Rock Star

Hi all, I am trying to bind teh datagird with a datset at run time I tried the following code but I m not getting any data in datagrid. Can anyone please provide me the correct code. The code is Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim Productds As New DataSet Dim m_DataAdapter As New SqlClient.SqlDataAdapter( _ "query", "connectionstring") Dim m_DataSet As New DataSet ' Fill the DataSet. m_DataAdapter.Fill(m_DataSet, "Demo") ' Bind the DataGrid to the DataSet's first DataTable. ProductDG.DataSource = m_DataSet.DefaultViewManager ProductDG.DataMember = "Demo" End sub Thanking You!

May be you missed something, ' Bind the DataGrid to the DataSet's first DataTable. ProductDG.DataSource = m_DataSet.DefaultViewManager ProductDG.DataMember = "Demo" ProductDG.DataBind()

Hi, I checked my query its perfect. I checked dataset.tables(0).rows.count and its returning number of rows in the dataset. I dont everywhere same code is given to bind the datagrid to dataset. I dont know why it is not working in my case.

ProductDG.DataSource = m_DataSet.DefaultViewManager Is there any reason to use DefaultViewManager. You can also do in this way. ProductDG.DataSource = m_DataSet.Tables[0] or If m_DataSet.DefaultViewManager <> Nothing Then //bind DataGrid Else //Is null End If Regard Khan

hi I tried ProductDG.DataSource = m_DataSet.Tables[0] in my code but same result. I cant see my datasrid control. But when I am trying to put the condition for m_DataSet.DefaultViewManager <> Nothing it is going in the else part and showing nothing for defaultviemanager.

Try like,

' Bind the DataGrid to the DataSet's first DataTable.
ProductDG.DataSource = m_DataSet.Tables("Demo")
ProductDG.DataBind()

Tell me one thing... Does your DataGrid has columns bounded? Could you please post your *.aspx HTML?

Yes my datagrid has one bounded column in .aspx file but wen i run the page I am getting an error for "A field or property with the name 'Column name' was not found on the selected data source." but my table has the column I have specified in bond column section of datagrid. This is the aspx code for datagrid

Its a typing mistake there is no single quote in the code. Do u know why there is no data in my data grid.

Use a datatable instead of dataset. and try the GV is displaying or not.

I tried data table too but same result.

can you please do a copy paste of the gridview HTML code and the vb code. So that I can simulate the same thing and find out the problem.

Hi, why are you using m_DataSet.DefaultViewManager anyhow? I always use things like...

Dataset ds = GetDataset();
Gridview.Datasource = ds.Tables[0]; // Even with a .CreateDataReader if you want to
GridView.Databind();

And works perfectly fine. I assume the GridView is visible on the aspx marking right? (Sorry for this obvious question, but you never know...)

This is the aspx code u asked for <asp:GridView ID="ProductDG" runat="server" AutoGenerateColumns=false AllowPaging="true" PageSize=10 Height="182px" Width="155px"> <Columns> <asp:BoundField DataField="column Name" HeaderText="Name" SortExpression="column Name" > <HeaderStyle Font-Names="Arial" Font-Size="12px" /> <ItemStyle Font-Names="Arial" Font-Size="12px" /> </asp:BoundField> </Columns> </asp:GridView> and this is the vb code for the databinding Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim Productds As New DataSet Dim m_DataAdapter As New SqlClient.SqlDataAdapter( _ "query", "connectionstring") Dim m_DataSet As New DataSet ' Fill the DataSet. m_DataAdapter.Fill(m_DataSet, "Demo") ' Bind the DataGrid to the DataSet's first DataTable. ProductDG.DataSource = m_DataSet.DefaultViewManager ProductDG.DataMember = "Demo" End sub

Here you used "column name" but you should post with column field name which you want to bind Now dont tell that you did mistake here to post code regard kHan please don't forget to vote on the post that helped you.

Try this, It is working for me. Dim Productds As New DataSet Dim m_DataAdapter As New SqlClient.SqlDataAdapter( _ "query", "connectionstring") Dim m_DataSet As New DataSet ' Fill the DataSet. m_DataAdapter.Fill(m_DataSet) ' Bind the DataGrid to the DataSet's first DataTable. ProductDG.DataSource = m_DataSet ProductDG.DataBind();

The problem with you code is 1.

You can directly use m_DataSet or one table inside the dadta set 2. Like Pathan told You are not binding the grid view. using ProductDG.DataBind() So when i told you to use datatable you used it but you didnot bind it to GV. I think now you got the problem.
