How to pass a multiselection to the next page?

(0) ShareShare
ReportReport
Posted on by Xander Vink 2,550

I'm working on some enterprise portal modifications in AX 2012 and ran into the following issue:

I have a listpage with multiselect enabled. The selection made must be passed to the next page, which is opened by clicking a menu item on the actionpane. However, I don't know of any method to get the multiselection of the previous page. When I use an action menu item, I can get the multiselection from the Args parameter (args.multiselectioncontext()), but this parameter is not available when using a URL menuitem. I can get the currently selected record of the previous page, but that's only one record.

So the question is: when originating from a listpage, how do I get the multiselection from the grid of this listpage on the next page?

    Hi Xander,

    I have same problem on it.

    No, sorry, haven't solved this one yet.

    I tried using an action menuitem that calls a class (that will receive the multiselection) to redirect to the next page. That also didn't work as that function call seems to be running in it's own worker thread and doesn't have access to the websession object. See also community.dynamics.com/.../130378.aspx

    have you tried this?

    MultiSelectionHelper selection = MultiSelectionHelper::createFromCaller(_args.caller());

    MyTable myTable = selection.getFirst();

    while (myTable)

    {

       //do something

       myTable = selection.getNext();

    }

    Yes, that works in the normal client or when calling a class with an action menuitem.

    It doesn't work in the EP when you link to a new page from a listpage...

    Hello Xander,

    If you would want multi-selection in an AxGridView. Then you could use checkboxes to select multiple lines/records.

    Step 1: In the asp markup you insert a TemplateField in the AxGridView:

    <asp:TemplateField>

       <HeaderTemplate>

           <asp:LinkButton ID="btnAll" OnClick="btnAll_Click" Text="<%$ AxLabel:@SYS80094 %>" runat="server" />

           <asp:LinkButton ID="btnNone" OnClick="btnNone_Click" Text="<%$ AxLabel:@SYS38159 %>" runat="server" />

       </HeaderTemplate>

       <ItemTemplate>

           <table width="100%">

               <tr>

                   <td align="center"><asp:CheckBox ID="chkSelect" runat="server" /></td>

               </tr>

           </table>

       </ItemTemplate>

    </asp:TemplateField>

    Step 2: For the buttons created a ToggleCheck method in code-behind which loops over the rows in the AxGridView and checks the checkbox:

    protected void btnAll_Click(object sender, EventArgs e)
{
    ToggleCheck(true);
}
protected void btnNone_Click(object sender, EventArgs e)
{
    ToggleCheck(false);
}
protected void ToggleCheck(Boolean _checked)
{
    foreach (GridViewRow row in gvBlogExample.Rows)
    {
        if (row.RowType == DataControlRowType.DataRow)
        {
            CheckBox chk = (CheckBox)row.FindControl("chkSelect");
            chk.Checked = _checked;
        }
    }
}

    STEP 3: Now to know which lines were selected a method was created which loops over all the rows of the AxGridView and returns a Ax container with the selected RecId’s so you could pass the container through to an Ax method which handles processing:
    protected IAxaptaContainerAdapter getChecked()
{
    IAxaptaContainerAdapter con = AxSession.AxaptaAdapter.CreateAxaptaContainer();
    foreach (GridViewRow row in gvBlogExample.Rows)
    {
        if (row.RowType == DataControlRowType.DataRow)
        {
            CheckBox chk = (CheckBox)row.FindControl("chkSelect");
            if (chk.Checked)
            {
                DataSetView dsv = this.DSBlogExample.GetDataSourceView(this.gvBlogExample.DataMember).DataSetView;
                dsv.SetCurrent(row.RowIndex);
                string recid = dsv.GetCurrent().GetFieldValue("RecId").ToString();
 
                con.Add(recid);
 
            }
        }
    }
    return con;
    Hope this helps to solve your problem.

    Regards,
    Mriganka

    Also you can pass this container to another user control page designed in EP.

    Thanks for your reply, but this isn't the solution to the problem.

    This would work when using a regular webpart, but I was talking about a listpage.
