Displaying ASPxGridView row index number

You can achieve this through two way:

Method 1

Step 1. Add ASPxGridView on your page:

?

<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="lablel"> </dx:ASPxLabel> </DataItemTemplate> </dx:GridViewDataTextColumn> <dx:GridViewDataTextColumn Caption="User Name" FieldName="UserName" Name="colUserName" VisibleIndex="1" Width="100px"> </dx:GridViewDataTextColumn> <dx:GridViewDataTextColumn Caption="Password" FieldName="Password" Name="colPassword" VisibleIndex="2" Width="30px"> </dx:GridViewDataTextColumn> <dx:GridViewDataTextColumn Caption="Role" FieldName="Role" Name="colRole" VisibleIndex="3" Width="30px"> </dx:GridViewDataTextColumn> </Columns> </dx:ASPxGridView>

Step 2: Add following ASPxGridView Event code snippet to your code – behind file (.cs)

?

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(); }

Method 2

The another way to do it is this one in the Columns section of your GridView control:

?

<dx:ASPxGridView ID="grvTest" AutoGenerateColumns="False" runat="server" DataSourceID="SqlDataSource1" > <Columns> <dx:GridViewDataTextColumn Caption="RowID" Name="colRowID" VisibleIndex="0" Width="20px"> <DataItemTemplate> <dx:ASPxLabel ID="lblRowID" runat="server" Text='<%# Container.ItemIndex + 1 %>'> </dx:ASPxLabel> </DataItemTemplate> </dx:GridViewDataTextColumn>
