Thanks for your help I find the resolution for the problem. I needet to this
gvErot12 = generateBoundField(datatable, gvErot12);
private GridView generateBoundField(DataTable dt,GridView gv)
{
//Iterate through the columns of the datatable to set the data bound field dynamically.
foreach (DataColumn col in dt.Columns)
{
//Declare the bound field and allocate memory for the bound field.
BoundField bfield = new BoundField();
//Initalize the DataField value.
bfield.DataField = col.ColumnName;
//Initialize the HeaderText field value.
bfield.HeaderText = col.ColumnName;
//Add the newly created bound field to the GridView.
gv.Columns.Add(bfield);
}
return gv;
}
this returns the gridview back to the main program and there
gvErot12.DataSource = datatable;
gvErot12.DataBind();
thanks for quideance!!!!!!!

hi this is wat the books says:
It uses the supplied SQL membership provider to manage the user database.
If you want to extend the application so that it tracks additional
data besides the user name, password, and the secret question and
answer, or if you want to use your own database to store the member
information, you can code your own provider. For most applications,
however, the supplied provider should be adequate.
however i would like to connect it to my own sql membership provider anyone know what i should change?

**********
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Page.IsPostBack = False Then
LoadClientSite()
End If
End Sub
*******
Private Sub LoadClientSite()
Dim ds As New Data.DataSet
Dim objdata As Businesslayer.ClientSite = New Businesslayer.ClientSite
ds = objdata.GetUsers
cmbClientSite.DataSource = ds
cmbClientSite.DataBind()
cmbClientSite.Items.Add(New ListItem("Select Client Site", ""))
cmbClientSite.Items.Item(cmbClientSite.Items.Count - 1).Selected = True
End Sub
*******
My class
Public Function GetClientSite() As Data.DataSet
Dim strSQL As String
Dim obj As Datalayer.Database = New Datalayer.Database
strSQL = "Select Client_id,Client_site from ClientSite(nolock) "
GetClientSite = obj.GetDataSet(strSQL)

Oga M wrote: ds = objdata.GetUsers
You are calling function GetUsers... but you have function called as 'GetClientSite()'
Oga M wrote: Public Function GetClientSite() As Data.DataSet
Which is correct ??? Atleast both function name should be same.

when u are buiding at run time and u have assigned property to control that's problem.
CONTROL-PROPERTY
DataTextField=ClientSite
DataValueFielld_ClientSite_Id
it's wrong,
u have to bind your drop down as per below.
cmbClientSite.DataSource = ds
cmbClientSite.DataTextField="ClientSite"
cmbClientSite.DataValueField ="ClientSite_Id"
cmbClientSite.DataBind()
cmbClientSite.Items.Add(New ListItem("Select Client Site", ""))
cmbClientSite.Items.Item(cmbClientSite.Items.Count - 1).Selected = True
it will work..
Thanks,

try this code it is working.
this is on the form:
Public Sub Pop_Type()
Dim NURDAtaset As New DataSet
Try
Call GetCommandObject1("Pop_Type")
Dim NURAda As New SqlDataAdapter(cmd)
NURAda.Fill(NURDAtaset)
If NURDAtaset.Tables(0).Rows.Count <> 0 Then
For Each row As DataRow In NURDAtaset.Tables(0).Rows
CmbType.Items.Add(row("TypeName").ToString)
Next
End If
Catch ex As Exception
Finally
NURDAtaset.Dispose()
NURCon.close()
cmd.Dispose()
End Try
End Sub
This is in common class:
Public Function GetCommandObject1(ByVal strQuery As String) As SqlCommand
Try
cmd = New SqlCommand
cmd.Connection = SharedCon.Siteconnection
cmd.CommandType = CommandType.StoredProcedure
cmd.CommandText = strQuery
Return cmd
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Function
if there is some confusion then ask.

I want to use a dropdownlist server control with a datagrid server control sothat when i change the dropdownlist the grid changes but using AJAX. I can do it if the datagrid is a simple html table but i can't implement it if the grid is a server control datagrid. Is there anyway to display the grid as a server control using AJAX or it must be html table to display it with AJAX?

Hi All,
I need to have some clarifications regarding a web project in ASP.net. I need to design a project for a form called project information form(PIF). Th constraint on that being I should be using a treeview to navigate to different screens(subsections in the form). I am dynamically creating a treeview from database values, because some of the screens need to be reused across subtrees. for example, there is building information in treenodes and the subnodes of those treenodes have area information. The area information forms(aspx pages) are similar for each building. so i am just calling the same form for each area, and planning to store the values filled in using the building and area id session variables. Q1)is there a better way to save this info? because the form(PIF) is huge and might need DAYS to be filled completely. I know that I might have problems with my session expire. but then I cannot provide a save button in each aspx page.. (thr are more than a 100 screens with data to be filled in)and the amount of data is also huge for session variables..Do i create a temporary table in the backend itself to store the data before the complete form is filled? so that when the final release is done I can save it to the master Database. In that case where can I trigger an auto-save? and since it is a tree, the navigation could be from any node to any other node, meaning they can fill the forms randomly. I am confused with where to trigger a save event automatically.
Any help.. thanks in advance
Please let me know abt any other designs where this problem couls be overcome
Regards
Vineeth

Here are a few ways
Very Basic method of adding new node
<br />
private void BuildMenu()<br />
{<br />
<br />
tview.Nodes.Add("Item1");<br />
tview.Nodes.Add("Item2");<br />
tview.Nodes.Add("Item3");<br />
tview.Nodes.Add("Item4");<br />
<br />
}<br />
Slighty more complex
<br />
private void BuildMenuNodes()<br />
{<br />
AddNewNode("Item1", tview);<br />
AddNewNode("Item2", tview);<br />
AddNewNode("Item3", tview);<br />
AddNewNode("Item3", tview);<br />
<br />
}<br />
Even More Complex way
<br />
<br />
private void AddNestedNodes()<br />
{<br />
TreeNode node;<br />
<br />
node = tviewExplorer.Nodes.Add("Security");<br />
node.Nodes.Add("Item1");<br />
node.Nodes.Add("Item2");<br />
node.Nodes.Add("Item3");<br />
<br />
node = tviewExplorer.Nodes.Add("Item1");<br />
node.Nodes.Add("Item A");<br />
node.Nodes.Add("Item B");<br />
node.Nodes.Add("Item C");<br />
<br />
}<br />
// This is the MS prefered method due to the performance gains
<br />
<br />
private void AddNodesRange()<br />
{<br />
TreeNode[] nodes = new TreeNode[3];<br />
<br />
nodes[0] = new TreeNode(""ItemA");<br />
<br />
nodes[0].Nodes.Add("Item2");<br />
nodes[0].Nodes.Add("Item3");<br />
nodes[0].Nodes.Add("Item4");<br />
<br />
nodes[0] = new TreeNode(""ItemB");<br />
<br />
nodes[0].Nodes.Add("Item5");<br />
nodes[0].Nodes.Add("Item6");<br />
nodes[0].Nodes.Add("Item7");<br />
<br />
nodes[0] = new TreeNode(""ItemC");<br />
<br />
nodes[0].Nodes.Add("Item21");<br />
nodes[0].Nodes.Add("Item31");<br />
nodes[0].Nodes.Add("Item41");<br />
<br />
<br />
tviewExplorer.Nodes.AddRange(nodes);<br />
<br />
<br />
}<br />
