Reorder Columns

I am using gridView. I have 4 auto-generated columns and 1 created by me. Now the column I generated is displayed first, followed by the auto-generated columns. I want to display the auto-generated columns first and then the generated column.

for this you need to know the data field (the data item you want to bind) and use either template or boundcolumns to accomplish this, e.g .:

automatic generation of column grid

<asp:GridView id="gv" runat="server" AutoGenerateColumns="True">
</asp:GridView>

manually create a column grid



<asp:GridView ID="gv" runat="server" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField HeaderText="My First Column" DataField="myField1" />
        <asp:BoundField HeaderText="My Second Column" DataField="myField2" />
        <asp:BoundField HeaderText="My Third Column" DataField="myField3" />

        <asp:TemplateField HeaderText="My Fourth Column">
            <ItemTemplate>
                <asp:Label ID="lbl" runat="server" Text='<%# Eval("myField4") %>' />
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

You can use either BoundField or TemplateField , with a template you can do a lot more, create a dropdown instead of a label, etc ... in a BoundField, the output will always be a label and you can only format the string value using nomenclature. NET, for example {0: d}

You have more predefined templates to use like checkbox, button, hyperlink, command and image.
