Accessing a textbox value on the parent form

[dpdoug]

I have a web form (let's call it MainForm) with a textbox to get a certain date from the user. I need to store this date somehow server-side for later use. It was working fine while I was having the user click on the button on Mainform, but because of the client's specifications, I can't use a button to store this value, so I had to take it off. Now I'm trying to figure a way to get that value.

I have an iFrame (let's call it MyFrame) that has a web form in it that posts values to the database. At the time it posts, I need to be able to get the Date from the textbox on MainForm to post with the rest of the data.

I tried triggering a submit on the onblur event of the textbox to try to save the value to a variable on the server, but that didn't work. I tried accessing the textbox's value using the parent property, that didn't work either.

dp: I have successfully pulled text values from the Main page into an IFrame aspx page by referencing accordingly:

iftext.Text = '<%=txtMyText.Text%>'

See if you have any luck with this (you might also try this using a declared string variable).

My problem is getting the value into the variable. Since an asp:textbox has only 2 events, and neither of them will trigger getting the value into some kind of variable on the server, I have to grab it some way on the client side.

If I could use the onload event of the page loading into the iframe to grab the values from the parent page and put them into hidden text boxes, that would work for me.

This is conceptually what I need:

MyIframe.MyIframeTextbox.Value = ParentForm.ParentFormHiddenTextbox.value

I could even use the onclick event to grab the value from the iframe. I just can'tuse it on the parent form.

David - just a thought - you could trigger javascript OnLoad and perhaps use something on the order of

.....=" + document.forms["Form1"].elements["txtMyText"].value....

..just a thought.

The problem is that this doesn't grab the value from the parent form. The javascript OnLoad event would have to be triggered in the web form in the iframe.

David,

I have an iFrame (let's call it MyFrame) that has a web form in it that posts values to the database

How are you posting values from within the form in the iFrame?

David --

I have a main form aspx page, with an IFRAME embedded in it. When I post back the IFRAME aspx page, it can obtain a value from the parent form using '<%=strVar%>' in the IFRAME aspx page - that is what I was making reference to.

If you are posting back your IFRAME, MyFrame, I don't know why this doesnt work.

In my sitation I have a button on the IFRAME aspx page, and when I click on it to post it back, it then gets the parent form value using the above technique.

There is a web form in the iFrame (MyFrame).

I'm pulling data from the database from that web form that the user would select to put in the order when he clicks the button 'Add to Cart'. The thing is that there has to be a begin date and a return date to go with each item in the order that could possibly be different for each item.

Since I can't use a button to cause a postback to store the value on the server, I have to get the value from the client side.

The problem is getting the date values in the parent webform from the web form inside the iFrame to post it together with the rest of the values to the database.

DP - ok, I see what you're up to. Have to run this evening but what comes to mind is the document.getElementById technique.

I have been to one javascript (IFRAME) site in the past, had dozens of examples of exchanging params between the parent form and the IFRAME but can't locate the URL at the moment. I'll continue looking for it.

DP - one other note; I have had a lot of success over at the Java forum getting questions like this answered - and since its primarily client side you might post there; you probably already know this but those guys over there are pretty rambuncious.
