asp.net DataGrid with DropDownList error

[mariacri11]

I have a page wich does the following:
I select a value from a DropDownList and I press a button.
The DataGrid displays values based on the selected value.

It works fine until I select a value which shoult display less pages then the previous selection.

In this case I get the following error:

System.Web.HttpException: Invalid CurrentPageIndex value. It must be >= 0 and < the PageCount.

I tried to write code on the button so that i return to the first datagrid page before executing the databind.
But PageCount property is read only .

Thanks!

Maria,

In the event handler for your button, you should reset the current page index to 0 before re-binding your DataGrid:

// within your button event handler
DataGrid.CurrentPageIndex = 0;
