Hello,
I recently found a popup calendar control here: http://www.ezineasp.net/post/ASP-Net-PopUp-Calendar-Control.aspx[^] that works great! But the trouble I am running into is that, if I try to apply some validation; e.g. date rangevalidator, to it, nothing happens. I figured out that after the value was being set in the text field that the 'OnTextChanged' event is never being fired, probably because focus is not be given to the textbox. To get the validation to work I had to actually click into the field and press enter, this triggered the desired validation to take place. What I want to happen is for this automatically trigger the validation of course. I set the following fieds CausesValidation="true" AutoPostBack="true" but have had no success. Does anyone have any clues as to what I should do?

You don't seem to understand how asp.net controls works in general, I don't recommend using every control in the ASP.Net object library because most of them are useless.
I use the Jquery Calandar instead, and use 2 of them for a date range.

onChange is a JavaScript event that fires in the DOM, but the text literally has to change in order to fire, and will fire when you place the value in it, and when the date changes, so most people don't use that event. You trust the value is correct, and use onBlur to double check it after the change is made. If it's wrong, you send them back to the calendar.

Member 9952350 wrote: CausesValidation="true" AutoPostBack="true"
I believe this just applies to buttons, or the input element type button or an image button. When you set CauseValidation = true, the server will add a line of javascript that will fire the validator control when that button is clicked with a mouse.
I've never used it in a textbox control, but there seems to be support for it. The need to postback a page to check the value of a textbox is stupid. You only want to post a page back once.
The rule of thumb is to validate before submission. You can do it all at once, or on every blur event in the DOM.

[Final Thoughts]
I think the asp.net validators are a joke, and are provided for some demonic reason that I can't figure out. They are unreliable, and I got many phone call complaints about them. So I dumped them and went straight to the DOM for validation. I'm upset because I wasted years using them for no practical purpose or reason, only having to rewrite them all over again.

Thank you for the insight and yes you sound very angry lol. But I appreciate the perspective, as to, feel like alot the ASP controls not very useful. Anytime you get ready to do any little that is not excatly standard functionality, you basically seem to have to rewrite the entire control/tool to get the job done.

It comes with experience, as you get better with the UI, you'll find industry standards more useful. But it wasn't me that complained, it was customer feedback and failed checkouts.
But asp.net does rock with in code behind, you can do almost anything with it.
[edit]
It's just my opinion of asp.net controls in general, in which customer complaints were high.

Easier said than done. You really should just drop one down on your webform and play around with it first, and work on the CSS you need to style it, then load it up with your data, and write code for expand and collapse.
The treeview is pretty complicated, and doesn't really work very well across all browsers, so it requires some browser detection and some tweaking for each node and child nodes.
So for IE, the text on the nodes read clear, but on firefox, the text is very fine, but perhaps it depends on your monitor or video card.
As for right clicks, I tried that and decided thar the work required to enable right clicks outweighed the use of them. Then you have to determine which node or child node was selected, and what the object type is to take action to.
You really need to write your own code, or google for sample code instead of asking us to google for you.
I use it to show files in a folder by file type, and place the appropriate icon next to the file type. So I do a folder read, and create nodes in code without binding.

Hi,
Sorry for my late reply. I am able to get all other control id's in the iframe, except the ajax controls. That's the main problem here.

did you try the $find statement to locate the modalPopupControl?
$find("ModalPopupExtender1").show()
|
|
|
|
|
Finally i got a workaround to solve the issue.
I used $Find("ModalPopupExtender1") inside the page in iframe but returned null.
So i called a javacscript function located in the parent page from the child page.
In the javascript function, i closed the modal pop up window.
Thanks for your time and help.
Regards

Your Welcome.
I've use the find to close the popup, but not in an iframe, but it's in the right direction.

Here, i am using the following code in the iframe aspx page
if(window.parent.document.getElementById("AlertNotesExt"))
{
var iframe = parent.document.getElementById("AlertNotesExt");
iframe.hide();
}
}
AlertNotesExt is the id of ajax modal pop up extender. But in that place, if i give any other asp.net cpntrol id like button etc., i am getting the id.
Regards

Right-click the bin folder of your web site in solution explorer, click "Add reference" - click the tab for browse, find your DLL, open it, done.
Alternatively, you can put the code for your class files in your App_Code directory, and it will be compiled as part of the web site. If the helper class is only for the one site, that is probably a better way to do it. If it's a shared data layer, then you're doing the right thing with a DLL as a separate project.
There is a third way to add it as well... add the project for the DLL to your web site solution - so you have two projects in the solution, the site, and the class library. Then, create a "project reference" using the above procedure to add a reference, but use the project tab instead of browsing to the DLL itself. The project output (DLL) will automatically be referenced by your site.
In your code, you may also need to add using statements that point to your namespace.

Frame is nothing but a window. How about body's onBeforeUnload or onUnload events for the documents that are loaded within that frame in discussion?
