Split long string into many lines in a textbox.

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>
                        </asp:TemplateField>

Are you getting problem in normal mode or in edit mode

Both.

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,

Need code.

Alright

Try this :

<asp:TextBox ID="TextBox1" runat="server" Text='<%# Eval("test").ToString().Replace(",", Environment.NewLine.ToString()) %>' 
                                    TextMode="MultiLine">
                                    </asp:TextBox>

Select allOpen in new window

It doesn't works. The intellsense doesn't show the methods on EditItemTemplate.

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"

I updated it. Both cases are not working.

                            <ItemTemplate>

                                    <%# Eval("ICD9").ToString().Replace(",", Environment.NewLine.ToString())%>
                                </div>
                            </ItemTemplate>
                            <EditItemTemplate>

Line 9

<asp:TextBox ID="TextBox1" runat="server" Wrap="true"  TextMode="MultiLine" Text='<%# Bind("ICD9").ToString().Replace(",", Environment.NewLine.ToString()) %>'>

Bind

should be

Eval

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.

Awesome,

Please correct my code because of exception.

Rows="'<%# Eval
:(

Still wrong.

What exception you are getting?
