Try,

GridView1.DataSource = objDs.Tables[0];
 GridView1.DataBind();

There are two solutions: If DataSource of GridView is Dataset then you have to set DataMember (tableName) property.

GridView1.DataSource=objDs;
GridView1.DataMember="TableName";
GridView1.DataBind();

Or

If you don't know the exact name datamember then use DataTable instance. objDs.Tables[0] return the reference of DataTable object.

GridView1.DataSource = objDs.Tables[0];
 GridView1.DataBind();
