Hi
I have a datagrid which has 20 rows and 20 columns, 15 of 20 columns
are checkboxs and their headertexts, datafields are dynamic. I need to
loop through the whole page to see if the specific check box cell is
checked or not. The code is as follows:
For rowindex = 0 To myDataGrid.Item s.Count - 1
Dim item As DataGridItem = myDataGrid.Item s.Item(rowindex )
For colindex = 0 To myDataGrid.Colu mns.Count - 1
Dim itemColumn As DataGridColumn =
myDataGrid.Colu mns.Item(colind ex)
Dim cellValue As Boolean
cellValue = CBool(item.Cell s(colindex).Tex t)
If cellValue = True Then
............... ........
Because the cell is check box so "item.Cells(col index).Text" is a
invalid format. I tried another way:
cellValue = item.Cells(coli ndex).FindContr ol(columnId).Ch ecked
The error is "Checked is not a member of Control..."
I saw some of groupers use
((CheckBox)E.It em.FindControl( "id")).Chec ked to get if the box is
checked.
E is variable of DataGridCommand EventArgs, but my e is a
System.Web.UI.I mageClickEventA rgs, so this way doesn't apply to
mydatagrid neither.
I really feel inconvenient that in Visual Studio.NET the cell only has
Text property to get value, it should has Value property and
Value.GetType to decide which value type this cell contains such as
string, integer, boolean?
Any help will be greatly appreciated.

But I used Visual Studio.NET, seems it doesn't support
grid.Item(rinde x,cindex) any more, the error is "Item is not a member
of System...Datagr id", it only has grid.Items(inde x) and this only
returns a cell not the value of this cell.
