Note (updated on 2009/05/22): do not use this. It is somewhat interesting as an example of how to mess with the web client internals but is too brittle for production code. It will also make your upgrade harder and make it harder for other devs to understand your code. Later I will make a post about how to achieve this same behavior using an unobtrusive, external control that respects the grid’s public API.

If there is one thing that can be said about the datagrid used in the Saleslogix Web Client, it is that it is ugly.  And clunky to use.  OK that makes 2 things, but they both had to be said!  Where is the nice "Add/Edit/Delete" menu that we have on the network client grid?  Instead you have the "Edit" column which is part of the basic ASP.NET datagrid.  Yuk.

Anyway, supposedly there is a revamp in the next version, so I don’t want to spend a major amount of time customizing the current one, but meanwhile I have to have something slightly more usable.  My goals are as follows:

  • Add an "Add" button within the caption of the datagrid (otherwise you have to put it on top of it)
  • Add a double-click action to edit an item
  • Add a "Delete" button within the caption of the datagrid

The Add/Delete buttons will let me emulate a datagrid toolbar which will be useful when the datagrid is embedded within a form, as opposed to being the only control on a tab.

The double-click action is just nicer/better looking than the edit column without being too hard to code.  If I had more time I would try and integrate a third-party control like Telerik or make use of the YUI datagrid but we can’t spend forever on this one.  Another nicety would have been the ability to integrate a control list within the datagrid but again, I got stuck on that one and decided not to waste more time.

Step 1: Add a "ShowAddButton" property to the QFDataGrid

This is not the most straightforward process because the code is pretty closed up, but here is how I did it:

  • Fired up ILDASM, opened the "Sage.SalesLogix.QuickForms.QFControls" assembly, and dumped it to an IL file
  • Edited the IL file and added my property… it looks a bit scary but in reality I just copy/pasted from the "ExpandableRows" property and changed the names:
  .field private bool _showAddButton

  .method public hidebysig specialname instance bool
          get_ShowAddButton() cil managed
    // Code size       7 (0x7)
    .maxstack  8
    IL_0000:  ldarg.0
    IL_0001:  ldfld      bool Sage.SalesLogix.QuickForms.QFControls.QFDataGrid::_showAddButton
    IL_0006:  ret
  } // end of method QFDataGrid::get_ShowAddButton

  .method public hidebysig specialname instance void
          set_ShowAddButton(bool 'value') cil managed
    // Code size       19 (0x13)
    .maxstack  8
    IL_0000:  ldarg.0
    IL_0001:  ldarg.1
    IL_0002:  stfld      bool Sage.SalesLogix.QuickForms.QFControls.QFDataGrid::_showAddButton
    IL_0007:  ldarg.0
    IL_0008:  ldstr      "ShowAddButton"
    IL_000d:  callvirt   instance void [Sage.Platform.QuickForms]Sage.Platform.QuickForms.Controls.QuickFormsControlBase::NotifyPropertyChanged(string)
    IL_0012:  ret
  } // end of method QFDataGrid::set_ShowAddButton

  .property instance bool ShowAddButton()
    .custom instance void [System]System.ComponentModel.BindableAttribute::.ctor(bool) = ( 01 00 00 00 00 )
    .custom instance void Sage.SalesLogix.QuickForms.QFControls.Localization.SRCategoryAttribute::.ctor(string) = ( 01 00 11 43 41 54 45 47 4F 52 59 5F 42 45 48 41
                                                                                                                    56 49 4F 52 00 00 )
    .set instance void Sage.SalesLogix.QuickForms.QFControls.QFDataGrid::set_ShowAddButton(bool)
    .get instance bool Sage.SalesLogix.QuickForms.QFControls.QFDataGrid::get_ShowAddButton()
  } // end of property 
  • Compiled using ilasm /dll
  • Copied the resulting DLL to the PF\Saleslogix\Architect\Saleslogix directory (backup the existing one just in case!)
  • Restarted AA and admired my new property:

ShowAddButton Property

Step 2: Customize the template to show my add button

In the Model\QuickForms\Web you can edit the QFDataGrid.WebControlRenderingTemplate.vm file which controls how the datagrid is rendered to a web form.  Of course, this will all be invalidated by an upgrade etc but we are just playing here.

