I have a datagrid with a few columns. In my ItemDatabound event I would like to show the CollectionDate column based on certain condiition, how do I access the bound column in the item data bound event. The default visibility is set to false for this Collection Date cplumn
<Columns>     
                <asp:TemplateColumn HeaderText="Patient Name"  >
                    <ItemTemplate >
                        <asp:HyperLink ID="hlPatientName" runat="server" NavigateUrl='<%# Eval("PatientId","Patients.aspx?PatientId={0}" ) %>'
                            Text='<%# Eval("PatientName") %>'></asp:HyperLink>
                    </ItemTemplate>
                </asp:TemplateColumn>             
                <asp:BoundColumn HeaderText="Patient ID" DataField="PatientId" Visible="false">
                </asp:BoundColumn>  
                 <asp:BoundColumn HeaderText="OrderID" DataField="Accession" Visible="true">
                </asp:BoundColumn>                
                <asp:BoundColumn HeaderText="Physician Name" DataField="PhysicianName" Visible="true">
                </asp:BoundColumn>  
                 <asp:BoundColumn HeaderText="Collection Date" DataField="CollectionDate" DataFormatString="{0:MM/dd/yyyy}" Visible="false">
                </asp:BoundColumn>

Hi,

Do you want to hide the entire column based on the values of individual rows? or just not show the value of the column for some rows depending on the row values?

Ok, if you want to hide the entire column  you should not do it in the ItemDataBound event, since this event will fire for every row in you datagrid.

So you can define a variable in your page that based in the conditions you want to validate, it will be set to true or false to know if the columns shows up or not.

Public blnShowColumn As Boolean

In you ItemDataBoundEvent make your validations

IF Something = SomethingElse then
   blnShowColumn  = True
Else
   blnShowColumn = False
End if

And just after you Call the DataBind method, hide/show the column

YourDataGrid.Columns(thecolumnidex).Visible = blnShowColumn
