[Solved] Important breaking changes in Q3.09 needing help to migrate

[CSurieux]

Hello,

My code running since long time through various version is totally broken by Q3.2009 version.

Main problem is an exception in RadWebControl.LoadPostData: Invalid Json primitive.
Something has been changed in the way RadDock save its data, i am using a code common from forum to save the Dock position, something like this:

/// Called by DockLayout just after Init
        protected void RadDockLayout1_LoadDockLayout(object sender, DockLayoutEventArgs e)
        {           foreach (DockState state in CurrentDockStates)
            {
                                e.Positions[state.UniqueName]   =   state.DockZoneID;
                e.Indices[state.UniqueName]     =   state.Index;
            }
}

and

/// Called by DockLayout just after PreRender
        protected void RadDockLayout1_SaveDockLayout(object sender, DockLayoutEventArgs e)
        {
            //Save the dock state in the session. This will enable us
            // to recreate the dock in the next Page_Init.
            List<DockState> lst     =   RadDockLayout1.GetRegisteredDocksState();
            CurrentDockStates       = lst;
        }

Second problem is that the grid I was installing in a dock to take its full width seems now greater that the available space and it generate scrollers ! Very ugly !!!

The code which was working without scrollers

<telerik:RadDockLayout runat="server" ID="RadDockLayout1">
<telerik:RadDock ID="GridDock" Title="SELECTED" Top="150px" Left="70%"
    style=" margin-left:auto; margin-right:auto; min-width:305px;min-height:200px;" DefaultCommands='PinUnpin' Pinned="false" DockMode="Floating"
        runat="server" >
        <Commands>
        <telerik:DockPinUnpinCommand  AutoPostBack="true" />
        </Commands>
        <ContentTemplate>
        <telerik:RadGrid ID="RadGrid2" runat="server" GridLines="None" AutoGenerateColumns="False" style=" border-left-width:0; border-right-width:0; border-top-width:0; border-bottom-width:1; border-bottom-style: solid; width:303px;min-height:200px;" >
        <MasterTableView>
            <ExpandCollapseColumn Visible="False" Resizable="False">
                <HeaderStyle Width="20px" />
            </ExpandCollapseColumn>
            <RowIndicatorColumn Visible="False">
                <HeaderStyle Width="20px" />
            </RowIndicatorColumn>
            <Columns>
                <telerik:GridBoundColumn DataField="Name" HeaderText="NAME"
                    ItemStyle-Width='200px' UniqueName="Name">
                </telerik:GridBoundColumn>
                <telerik:GridBoundColumn DataField="Parameter" HeaderText="PARAMETER"
                    ItemStyle-Width='200px' UniqueName="Parameter">
                </telerik:GridBoundColumn>
            </Columns>
        </MasterTableView>
        </telerik:RadGrid>
        </ContentTemplate>
    </telerik:RadDock>
</telerik:RadDockLayout>

Thanks for urgent help.

More...

When collapsed the RadDock now show a funny bottom border made of a serie of helf-circles and under this I get something strange certainly part of the radgrid header but with vertical separators...
Theme Vista, Web20 I have no more tested but seems general.
funny but broken a lot.

Hi Christian,

With the 2009/Q3 release we introduced a new rendering of RadDock for ASP.NET AJAX control. To remove the scroll bar which appears you should set a bigger min-width to the RadDock control, e.g.

<telerik:RadDockLayout runat="server" ID="RadDockLayout1">
          <telerik:RadDock ID="GridDock" Title="SELECTED" Top="150px" Left="70%"
          Style="margin-left: auto;
              margin-right: auto; min-width: 320px; min-height: 200px;" DefaultCommands='PinUnpin'
              Pinned="false" DockMode="Floating" runat="server">
              <Commands>
                  <telerik:DockPinUnpinCommand AutoPostBack="true" />
              </Commands>
              <ContentTemplate>
                  <telerik:RadGrid ID="RadGrid2" runat="server" GridLines="None" AutoGenerateColumns="False"
                      Style="border-left-width: 0;
                      border-right-width: 0;
                      border-top-width: 0; border-bottom-width: 1;
                      border-bottom-style: solid; width: 303px; min-height: 200px;">
                      <MasterTableView>
                          <ExpandCollapseColumn Visible="False" Resizable="False">
                              <HeaderStyle Width="20px" />
                          </ExpandCollapseColumn>
                          <RowIndicatorColumn Visible="False">
                              <HeaderStyle Width="20px" />
                          </RowIndicatorColumn>
                          <Columns>
                              <telerik:GridBoundColumn DataField="Name" HeaderText="NAME" ItemStyle-Width='200px'
                                  UniqueName="Name">
                              </telerik:GridBoundColumn>
                              <telerik:GridBoundColumn DataField="Parameter" HeaderText="PARAMETER" ItemStyle-Width='200px'
                                  UniqueName="Parameter">
                              </telerik:GridBoundColumn>
                          </Columns>
                      </MasterTableView>
                  </telerik:RadGrid>
              </ContentTemplate>
          </telerik:RadDock>
      </telerik:RadDockLayout>
