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

First check your query.It returns any dataset.Run that query in Sql Query Analyzer.

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

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.

Hi,
why are you using m_DataSet.DefaultViewManager anyhow?
I always use things like...
Dataset ds = GetDataset();
Gridview.Datasource = ds.Tables[0];
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...)

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
<asp:gridview id="ProductDG" runat="server" autogeneratecolumns="false" allowpaging="true" pagesize="10" height="182px" width="155px" > <columns>
<asp:boundfield datafield="'Column name" headertext="Name"><br>
</asp:boundfield>
</columns>
</asp:gridview>

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.

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

Dear You set Datasource but you need to bind Datagrid after that
ProductDG.DataBind()
Also If someone tells you to post code then post your complete code.
<asp:boundfield datafield="column Name" headertext="Name" sortexpression="column Name" ></asp:boundfield>
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

Dim m_DataAdapter As New SqlClient.SqlDataAdapter( _<br />
"query", "connectionstring")<br />
<br />
Dim m_DataSet As New DataSet<br />
' Fill the DataSet.<br />
m_DataAdapter.Fill(m_DataSet)<br />
<br />
' Bind the DataGrid to the DataSet's first DataTable.<br />
ProductDG.DataSource = m_DataSet<br />
ProductDG.DataBind();

The problem with you code is
1.
Rock Star. wrote: m_DataSet.DefaultViewManager
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.
