Web Forms :: Remove Last Line Of Multiline TextBox If Blank
Oct 18, 2013
In my asp web page, there is a multiline textbox. And upon a button click from the same page I need to delete the last row or line from the multiline textbox. How is that possible.
On my Asp.Net GridView I am binding a textbox to a field in SQL. Sometimes the content of the textbox is more than 1 line and I
need to show only the LAST line. How can I do that? Here is part of my code...notice that I use Rows=1 on purpose so that I am able to show only 1 line but I need it to scroll all the way down and have it show only the last line of the whole content:
How do I just get the first line of a multiline textbox? Either that or delete everything after "<br/>"? I tried something like this but it doesn't work:
When I trace the variable while debugging I notice that when using Internet Explorer 7, the text is parsed correctly from the text box and <br /> tags are inserted appropriately.
However when the page is ran in Firefox or Chrome, the line breaks are not converted.
I set my textbox1 to equal a responsetext string and when I click into the textbox and then click the end key there are spaces or blank space at the end. I need to get reid of them. I tried the following, but no luck:
1) Is it possible, in a multiline textbox, to automatically break to the next line after 100 characters? 2) If not, is it possible to parse the enter key as entered by the user to break the line in the code behind?
Some additional info:
The person requesting this does not think that the user should use a single line textbox limited to 100 characters and click an "Add Line" button to store that field in a table.
The person requesting this is of the belief that a DEC Alpha-based system that currently does this can be replicated on the web.
how to limit the number of characters per line in a multiline textbox? Any posibility to do this with javascript? I have the users enter a list of names and need to limit each. I hate to use another textbox to add each name. If so, I would then add them to a listbox instead so they could select and remove a name.

How to prevent the new line character at the beginning of the text entering in a multiline text box? Now, I already trimmed the white space at the beginning of the text. but i can't prevent the new line character that has to be occurred by entering the enter key on the most beginning of the text box.
I've updated a number of production sites from 3.5 to 4.0 and have found a really annoying problem where it will insert a blank space into Multi-Line text boxes
The tag is entered as.... <asp:TextBox ID="AdvDayNotesTB" runat="server" TextMode="MultiLine" CssClass="text" Width="99%"></asp:TextBox> <asp:TextBox ID="AdvDayNotesTB" runat="server" TextMode="MultiLine" CssClass="text" Width="99%" /> The HTML is rendered as... <TEXTAREA style="WIDTH: 99%" id="ctl00_C_FV1_AdvDayNotesTB" rows="1" cols="20">
When changing the textbox's text mode to multiline the textbox becomes resizable during runtime. I can't seem to find the property to disable this, does anyone know how I can resolve this issue?
