rockpune 13-Feb-12 2:39am

sorry sir am newly learning .net where and how to add pre tag pleas tell me.........

lukeer 13-Feb-12 3:13am

The pre tags are not for your C# coding, but for its proper representation here in the forum.

You enclose your code this way:
<pre lang="c#">TypeInYourCodeHere();<pre>
Then the forum displays it in a coding-style font and with nicely coloured key words.

And there is a checkbox "Treat my content as plain text, not as HTML" at the bottom of the edit field. Make shure it is unchecked for the format to take effect.

Solution 1

The parameter type expected is DevExpress.Web.ASPxEditors.ListEditItem but you are trying to use ASPxTextBox1.Text which is of the type System.String.

Solution 3

try

C#

ASPxListBox1.Items.Remove(new ListEditItem(ASPxTextBox1.Text));

or

C#

ASPxListBox1.Items.Remove(FindByText(ASPxTextBox1.Text));

Hi,

I am could not imagine what the purpose of your code…

I fixed the error as mention above...

C#

 using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
//using DevExpress.Web.ASPxEditors;  - This line cause error. Why using this?
//public partial class listboxinsert_delete : System.Web.UI.Page  - This line cause error
public partial class listboxinsert : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    { 
    }
   
    protected void ASPxButton1_Click(object sender, EventArgs e)
    {
        ASPxListBox1.Items.Add(ASPxTextBox1.Text);
        ASPxTextBox1.Text = "";
    }
    protected void ASPxButton2_Click(object sender, EventArgs e)
    {
        ASPxListBox1.Items.Remove(ASPxTextBox1.Text);
    }
}
