Re: Overriding __doPostBack in ListView

I'm planning to avoid postbacks and ViewState altogether, and just call webmethods from the client. I know I can easily do this without using a ListView at all, but I'd like to try it with the ListView so that I can keep using the DataPager (which only works with ListView).

So my plan is to just use the ListView like a Repeater to build my table, override the __doPostBack so that it does what I want (i.e. call a webmethod rather than do a postback), and hopefully still be able to use the DataPager.

I guess I'm just asking whether anyone else has tried that approach, or can suggest a better one, before I commit loads of time to it.

I'm not sure what you gain by getting rid of postbacks/viewstates. If you want to mimic the look and feel, then design your ListView then see the client side generated code. I don't have .net3.5 (which ListView is supported), but, I think, it will get rendered as table. Get the table layout and structure and use straight table with some css to achieve similar look and feeling.

If you want to override postback, then prepare to write some client side code to supplement. I know you mentioned you want to call webservices. Do you need to support sorting, pagination ....

In any case see here[^] and here[^] for one way of overriding postback function

May I help you?

Thanks Yusuf. The ListView is template-based, so will generate whatever you put in the template, but yes, that's usually tables.

Thinking about it, I guess the only thing I gain by keeping the ListView is easy pagination (the DataPager control). Maybe the easiest thing will be to just abandon ListView and write my own pager.

Thanks again.

Checkboxes for Parent and Child in Treeview

meeram39511-May-09 0:51

The treeview control has an attribute called ShowCheckBoxes which contains the values as"All,Leaf, Parent, Root and None". Because of this, I cannot add the checkboxes both for Parent and Child.

Is there anyway that I can add the checkboxes both for parent and child? Please help.

Hi,

You have to write code like this,

Protected Sub TvwPages_SelectedNodeChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TvwPages.SelectedNodeChanged
            If TvwPages.SelectedNode.Text = "Screens" Then
                  If TvwPages.Nodes.Count > 1 Then
                        TvwPages.Nodes(1).Collapse() 'Collapse Reports
                  End If
                  TvwPages.Nodes(0).Expand() 'Expand Screens
            ElseIf TvwPages.SelectedNode.Text = "Reports" Then
                  If TvwPages.Nodes.Count > 1 Then
                        TvwPages.Nodes(0).Collapse() 'Collapse Screens
                  End If
                  TvwPages.Nodes(1).Expand() 'Expand Reports
            End If
End Sub

If you have more than one Tree View item,
Use this line ,( PUT in a For Loop) till List Count

                     TvwPages.Nodes(i).Collapse()

Hi,

Try Using this....

Protected Sub TvwPages_TreeNodeExpanded(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.TreeNodeEventArgs) Handles TvwPages.TreeNodeExpanded
            If e.Node.Text = "Screens" And TvwPages.Nodes.Count > 1 Then
                  TvwPages.Nodes(1).Collapse()
            End If
            If e.Node.Text = "Reports" And TvwPages.Nodes.Count > 1 Then
                  TvwPages.Nodes(0).Collapse()
            End If
End Sub

and..one thing...never say URGENT. It is completely irrelevent to others.

when user logged in i set its LoginBit and didnt allow same user to log in again but if user closes without signing out and he returns then how can i found that it is the same user who was actually using the session. he must not receive error that user is already signed in

Try any one,

1 - Handle session_end and rest the DB flag. session_end fires even user closes the browser(not immediately).
1 - Handle the window closing event using JS, do AJAX call to reset the DB flag.
2 - Run a DB job which will check the records frequently and resets the flag.

Poor way of keeping dates. Why don't you make the column type as Date?
