I'd like to display a "Description" column in the "Preview" of each Row in the ASPxGrid (8.2.6).  However, when the User Adds / Edits a Row, I want that "Description" column to be editable and display in a MemoEdit.  Is this possible?

Hi Timothy,

Use the PreviewRow and set up your grid like the following:

        <asp:AccessDataSource ID="AccessDataSource1" runat="server" 
            DataFile="~/App_Data/nwind.mdb" 
            SelectCommand="SELECT [CategoryID], [CategoryName], [Description] FROM [Categories]">
        </asp:AccessDataSource>
        <dxwgv:ASPxGridView ID="ASPxGridView1" runat="server" 
            AutoGenerateColumns="False" DataSourceID="AccessDataSource1" 
            KeyFieldName="CategoryID" PreviewFieldName="Description">
            <Settings ShowPreview="True" />
            <Columns>
                <dxwgv:GridViewCommandColumn VisibleIndex="0">
                    <EditButton Visible="True">
                    </EditButton>
                </dxwgv:GridViewCommandColumn>
                <dxwgv:GridViewDataTextColumn FieldName="CategoryID" ReadOnly="True" 
                    VisibleIndex="1">
                    <EditFormSettings Visible="False" />
                </dxwgv:GridViewDataTextColumn>
                <dxwgv:GridViewDataTextColumn FieldName="CategoryName" VisibleIndex="2">
                </dxwgv:GridViewDataTextColumn>
                <dxwgv:GridViewDataMemoColumn FieldName="Description" Visible="False" 
                    VisibleIndex="3">
                    <EditFormSettings Visible="True" />
                </dxwgv:GridViewDataMemoColumn>
            </Columns>
        </dxwgv:ASPxGridView>

Right, that's what I ended up doing, however, my requirements are that the RowEditing be done "Inline".  The "EditFormSettings" do not take effect with Inline-Editing.  May I make a suggestion that there be an additional <InlineEditSettings> tag?

Hi Tim,

Found an answer. Set the visible property to false and enable it using Nathan's approach in this post: How to hide a column in inline edit mode

Except change true/false since you're showing instead of hiding the column.

Amazing!  It works!  Still, it might be easier if there were a <InlineEditSettings> tag for each Column just like the <EditFormSettings> tag .

protected void OnGridStartRowEditing(object sender, ASPxStartRowEditingEventArgs e)
{
     ((ASPxGridView)sender).Columns["Description"].Visible = true;
}

protected void OnGridAfterPerformCallback(object sender, ASPxGridViewAfterPerformCallbackEventArgs e)
{
     if (e.CallbackName == "CANCELEDIT" || e.CallbackName == "UPDATEEDIT")
          ((ASPxGridView)sender).Columns["Description"].Visible = false;
}
