ASP.NET - Setting Height & Width to a multiline TextBox as per the data in it

Asked By Muzaffar Mohammed on 26-Oct-10 08:39 AM

I have a MultiLine TextBox to which I add text like this:

TextBox tb4 = new TextBox();

tb4.TextMode = TextBoxMode.MultiLine;

tb4.BorderWidth = 0;

tb4.Attributes.Add("style","overflow :hidden");

tb4.Text = //data form database

Every time i execute the code, i'll get different data with different size(Width & Hieght)

How can I set the height & width of the TextBox to be exactly right to display all the content?

Hi,

Try this

TextBox tb4 = new TextBox();

tb4.TextMode = TextBoxMode.MultiLine;

tb4.BorderWidth = 0;

tb4.Style.Add("Height",height);//height=string which holds ur custom value

tb4.Style.Add("Width",width);//width=string which holds ur custom value

Hi,

you can do this pro grammatically by calculating rows and colums...

TextBox tb4 = new TextBox();

tb4.TextMode = TextBoxMode.MultiLine;

tb4.BorderWidth = 0;

tb4.Attributes.Add("style","overflow :hidden");
string strText = //data form database;

tb4.Text = strText;

string[] strArr = strText.Split("\n".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);

      if (strArr.Length == 0)
      {
        tb4.Rows = 1;
      }
      else
      {
        int iColSize = 0;
        foreach (string str in strArr)
        {
          if (iColSize < str.Length)
          {
            iColSize = str.Length;
          }

        }
        tb4.Rows = strArr.Length + 1;
        tb4.Columns = iColSize;
      }

hi,

instead of textbox, use literal control in your page.

<asp:Literal id="lit" runat="server" />

// codebehind

lit.Text = "Your text here"
