c# - Can I programmatically add a linkbutton to gridview? -

-

I am looking for some similar questions without any luck. What I want to do is a gridview that shows a link button for some items and shows a hyperlink for other items. I currently have this code: 

  public zero gv_RowDataBound (the object sender, GridViewRowEventArgs e) {if (e.Row.RowType == DataControlRowType.DataRow) {var Data = (FileDirectoryInfo) e .Row.DataItem; Var IMG = New System Web. UI. Html control HTML image (); If (data length == faucet) {img.Src = "/images/folder.jpg"; Var lnk = new link button (); Lnk.ID = "lnkFolder"; Lnk.Text = data.Name; Lnk.Command + = New CommandEventHandler (changeFolder_OnCommand); Lnk.CommandArgument = data.Name; E.Row.Cells [0] .Controls.Add (lnk); } And {var lnk = new hyperlink (); Lnk.Text = data.Name; Lnk.Target = "_blank"; Lnk.NavigateUrl = getLink (data.Name); E.Row.Cells [0] .Controls.Add (lnk); Img.Src = "/images/file.jpg"; } E. Ro Seals [0]. Control. AddAt (0, IMG); }}

Where the first cell is a TemplateField. At present, everything is displayed correctly, but linkbutton commands do not increase event handlers, and all controls disappear on postback.

Any thoughts?

After the

I think you should try to rebind the GridView > postback try needed. This will ensure that any dynamic controls were rebuilt and their event handler was re-connected.

Callback on IOW, gridview on callback.

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.

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...
