Hii Friends

I am using Grid view to show data to user n my page

In grid page I have one search box when I try to bind data of searching then it not bind that data it bind all data. my code is as below any one please tell me what I am doing rong

public void gridbind()
    {
        DataSet ds = new DataSet();
        Master_Select objmaster = new Master_Select();

        objmaster.Select_Master(ds);
        GridView1.DataSource = ds;
        GridView1.DataBind();
    }

public void searchbind(string search_txt, string search_type)
    {
        
        if (search_type == "Name")
        {

            DataSet ds = new DataSet();
            //ds.Tables[0].Rows.Clear();

            Master_Search obj_search = new Master_Search();
            obj_search.Search_select_Master(ds_search, search_txt);
            GridView1.DataSource = ds_search;
            GridView1.DataBind();
        }
    }

gridbind (); method is for binding all data to grid

seaech_bind(); is for binding search result on grid

when I am using search then I get my searched data up to "ds_search" but it is not binding to grid view
