Grouping and Summary

Question

User502904657 posted

First post here!

Sorry if I am breaking ediquite.

I have been using the techniques shown here http://www.agrinei.com/gridviewhelper/gridviewhelper_en.htm

Its been working well for me.  My site use VB rather than C#, but it hasn't been an issue until I tried to do some dressing up of the GroupHeader and GroupSummary. 

The site above has the following sample:

protected void Page_Load(object sender, EventArgs e)
{
    GridViewHelper helper = new GridViewHelper(this.GridView1);
    helper.RegisterGroup("ShipRegion", true, true);
    helper.RegisterGroup("ShipName", true, true);

    helper.GroupHeader += new GroupEvent(helper_GroupHeader);

    helper.ApplyGroupSort();
}
 
private void helper_GroupHeader(string groupName, object[] values, GridViewRow row)
{
  if ( groupName == "ShipRegion" )
    {
        row.BackColor = Color.LightGray;
        row.Cells[0].Text = "  " + row.Cells[0].Text;
    }
    else if (groupName == "ShipName")
    {
        row.BackColor = Color.FromArgb(236, 236, 236);
        row.Cells[0].Text = "     " + row.Cells[0].Text;
    }
} 

 

I am having trouble duplicating the following line from the above code into VB.  Any help is appreciated.

    helper.GroupHeader += new GroupEvent(helper_GroupHeader);

Thanks,

Shane.

The same line with out the semicolon should work fine..

helper.GroupHeader += New GroupEvent(helper_GroupHeader)

Please mark as Answered if it helps.

I am trying to make it work in VB.

I get the error that it is an event and cannot be called directly.

I was being dense about vb event handling... I got it figured out!  ;)

BTW...

In case anyone else stumbles across thread...

For Event Handlers:

In C#

helper.GroupHeader += New GroupEvent(helper_GroupHeader)

Is similar to the following in VB:

AddHandler helper.GroupHeader, AddressOf helper_GroupHeader
