row is visible=false.

How can get the text of this> gridInboxMessage.Rows[index].Cells[0].Text does not return value

If row is visible=true then by gridInboxMessage.Rows[index].Cells[0].Text I can get text.

Answer 1

You can do it with setting display:none on that column. This is less code, only adding a css on the column you want invisible

<style type="text/css">
    .hiddencol
    {
        display:none;
    }

</style>

<asp:GridView Width="700" ID="gridInboxMessage" runat="server" DataSourceID="LinqDataSource1">
<columns>
    <asp:boundfield datafield="ProductID" itemstyle-cssclass="hiddencol" />
    <asp:boundfield datafield="Name" headertext="Product Name" />
    <asp:boundfield datafield="ProductNumber" headertext="Product Number" />
</columns>
</asp:GridView>