  • Add the code to show the button (do a search for "mainContentHeader" and replace that entire <div> with the following <table>):
#if((${qfcontrol.Caption} != "") && ($qfcontrol.Visible == true))
<table class="mainContentHeaderTable">
    <asp:Label runat="server" Text="<%$ resources: grdFamily.Caption %>" ></asp:Label>
  <td class="mainContentHeaderToolsRight">
      <asp:ImageButton runat="server" AlternateText="Add Record" id="${qfcontrol.ControlId}_btnAdd"
        OnClick="${qfcontrol.ControlId}_btnAdd_Click" Text="Add"/>
  • Add the code for the button handler (I stole it from the "InsertChildAction" template).  Note that in order for this to work you will need to have added an Edit column (see next section for more on that).  This can be anywhere within the server script of the same template:
protected void ${qfcontrol.ControlId}_btnAdd_Click(object sender, EventArgs e)
  if (DialogService != null)
    DialogService.SetSpecs(${editcolumn.DialogSpecs.Top}, ${editcolumn.DialogSpecs.Left},
        ${editcolumn.DialogSpecs.Height}, ${editcolumn.DialogSpecs.Width},
      #if($editcolumn.DialogSpecs.TitleOverride != "")

    Type entityType = typeof(${qfcontrol.QuickFormDefinition.DefaultNamespace}.${qfcontrol.QuickFormDefinition.EntityTypeName});
    Type childType = typeof(#if($qfcontrol.BoundEntityTypeName != "")
      #end );

    DialogService.EntityType = childType;
    // note that the "SetChildIsertInfo" is not a typo.  Well, it is, but not here.
      childType, entityType,
      // we'll assume that the parent relationship is simply the parent type name... eg Contact -> Account
  • We get something like this:


It is not a beauty, that’s for sure.  But that’s what we get with the built-in dialog service, so if the users can live with the rest of the web app surely they can live with this.

Step 3: the Edit button

The edit button is a bit easier because there is no need to add a separate property – we can just piggyback on the "HasEditColumn" property so we only have to modify the template file.

I added this code in the "RowDataBound" method:

  if(e.Row.RowType == DataControlRowType.DataRow)
      Page.ClientScript.GetPostBackEventReference(${qfcontrol.ControlID}, "Edit$" + e.Row.RowIndex.ToString()));

And optionally add this to comment out the code that creates the edit column (since we don’t need it anymore…):

#macro(doEditCol $col)
## #if(!$IsPrintView && !$qfcontrol.RenderVertical)<asp:ButtonField CommandName="Edit"
##  #if($col.Text != "")Text="<%$ resources: ${qfcontrol.ControlId}.${col.ColumnId}.Text %>"#end
##  #if($col.DataField != "")DataTextField="${col.DataField}"#end
##  #if($col.MultiCurrencyDependent)AccessibleHeaderText="MultiCurrencyDependent"#end
##  #addCommon($col) >
##      #addStyle($col)
##  </asp:ButtonField>
## #end

So you just add your edit column (same as normal) and this cause will call it to be invoked on double click instead of click of the column itself.

Step 4: adding a "Selected" handler and delete button

In order for the Delete button to work we’ll have to be able to select a row.  Of course you need to do that without a postback otherwise it will be agonizingly slow, but this is not too bad.

Since this is going to be used only when the Delete button is shown I added a bit of logic to control that and combined the 2 (technically would be a bit nicer to keep them decoupled but I am getting tired):

