Adding a validator to the gridview textbox, created in edit-mode of a bound field
- by user181218
Hi,take a look at this sample code: (question bellow)
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AllowSorting="True" DataSourceID="SqlDataSource2"
AutoGenerateColumns="False" onrowupdated="GridView1_RowUpdated"
DataKeyNames="Product_Id">
<Columns>
<asp:ImageField DataImageUrlField="Image_Name" HeaderText="Image_Name"
ReadOnly="True" >
<ItemStyle Width="50px" Height="50px" Wrap="true"/>
</asp:ImageField>
<asp:BoundField DataField="Product_Id" HeaderText="Product_Id"
InsertVisible="False" ReadOnly="True" SortExpression="Product_Id">
</asp:BoundField>
<asp:BoundField DataField="Product_Name" HeaderText="Product_Name"
SortExpression="Product_Name" />
<asp:BoundField DataField="Category_Name" HeaderText="Category_Name"
SortExpression="Category_Name" ReadOnly="true" />
<asp:BoundField DataField="Description" HeaderText="Description"
SortExpression="Description" />
<asp:BoundField DataField="Size" HeaderText="Size"
SortExpression="Size" />
<asp:BoundField DataField="Price" HeaderText="Price"
SortExpression="Price" />
<asp:CommandField ShowEditButton="True" />
<asp:CommandField ShowDeleteButton="True" />
</Columns>
</asp:GridView>
Assume I initialize an SqlDataSource, add a parameter and so on.
The thing is, that when a user clicks edit we get a textbox to edit the colnumn value.
I want to validate the data enter by the user before the update is performed and the new
data is propagated back to the server.How?
10x a lot!
