问题描述
大家好,
我对.net中的层体系结构模型来说还很陌生,我的问题是
单击提交"按钮后在文本框中输入用户名时,单击提交"按钮后,我必须显示网格视图,而不是显示数据库中的值.
这是我的代码:
DAL:
hi to all,
i''m pretty new to tier architecture model in .net and my problem is
when a username is given in the textbox after clicking the submit button i have to display the grid view when i''m clicking the submit button the grid is displaying but not the values from the database.
here is my code:
DAL:
public DataSet UserDetailGrid(BEL.BEL objBELUserDetailGrid)
{
con.Open();
SqlCommand cmd = new SqlCommand("Usp_GridUserDetails", con);
cmd.CommandType = CommandType.StoredProcedure;
try
{
DataSet ds = new DataSet();
cmd.Parameters.AddWithValue("@UserName", objBELUserDetailGrid.UserNam);
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);
con.Close();
return ds;
}
catch (Exception ex)
{
throw ex;
return null;
}
finally
{
cmd.Dispose();
con.Close();
con.Dispose();
}
}
BLL:
BLL:
public DataSet UserGridDetail(BEL.BEL objUserDetails)
{
DAL.DAL UDGrid = new DAL.DAL();
DataSet ds = UDGrid.UserDetailGrid(objUserDetails);
return ds;
}
InCodeBehind:
InCodeBehind:
protected void BtnDetails_Submit_Click(object sender, EventArgs e)
{
Grd_Details.Visible = true;
BL.BLL objgridviewdetail = new BL.BLL();
BEL.BEL objGUDBEL = new BEL.BEL();
objGUDBEL.UserNam = TxtDetails_UserName.Text;
DataSet ds = objgridviewdetail.UserGridDetail(objGUDBEL);
Grd_Details.DataSource = ds;
Grd_Details.DataBind();
}
推荐答案
change
Grd_Details.DataSource = ds;
到
to
Grd_Details.DataSource = ds.Tables[0];