  • Handler in the server code (in the RowDataBound handler):
      "${qfcontrol.ControlID}_selectGridRow(this, " + e.Row.RowIndex.ToString() + ")");
  • In the toolbar (next to the Add button code):
    #set($showDeleteButton = true)
    <asp:ImageButton runat="server" AlternateText="Delete Selected" id="${qfcontrol.ControlId}_btnDelete"
      ImageUrl="$generator.getImageResourceURL("Delete_16x16")" UseSubmitBehavior="False"
      OnClientClick="return ${qfcontrol.ControlID}_confirmDelete();"
      OnClick="${qfcontrol.ControlId}_btnDelete_Click" />
  • Change the doDeleteCol macro:
#macro(doDeleteCol $col)
  #if(!$showDeleteButton && !$IsPrintView && !$qfcontrol.RenderVertical)
    <asp:ButtonField CommandName="Delete"
    #if($col.Text != "")Text="<%$ resources: ${qfcontrol.ControlId}.${col.ColumnId}.Text %>" #end
    #if($col.DataField != "")DataTextField="${col.DataField}" #end
    #addCommon($col) >
  • Add a hidden field to store the selected value, and a handler to toggle it:
<script type="text/javascript">
// supporting script for the one-click select needed by the delete button
function ${qfcontrol.ControlID}_selectGridRow(row, rowIndex){
  var hid = $get("<%=${qfcontrol.ControlID}_hidSelectedId.ClientID%>");
    hid.value = "";
    hid.selectedRow = null;
  } else {
      hid.selectedRow.className = hid.selectedRow.className.replace(/rowSelected/, "");
    row.className += " rowSelected";
    hid.selectedRow = row;
    hid.value = rowIndex;

function ${qfcontrol.ControlID}_confirmDelete(){
    alert('Please select a row to delete first.');
    return false
  return confirm('Are you sure you wish to delete this record?');
<asp:HiddenField runat="server" id="${qfcontrol.ControlID}_hidSelectedId"/>
  • And finally (phew), add the server code handler next to the add button handler:
// this retrieves the selected grid index from the hidden field and deletes the corresponding record.
// we assume the user has already been prompted for confirmation on the client side.
protected void ${qfcontrol.ControlId}_btnDelete_Click(object sender, EventArgs e)
  String childId = (String)${qfcontrol.ControlID}.DataKeys[Int32.Parse(${qfcontrol.ControlID}_hidSelectedId.Value)].Value;
  ${qfcontrol.BoundEntityTypeName} childEntity = #if($qfcontrol.DataKeyNames != "Id")
    (${qfcontrol.BoundEntityTypeName})Sage.Platform.EntityFactory.GetByCompositeId(typeof($qfcontrol.BoundEntityTypeName), "${qfcontrol.DataKeyNames}".Split(','), id.Split(','));
  if(childEntity != null){
    ${qfcontrol.QuickFormDefinition.DefaultNamespace}.${qfcontrol.QuickFormDefinition.EntityTypeName} mainentity =
      this.BindingSource.Current as
    if((childEntity.PersistentState & Sage.Platform.Orm.Interfaces.PersistentState.New) <= 0)

Final result

All in all I think this is a good example of how to customize the stock controls.  However since you are still at the mercy of the dialog service there isn’t that much to be gained, especially in light of the amount of work (and the fact that you have to hack it up in the IL which is never all that fun).  If you look at the double-click action alone though this is a pretty big usability improvement and very easy to implement, so it might be worth just doing that part?  Not to mention that it doesn’t require you getting your hands into the IL grease.

Another thing that became (even more) evident to me while developing this is how frustrating the development with QuickForms is.  The feedback cycle is SO long between the time you make a tweak on your form and the time you can actually see it in the web client that it is very, very hard to bear.  Not to mention the number of time AA crashed on me or failed to deploy the content without giving me any error.  There is a lot of work to be done there and in the meantime it may be quicker to simply do it as custom smart parts.

I do like the Velocity templates.  They are primitive but simple and effective. I can’t say I am a fan of programming in notepad though – I think Visual Studio has spoiled me.

I believe another approach could be used to add our own custom controls to the control selection list in AA, which may be a better option for future maintenance (and maybe less development headache since we can move a lot of the work from the template to the custom control). 

And a final note…

Despite the presentation this is not intended to be a step by step guide on “how to get this in your datagrid”. First of all I doubt many will be willing to modify the IL. I also glanced over a few details, and I made a few more changes on the production system to make things smoother. This is more of a “look this CAN be done but omg it is painful” type of post. But if you are really interested in the finer details feel free to contact me.
