Dont use sqlReader,instead use Datatable to bind your data in your GridView

Solution 1

Try this:

C#

SqlCommand = new SqlCommand(query, conn);
SqlDataAdapter da=new sqldataadapter(SqlCommand );
Dataset ds=new Dataset();
da.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
reader.Close();

If you want at page load just load the Grid "SELECT Reg_No,convert(nvarchar(10),Reg_Date,103) as Reg_Date, Patient_Name, Contact_No, Department_Name, convert(nvarchar(10),Date,103) as Date, Advance_Amt FROM In_Patients" by this Query,

if you want bind data to GridView By using SqlDataReader

SqlDataReader will returns the Row of data

So you want add row by row to table(create one new table)
then finally bind the Table data into your GridView.

or else u can use

SqlDataAdapter da=new sqldataadapter(query, conn);
Dataset ds=new Dataset();
da.Fill(ds);
GridView1.DataSource = ds;
GridView1.DataBind();
