DataGrid hidden field

Maziar Aflatoun

Hi everyone,

I have the following code and I like to add a hidden field in each row

<asp:datagrid id="DataGrid1" style="Z-INDEX: 102; LEFT: 48px; POSITION:
absolute; TOP: 40px" runat="server"
AutoGenerateCol umns="False" >
<Columns>
<asp:TemplateCo lumn>
<ItemTemplate >
<asp:Checkbox ID="chkSelectio n" Runat="server"> </asp:Checkbox>
</ItemTemplate>
</asp:TemplateCol umn>
<asp:BoundColum n DataField="Firs tName"
HeaderText="Fir stName"></asp:BoundColumn >
<asp:BoundColum n DataField="Last Name"
HeaderText="Las tName"></asp:BoundColumn >
</Columns>
</asp:datagrid>

Ex. something like
<asp:BoundColum n DataField="Firs tName"
HeaderText="Fir stName"></asp:BoundColumn >
<asp:BoundColum n DataField="Last Name"
HeaderText="Las tName"></asp:BoundColumn >
<input type="hidden" name="myhidden" value="<%#
DataBinder.Eval (Container.Data Item, "RowID") %>" runat=server"> which
doesn't work

Any idea?

Thank you
Maz.

Try to add something like this in Page_Load:

DataGrid1.table s(0).columns(4) .visible = false

Add a Databound column to the grid with attribute: visible = false like this

<asp:BoundColum n DataField="RowI D" HeaderText="Row ID" visible="False" ></asp:BoundColumn >

As far as I remember, setting visible="False" results in not sending the
column to the client. If you want the column to get sent to the client. hide
is with a style rule like this:
<head>
....
<style type="text/css">
..Invisible {display:none}
</style>
....
</head>
<body>
....
<asp:BoundColum n DataField="RowI D" >
<ItemStyle CssClass="Invis ible"></ItemStyle>
</asp:BoundColumn >
....
</body>

If you want to reach the field at client, use <TemplateItem > with <input type=hidden>

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
