Find controls in the DataItem template of ASPxGridView column

Add DataItemTemplate to Grid Column to access at server side code. In case of DataRowTemplate, we create template for whole row, but if we want to create template for a single column then we use DataItemTemplate and on the place of DataRowTemplate’s
((sender as ASPxGridView).FindRowTemplateControl(..) method; here we use FindRowCellTempleteControl(..) method on HtmlRowCreated event of ASPxGridView.

Grid Markup:

  <dx:ASPxGridView ID="grvTest" AutoGenerateColumns="False" runat="server" DataSourceID="SqlDataSource1"
        OnHtmlRowPrepared="grvTest_HtmlRowPrepared" OnHtmlRowCreated="grvTest_HtmlRowCreated">
        <Columns>
            <dx:GridViewDataTextColumn Caption="RowID" Name="colRowID" VisibleIndex="0" Width="20px">
                <DataItemTemplate>
                     <dx:ASPxLabel ID="lblRowID" runat="server" Text='Label'>
                    </dx:ASPxLabel>
                </DataItemTemplate>
            </dx:GridViewDataTextColumn>

C#

protected void grvTest_HtmlRowCreated(object sender, ASPxGridViewTableRowEventArgs e)
        {
            if (e.RowType != GridViewRowType.Data) return;

            ASPxLabel label = grvTest.FindRowCellTemplateControl(e.VisibleIndex, null, 
            "lblRowID") as ASPxLabel;
            label.Text = (e.VisibleIndex + 1).ToString();
        }
