Hi Everybody!!!
I fill a DataGrid with a SQLServer Database, so far so good, but because the name of the fields were thought for internal development work, they're not friendly, so I have to change them, I do that in the ItemDataBound.
But here comes the problem: if I change the headers text, the SortCommand Event doesn't work. what I'm doing wrong? is there another way to change the headers text? or should I bind the grid in another way?
Thanks for your time.
Greetings from Mexico.

Actually the easiest thing to do would be to change the columns names in the query. Like this.
select column1 as NewColomnName from yourTable

Thanks ToddHileHoffer!!!
I did what you told me and it worked!!!
Now I'm just wondering how works the relation between the headers and that event...

You can change the HeaderText with a friendly name, but you can keep the dev name in the SortExpression property of the column?

Hi minhpc_bk!
To your cuestion: No, I can´t. But, but with the advice of ToddHileHoffer all that I had to do was a little function that could make the traslation of the friendly names to the dev names, and that was it.
Greetings.

when you go to this page
http://www1.sprintpcs.com/explore/coverage/CoverageOverview.jsp?ATR_ExtraOne=Personal_Wireless_Plans_Coverage
and enter a zipcode and when u click the 'View coverage' image button, then you get the next page which shows whether you have coverage to the zipcode you entered. But i'm having problem when i do it through Csharp.Net. The problem is the zipcode value is not getting submitted through the image button.
this is the final page where it displays whether it has coverage or not.

Hi,
I'm using my gridview to display my data. I have 2 properties, namely FirstName and LastName. How do I add both of these properties to a single cell?
Currently I have the FirstName displaued like this:
<asp:BoundField DataField="FirstName" HeaderText="Name">
<HeaderStyle CssClass="GridViewHeader" />
<ItemStyle CssClass="GridViewCell" />
</asp:BoundField>
It brings back only the name, I want it to bring back the first and last name and concatenate it as one, or should I just rather create a new property, something like Name?
Please help!!
Regards,
ma se

create a template column and add two labels to it. Add an event of itemdatabound and use the findcontrol method to apply the value.

As Todd said, you can use the Template field in this case with or without two labels controls, and you can use the data binding expression instead of the RowDataBound event to bind data.

If they are not related in any way, then i do not think that this is possible.

I am trying to export data to excel from a datagrid with paging enabled. But while executing an exception is being thrown - "Datagrid link button must be within a form tag with runat="server". This exception is probably due to the link buttons rendered for paging. Please help in this regard.

The CreateUserWizard is nice to use
and saves lots of hassles,
but problem is that when I register a user on my site,
it can't send through the confirmation email.
gmail returns the error message that it needs the connection to be SSL.
below is an extract from http://www.codeproject.com/useritems/SendMailUsingGmailAccount.asp
...
mailMsg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpusessl", "true");
...
but my send mail is not in a method,
how do i make the createUserWizard connect to the smtp with SSL activated?
Thank you

You can create a handler for the SendingMail event of the CreateUserWizard control, and provide your code to send the email in the way you want, you then have to cancel the event.

Hi there!
I'm using a bound dropdownlist as a column in a gridview and using it's Control parameter in an update query.
//Here the GridView
<asp:GridView ID="GridView1" runat="server" DataKeyNames="price_id"
DataSourceID="SqlDataSource1" AutoGenerateColumns="false"
AutoGenerateEditButton="true">
<Columns>
<asp:BoundField HeaderText="Room" DataField="room_number" />
<asp:BoundField HeaderText="Price ID" DataField="price_id"
ReadOnly="true" />
<asp:BoundField HeaderText="State" DataField="state" />
<asp:TemplateField HeaderText="RoomType">
<EditItemTemplate>
<asp:DropDownList ID="DropDownList1"
DataSourceID="SqlDataSource2" DataTextField="room_type"
DataValueField="price_id" SelectedValue='<%#Bind("price_id")%>'
runat="server">
</asp:DropDownList>
</EditItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="MySQL Connection String" ProviderName="System.Data.Odbc"
SelectCommand="SELECT room_number, price_id, state, expiry_date_if_occupied, comments FROM rooms;"
UpdateCommand="UPDATE rooms SET room_number=?, price_id=?, state=?, expiry_date_if_occupied=?, comments=? WHERE room_number=old_?;" OldValuesParameterFormatString="old_{0}">
<UpdateParameters>
<asp:Parameter Name="room_number" />
<asp:ControlParameter Name="price_id" ControlID="DropDownList1"
PropertyName="SelectedValue" />
<asp:Parameter Name="state" />
<asp:Parameter Name="comments" />
<asp:Parameter Name="room_number" />
</UpdateParameters>
</asp:SqlDataSource>
Problem 1
When I run, and try updating I get this exception: "Could not find control 'DropDownList1' in ControlParameter 'price_id'."
Please help me out with what's wrong with the code.
Problem 2
Note: The second BoundField column (Price_ID) binds to the same field as The DropDownList in the TemplateField.
Because of this, I would like to show the DropDownList only when in Edit mode. i.e The BoundField would be for Readonly mode and the DropDownlist for Edit mode.
Problem 3
Am I using the correct OldValuesParameterFormatString with the placeholder? NB: room_number is the key field
Thanks alot good People!
Live in fragments no longer. Only connect.

Prolem1:
You need to include the id of parent control of the dropdownlist (the GridView) in the ControlID of the ControlParameter. The UniqueId of the Dropdownlist can give you a hint.
Problem2:
It seems you state what you have done, but what is your problem? Is your problem that you currently have to use 2 columns for one field price_id? If you want to hide the bound field in the Edit mode, you can set the InsertVisible of the field to false. Another option is to use a label control in the ItemTemplate of the current Template field to display this value instead of using the bound field.
Problem3:
It's not correct:
+ .. WHERE room_number=?; ...
+ Use ConflictDetection="CompareAllValues"
+
...
<asp:Parameter Name="old_room_number" />
</UpdateParameters>
