AutoPostback in Repeater in UpdatePanel is refreshing the page

Here's quite a weird problem:I've got a TextBox with AutoPostBack="true" and OnTextChanged property set.The textbox is located inside a Repeater, which in turn is located inside an UpdatePanel.Problem is - whenever the TextBox postsback, the whole page gets reloaded, instead of the UpdatePanel only.Here's how the thing looks:<asp:UpdatePanel runat="server"> <ContentTemplate> <asp:Repeater ID="itemsRepeater" runat="server"> <HeaderTemplate> <ul class="lstProducts"> </HeaderTemplate> <ItemTemplate> <li> <asp:TextBox AutoPostBack="true" OnTextChanged="whatever_Click" runat="server" /> </li> </ItemTemplate> <FooterTemplate> </ul> </FooterTemplate> </asp:Repeater> </div> </ContentTemplate> </asp:UpdatePanel> Interesting thing is, if I take the TextBox out of the repeater, it refreshes only the UpdatePanel.So is if I put a Button inside the repeater - only the UpdatePanel gets refreshed.But whenver I place an AutoPostBack-ing control inside the Repeater, the whole page gets refreshed.Any help would be welcomed,Thanks<asp:UpdatePanel runat="server">             &

Stop ImageButton from refreshing page


I have an ImageButton programmed to open up a new window with a small onclientclick javascript routine.  But, when the ImageButton is clicked, the page containing the button reloads too, causing both a delay and loss of position on the page.  I don't need the page to reload, just the new window to open.  How do I prevent this?

Changing the graphics on the home page of a SharePoint site

When you create a site in Microsoft Windows SharePoint Services by using the default Team Site template, the home page includes two default graphics. A Windows SharePoint Services graphic appears in the body of the page, and a picture of a house in a circle appears near the site title. You can change these graphics to customize your site. Changing the smaller graphic requires a Windows SharePoint Services compatible Web page editor

I have 2 web pages. First page has a textbox and a button control.

when I enter test and click on the button , system goes to the second page. And in the second page I want to access the Textbox in the first page. When I try to do this I get the following error.

"Object reference not set to an instance of an object. Following is my code :

Dim txt As New TextBox

' Find the server name on the previous page
txt = CType(Page.PreviousPage.FindControl("TextBox2"), TextBox)
If Not IsNothing(txt) Then
Response.Write("[Name Not available]")
End If

I know I could do this with session, but I want to use the Page.PreviousPage.FindControl. Any help is greatly appreciated

Unique content within master page based on conditions met


 Hi all-

I would like to present users with unique content based on certain conditions being met as they land on the home page (default.aspx).  The condition logic will be in the VB code behind Page Load event. The content will go in a content placeholder as specificed from the master page. 

However, the content change wouldn't be something small (ie making a panel or label visible or not) but rather it will be different HTML,  Divs and databound gridview content.  The HTML content will be stored in the database.

Can someone point me in the right direction for best practices on how to accomplish this?


Launch CMD File From ASPX Page


My organization uses a CMD file to install updated files for a major enterprise application. Currently, we send out an email to users with a link to the file and instructions to run it, BUT inevitably users don't update their machines until their in field and try to start the app.


We're now liking the idea of using an ASPX page to prompt the users to run the updates and to capture the fact that the updates have been run. I realize that we can't capture the success or failure of the update. But we'd like to capture the user accessed the page.


Is it possible to embed into the markup for the page a link to the file on the local intranet that the users can click on to run the file?

The user accessing the page would capture that they did just that. We'd deal with wether or not the update was actually installed or if it failed later with them directly.
