How can I clear rows in DataGridView with C#?

I am using gridview to show details of some of my data. The flow is like this: when a dropdown value is changed, the data in the gridview is bound according to the selected value. Now when there is no data corresponding to that value, I need to clear the gridview. For this I use:

gridview1.Rows.Clear()

But when I compile my code, an error is generated:

System.Web.UI.WebControls.GridViewRowCollection' does not contain a definition for
'Clear' and no extension method 'Clear' accepting a first argument of type
'System.Web.UI.WebControls.GridViewRowCollection' could be found (are you missing
a using directive or an assembly reference?)

I have also given the reference:

using System.Web.UI.WebControls;

Now how should I clear the gridview?

Thanks in advance.

You can bind the GridView with null, or with a new DataSource.

gridview1.DataSource = null;
gridview1.DataBind();
