Override Datagrid from function

[Ralf Rennartz]

Hello NG,

i have the following function which works fine:

Public Shared Function getFullDatagrid () As
System.Web.UI.W ebControls.Data Grid

Dim myGrid As New System.Web.UI.W ebControls.Data Grid()

Dim bcn1 As New BoundColumn()

bcn1.HeaderText = "T55"

bcn1.DataField = "DocumentID "

myGrid.Columns. Add(bcn1)

myGrid.Enabled = True

myGrid.EnableVi ewState = True

myGrid.DataSour ce = getData("test")

myGrid.DataBind ()

Return myGrid

End Function
In Page_Load i call the function:

DataGrid1 = getFullDatagrid ()

But the datagrid is not displayed. All the propertys like
"DataGrid1.Colu mns.Count" , "DataGrid1.Item s.Count" can be shown in a
layer.

Do you know what is going wrong here?

Thank You
Ralf

Hi

Do you add your newly created control to the page? If you create your control
dynamically you need to add it to the page. The simplest way is to put a
PlaceHolder control at your web page and add your grid to the control by
calling:

PlaceHolder1.Co ntrols.Add(myGr id)

As you create new instance of the control you still need to add this newly
added control to the page. You may try adding it to the same parent control
as the old one which is created by the designer.

Try something like:

Dim temp as DataGrid
temp = DataGrid1
DataGrid1 = getFullDatagrid ()
temp.Parent.Con trols.Add(DataG rid1)

However, I owuld recommend replacing the grid created in designer with PlaceHolder
control and then using dynamic control by adding it to the placeholder.

You are right: Placeholder works fine.
Thanks!
