Automatic TextBox Width

Question

There is a similar thread about this. But I want to have a multiline TextBox with automatic width (fit width to the larger row).

With this code I can have a multiline TextBox (automatic height)

     <div style="float:left; white-space:nowrap ">
        <asp:TextBox style="display:inline; overflow:hidden"  
                     ID="txt1" 
                     runat="server" 
                     Wrap="false" 
                     ReadOnly="true" 
                     TextMode="MultiLine" 
                     BorderStyle="none" 
                     BorderWidth="0">
        </asp:TextBox>
    </div>
    <div style="float:left">
        <asp:TextBox ID="txt2" runat="server" Text="Example textbox"></asp:TextBox>
    </div>

Code behind:

txt1.Rows= text.Split("|").Length ' Sets number of rows but with low performance
txt1.Text = text.Replace("|", Environment.NewLine)

Once again, thanks for your help.

You could try a linq approach:

string[] rows = text.Split('|');
int maxLength = rows.Max(x => x.Length);

txt1.Rows = rows.Length;
txt1.Columns = maxLength;
