hi paps, you're not actually instantiating any GridColumnStyles in your code. you're just trying to set the width of empty array elements. (GridColumnStyles(0), GridColumnStyles(1), GridColumnStyles(2) etc.) this is the raeson for the exception. you can try doing this with the vs.net designer as well. just look at the TableStyles property of the datagrid from the properties window. you can set this up so that it's created in the initialization routine of the form rather than manually writing the code for it. take advantage of the code generation module and save yourself a case of carpal tunnels syndrome. :) hope this helps.

When I set the prefered col width to 200 all the other columns too take the same width. How do I specify the 2nd col with a different width. Tnx

hi paps, the preferred width property is on the tablestyle object. this will set the width of any columnstyle in the tablestyles gridcolumnstyles property that has a width value of 0. if you set the width property of the columnstyle, the width of that column will be set accordingly. hope this helps.

hi paps, the gridcolumnstyles property belongs to the tablestyles property of the datagrid. so if you are doing this through the designer, have a look at the properties of the datagrid, find the tablestyles property and click the ellipsis button [...]. this should open the tablestyles editor dialog. next look for the columnstyles property in this dialog and click the ellipis button. this will open the columnstyles editor. hope this helps.
