[Solved] ! Error On Group on drag and drop

[Pierre]

Hi,
I try to grouping by expression on drag and drop. I use the expression from documentation as codebehind C#. But No solution only errors.
What are the problem?

ASPX

<radGrid:RadGrid ID="gridContacts" OnNeedDataSource="gridContacts_NeedDataSource" AutoGenerateColumns="false" SkinsPath="~/Sitefinity/Admin/Themes/Default/Skins/Grid" Skin="Sitefinity"
                    OnItemCommand="ContactsGrid_Command" runat="server"
                    GridLines="None" Width="95%" AllowPaging="true" AllowSorting="True" PageSize="25" ShowGroupPanel="true" OnGroupsChanging="RadGrid1_GroupsChanging" GroupingEnabled="true" ClientSettings-AllowDragToGroup= "true" >
                    <ClientSettings AllowDragToGroup="True" />
                    <AlternatingItemStyle BackColor="#FFA500"  />
                    <ItemStyle BackColor="#FFFFFF"  />
                    <GroupPanel PanelStyle-Height="25px"/>
                    <HeaderStyle Height="25px" BackColor="#637783"  />
                    <GroupHeaderItemStyle Height="20px" />

                    <MasterTableView DataKeyNames="NbClients" AllowMultiColumnSorting="true" >
                        <Columns>

I use the Code from Documentation : Grouping in Drag and drop

Message d'erreur du compilateur: CS0019: L'opérateur '==' ne peut pas être appliqué aux opérandes de type 'Telerik.Web.UI.GridGroupsChangingAction' et 'Telerik.WebControls.GridGroupsChangingAction'

Ligne 207 :        {
Ligne 208 :            if (e.Expression.GroupByFields[0].FieldName != "NbClients")

 Without == but only =

Hello Pierre,

It seems that you have a mix between Telerik.WebControls.RadGrid and Telerik.Web.UI.RadGrid classes:

'Telerik.Web.UI.GridGroupsChangingAction' et 'Telerik.WebControls.GridGroupsChangingAction'

Please use one of them only!

Hi,

Thanks, you are right, but I use Sitefinity, how to select the SkinPath needs in Sitefinity using RadGrid prometeus, No skinPath only Skin and SkinID.

Hello Pierre,

You need to set the full name for the GridGroupsChangingAction parameter in RadGrid1_GroupsChanging event handler. If you want to use RadGrid control, RadGrid1_GroupsChanging method should look as follows:

private void RadGrid1_GroupsChanging(object source, Telerik.WebControls.GridGroupsChangingEventArgs e)
{
   ...

Here is the declaration for RadGrid "Prometheus":

 private void RadGrid1_GroupsChanging(object source, Telerik.Web.UI.GridGroupsChangingEventArgs e)
{
   ...

Hope this helps.
