I have an asp.net textbox which stores a long string.
'99024','99050','99070','99143','99173','99191','99201','99202','99203','99204','99211','99212','99213','99214','99215','99217','99218','99219','99221','99222','99231','99232','99238','99239','99356','99357','99371','99374','99381','99382','99383','99384','99385','99386','99391','99392'

Open in new window

It is a long string without white space. It contains many short strongs that are around single quotes. What I want is to split it into many lines into the textbox. Each line only has one short string.

What I did is that
<asp:TextBox ID="TextBox1" runat="server"  TextMode="MultiLine" Text='<%# Bind("test") %>'>
                                    </asp:TextBox>

Open in new window

It doesn't work.
Thanks.

Hi,

Please add Wrap="true" and also add width and height if possible.
<asp:TextBox ID="TextBox1" runat="server"  Wrap="true" TextMode="MultiLine" Text='<%# Bind("test") %>'>

Thanks

I tried this from code-behind

On Page Load

this.TextBox1.Text = test.Replace(",", "\r\n");

If you want to go by data binding let me know.

The origian question is from a GridView. I want to display a long string. Wrap="true" is not working.
How to modify the code?
<asp:TemplateField HeaderText="ICD9" ItemStyle-Width="75px" SortExpression="ICD9">
                            <ItemTemplate>
                                <div style="width: 75px; overflow: hidden; white-space: nowrap; word-wrap: break-word;">
                                    <%# Eval("ICD9")%>
                                </div>
                            </ItemTemplate>
                            <EditItemTemplate>
                                <div style="width: 75px; overflow: hidden; white-space: nowrap; word-wrap: break-word;">
                                    <asp:TextBox ID="TextBox1" runat="server"  TextMode="MultiLine" Text='<%# Bind("ICD9") %>'>
                                    </asp:TextBox>
                                </div>
                            </EditItemTemplate>

then you can just insert newline in the string after specific number of charatcers in the source. like insert new line after each 100 or 50 charters in the source string,

It should work with Edit as well.  Can you take a print screen and post it here.
Also just in case, try setting Wrap="true"

 <asp:TemplateField HeaderText="ICD9" ItemStyle-Width="75px" SortExpression="ICD9">
                            <ItemTemplate>

1.If Intellisense doesn't come for a given code that doesn't mean that code is not valid.

2. I would suggest this update in your code


 <ItemTemplate>
                                <div style="width: 75px; overflow: hidden; white-space: nowrap; word-wrap: break-word;">
                                                                        <asp:TextBox ID="TextBox1" runat="server" Wrap="true"  TextMode="MultiLine" Text='<%# Eval("ICD9").ToString().Replace(",", Environment.NewLine.ToString())%>
' ReadOnly="true">
                                    </asp:TextBox>
                                </div>
                            </ItemTemplate>
                            <EditItemTemplate>
                                <div style="width: 75px; overflow: hidden; white-space: nowrap; word-wrap: break-word;">
                                    <asp:TextBox ID="TextBox1" runat="server" Wrap="true"  TextMode="MultiLine" Text='<%# Eval("ICD9").ToString().Replace(",", Environment.NewLine.ToString())%>

Then the error disappears indeed. But it still has same image in normal mode. In edit mode, each row does have one short string. However I have to use arrow to look up the string.
See the image.

Error must disappear as that's the code I suggested 2 posts back and change your ItemTemplate as well, you are still using old ItemTemplate.
And you have to use arrow 'cause the number of rows you will have is not fixed and it won't do any good t have a very large textarea.

If you must provide the full view then we can increase the rows of textarea. Just bind its Rows property as I have done with Text property.

It is almost there. Two questions.
1. If I use asp.net label instead of textbox, is it possible to wrap the text in normal mode?
2. How to increase the rows of textarea?

1. Depends on many factors basically the style we attach and the style of parent container.
2. Bind its rows properties to
("ICD9").Split(',').Length

Also dont just copy the code, try to understand the trick behind it. Try to understand the trick and you would'nt have to hunt for the code.
