Hello,

I have a dropdown in webdatagrid cell and It has two list items bound by asp object datasource. Inital value remains blank but once i make a selection I have to select either of it and I can never clear that cell. I want to be able to clear that cell . In short its a nullable column and the option should be like Y, N and blank(clear the cell).

<ig:DropDownProvider ID="exclPosnDropdown">
<EditorControl ID="exlPosn" runat="server" DisplayMode="DropDownList" DataSourceID="exclPosn" ValueField ="excl_posn_ind_id" TextField="code" >

<DropDownItemBinding TextField="code" ValueField="excl_posn_ind_id" />
</EditorControl>

</ig:DropDownProvider>

</asp:ObjectDataSource>

<asp:ObjectDataSource ID="exclPosn" runat="server" SelectMethod="GetExclPosn"
TypeName="RiskManagementWeb.GridsForms.ModifyPositions" >

</asp:ObjectDataSource>

Please let me know how can I implement this.
