ModalPopupExtender is used to open a pop-up or to open a separate ASP.NET page as a pop-up


Introduction


ModalPopupExtender is used to open a pop-up or to open a separate ASP.NET page as a pop-up.
In this example , we will know displaying individual user details using ModalPopupExtender

If you want to use ModalPopupExtender, your website should have ajax controls enabled
Add the below code to  register the Ajax control assembly (make sure the that AjaxControlToolkit.dll file exists in your website



<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="cc1" %>


Please place the script manager tag in your form where you are going to use ModalPopupExtender

<asp:ScriptManager ID="ScriptManager1" runat="server">    </asp:ScriptManager>


Using the code


Now place the following code

<cc1:ModalPopupExtender id="viewProfile" runat="server"  Enabled="true"    TargetControlID="PopUpSpan" PopupControlID="divViewPro"     DropShadow="false" Drag="True" Animations="" CancelControlID="viewProClose" BackgroundCssClass="d-overlay2"/>


Place the below HTML code to display user in  grid

<asp:GridView runat="server" ID="grdPublicDir" AllowPaging="True"                       AllowSorting="True" AutoGenerateColumns="False" CssClass ="listing-table"   Width="100%"   GridLines="None"EmptyDataText="No Records Found"onrowcommand="grdPublicDir_RowCommand" >       <RowStyle/><EmptyDataRowStyle Font-Bold="True" ForeColor="Red" HorizontalAlign="Center" />

  <Columns>    

 <asp:TemplateField HeaderText="">                      

      <ItemTemplate

            <asp:Image ID="imgProfile" ImageUrl=”images/no-image.jpeg” Width="45px" Height="45px" runat="server" />

          </ItemTemplate>

         <ItemStyle Width="7%"/>

   </asp:TemplateField>                                      

 <asp:TemplateField HeaderText="Name" SortExpression="LastName">

     <ItemTemplate>

         <asp:LinkButton ID="lblLname" runat="server" CommandName="ViewProfile" CommandArgument='<%# Eval("id") %>'  Text='<%# Eval("FullName")' Font-Bold="True" CssClass="pink f-size14"></asp:LinkButton>  <br /><asp:LinkButton ID="lbtnView" CommandArgument='<%# Eval("id") %>' CommandName="ViewProfile" runat="server">View&nbsp;Profile</asp:LinkButton>

        </ItemTemplate>

       <ItemStyle Width="20%" />

     </asp:TemplateField>             

  <asp:TemplateField HeaderText="City" SortExpression="City">

        <ItemTemplate>

           <asp:Label ID="lblCity" runat="server" Text='<%#  Eval("City")%>'> <asp:Label>    </ItemTemplate> <ItemStyle Width="16%" />

</asp:TemplateField>                                           

<asp:TemplateField HeaderText="State" SortExpression="State" >

      <ItemTemplate>

  <%# Convert.ToInt32(Eval("State")) == 0 ? "" : Eval("StateName")%>

    </ItemTemplate>  <ItemStyle Width="14%"/> </asp:TemplateField>

  <asp:TemplateField>

<HeaderTemplate > <asp:Label Text="Zip" runat="server" CssClass="pink"></asp:Label>   </HeaderTemplate>

 <ItemTemplate> <%# Convert.ToString(Eval("Zipcode")) == "" ? "Not Specified" : Eval("Zipcode")%>

   </ItemTemplate>

  <ItemStyle Width="12%"/>

 </asp:TemplateField>

  <asp:TemplateField >

  <HeaderTemplate >

       <asp:Label ID="Label1" Text="Phone" runat="server" CssClass="pink"></asp:Label>

    </HeaderTemplate>

  <ItemTemplate>

      <%# Convert.ToString(Eval("Phoneno")) == "" ? "Not Specified" : Eval("Phoneno")%>

    </ItemTemplate>

    <ItemStyle Width="12%"/>

  </asp:TemplateField>

  </Columns><PagerStyle  HorizontalAlign="Right" />

 </asp:GridView>

HTMl code for display popup:

<div id="divViewPro"  runat="server" class="ModalWindow" style="display:none;" ><span id="PopUpSpan" runat="server" style="display:none;"></span>

<div class="popUpclose"><a runat="server" id="viewProClose"> <img src="images/zoom/closebox.png" /> </a></div>

//Table with your controls to display user details

</div>



Server Side Code:
Call the below function (not exactly ) to fill the grid control

  protected void GetUsers ()    {

        DataTable dt;

        dt = Users.getUsers (1);

        DataView dv = dt.DefaultView;

  grdPublicDir.DataSource = dv;

        grdPublicDir.DataBind();

    }

Below function(not exactly)executes when user hits view profile link

protected void grdPublicDir_RowCommand(object sender, GridViewCommandEventArgs e)    {

        if (e.CommandName == "ViewProfile")        {

           ProfileInfo(Convert.ToInt32(e.CommandArgument.ToString()));

           viewProfile.Show();         

        }

    }

  protected void ProfileInfo(int proID)    {

        try        {

            DataTable dt = Validateuser.getprofile(proID);

            if (dt.Rows.Count > 0)            {

//Code to assign values to controls               

}

        }

        catch (Exception ex)        {

 

        }

  }
