Column Width

This sample shows how you can use XAML-style star sizing to implement flexible layouts with the FlexGrid. Star sizing is specified in the width property of the Column object. Star sizing is similar to percentage sizing, except that the values do not have to add up to one hundred. A width of '3' means 'three times wider than 1.' The total size used to calculate the layout is the current width of the control minus the width of any non-star columns divided by the number of stars specified.

In this case, we set the width of the second column to * to achieve that effect.</p> <p> We also set the minimum width of the second column to 100 pixels in order to prevent it from getting too narrow when the other columns in the grid are resized, and we prevent users from resizing this column with the mouse.</p> <div id="theSecondGrid"></div> <br /> <br /> <h4> Example 3:</h4> <p> This example sets all widths to *, which means the space available is divided equally among them. Resize the browser and notice how the grid resizes and the columns fill it up equally. </p> <p> Also, unlike the other examples, this one sets the allowResizing property of the entire grid rather than an individual column. We set this one to None, but you may also choose Columns, Rows, or Both.</p> <div id="theThirdGrid"></div> </div> </body> </html>
