    <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="*"></RowDefinition>

                    <RowDefinition Height="auto"></RowDefinition>
                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*"></ColumnDefinition>
                    <ColumnDefinition Width="*"></ColumnDefinition>
                </Grid.ColumnDefinitions>

                <!--Isim-->
                <Entry Grid.Row="0" Grid.Column="0" Visual="Material" Placeholder="Isim" />
