Hi all,

I have noticed that if just one row cell has an item which cause the row height to increase, then all the rest of the rows increase in height also.

This is very annoying - any way of stopping the rest of the rows increasing in height??

thanks,


KS

What item is it text, an image, etc.  Also is the cell wrapping if its text?

You can either make that specific cell wider or set Pager-Style wrap = false in the properties of the datagrid

You can solve it in the following way:

On DataGrid_ItemCreatd event:

if (i.Cells[2].Text.Length > 25)
                        {
                              e.Item.Cells[2].ToolTip = e.Item.Cells[2].Text;
                              e.Item.Cells[2].Text = e.Item.Cells[2].Text.Substring(0,22)+"...";
                              
                        }
This will add a tooltip for the items that has length more than 25 character in the datagrid cell and add three dots after the text that has more than 25 characters.

Best, Nauman

Setting wrap to False didn't seem to do anything.

VB Translation:

If i.Cells(2).Text.Length > 25 Then
 e.Item.Cells(2).ToolTip = e.Item.Cells(2).Text
 e.Item.Cells(2).Text = e.Item.Cells(2).Text.Substring(0, 22) + "..."
End If

actually its nothing :) I have something like the following in the code but then I found I can make it more granular:

foreach(DataGridItem i in dgPublicationsList.Items)
                  {
                        
                        HyperLink h = (HyperLink)i.Cells[1].Controls[0];
                        if (h.Text.Length > 40)
                        {
                              h.ToolTip = h.Text;
                              h.Text = h.Text.Substring(0,37)+"...";      
                        }

                        if (i.Cells[2].Text.Length > 25)
                        {
                              i.Cells[2].ToolTip = i.Cells[2].Text;
                              i.Cells[2].Text = i.Cells[2].Text.Substring(0,22)+"...";
                              
                        }
                                                                  
                  }
But you dont need this whole thing in your code ;)

Assuming the cell numbers refer to the template columns in my grid i did this:

Sub Item_Created(ByVal sender As Object, ByVal e As DataGridItemEventArgs) Handles DataGrid1.ItemCreated
        If e.Item.ItemType = ListItemType.Item Then
            If e.Item.Cells(7).Text.Length > 10 Then
                e.Item.Cells(7).ToolTip = e.Item.Cells(7).Text
                e.Item.Cells(7).Text = e.Item.Cells(7).Text.Substring(0, 5) + "..."
            End If
        End If
    End Sub 'Item_Created

And also, set the datagrid option: OnItemCreated="Item_Created"

But it doesnt seem to do anything - am i missing something??

Change If e.Item.ItemType = ListItemType.Item  to
If e.Item.ItemType = ListItemType.Item or e.Item.ItemType = ListItemType.AlternatingItem

Oh well, did this in my ItemDataBound and it worked first time!

If e.Item.ItemType = ListItemType.Item Or _
     e.Item.ItemType = ListItemType.AlternatingItem Then

            Dim thePub As Label
            thePub = CType(e.Item.Cells(7).FindControl("lbl_Publication"), Label)
            If thePub.Text.Length > 25 Then
                thePub.ToolTip = thePub.Text
                thePub.Text = thePub.Text.Substring(0, 22) + "..."
            End If
End if

Upto my boss whether he wants it displayed like this or if he wants to settle for those dirty big rows!!

thanks,

KS
