Ax EP – AxBoundField – OnDataChange Event

Here I want to achieve, if the AxBoundField have some value, need to enable/disable button accordingly.

I had struggled little bit, to raise the event OnDataChanged for AxBoundField control when data changed for this bound control.

Then, have used following markup code for Bound control.

<dynamics:AxGroup ID="AxFieldGroupDefaultsProject" runat="server"

                    Caption="<%$ AxLabel:@SYS4534 %>">

                <Fields>

                    <dynamics:AxBoundField DataSet="TrvExpTableNew" DataSetView="TrvExpTable"

                        DataField="ProjId" SortExpression="ProjId"  AutoPostBack="true" OnDataChanged="ProjId_OnDataChanged"/>

                </Fields>

            </dynamics:AxGroup>

While adding the bound fields to the AxForm, we won’t get this attribute AutoPostBack="true" to the AxBoundField.

To raise the OnDataChanged event,  explicitly need to add the above attribute to AxBoundField.

Then I had added the following code to the event …

protected void ProjId_OnDataChanged(object sender, AxBoundFieldDataChangedEventArgs e)

    {

        string expProjId = ((System.Web.UI.WebControls.TextBox)(e.BoundControl)).Text.ToString();

 

                if (expProjId != "")

                {

                    ButtonOK.Enabled = true;

                }

                else

                {

                    ButtonOK.Enabled = false;

                }          

    }
