网格列和列定义WPF之间的连接

Question

First of all, I am new to WPF and I am trying to find the proper approach to dynamically resize Column Definitions of a Grid

  <Grid x:Name="uxFootbarGrid" Height="40" Margin="0" VerticalAlignment="Bottom">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="7*"/>
                        <ColumnDefinition Width="8*"/>
                        <ColumnDefinition Width="105*"/>
                    </Grid.ColumnDefinitions>
                    <Grid x:Name="uxOrderStatusGrid" Margin="0" d:LayoutOverrides="LeftMargin, RightMargin, TopMargin, BottomMargin">
                        <TextBox Margin="0" TextWrapping="Wrap" Text="Status: CMP" VerticalContentAlignment="Center" Background="{x:Null}" BorderThickness="0" Foreground="White" Grid.Column="1"/>
                    </Grid>
                    <Grid Grid.Column="1" Margin="0" d:LayoutOverrides="LeftMargin, RightMargin, TopMargin, BottomMargin">
                        <TextBox x:Name="uxProcessingTextBox" Margin="0" Grid.Column="2" TextWrapping="Wrap" Text="Processing: D" Background="{x:Null}" Foreground="White" VerticalContentAlignment="Center" BorderThickness="0" TextChanged="uxProcessingTextBox_TextChanged"/>
                    </Grid>

                </Grid>

I have Grids inside of Grid. I am trying programatically to find the connection between those.

The idea is:

foreach(column in masterGrid)
{
   getAllTextBoxes()
   getTotalWidth()
   setWidthToColumnDefinitionOfMasterGrid()
}

All good at the moment, but I cannot find relation between Control and the Column Definition they belong to.

Answer 1

In order to find out which column an element is in, use the Grid class:

int columnIndex = Grid.GetColumn(elementName);

In order to access the respective column, access the collection of column definitions on the grid:

ColumnDefinition myColumn = uxFootbargrid.ColumnDefinitions[columnIndex];

Once you have the ColumnDefinition, you can go ahead and change the properties you want
