Today we will learn about  How to Create ModalPopUp Control in ASP.NET AJAX. Let me to tell you step by  step..

Requirements

• First we need to create a ModalPopUp control.
• Perform the Data Validation.
• Savi the data to the database.
• Show the saved data in a GridView.

Database Table Structure

create table tbl_ModalPopUp_Sample  
(  
   ID int identity primary key,  
   UserName varchar(50),  
   Mobile_No bigint  
) 

 Procedure 

• Design the Form.
• For this design I am using the UserControl of ASP.Net.
• Drag a Modal Popup to the form.
• Sets its Property.

CancelControlID="btnClose" 

TargetControlID="LinkButton1"

BackgroundCssClass="modalBackground"  

DropShadow="True" 

PopupControlID="ModalBox" (The ID of the Panel or DIV) 

    <asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server"   
        CancelControlID="btnClose" PopupControlID="ModalBox"   
        TargetControlID="LinkButton1" BackgroundCssClass="modalBackground"   
        DropShadow="True">  
        </asp:ModalPopupExtender>  

 We must call the ID of the Panel or DIV at the ModalPopUp PopupControlID=” “ property that we want to show as the design of the ModalPopUp Control.

CSS Class For ModalPopUp

    .modalBackground  
     {         
         background-color: #336699;  
         filter: alpha(opacity=80);  
         opacity: 0.8;  
     }   
      
     .modalBackground:hover    
     {  
         background-color : #CC3300;  
     }

You will find this Page Directive at the page level after adding the ModalPopUp:
