Hi.
I have a problem with selecting a control from codebehind.
This is my scenario:
1. i get a string from a webservice (session): string boxstring = "<input type="text" id="MainContent_TextBoxStopRoadName01" name="ctl00$MainContent$TextBoxStopRoadName01">";
2. i insert this string to a <div id="boxcontainer"> from codebehind like this: boxcontainer.InnerHtml=boxstring;
3. Page loads
4. User types text in the box, and clicks a button to submit it
5. How do i find this textfield from codebehind from its id? I would like to get the field as an TextBox control, but the text value is the most important.
I´ve tried several things, like Findcontrol("id") and Findcontrol("id").Findcontrol("id") and so on. But it doesnt work.
Another thing does work though, if instead of a string, I create the textfield as an TextBox control, and then insert it: BoxContainer.Controls.Add(TextBox); - then it works! But it is not a possible solution in my situation. I only have the textbox (among many other elements) in a string.
Really hope you can help!
Thanks

A page on the server is a transient object recreated whenever the browser requests the page. That's true for postbacks and callbacks too

I can't see any way of getting the control because it isn't a part of the pages controls but you should be able to get the value from the Request.Form collection after postback.

This really doesn't make sense to me. What is the purpose of this webservice? The html is useless, it doesn't have any context.
Since the control is being added to the innerHtml of the div at runtime it is not available during postback; it isn't part of the page's control collection.
You could accomplish what you are asking by using a Panel in place of the div, or adding the runat=sever attribute to the div you have
TextBox txt = new TextBox();
div.Controls.Add(txt);
Since it is being added dynamically you must recreate the control during postback but then you could access it's value.

Hi,
I am working on an application where I have to Drag n Drop selected item from DropDownList, I can successfully drag n drop items from selected list but I have a issue with mouseup event.
The problem is that when I leave the dragged object mouseup event of that object fires, now what I want to do is to fire the event of the control where I am dropping item.
One more thing, controls where I am dropping items are not fixed, they vary. Now I want to get the Id of the control where the element is dropped.
Thanks in advance.

To get the id of the item being dragged you could try storing it's id on the mouse down event, and then using it on the mouse up. To get the id of the control the item is being placed into, try using a hover event to set an id and then use that.

Are there any exceptions? Showing what you have done may help us to point out problems/solutions.

What is the meaning of "Open" file?
You want to open it reader or you want to execute file?
(suppose i have a word document and you want to open it with Microsoft Word or in memory)

If it is a ASPNET based solution (a website), you will need proper permissions to access temp folder. Check the app pool for your web site and identity/logon-user under which app pool is running. Make sure the identity has rights to access temp folder and files under that folder.

Hi Guys,
I have an adv banner , I want to calculate Number of user who click on banner.
|
|
|
|
|
OK, but do you have a question?

Store a count somewhere, increment by one each time it is clicked.
Where is your problem?
|
|
|
|
|
Are you trying to track the number of times the banner is clicked, or the number of individual users who've clicked on the banner? The two aren't necessarily the same.
|
|
|
|
|
Agreed..., but that is more or less just a filtering mechanism layered on the same click counter, isn't it? (I haven't had to do something like this in a very long time)
Now he has to go and re-read his homework for the weekend...
I wasn't, now I am, then I won't be anymore.

Indeed it is - but I like to help them to realise that they should think the problem through some more.

the number of times the banner is clicked.

Store the number somewhere and increment when clicked. Again, what difficutlties are you having?

A simple table in a database and an incrementing update statement will do nicely then.
