hi DigitalKing & yogsworld! :) you can also try these options: option 1: void Form1_Load() { ... combobox1.SelectedIndexChanged -= new EventHandler(SelectedIndexChanged_Handler); combobox1.DataSource = arr; combobox1.SelectedIndexChanged += new EventHandler(SelectedIndexChanged_Handler); ... } option 2: remove the attaching of the SelectedIndexChanged event handler in the InitializeComponent, then just do it in the Form1_Load after the setting of DataSource property of the combobox. just alternatives instead of using a flag. :) microsoc :cool:

yogsworld wrote: position of null is first why ?????? I explained why. It is a historical thing. Developers who programmed in languages such as C or C++ put null first as a way of protecting themselves by having the compiler flag an error to them. The error being the accidental missing equals sign. = means assignment == means a comparison These two concepts produce radically different results, yet are very very easy to accidentally mix up. Someone typing fast may miss one of the equals signs. In C# the compiler demands that the result of the conditional expression in an if statement evaluates to a Boolean value. I demonstrated the various error messages that the C# compiler would generate that a C or C++ compiler would not likely generate. I should clarify: Putting the null first is not completely the same as putting it second IF there is an error in the code. If the code is written correctly with the double-equals (comparison) operator then the code is the same. Does this make sense?

Hi Yogesh M, The onbeforeUnload event calls the HandleOnClose function which checks if the variable currentElement has a value or not. </head> <body onbeforeunload="HandleOnClose(event)"> <form id="form1" runat="server"> The JavaScript function HandleOnClose checks for this attribute tag of the currentElement object. If currentElement is null or the value of the tag attribute of currentElement is not DonotCallSaveonLoad, then it calls the function FunctiontoCallSaveData; otherwise, the save functionality on the code-behind is called. var keyPressed = ""; //Variable to store which key was pressed var dataChanged = false; var currentElement = ""; //Function called when the browser is closed. function HandleOnClose(evt) { if (currentElement == "" || (!(currentElement.getAttribute("tag")=="DonotCallCloseonLoad"))){ var objconfirm = confirm("Would you like to close the page?") if (objconfirm == true) { FunctiontoDoSomething(); } } } The implementation of the function FunctiontoCallSaveData is the same as previously sent, which is as follows: <script> //Function to submit the form and call the Page_load function on server side. function FunctiontoCallSaveData() { document.getElementById("<%=hdtoSaveData.ClientID %>").value="PageClosed"; document.form1.submit(); } </script> form.submit will in turn call Page_Load in which the Save functionality can be called. Error handling can also be performed for this functionality. Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Try If Not IsPostBack Then LoadControls() End If If hdtoSaveData.Value = "PageClosed" Then Session.Abandon(); End If Catch ex As Exception hdError.Value = ex.Message ExceptionPolicy.HandleException(ex, "SamplePolicy") GetDatafromTable("Error") End Try End Sub Rajendra Prasad Panchati .Net/Sharepoint Software Engineer.

bring the image file into your IDE. In the drop down property box you change the type of resource. Call Assembly.GetManifestResourceStream() This will return a stream. Create a local file with that stream. Refence that file with your Image control. PS: That method is not static so you would either Load the assembly, have a neutral assembly, or grab it from one in memory. The first option being the easiest 1 line of code equals many bugs. So don't write any!!

using setup and deployment wizard you can. You can even specify protocols, port addresses, etc... or just copy the folder over. Nick 1 line of code equals many bugs. So don't write any!!
