URGENT & EASY ASP using C# populating datagrid
I am having a hard time getting my datagrid to show my data. What do I need to do to make this work?
I am using .NET 2008
I removed parts of my connection string but it does connect
I would really like to put the data in an object instead so if you have an example of that that would be great as well

Hi , i have used your code and its working fine for me.. The fiffrence is in the aspx page.
aspx...
<asp:GridView runat="server" ID="GridView1" AutoGenerateColumns="False " >
<Columns>
<asp:BoundField DataField="a" HeaderText="a" SortExpression="a" />
<asp:BoundField DataField="b" HeaderText="b" SortExpression="b" />
<asp:BoundField DataField="c" HeaderText="c" SortExpression="c" />
<asp:BoundField DataField="no" HeaderText="no" SortExpression="no" />
<asp:BoundField DataField="x" HeaderText="x" SortExpression="x" />
<asp:CheckBoxField DataField="bol" HeaderText="bol" SortExpression="bol" />
</Columns>
</asp:GridView>
aspx.cs
protected void Page_Load(object sender, EventArgs e)
{
SqlConnection sqlConn = new SqlConnection(Configuratio nManager.C onnectionS trings["Dy namics-Exc hangeConne ctionStrin g"].ToStri ng());
try
{
GridView1.DataSource = null;
SqlCommand sqlComd = new SqlCommand();
sqlComd.Connection = sqlConn;
sqlComd.CommandType = CommandType.Text;
sqlComd.CommandText = "select * from a";
SqlDataAdapter da = new SqlDataAdapter();
DataSet ds = new DataSet();
da.SelectCommand = sqlComd;
da.Fill(ds, "DEPT_FEED");
DataTable dt = new DataTable();
dt = ds.Tables["DEPT_FEED"];
DataView dv = new DataView(dt);
dv = ds.Tables["DEPT_FEED"].Def aultView;
GridView1.DataSource = dv;
GridView1.DataBind();
foreach (DataTable t in ds.Tables)
{
Response.Write("Table: " + t.TableName + " is in Dataset");
Response.Write("Row 0, Column 2: " + t.Rows[0][2]);
Response.Write("Row 1, Column 2: " + t.Rows[1][2]);
Response.Write("Row 2, Column 2: " + t.Rows[2][2]);
Response.Write("Row 3, Column 2: " + t.Rows[3][2]);
}
}
catch
{
}
finally
{
sqlConn.Close();
}
}
I have used a Sql Database and you have used Oracle Database, but it doesnt matter. I have taken a diffrent table(dummy table).
You can try the code that i have pasted in aspx...... its only the Datafield.

DataFied= "Feed_Name" is missing in your gridview
That is the reason no data is shown in the gridview
