Hi all,

I'm trying to figure out how to solve this: Could not find control 'GridView3' in ControlParameter 'CourseID'.

Here is the code:

<asp:WebPartZone ID="WebPartZone3" runat="server" HeaderText=".">

<ZoneTemplate>

<asp:GridView ID="GridView3" runat="server" AutoGenerateColumns="False" DataKeyNames="CourseID" DataSourceID="ObjectCoursesDataSource"

SelectedIndex="0" Title="Courses">

<Columns>

<asp:CommandField ShowSelectButton="True" />

<asp:BoundField DataField="CourseID" HeaderText="CourseID" InsertVisible="False"

ReadOnly="True" SortExpression="CourseID" />

<asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" />

<asp:BoundField DataField="Comments" HeaderText="Comments" SortExpression="Comments" />

</asp:GridView>

</ZoneTemplate>

</asp:WebPartZone>

Hi, I'm no expert...but my two cents would be that because of the transformation of the gridview control to a generic web part control, you can't see it (from objectdatasource to zonetemplate). Grouping the gridview and objectdatasource to the same user control and adding that control to the zonetemplate might do the trick.

Please do correct me with a shorter/better solution if you have one

Hi,

Nuwanda is right. Since the control has been wrapped as a generic web part, you can?t access them directly.

Besides, based on your code, I can?t find any controls named ?CourseID?. Do you mean the BoundField with a ?CourseID? DataField? If so, I?m afraid it can?t be a control which can be used in ControlParameter.

Thanks.

Hi Nai-Dong Jin,

The control is the GridView3 and its parameter is the CourseID! it's not the problem though.

To clear my self: There is no problem with the code without the "WebPartZone".

Thanks,

Justuky.
