Web Forms :: Does "requiredfieldvalidator" Work For Image Fields
Jul 24, 2010
As you can see below, I'm trying to use "requiredfieldvalidator" to require an image---but I'm getting an error message (saying the Image field can't be validated.) Will requiredfieldvalidator not work with images (only textboxes)? Any suggestions for resolving this? Is the only solution to require the image programmatically in the code behind?
<asp:Image ID="Image" runat="server" AlternateText = "No image uploaded yet" ImageUrl ='<%# Eval("UserId","Image.aspx?UserId={0}") %>' Width="50px" Height="75px"/>
<asp:requiredfieldvalidator ID="ImageRequired" runat="server" ControlToValidate="Image" ErrorMessage="All fields are required. Please try again." display="static" ToolTip="All fields are required. Please try again." SetFocusOnError="true" CssClass="validate"></asp:requiredfieldvalidator>

We would like to display an image of a checkmark if the input was valid or an image of a stop sign and text if the input was not valid.I believe I need to do override the EvaluateIsValid method. I have never extended a control before and was hoping someone could point me in the correct direction.

I am uploading an image using the FileUpload control. After I have uploaded the Image to the server and the image is saved there, I am trying to show this image in an ImageBox like in the code.But the image is not shown in the Imagebox. I had this problem for some time but now wonder why the Image isnīt showing in the ImageBox. I have also tried to use the Page_Load event to track the SessionVariable to show the Image but this does not work ?(The file gets uploaded and saved to the specified path anyway, that part works)

I have a small function that is in a STA thread. It's purpose is to copy the selected image in word document to clipboard and then save it to a location on the hard drive. Here is the code that works fine on XP and Windows server 2003.
protected static void CopyInlineShapeFromClipbord()
{
string imageFileName = string.Empty;
_oWordApplication.Selection.Copy();
Computer computer = new Computer();
if (computer.Clipboard.GetDataObject() != null)
{
System.Windows.Forms.IDataObject data = computer.Clipboard.GetDataObject();
if (data.GetDataPresent(DataFormats.Bitmap))
{
Image image = (System.Drawing.Image)data.GetData(
DataFormats.Bitmap, true);
imageFileName = _imageUrl + ".gif";
image.Save(imageFileName, ImageFormat.Gif);
_imageUrl = imageFileName;
}
}
}
It does not work on Windows server 2008 on IIS 7.0 Is there some known WP Identity issues or any other kind of security issues in cross process memory sharing?

I have a sql data souce that returns several columns of data, and they are displayed in a DetailsView on a pretty simple vb.net page. I'm stuggling with one field though for the details view.
It's a template field, and if ClientType=1 (this value is determined else where on the page), then the label in the template field should have Text='<%# Bind("ClientName") %>', but if the ClientType = 0, then the label in the template field should have Text='<%# Bind("ClientTemporaryName") %>'
How do I tell the details view to set the text for ClientName to one or the other?

I am using TempleteFields for all columns in my GridView. In that columns I am using only some fields for customization but not all.
Is there any performance issue with Databound Fields vs Templete Fields in a GridView...?
Do I need to replace the remaining columns with Databound Columns instead of TempletField columns...?

I have a GridView, and I want Column1 to be equal to datatable data (filled by a SqlDataAdapter). Then I have two other fields by the SqlDataAdapter (first name, last name), and I want to have those two fields combined to form Column2. I have a TemplateField for my GridView that combines the first name and last name with Eval()'s, but the GridView places this combined field TemplateField and puts it as the first column.
How can I do this so that TemplateField can go in between fields that are databound?

I create a new website in VS 2010 (VB .Net). I add a table, within it i add a textbox, a button and a RequiedFieldValidator. I set the RFV ControlTValidate property to the textbox. When i move(click or tab) away from the textbox, the RFV doesnt kick in the error message that i have set.
The RFV code is
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ControlToValidate="txtEnterName" ErrorMessage="RequiredFieldValidator"
InitialValue="0" ForeColor="#FF3300"></asp:RequiredFieldValidator>
Texbox
<asp:TextBox ID="txtEnterName" runat="server" Width="221px"></asp:TextBox>

I am using ckeditor as my Rich Text Editor (RTE). This is an html element control and not an ASP control. I would like to use the RequiredFieldValidator (RFV) control to make this field required.
I cannot find any documentation stating that the RFV can be used like this. Can anybody tell me if this is possible?
Here's an example - notice that there is an html textarea element - how do I use RFV on this?
