Server.Transfer transfers page processing from one page directly to the next page without making a round-trip back to the client's browser. This provides a faster response with a little less overhead on the server. Server.Transfer does not update the clients url history list or current url. If u want to update ur url address it is better to use Response.Redirect();
eg.Response.Redirect("mainmenu.aspx"); Smile | :)

Hi Thanks for the reply.
But is there a way for my sitemap to get the correct node even if I use Server.Transfer? Below is the code I used to resolve SiteMap in Global.asax.

Function AppendQueryString(ByVal o As [Object], ByVal e As SiteMapResolveEventArgs) As SiteMapNode
If (Not (SiteMap.CurrentNode) Is Nothing) Then
Dim temp As SiteMapNode

temp = SiteMap.CurrentNode.Clone(True)

Dim u As Uri = New Uri(e.Context.Request.Url.ToString)

temp.Url = (temp.Url + u.Query)

If (Not (temp.ParentNode) Is Nothing) Then
temp.ParentNode.Url = (temp.ParentNode.Url + u.Query)
End If
Return temp
Else
Return Nothing
End If
End Function

Thanks in Advance

because Server.Transfer is transfer the server from one page to another and actuaaly it is to handle the server side control not the client side controls.
and change of url is just cilent area of web-application

better to use
Response.Redirect(http://localhost/WebApplication1/WebForm1.aspx");

I've come across this odd behavior, that I'm not quite sure what to make of it, or even how to determine the source of the problem.

Ok, I have one page.

3 different buttons on that page.

asp:Panel ID="PanelNew" runat="server" Width="97%" >

asp:button runat="server" text="MostRecent" OnCommand="SelectActiveView" CommandArgument="MostRecent" CommandName="Hide" />
asp:button runat="server" text="Most Recent 2" id="testbutton" />

/asp:Panel>

Then I had code in the page load that is:

<br />
<br />
        testbutton.Command += new CommandEventHandler(this.SelectActiveView);<br />
        testbutton.CommandArgument = "MostRecent";<br />
        testbutton.CommandName = "Hide";<br />
<br />
        Button TempButton = new Button();             <br />
        TempButton.Text = "Cancel";<br />
        TempButton.Command += new CommandEventHandler(this.SelectActiveView);<br />
        TempButton.CommandArgument = "MostRecent";<br />
        TempButton.CommandName = "Hide";<br />
        PanelNew.Controls.Add(TempButton);<br />

So, I have on that's declared in html, one that's declared in html then modified from code, then the last is complete code made, all three buttons end up having the same command arguements, but the one made from code behaves differently from the rest. The function they call, modifies some hiden value fields then calls a page load.

Ok, now this part, is hard to explain, so please stay with me.

If I go straight to that page from a link, all three buttons work, first try.

If I click on a button that does a post back on to the page, then I click on the tempbutton, the hidden field values are not updated, Then I click the same button a second time and it does update the hidden values like it was supposed to on the first click.

Well, I hope that made sense. If it didn't then post that and I'll see if i can post some source code to duplicate this behavior.

A couple of things come to mind:
+ Try to give the control an id when you statically declare on the web page or dynamically load the control in code.
+ Try to add the dynamic control in the Init phase in the control life cycle.
+ Just curious that why you try with 3 buttons that have the same command name and argument.

My problem in a nutshell is the programmatically created controls aren't working 100% of the time.

NOTE: Giving the Programmically made controls an id fixed the problem, and thank you minhpc_bk for the help.

However I made some sample code to demonstrate the problem, what's cause the problem, is still abit puzzling,

To replicate the problem:

When the page first loaded the hidden value is blank, then I click on ButtonR1 or R2 to make it red. So on and so on.

Now, if you start clicking on the buttons in the "Panel Created" panel, they don't work 100% of the time. You have to click the same button twice in a row for it to work.

Here is a simplified example of my problem.

Hi there,
Basically, the ASP.NET processes the postback event like Command based on the id of the control. When you dynamically create and add the control, the ASP.NET will generate the automatic id if you don't explicitly specify a value. And if the id of the control before and after it is clicked, the postback cannot be routed to the right control, and as a result of this the event handler does not execute. You can check this thing by doing a view source the web page. Here it's really odd that you call the Page_Load event handler again in the SetPanelColor as it leads to the fact that you recreate the dynamic control. Instead, you can seperate the code to set the backcolor of the panel in a method ,say SetPanelBackColor, then you can call it in both the Page_Load and SetPanelColor methods.

Just because you did not get an immediate answer to your question does not give you carte blanche to abuse the forum as you done in the thread above. [^]

In any case, abuse the forum and you will find that nobody will respond.

ALSO. The Code Project members visiting this forum answer questions out of the goodness of their heart. Code Project members are not employees of Code Project and are not duty bound to answer at all. If you read the rules of Code Project then you would know that !!!!

To show good faith I suggest you delete the thread as stated above.

elegant coding style - checkboxs

30-Jul-06 3:41

Hi,

I have a group of checkboxs in the beginning of each row of a table. Each row has other controls in it. When I get a set of values back from the database and one of the values is of course what checkbox sould be checked. I am wondering how u guys would code the rest of the fields in the row to be databound. Now i'm not asking how u databind to a control, I know how to do this. I'm asking would u put your code in a select statement on checkbox value and then put each row of controls names in between a case? or maybe a set of ifs ... I don't want to do that personnally. So i'm asking if anybody has come up with a better solution since i'm sure this is common situation in programming.

Thanks,
JamJ

hi,
when using placeholder we can inject a contol to a page wich the control is instantiated.pretend that a user has built a page wich is asp.net page (with asp.net controls and maybe asp scripts)but it is not saved as asp.net page or usercontrol on the server so it is in the sql and every time the user requests his page we want to load his page and render all of the asp.net controls in the page,like what it is in the cms applications,i want to know how can i do this ?

Guffa29-Jul-06 23:03

You can use the Page.ParseControl method to parse a string into a control, then add it to a placeholder.

why? Change your design.

you might as well save it as an html page and just display it
