I have a RadGrid that needs to have dynamic DataSource. The grid will have an A to Z index, where only names started by selected alphabeth is displayed.

When the grid is first loaded, the datasource is by default:

<asp:LinqDataSource ID="ldsMember" ContextTypeName="RedBuckDataContext" TableName="RB_Members" OrderBy="FIFOType" runat="server" />

It loads fine, I can edit, insert and delete columns with no problems.

When an A-Z linkbutton is clicked, the grid's datasource is changed:

                using (RedBuckDataContext rbdc = new RedBuckDataContext())
                {
                    var member = (from m in rbdc.RB_Members
                                  where m.Name.StartsWith(lbAlp.CommandArgument)
                                  select m);

                    rgMember.DataSource = member.ToList();
                }

        rgMember.DataSourceID = null;
        rgMember.DataBind();

The grid displays only data starated with the selected alphabeth, which is good!

The problem is, when I click "Edit" to modify the data, the grid does not display anything. The rows displayed were gone. It is like the datasource has been resetted.

Can anyone please help me on this?

Cheers,

I am using the version 2011.3.1305.35 of the RadGrid and experiencing some strange behavior when the grid is right clicked. Occasionally when a user right clicks the gird to bring up a context menu the row that was right clicked will be selected in addition to any rows that were previously selected. The other times it just displays the context menu without selecting the rows. It seems to be intermittent and I cannot consistently reproduce results. I do not want the additional rows to be selected. Is there any way to trap how a row became selected? The domEvent property of the onrowselecting event args does not look like it has what I need.

 
Here is how i have the grid configured and the code that displays the context menu:
