asp.net - Problem finding a control within a FormView from code-behind -

-

The code behind here ... I am trying to regain this control so that I am in the drop down list Add item (I am retrieving the code-back to add to the drop-down list in the role group) 

  Protected Sub Page_Load (ByVal, as in this System.Object, ByVal e System. EventArgs handles MyBase .load dim DDRoleGroups DropDownList DDRoleGroups = FormView1.FindControl ("DDRoleGroup") as End Sub   
 Here is the FormView:  (I Es took most so it's easier to read)   
  & lt; ASP: FormView ID = "FormView1" runat = "server" DataKeyNames = "id" DataSourceID = "ObjectDataSource_Vendors" DefaultMode = "Insert" BorderColor = "DarkGray" BorderStyle = "solid" Borderwyuth = "1 px" cellpadding = "4" visible = "Wrong" & gt; & Lt; EditItemTemplate & gt; & Lt; / EditItemTemplate & gt; & Lt; InsertItemTemplate & gt; & Lt; Label class = "form_label" & gt; Role Group: & lt; / Labels & gt; & Lt; Br / & gt; & Lt; ASP: DropDownList ID = "DDRoleGroup" runat = "server" width = "175px" EnableViewState = "false" & gt; & Lt; / ASP: DropDownList & gt; & Lt; / InsertItemTemplate & gt; & Lt; / ASP: FormView & gt;  
 
 Is this probably the fact that this Page_Load is in sub and control is not loaded acctually yet? 
 
 Thanks, Matt 
 What to do with

Your do dropdown only exists in insert mode trying to implement ModeChanged event FormView control is retrieved, then CurrentMode insert ==: 

  protected void FormView1_ModeChanged (object sender, EventArgs e ) {if (FormView1.CurrentMode == FormViewMode.Insert) {dropdown list DDRoleGroups = FormView1.FindControl ( "DDRoleGroup"); // fill dropdown}}

You can not handle it in page_load, because the form is not currently running in the Insert mode.

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

Visual Studio 2005: How to speed up builds when a VSMDI is open? -

-
Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

booting ubuntu from usb using virtualbox -

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never
