How to export a gridview content inside a custom email template


This article shows you how to export the content of a gridview in order to display it inside an HTML table for your custom notification.

In the GRIDVIEW_IN_CUSTOM_EMAIL sample process, we’ll be exporting the default gridview sample.

Note: The sample process and code example are provided as-is. You can adapt the code if you want a different style instead of a simple HTML table.


  1. In the form designer, add a new textbox field, which will contain the HTML table of your gridview content.

    • This textbox field can be hidden.

    • Make sure the textbox has a Value Out data specified in the mapping.

  2. In the Form Designer code-behind, add the following code to create new event on the Submit button. This will be the event that generates your gridview’s HTML template.

    protected void Page_Load(object sender, EventArgs e) 
        base.Page_Load(sender, e); 
        submitButton.Click += new EventHandler(MySubmitButton_Click); 
  3. Add the method that will be called by the event on the submit button. To do this:

    1. Create a variable that will contain the value of your HTML table and initiate it with the table header.
    2. Use a loop to go across all the rows of your table. In this example the table ID is REQUEST_GRIDVIEW.
    3. During each loop, you want to add a new row that will contain the value of each of your columns.
    4. After looping all the rows, save the data in the new textbox field you added earlier.
    protected void MySubmitButton_Click(object sender, EventArgs e) 
        var gvContent = "<table><tr><th>Title</th><th>Description</th><th>Price</th></tr>";
        foreach(System.Data.DataRow row in FormData.Tables["REQUEST_GRIDVIEW"].Rows)
            gvContent += "<tr><td>" + row["REQUEST_GRIDVIEW_TITLE"].ToString() + "</td><td>" + row["REQUEST_GRIDVIEW_DESCRIPTION"].ToString() + "</td><td>" + row["REQUEST_GRIDVIEW_PRICE"].ToString() + "</td></tr>";	
        gvContent += "</table>";
        REQUEST_GRIDVIEW_CONTENT.Text = gvContent;
        this.SaveFormData(this.FormData, true); 
  4. On the Data tab, add your custom email template and use the value of your textbox field that contains the HTML table.

    1. Make sure to give a style for your HTML table inside your email template.
    2. Use the <WF_PROCESS_INST_RELDATA_VALUE.(YOUR_DATA_NAME)> macro to retrieve the value of your data to be used in the email.
    <!DOCTYPE html>
       table, th, td {
         border:1px solid black;
       <h2>Here is the process gridview content in the HTML table</h2>
  5. On your action’s Notification tab, create an additional notification that will use your custom email template.
