>>Does anyone know what this means and how to fix it? I followed all of the instructions in the MM.Net documentation. Without defining the bound columns manually the grid shows the data just fine.

>I don't have any experience with Telerik controls at this point but I am wondering if it is necessary to set the DataType property. I set grid >columns manually by setting the HeaderText and DataField only with no problem. What happens if you just reset that one property back to >default? That said the message would lead me to believe the column type being added is not a Telerik type and I wonder if the builder is not >adding the proper type of column. Have you tried to add these columns in code by adding the telerik .web.ui.gridboundcolumn and setting its >properties rather than using the builder?

The System.String is the default for the DataType. Below is the code that the builder generates:

<mm:mmRADGrid ID="MmRadGrid1" runat="server" AccessLevel="Full" 
	BindingSource="Crew" BindingSourceMember="" BindingType="OneWay" 
	ControlID="00000000-0000-0000-0000-000000000000" GridLines="None" 
	IsPostBack="False" ItemIndex="0" SecuritySetup="True" UserFieldName="">
    <MasterTableView AutoGenerateColumns="False">
        <RowIndicatorColumn>
            <HeaderStyle Width="20px"></HeaderStyle>
        </RowIndicatorColumn>

        <ExpandCollapseColumn>
            <HeaderStyle Width="20px"></HeaderStyle>
        </ExpandCollapseColumn>
        <Columns>
	<telerik.web.ui.gridboundcolumn datafield="Crew" headertext="Crew" 
		uniquename="column"></telerik.web.ui.gridboundcolumn>
        </Columns>
    </MasterTableView>

    <FilterMenu EnableTheming="True">
        <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>
    </FilterMenu>
</mm:mmRADGrid>

The VS editor has a problem with the telerik.web.ui.gridboundcolumn.
