HtmlDataCellPrepared versus HtmlRowPrepared at DevExpress ASPxGridViews

I had a problem in crafting hyperlinks within a DevExpress ASPxGridView like this in that when I had a JavaScript effect which had to happen upon a mouseover like so:

hyperLink.Attributes.Add("onmouseover", String.Format("ShowToolTips('{0}','{1}',',')", hyperLink.ClientID, _errors));

 
 

...there was a problem! One had to click in the page before the mouseover effect would work! At my wireup like this...

Foo.HtmlDataCellPrepared += Foo_HtmlDataCellPrepared;

 
 

...which used a method such as this...

private void Foo_HtmlDataCellPrepared(object sender, ASPxGridViewTableDataCellEventArgs e)
{

 
 

...I ended up giving up on an expectation of hyperlink management. I instead added a new wireup like this...

Foo.HtmlRowPrepared += Foo_HtmlRowPrepared;

 
 

...which used a method such as this...

private void Foo_HtmlRowPrepared(object sender, ASPxGridViewTableRowEventArgs e)
{

 
 

...which could affect a column like this...

<dx:GridViewDataTextColumn Caption="Validation" Width="80px">
   <DataItemTemplate>
      <asp:HyperLink ID="ValidationLinkButton" runat="server" CausesValidation="false"
            CssClass="FooErrorLink">
      </asp:HyperLink>
   </DataItemTemplate>
</dx:GridViewDataTextColumn>

 
 

...like so:

private void Foo_HtmlRowPrepared(object sender, ASPxGridViewTableRowEventArgs e)
{
   var grid = sender as ASPxGridView;
   if (grid == null) return;
   var hyperLink = grid.FindRowCellTemplateControl(e.VisibleIndex, null,
         "ValidationLinkButton") as HyperLink;
   if (e.RowType == GridViewRowType.Data && hyperLink != null)
   {
      var foo = grid.GetRow(e.VisibleIndex) as Foo;
      if (!string.IsNullOrEmpty(foo.FlattenedErrorList))
      {
         hyperLink.Text = "Error";
         hyperLink.Enabled = false;
         hyperLink.Attributes.Add("onmouseover", String.Format("ShowToolTips('{0}','{1}',',')",
               hyperLink.ClientID, _errors));
      } else {
         hyperLink.Visible = false;
      }
   }
}

 
 

Hmmm... as I type this I'm not sure this had to be done. I also changed a CSS class at the links and that helped big. :P
