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.

Harini

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..

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

Hi,
Is any know how to add element to tree view or update elements to treeview using Client Call back concept.

Is any know how to add element to tree view or update elements to treeview using javascript.

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 />
        // Add Nested Nodes<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 />

Hi,
I want some instructions in converting existing C# Windows Application to C# Web Application..

Please post your replies as soon as possible.

Please do not cross post...

I found a living worth working for, but haven't found work worth living for.

If the application has been properly architected it should just be a matter of rewriting the presentation (UI) layer - perhaps with the odd addition elsewhere to support a stateless model of working. If it hasn't been well architected then you are looking at rewriting the whole application.

Hello, I posted an earlier question about missing codebehind files, which I have since had answered.

I have an Aspnet 1.x website with .aspx and .dll files on the server; the codebehind files are not on the server, and the previous developer has neglected to leave any source code behind.

I have used Lutz Roeder's Reflector program to decompile the .dll, and now I can see all the juicy codebehind for each of the pages of the website.

My question now is this:

I want to make some minor changes to validation code. Can I take all the VB code reconstructed by Reflector, pour it into a new Codebehind page with the changes I want to make, and recompile just that page?

This seems pretty straitforward, but I want to be sure I am not about to find a pitfall. Will I need to reconstruct all the VB codebehind pages for the whole site for it to recompile, or is one page ok?

Thanks!

if u are having .aspx file same name as codebehind files as u are having from .dll then u can do it in this way. open application then click on .aspx page to view codebehind if it's coming blank then just copy paste all code for .vb file in this file. and then just compile it. done.

u can do it with one page only also.

Thanks,
Sun Rays

Thanks very much for your reply!

Yes that sounds pretty much what I need to do -- the app works, so the old code behind has all been compiled into .dll and works. I just wanted to be sure that if I reconstruct just one codebehind file as you say, and recompile, the app won't need all the other 30 codebehinds reconstructed as well.

Thanks again!

i have created a simple activex control.
it loads successfuly on the aspx page. it displays its user interface as created. ( one text box and a command button )

following is the vb6 code for the activex control

Option Explicit
Dim displaytext_value As String

Private Sub Command1_Click()
Text1.Text = displaytext_value
End Sub

Public Property Get displaytext() As String
displaytext = displaytext_value
End Property

Public Property Let displaytext(ByVal vNewValue As String)
displaytext_value = vNewValue
End Property

Private Sub UserControl_ReadProperties(PropBag As PropertyBag)
displaytext_value = PropBag.ReadProperty("displaytext", "")
End Sub

Private Sub UserControl_WriteProperties(PropBag As PropertyBag)

PropBag.WriteProperty "displaytext", displaytext_value, ""

End Sub

-----------------------------------------
following is the aspx page code

<object style="Z-INDEX: 110; LEFT: 304px; WIDTH: 176px; POSITION: absolute; TOP: 296px; HEIGHT: 176px"
="" codebase="TestCtl.ocx" classid="clsid:4C86F415-A10F-4785-B7D0-549A37D20F08" viewastext="">
<param name="_ExtentX" value="4657" />
<param name="_ExtentY" value="4657" />
<param name="displaytext" value="this is a test control" />

-------------Now the Problem ----------------------------

this control is loaded in the page when its opened in the web browser.

But on click of the command button , value of displaytext property i.e.
"this is a test control" should be displayed in the textbox.
and that is Not Happening.

if i use this control in vb.net windows application. it works and value is displayed

Any Suggestions.

Thanks

Hi guys,

I am very glad to be here. I have a doubt.I have used
window.close(); in javacsript to close a web page. It works fine but it asks for a confirmation/ it displays a message box. But i don't want this message box to be poped up. Is there any way to exclude this message box?
Or can we close a webpage in any other way?

waiting for your valid reply...
thanks in advance

Sebastian

This is being asked for security reasons. You can avoid this by workarounds.
Before calling close(), get the window in a variable and close. HTH.

Thanks,
Ziyad Mohammad[http://www.dotnetsoldier.blogspot.com/]

Thanks for your reply. I got the answer by placing
window.opener=self;
just before the close command.

once again Thanks Smile | :)

Sebastian

Assign some value to window.opener. That way IE would get to think that the window is created by you and it would obey the master without any demur.

hi,
in my application i have given facility to upload a zip file on server.
but when uploading file it's giving me error that "d://temp/temp1.zip" access denied.

and i am saving file in outside the application folder.

Why this error is coming ? any idea ?

Thanks,
Sun Rays

If you are accessing this zip file from your application, check that application (ASP.NET, IIS in case of Web application) as enough rights to access it

Sincerely,
Elina

Life is great!!!
