In my page I have a read-only TextBox that contains a rather large amount of text. I noticed that on postback this text is sent back to the server and validated, even though the client can never modify it. This seems silly; is there a way to disable this behavior?

I am having problems selecting the text within a TextBox in an UpdatePanel in IE 8. Consider a very simple page that contains a single UpdatePanel. Within that UpdatePanel there are two Web controls:
A DropDownList with three statically-defined list items, whose AutoPostBack property is set to True, and
A TextBox Web control
The DropDownList has a server-side event handler for its SelectedIndexChanged event, and in that event handler there's two lines of code:

i want to get the contents of a textbox and set them to a asp label for output, we can cause a postback to if that makes it easier, so far i did this and it comes up trumps
View 11 RepliesI have an ASP.NET checkbox, and I want to run some javascript before it posts back.
Something like:
<asp:CheckBox ID="chkSelected" runat="server" AutoPostBack="True" OnCheckedChanged="chkSelected_CheckedChanged" />
but I want to run a JS confirm dialog when the user click it, and if they were UNCHECKING it, I'd like to ask them if they're sure, and if so, postback and run my serverside code. If they say No, don't postback at all.
I want to allow users to click only once on button. In fact, the button is a user control:
[Code]....
That button control gives us access to OnClientClick property of lbButton. This button is used on other user control:
[Code]....
As you can see - i disable button on client-side and then return true (to do a postback). That's for only sample purposes. This code will disable my button but there will be no postback. If leave only "return true;" inside onclientclick script then i'll have my postback. The conclusion is - i can't do a postback if i disable button. The question is what's the reason of such behaviour and can i do any trick to over overcome this issue. I figured out i can hide button and still perform postback. But why it can't be disabled? There was already a thread on similar topic : [URL] but answers weren't satysfying. User Participant gave his solution there but i'm not fully understand his idea. Could someone explain to me why it can't be done my way and if it can be done by any other method?

View 3 RepliesI have a survey, where you have to click through several pages with questions. I use a "Next" and a "Previous" button for doing this. I use a session for keeping tabs on my position. However, this is a problem.
I use the button_click event to increment the page counter, but since this fires after the page_load event, nothing happens on the first click, and for every click thereafter everything is one page behind because the questions are rendered before the counter is incremented.
Is there any way to solve this without using the query-string?
Comment response 10:15:
My understanding is that the following happens:
The first page loads and the counter is not set. The counter is set to 1. The first page is displayed. The user clicks the "Next" button, firing a postback. The page loads, displaying the same set of questions, because the counter is still on 1. The buttons Click-event is run, incrementing the counter. However, the page is still displaying the old questions.
After this everything is one page behind because the questions are rendered before the click-event is fired, incrementing the page counter.
I have a GridView control which contains a custom <pagertemplate> with a <asp:PlaceHolder runat="server" ID="plcPages"> control. The .aspx.cs file contains the following code:
protected void Page_Load(object sender, EventArgs e) {
... {Other Code} ...
GridViewRow pagerRow = GridView1.BottomPagerRow;
PlaceHolder PagePlc = (PlaceHolder)pagerRow.Cells[0].FindControl("plcPages");
Button btnPage;
int iPageNum;
for (int i = 0; i < GridView1.PageCount; i++) { iPageNum = i + 1;
btnPage = new Button(); btnPage.ID = "btnPage" + iPageNum.ToString();
btnPage.CommandName = "Page"; btnPage.CommandArgument = iPageNum.ToString();
btnPage.Text = " " + iPageNum.ToString() + " ";
PagePlc.Controls.Add(btnPage); } }
Everything works fine the first time the page is displayed. But, when I click any pager button, including the Next and Prev command buttons that are not part of the PlaceHolder, the contents of the PlaceHolder are never re-displayed. I know from searching other posts that the PlaceHolder contents are lost during the trip to the server, but I am already recreating them every time the page is loaded. They are just never being shown again. I've spent the last two days playing with ViewState And every other combination.
I have gridview. In my griview, i have Fileupload template field.

I have 2 textboxes and a submit button inside a .net composite server control. I tried to only postback when submit button is clicked. I set autopostback = false for both textboxes. But either one still trigger submit button's onclick event by hitting "Enter" inside textbox. How can I stop postback by enter key?

View 15 RepliesI have a TextBox using the AjaxControlToolkit's MaskedEditExtender, the extender is using the Date mask (99/99/9999). We had modified the toolkit code to support 2-digit year (as seen in this post) which works just fine when the date TextBox initially has no value. But when the date TextBox has an existing date such as 10/04/2010, if I type in say 100409, it becomes 10/04/0910, in other words it doesn't replace the existing year but simply replace the first 2 digits of the year. If I first hightlight the entire field then type then it works. My question is is there a way to hightlight the entire date value of the TextBox upon entering the field?
I tried using javascript code textbox.focus() and .selet() but it doesn't highlight anything, it just places the cursor at the beginning of the textbox.
I'm trying to write the contents of a TextBox to a file but can't seem to find the right method. Whats wrong with this code?
Dim FileName
As
HtmlGenericControl
= TryCast(DetailsView1.FindControl("TextBox2"),
HtmlGenericControl)
Dim newFilePath
As
String = Server.MapPath("/myXML/"
+ FileName.InnerHtml)
If I replace FileName.InnerHtml with "myXML.xml" it works.

View 4 RepliesAfter witnessing some strange behvior I'm confused about ViewState again :/
My understanding was a textbox needed to have "EnableViewState" set to true otherwise when the you postback the fields contents would disappear.
That's not happening, I created a textbox and button and a label.
The button was set to copy contents of text box into the label when I pressed it.
I did and the text was populated into the label and remained in the textbox?
This was inside an UpdatePanel and the page itself has a MasterPage, so that might have something to do with it, but I have about 50 textboxes on this page all with viewstate=true on, so I would really like to know what controls need to have enableViewstate=true in order o function properly.
I'd like my users to upload MS Word documents -- instead of typing the information in a TextBox. Even though I use tinyMCE -- like in this site, most users still seem to prefer the highly sophisticated Word environment.
My goal is to allow them to upload their Word documents which I then convert to HTML and place it in a tinyMCE enabled TextBox control. Has anyone implemented this? If so,

I have a code where I fill some random text into a textBox. In this example there is more content than the textBox can show so the vertical scrollbar is shown in the textBox.
I wonder if there is a way to adjust the height of the textBox instead automatically so all contents can be seen instead of seeing the scrollbars ?

I also use a text box and session variables to send parameters to a stored procedure and return a single row result in a form view.
