There are many alternate ways:- I am not sure why that is not working. If you still want to show something on next page try one of the followings:- 1. I am not sure but on the next page FILE[] method will be available 2. Use Session Variables to store what you want in textbox 3. Added the variable to QueryString ? 4. Use database query to show information on next page.

Dear Sivamyneni, Currently i don't know the problem with DataSource, i think at a time we can add only one datasource. I also couldn't find the listbox.DataBind() and listbox.DataTextField. What version of .NET u r using. By the Way an alternate way i am giving here and try it.. //Connection to database OdbcConnection con = new OdbcConnection("DRIVER={MySQL ODBC 3.51 Driver};server=localhost;database=mysql;uid=root;pwd=mysql"); con.Open(); //Get data from user table OdbcDataAdapter ad = new OdbcDataAdapter("select * from user", con); DataSet set = new DataSet(); ad.Fill(set); //Here is the code to add all the items of the first column of the user table. foreach (DataRow row in set.Tables[0].Rows) { listBox1.Items.Add(row[set.Tables[0].Columns[0]]); } ////ON OTHER EVENT LIKE CHECKBOX OR BUTTON CLICK REPEAT THIS. OdbcDataAdapter ad = new OdbcDataAdapter("select * from BILL", con); DataSet set = new DataSet(); ad.Fill(set); //Here is the code to add all the items of the first column of the bill table. foreach (DataRow row in set.Tables[0].Rows) { listBox1.Items.Add(row[set.Tables[0].Columns[0]]); }

Yes i checked it again. First i have made a usercontrol, then i make a panel on it, then i put all the controls on that. But these all controls (Complete user control), i am adding at runtime on a Autocad Pallate. Problem still exist? Thanks,

Hi sivamyneni, I think when you select one class , the result come in the list box. but when you select the second class , the previos result disappear and the new one shows. I am not sure what method you are using for adding in the list box. Before adding items in the list box , be sure, you should not clear the list. You have to append or insert into the list. If problem not solved, than show the code to me.

Respectfully, First I have added a UserControl, then i have added a panel on it and on the panel i have added a combobox. But on run, when i want to select an item from combobox , it autohide the list. I can select the item by typing. When i click the dropdown button it opens the list. but when i try to select an item. The list get collapsed. Plz solve the Problem. Thanks.
