows.Count * calibrationRowHeight;
        DataGridRow row = boundDataGrid.ItemContainerGenerator.ContainerFromIndex(i) as DataGridRow;
        row = boundDataGrid.ItemContainerGenerator.ContainerFromIndex(i) as DataGridRow;
        row.Height = myRowHeight;
    }
}

The easiest thing is probably to handle this in the DataGrid.LoadingRow event which is raised right after a row is instatiated.

To do so just add an event handler to your datagrid in the xaml code:

<DataGrid LoadingRow="DataGrid_LoadingRow"></DataGrid>

And declare this eventhandler in your code to manage the row height individually via the Height property:

private void DataGrid_LoadingRow(object sender, DataGridRowEventArgs e)
{
    DataGridRow row = e.Row;
    row.Height = 50; //put your height here
}
