I'm having a editable grid view as shown below with a text box in item template and i'm getting a dataset from an oracle ref cursor and assigning it to the gridview datasource now i want to validate the textbox for required field validation and simultaniously check whether the user entered a number instead of alphabets using regex?

anyone who has ideas are welcomed to share their thoughts below is the gridview control design(source)

thanks in advance

<asp:GridView ID="gvRevenue" runat="server" AutoGenerateColumns="False"
GridLines="None" onrowdatabound="gvRevenue_RowDataBound" cellspacing="10">

<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("INDENT1") %>'></asp:Label>
</ItemTemplate>
<ItemStyle VerticalAlign="Top"/>
</asp:TemplateField>
<asp:TemplateField>

You can use RequiredFieldValidator and RegularExpressionValidator on GridView's TextBox as:

<asp:GridView ID="gvRevenue" runat="server" AutoGenerateColumns="False" 
GridLines="None" onrowdatabound="gvRevenue_RowDataBound" cellspacing="10">

<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("INDENT1") %>'></asp:Label>
</ItemTemplate>
<ItemStyle VerticalAlign="Top"/>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text='<%# Bind("INDENT2") %>'></asp:Label>
</ItemTemplate>
<ItemStyle VerticalAlign="Top"/>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="Label3" runat="server" Text='<%# Bind("DESCRIPTION") %>'></asp:Label>
</ItemTemplate>
<ItemStyle VerticalAlign="Top" Height="20"/>
</asp:TemplateField>
<asp:TemplateField Visible="false">
<ItemTemplate>
<asp:Label ID="Label4" runat="server" Text='<%# Bind("BOLD") %>'></asp:Label>
</ItemTemplate>
<ItemStyle VerticalAlign="Top" />
</asp:TemplateField>
<asp:TemplateField Visible="false">
<ItemTemplate>
<asp:Label ID="Label5" runat="server" Text='<%# Bind("AMOUNTDISPLAY") %>'></asp:Label>
</ItemTemplate>
<ItemStyle VerticalAlign="Top"/>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("AMOUNT") %>'></asp:TextBox>
<asp:RequiredFieldValidator ControlToValidate="TextBox1" Text="*" runat="server" SetFocusOnError="true"/>
 <asp:RegularExpressionValidator ID="regexpTGridText" runat="server"     
                                    ErrorMessage="*Invalid" 
                                    ControlToValidate="TextBox1"     
                                    ValidationExpression="[0-9]*" />
</ItemTemplate>
<ItemStyle VerticalAlign="Top"/>
</asp:TemplateField>
</Columns>
</asp:GridView>
