Hi Iam trying to get listbox selected value by using thelistbox_Indexchanged event, but I am unable to get the selected index or selected value. Please help me out.

Here's the code I've written so far (dt1 is a DataTable).

protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
    {
        dt1.Clear();
        dt1 = g1.Getusers();
        for (i = 0; i < dt1.Rows.Count; i++)
        {
            if (ListBox1.SelectedValue.ToString() == dt1.Rows[i][1])
            {
                TextBox1.Text = dt1.Rows[i][1].ToString();
                TextBox2.Text = dt1.Rows[i][2].ToString();
                DropDownList1.SelectedValue = dt1.Rows[i][3].ToString();
            }
        }
    }

thanks.

Well, you are comparing:
ListBox1.SelectedValue.ToString() == dt1.Rows[i][1]
Looks like you have not used DEBUGGER and seen the values. it looks to me that the comparison is not correct.

Please debug and see if the values are selected.

One more thing, do make sure that you are not re-binding the LitBox1 with the dataset before this selectedindexchange event fires.

Set the property to AutoPostback true such that whenever selection is done it will get auto postback and then you can see the value in the selected change event.
