Question

So, I have a GridView with an ObjectDataSource, and I want to programmatically set one of the SelectParameters of the ObjectDataSource.

I tried (during both Page_Load and DropdownList__SelectedIndexChanged)

objectDataSource.SelectParameters["my_parameter"].DefaultValue = "my_value";
objectDataSource.DataBind();

but it didn’t work. What would you suggest?

Trap the onselecting event on the datasource.

protected void ObjectDataSource1_Selecting(object sender, ObjectDataSourceSelectingEventArgs e)
{
    e.InputParameters["month"] = DateTime.Now.Month;
}
