Now I want an set validation for mandatoryto the textbox TokenStartingNumberTextBox only If the user had entered the value in DateOfReceivingTextBox.
I have a custom validator:
<asp:CustomValidator ID="QuestionValidator" runat="server" ErrorMessage="Please select an option" ClientValidationFunction="QuestionValidator_ServerValidate" OnServerValidate="QuestionValidator_ServerValidate" ValidateEmptyText="true"></asp:CustomValidator>
I have a list of questions provided by a datalist, which I need to ensure a user selects an answer to each question. I then have my validation functions:
Protected Sub QuestionValidator_ServerValidate(ByVal source As Object, ByVal args As ServerValidateEventArgs)
Dim SelectedItem As Boolean = False
For Each c As Control In Page.Master.FindControl("form1").Controls
If TypeOf c Is RadioButton Then
[code]....
When I run the page, there is no validation and no error message. Please can you point out where I am going wrong, I'm suspicious it is at Page.Master.FindControl("form1").Controls.I have previously done such validation by looping through controls via form1.controls but this is unavailable as the page uses a form passed down via the master page.
This should be a simple problem to fix, as it uses the same way I fixed my last problem with FooControl (below).
Basically, I want to add a derived validator I made to this composite control. It works fine but on postback it just disappears in the markup, making me think it's lost its ViewState.
I am probably doing something wrong with instantiating it, but I've tried setting only the ControlToValidate, moving things around, and nothing works.
I've provided some surrounding code to see what's working and then what's not.
Private FooControl As IFooControl
Private Validator As MyValidator
Protected Overrides Sub CreateChildControls()

First of all I'm trying to create a validator that checks to see that if both players have entered a nickname. If they don't then it should automatically close the form but instead the application hangs. If the first player uses three tries then it "should" automatically close. Here it is:

erCount)

I finally finished all my labels and textbox codes for this button.But now I have to code it so that I will be able to click the button and it will calculate all the wrong and correct answers in the labels and then finally place the percentage score in the uiScorePercentagelabel. What I dont understand is how to calculate all the different labels as one and then show the percentage right in the appropriate label.
I have been using vb6 for a while, I am following a tutorial by MS to develop a basic application and a simple task cannot be completed for whatever reasons! The tutorial asks to drag the label object from the toolbox and drop in the tab control container. Then, go to the label size property and adjust the size to some different dimansion. Basic stuff, right? It won't let me do it! After I enter the new dimensions (which by the way are not large or very small), the label size (both width and height) resets back to its original dimensions! I have the vb.net sp1 installed.
