I was struggling with this issue of trying to reference controls within the same Edit Template, when using the OnCheckChanged method of the Checkbox in the template.  See the solution below. Hope this saves someone some time and effort.

Obtaining values of controls within a EditTemplate when utilizing the OnCheckedChanged method of a checkbox control in the same Template.

This uses a Server Side event. 

protected

void CheckedChanged(object sender, System.EventArgs e)

{

CheckBox chkBox = (sender as CheckBox);

GridDataItem item = (GridDataItem)chkBox.NamingContainer;

RequiredFieldValidator reqval = (RequiredFieldValidator)item["EndDateTime"].FindControl("reqEndDate");

RegularExpressionValidator regexval = (RegularExpressionValidator)item["EndDateTime"].FindControl("regexEndDate");

if (chkBox.Checked)

{

reqval.Enabled =

false;

regexval.Enabled =

false;

}

}

Here is the ASPX

<EditItemTemplate>

<asp:TextBox ID="EndDateTimeTextBox" runat="server" ></asp:TextBox><asp:RequiredFieldValidator

ID="reqEndDate" runat="server" ControlToValidate="EndDateTimeTextBox" ErrorMessage="A valid US Date & Time is Required."

Style="left: 2px; position: relative">*</asp:RequiredFieldValidator><asp:RegularExpressionValidator

ID="regexEndDate" runat="server" ControlToValidate="EndDateTimeTextBox" ErrorMessage="Please enter a valid US Date & Time."

Style="position: relative" ValidationExpression="^(([1-9])|(0[1-9])|(1[0-2]))\/(([0-9])|([0-2][0-9])|(3[0-1]))\/(([0-9][0-9])|([1-2][0,9][0-9][0-9]))\s(1[0-2]|[1-9])\:[0-5][0-9]\s(a|p|A|P)(m|M)$">*</asp:RegularExpressionValidator>

<br />

<asp:CheckBox ID="chkIsFullDay" runat="server" Style="position: relative" Text="Full Day" AutoPostBack="True" OnCheckedChanged="CheckedChanged" />

</EditItemTemplate>
