Hi,

I ran you sample and realized that you need to determine if the activecell is part of a GroupByRow and decide what to do if it is.

I added some code to your AllerSuivant event to give you the idea.

Please let me know if you have any questions.

Hi,

I hadn’t heard back from you and I was wondering if you had further questions.

Hi,

I'm sorry but i had other issues and i didn't responde.

Your solution helped me a little bit but i didn't had time to think about it as i wanted, so I have a question about the positionning on the first element of the next group : how can i select it ?

I didn't find if i can do it with the GroupByData or with the Rows and IsSelected properties.

Regards

Hi,

I worked thru your sample again and made modifications to the AllerSuivant function so that it will skip to the next row in a groupby collection or to the next expended groups' first row.

protected void AllerSuivant(object o)
{
 // grille is the xamGrid control
 var grille = ((XamGrid)o);

 //  Determine if the active cell is part of a GroupByRecord and not a DataRecord
 if (grille.ActiveCell is Infragistics.Controls.Grids.Primitives.GroupByCell)
 {
  return;
 }

 // Once you know that the active row is a Row, you acquire the parent GroupByRow
 // the idea is to determine how many rows are in the GroupByRow collection and then
 // ...... move accordingly.

 //gbr is the parent GroupByRow of the current Active cell's Row
 Infragistics.Controls.Grids.Primitives.GroupByRow gbr = (Infragistics.Controls.Grids.Primitives.GroupByRow)(grille.ActiveCell.Row as Infragistics.Controls.Grids.Row).ParentRow;
    
 // Assuming you just want to set the selected row to the next row,
 // skipping to the first in the next groupbyrows when necessary
 // current postion grille.ActiveCell.Row.Index
 // maximum num of rows - grille.Rows.Count

 int gridRowIdx = 0;

 if (grille.ActiveCell.Row.Index < gbr.Rows.Count - 1)
 {
  //increment index to next row in group
  gridRowIdx = grille.ActiveCell.Row.Index + 1;

  this.PersSelected = (Person)gbr.Rows[gridRowIdx].Data;
  gbr.Rows[gridRowIdx].IsSelected = true;
  gbr.Rows[gridRowIdx].Cells[0].IsSelected = true;
  gbr.Rows[gridRowIdx].Cells[0].IsActive = true;
  grille.Rows[gridRowIdx].IsActive = true;
 }
 else
 {
  //need to acquire the next groupbyrow and if it is expanded, set it's first row as active and selected
  // you will also need to consider levels if more than 1 level of grouping
  int gbrRowIdx = gbr.Index;
  for (int idx = gbrRowIdx + 1; idx < grille.Rows.Count; idx++)
  {
   if (grille.Rows[idx] is Infragistics.Controls.Grids.Primitives.GroupByRow)
   {                                          
    if (grille.Rows[idx].IsExpanded)
    {
     Infragistics.Controls.Grids.Primitives.GroupByRow gbrC = (Infragistics.Controls.Grids.Primitives.GroupByRow) grille.Rows[idx];
     gridRowIdx = gbrC.Rows[0].Index;

     this.PersSelected = (Person)gbrC.Rows[0].Data;
     gbrC.Rows[0].IsSelected = true;                           
     gbrC.Rows[0].Cells[0].IsSelected = true;
     gbrC.Rows[0].Cells[0].IsActive = true;
     gbrC.Rows[0].IsActive = true;

     // Break out of for loop
     idx = grille.Rows.Count;
    }
   }
  }

 }          
}

I left in your code for assigning the PersSelected to the data but you should check that is doing what you expected.

Let me know if you have any questions.

Hi Fabian,

Thanks for posting your solution.  I’m sure it will be interesting to others.

Please let me know if you have further questions.

Hi,

I tried you suggestion bu it didn't work, i already had a binding on the ActiveItem and affect it or the element produce the same issue.

But i found a solution by using the following properties :

- ScrollCellIntoView : it shows the good element,

- IsSelected : on the row to highlight it,

- IsActive : on the first cell of the row to get the data of the row.

I attach the solution if anyone else is interest.

Regards ans thanks for the help.

Fabien.
