Hi

I have a little problem with empty cells.
If I set a cell to ""  the cell return &nbsp
I understand this.

I would like to know if there is a way that cell.text return nothing.

Actualy I have to put a lot of if in order to have the good result.

For

Each item As GridDataItem In Grille.Items 
  
If item.Selected Then 
    
If item("Tel.").Text <> "&nbsp;" Then ZTel.Text = item("Tel.").Text Else ZTel.Text = "" 
    If item("Nom").Text <> "&nbsp;" Then ZNom.Text = item("Nom").Text Else ZNom.Text = "" 
    
If item("Soc").Text <> "&nbsp;" Then ZSoc.Text = item("Soc").Text Else ZSoc.Text = "" 
    
If item("Lieu").Text <> "&nbsp;" Then Zlocal.Text = item("Lieu").Text Else Zlocal.Text = "" 
    
If item("Prenom").Text <> "&nbsp;" Then ZPrenom.Text = item("Prenom").Text Else ZPrenom.Text = "" 
    
If item("Gsm").Text <> "&nbsp;" Then Zgsm.Text = item("Gsm").Text Else Zgsm.Text = "" 
    If item("Servic").Text <> "&nbsp;" Then Zservice.Text = item("Servic").Text Else Zservice.Text = "" 
    
If item("email").Text <> "&nbsp;" Then Zemail.Text = item("email").Text Else Zemail.Text = "" 
    
If item("titre").Text <> "&nbsp;" Then Ztitre.Text = item("titre").Text Else Ztitre.Text = "" 
    
If item("Sam").Text <> "&nbsp;" Then ZSamSec.Text = item("Sam").Text Else ZSamSec.Text = "" 
    
If item("Sec").Text <> "&nbsp;" Then Zsec.Text = item("Sec").Text Else Zsec.Text = "" 
    
If item("Telsec").Text <> "&nbsp;" Then Zsectel.Text = item("Telsec").Text Else Zsectel.Text = "" 
    Exit For
  End If
Next


Is there a best way ???

Thanks all

Hello Filleau,

I suppose this approach may give you some ideas:

C#:
foreach (GridDataItem item in RadGrid1.MasterTableView.GetSelectedItems()) 
    foreach (GridColumn col in RadGrid1.MasterTableView.RenderColumns) 
        (FindControl("Z" + col.UniqueName) as TextBox).Text = (item[col.UniqueName].Text != "&nbsp;") ? item[col.UniqueName].Text : null
 

VB:
 For Each item As GridDataItem In RadGrid1.MasterTableView.GetSelectedItems() 
     For Each col As GridColumn In RadGrid1.MasterTableView.RenderColumns 
         TryCast(FindControl("Z" + col.UniqueName), TextBox).Text = IIf((item(col.UniqueName).Text <> "&nbsp;"),item(col.UniqueName).Text,Nothing
     Next 
 Next

Thanks Daniel

Your approach is very good, but I'm affraid it will more optimize the number of line code than the application speed.

What I'm looking for is to improve performance.

So what il would like to do will be to delete all the tests (if) but I don't want to see "nbsp," in my text box  if my cell grid is √©qual to Nothing.

Hello Filleau,

You can choose either approach depending on your scenario. Other solution would be to use ItemDataBound event, but you will also have to check for nbsp content.
