How change data grid view datasource with ObjectDataSource?

Question

I have two ObjectDataSources in my form.i want change data grid view datasource with ObjectDataSources.

Button's eventhandler to change ObjectDataSource1 is :

protected void lbnChangeInfo1_Click(object sender, EventArgs e)
{
    gdvList.DataSource = null;
    gdvList.DataBind();
    gdvList.DataSource = odsWork1;
    gdvList.DataBind();
}

Button's eventhandler to change ObjectDataSource2 is :

protected void lbnChangeInfo2_Click(object sender, EventArgs e)
{
    gdvList.DataSource = null;
    gdvList.DataBind();
    gdvList.DataSource = odsWork2;
    gdvList.DataBind();
}

When executed, this error is thrown:

Additional information: Both DataSource and DataSourceID are defined on 'gdvList'. Remove one definition.
