C# - How To Call A Server Side Method On Losing Focus From A Textbox
Jul 23, 2010
I have two textboxes, one isfor 'program' and the other for 'description'. I have a predefined set of programs and it is associated descriptions in the database.
Example : For program named 'Test' it has the description as 'Valid' in the DB Table
For example, when enter a program name in the program textbox as 'Test', its associated description 'Valid' should be populated automatically to the 'Description' TextBox on losing focus from the 'Program' TextBox.
I am using VS2010 and .NET4 for a web app. I have a script manager/update panel that has a couple of grids.
The client just leaves the page opens and views an updated grid every 30 seconds or so.
I want to refresh the grid by calling the server side method to load the grid, but not load the whol page using meta refresh or similar (too much screen flicker and unnecessary bandwith).
Is it possible to set some timer using javascript or something and call a specific server method to refresh controls?
I need to call a c# server method through the javascript. I have a gridview in which i have a column with dropdown list. When i change the dropdown's value i need to call a server side method through javascript and change the value of another text box in the gridview.
I am able to do this on the selected index change. but i am slightly worried about the performance.
I am building a user registration form in asp.net. I want to check if the username is available or not on the leave event of the TextBox. I am not able to get the Leave Event of the TextBox.
I have a textbox in one grid-view column where upon entering a particular value and losing focus of the textbox, should post to the server to get the text validated through a server-side method. If the entry is valid, a result set to fill rest of row cells would be returned, else the bgcolor of the textbox needs to be changed to Red.
I tried posting back through the obvious way, i.e. making the textbox's autopostback as true and wiring up a server-side OnTextChanged event handler to validate the entered value.
It is working with this setup, but is also affecting the remaining page controls behaviour. For example, if I click a button in some other grid after entering some text in the textbox, the OnTextChanged handler gets called thus preventing the button's click event, which I also wish to call to execute its functionality.
As I call the Controller to exit the focus of my textbox? I need to exit the textbox, go to the database to get information that will supplement the information from my form.
I need to databind the gridview inside the Ajax UpdatePanel each time user types letter inside my TextBox control. How to override the TextChange event to force it do postback for me?
<script type="text/javascript"> function ace1_itemSelected(sender, e) { var hdCustID = $get('<%= hdCustID.ClientID %>'); hdCustID.value = e.get_value(); </script> [code]...
How could i call a javascript function in server side. I have to call the javascript function on the click of a linkbutton which inside a repeater control.
I have a web page having asp.net button control and textbox. I want a confirm message box, when someone changes the content of textbox and click on button. If user click on yes then event of button should fire other wise nothing should happen. All I want is to implement AJAX call back, but it is not working with ASP.NET button control.
<asp:CustomValidator ID="valSex" runat="server" ErrorMessage="1.2 <b>Sex</b> not specified"[code]...
When the page is submitted and Sex is not specified, focus is set but the 2 radio buttons are not quite in view, vertical scrolling is required to bring them into view. Shouldn't the Focus() method have brought the focus control into view?
I want to check the entered email id already exists in my database or not. For that I need the Text box lost focus event so that I can call it in update panel trigger asynchronously. whereas in my event I can check whether the entered value exists in database or not.
I Getting A Problem In DataGrid's ItemDataBound Event.

I have a simple WCF service that I call server side from code behind via a service reference. It's used for validation and works and was automatically setup by Visual Studio and is using SOAP I think because the binding is wsHttpBinding.
I want to use the same WCF service, but call it client side from jQuery using ajax(). I'm trying to implement it by way of these instructions.
But if I make the changes to get the client side call working, I have to add the decoration below which I think will break what works on the server side and also change the system.serviceModel section in web.config.
