I want to display the 5th, 10th, 15th, 20th, etc anniversaries of the current year. Therefore instead of writing multiple SqlDataSource which would only differ in the WHERE clause (WHERE anniversary=5, WHERE anniversary=10, etc) I would like to use a parameter to have only one SqlDataSource which then returns the x-th year anniversaries (WHERE anniversary=@years). While the SQL statement works pretty fine, I am facing problems how to bind this one SqlDataSource to the different DataGrids (one Grid for the 5th year anniversaries, second Grid for the 10th year anniversaries, etc.) and setting the parameter. I tried to assign an OnDataBinding event for the DataGrids where I set the SelectParameter[0].DefaultValue to 5, 10, etc. but this does not work but the whole VWD is crashing (I guess all DataGrids start binding the same time when the page starts loading but not one after another).
