Changing or Binding to xamGrid Header Text
posted

I have an issue, that I think would be relatively straight forward, but I can't seem to make it work...

 

In short, I have a xamGrid, that is bound to some item source.  That source is a list of schedule data.  I simply want to change the headers to the dates based on the client's search.  So, I set them to some default like "Data1Text" through "Data7Text".  When the grid loads, I want it to change to something like "Sunday, 9/1/12" (first column header text) through "Saturday, 9/7/12" (last column header text).

 

I am using Template Columns.  I tried binding to the item source...to the view model... it never changes to the date.. below is a code snippet.  If that can't work, then I don't mind changing the column header text after the item source is updated...but I can't figure what event is used for that.  I am using MVVM and Prism framework, if that helps.

 

<ig:XamGrid HorizontalAlignment="Center" Name="xamGrdManageWeeklyPlanner" VerticalAlignment="Top"

ItemsSource="{Binding Path=WPRecords, Mode=TwoWay}" AutoGenerateColumns="False" MinWidth="890" MaxHeight="400"

    Greetings all,

     

    Well, I guess this is what happens when you try to code late... i figured out the fix for this today, it was, as I thought, straight forward.  I had this code in my InitializeRow method for the grid.  Which was right...except I forgot the "_count++" at the end of the foreach... ::sigh:: It is working as expected now.

     

    private void xamGrdManageWeeklyPlanner_InitializeRow(object sender, InitializeRowEventArgs e)
            {
                int _count = 0;
                foreach(var c in e.Row.Columns)
                {
                    switch (_count)
                    {
                        case 0:
                            break;
                        case 1:
                            c.HeaderText = (this.DataContext as vmSchSchedule).Data1Text;
                            break;
                        case 2:
                            c.HeaderText = (this.DataContext as vmSchSchedule).Data2Text;
                            break;
                        case 3:
                            c.HeaderText = (this.DataContext as vmSchSchedule).Data3Text;
                            break;
                        case 4:
                            c.HeaderText = (this.DataContext as vmSchSchedule).Data4Text;
                            break;
                        case 5:
                            c.HeaderText = (this.DataContext as vmSchSchedule).Data5Text;
                            break;
                        case 6:
                            c.HeaderText = (this.DataContext as vmSchSchedule).Data6Text;
                            break;
                        case 7:
                            c.HeaderText = (this.DataContext as vmSchSchedule).Data7Text;
                            break;
                        default:
                            break;
                    }
                    _count++;
                }
            }
