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?
i have webForm which have aspxMenu as toolbar.my problem is that when user click on aspxMenuItem, my requiredFieldValidator doesn't work, but when i use simple button instead of aspxMenu, it works!
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 have a problem about image control. I am using VS2005 in Vista and suddenly uploading and retrieving image to a image control doest not work. I am working with this in Windows XP and all goes fine. After transfering it to vista, I can't upload and retrieve an image stored in the File System. My codes are all the same.

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 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.

Here's an example - notice that there is an html textarea element - how do I use RFV on this?
