Using A CustomValidator Control In The InsertTemplate Of A ListView?

Mar 6, 2010

VWD 2008 Express. Visual Basic.

I have placed a customvalidator in my listview control in the InsertItemTemplate. I want to make a check before the insert is done and set the validator to false if the test fails. I placed the code to check this in a click event routine that fires when the "Insert" button is clicked. When the code tries do a FindControl for any controls in the ListView, I get an error saying, "Object reference not set to an instance of an object."

Here is the code:

CustomValidator Control In Visual Basic

Mar 12, 2010

VWD 2008 Express. Visual Basic.I have a customvalidator on my page and a corresponding OnServerValidate routine tied to this control in my VB code behind. I also have a "Save" button that is defined as "CausesValidation=True." I placed a breakpoint in my OnServerValidate code for the customvalidator and a breakpoint in my OnClick routine for the Save button. What I expect to happen is that when the "Save" button is pressed, all the validation is checked before ever entering the OnClick code for the Save button. If any of the validators are false, then I expect that the Save button OnClick code will not run.

Web Forms :: ServerValidator Event Of CustomValidator Fires Unexpectedly When Control CausesValidate="False?

Mar 19, 2010

I have a fairly complex master/content page that has several GridViews - each one in its own UpdatePanel. I also have four CustomValidators on the page, each one assigned to a different
ValidationGroup. Two of the CustomValidators are buried inside a HeaderTemplates of a GridView (inside a distinct UpdatePanel). In the EmptyDataTemplate, HeaderTemplate and FooterTemplate of each GridView I have ImageButtons that postback to the server to perform some operation. All the ImageButtons take this form:


When I click on the ImageButtons in one of my GridView's the ImageButtons cause the ServerValidate event of two CustomValidators to fire. The server-side OnClick event of the ImageButton never fires. I have verified that the ImageButton(s) have CausesValidation="False" - what could be causing the validators to fire?

Forms Data Controls :: How To Push Down Outer ListView From Nested ListView Control

Mar 13, 2011

I have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?

Web Forms :: How To Reference CustomValidator

Sep 2, 2010

I have two CustomValidators, both of which function in the same way (call a query and check if a particular value is available in the DB), the only difference is the query itself.

Rather than writing the same function definition in the code-behind, I would like to find a way to execute a particular query depending on which CustomValidator called the function (I guess using the CustomValidator's ID) so if I have the follwing:


How can I check in the code behind , which validator called the function "Check"??

CustomValidator On Multiple Controls?

Oct 6, 2010

I am working with a page that has a series of checkboxes that at least one box must be checked.

The validator fires when I click the submit button and if no checkboxes are checked indicates the validation has failed. However If I check one of the checkboxes the validation message does not go away until I click the submit button again.

If I was using this on a control in which I had specified the ControlToValidate and I fixed the validation issue the error message goes away immediately.

However in this case I am not setting the ControlToValidate due to the neeed to validate serveral independent controls.

So my question is can I cause a re-validation of the custom validator? For instance I would like to add on each checkbox a onclick="revalidate()" that would then force the validation to happen again.

Here is some sample code that I wrote to demonstrate the scenario.

<script type="text/javascript">
<script type="text/javascript" src=""></script>
function IsOneCheckboxChecked(sender, args) {
if (!$('[id$=checkBox1]').attr('checked') &&
