Callback & passing value

[sbao004]

Hi, I was trying to send a number from a HTML textbox to add a value to it at the Server, then return it to an ASP textbox. But I don't know to to pass the value of the HTML textbox to the server. The 2 Javascript functions are: //the first function to call the server function GetNumber() { UseCallBack(); } // The function receive the adjusted value from the server and display it into the textbox1 function GetRandomNumberFromServer(arg, context) { document.forms[0].TextBox1.value = arg; } Here are the server side code, written in the .vb file: Dim _callbackResult As String = Nothing Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim cbReference As String = Page.ClientScript.GetCallbackEventReference(Me, _ "arg", "GetRandomNumberFromServer", "context") Dim cbScript As String = "function UseCallBack(arg, context) {" & cbReference & "}" Page.ClientScript.RegisterClientScriptBlock(Me.GetType(), "UseCallBack", cbScript, True) End Sub Public Function GetCallbackResult() As String Implements System.Web.UI.ICallbackEventHandler.GetCallbackResult Return _callbackResult End Function Public Sub RaiseCallbackEvent(ByVal eventArgument As String) Implements System.Web.UI.ICallbackEventHandler.RaiseCallbackEvent _callbackResult = 'equal the value from the HTML textbox + 5 End Sub Does anyone know where I can add some code to ask to pass the value to the Server? Thanks,

Hi, As u show here your callback function can pass Argument to server... U just simply put it on your UseCallBack Function of javascript... Use ====================== UseCallBack("Argument u Pass",""); ======================= Now on Server Side U can get this value by RaiseCallBackEvent funtion Like ============================= _callbackResult =eventargs.ToString() // It written in C# ============================= This way u can get Value from javascript to Server ----------------- Viral
