Form Designer: How to bind a text box field to a global list

Process Design Form Designer

Overview

You can bind a text box field to a global list so that when a user selects an item in a drop-down list, the text box field is then updated with the corresponding value from another column of the global list. In the following example, the list contains TASK_ID as the value and the text box contains the description.

Solution

  1. On the Databind tab, create a drop-down list bound to a global list.

  2. On the Custom attributes tab, call a method on the OnSelectedIndexChanged event and set the autopostback event to true.

  3. Create a text box with the ID DESCRIPTION.

  4. In the .NET code, add the following code to bind the text box to the global list on the SelectedIndexChange event:

private void Task_OnSelectedIndexChanged(object sender, EventArgs e)
{
  WorkflowGen.My.Integration.GlobalLists gl = new WorkflowGen.My.Integration.GlobalLists();
  System.Data.DataTable GLOBAL_LIST_DATA;
  GLOBAL_LIST_DATA = gl.fetchList("GLOBAL_LIST_DATA", "DESCRIPTION", "en-US", "TASK_ID","Equals",REQUEST_TASK_ID.SelectedValue,true);
  REQUEST_DESCRIPTION.Text = GLOBAL_LIST_DATA.Rows[0]["DESCRIPTION"].ToString();
}

Sample process

  1. Download BINDING_FEATUREv1.zip (the process definition), unzip it, and import it into WorkflowGen as a new process.

  2. Download GLOBAL_LIST_DATA.xml.zip (the global list), unzip it, and import it into WorkflowGen as a global list.

  3. Open the BINDING_FEATURE v1 process and click Test.

  4. For Existing Project?, click the Yes radio button, and select a Project Name from the drop-down menu.

  5. For Update existing task?, click the Yes radio button, and select a Task ID from the drop-down menu.

You’ll see that the rest of the fields will automatically be filled with the corresponding information from the global list.

The line in the .NET code:

“GLOBAL_LIST_DATA.Rows[REQUEST_TASK_ID.SelectedIndex - 1][“DESCRIPTION”].ToString();”

should have "REQUEST_DESCRIPTION.Text = " in front of it, no?

Yes, that is correct. Thank you for the feedback.

Hi, is this text box option for databind tab available using the form designer in the wfg v7.5 release? I am not seeing it. If not which release is it added?

HI Karen,

The databind feature is only available for List controls such as ListBox and DropdownListBox .
For other controls, you would need to use the code behind to perform the databind.

Question: How to pass selected value from one dropdown to another in GridView at form level

I have a GridView with two dropdown lists in each row.

  • The first dropdown is bound to a global list named abc.
  • The second dropdown is bound to another source called xyz.

Now, I want the selected value from the first dropdown to act as a filter or input (i.e., as a WHERE condition) for the second dropdown.

Is it possible to pass this selected value to the second dropdown at the form level, and if so, how can I achieve it?
