(2.0) GridView and BLL ?

[TipGiver]

In my previous thread thread855-1349928 ca8msm helped me to accomplish a part.

This now is quite similar. I can get the fields from the db sane way.. have the datasource auto-generated as i drag and drop the table from the server explorer. Some fields are encrypted. I need to show them de-crypted.

I converted the bound fields into templates, and in the ItemTemplate there is a label (in edit template a textbox). Can this be done directly in xml somehow like: text=MyEncyptionClass.Decrypt('<%# Bind("EncryptedField") %>') ?

Or this is BLL and I need to bind a class (object) ?

Thanks

You can use the same technique as I suggested in thread855-1350288 although you'll have to use the RowDataBound event as you are using a GridView.

Obvioulsy i will use the e.Row.WhatNow ? The DataItem ?

Sorry to ask those silly questions, but this is the first time i use asp.net for a real project and with the use of the gridview

To access a Label control, you will have to use the FindControl method. You can use "e.Row.FindControl" to find a control in the row or "e.Row.Cells(0).FindControl" to find a control in a particular cell.

So this : <asp:BoundField DataField="UserID" ... > should be converted into a template (label for example) ?

Thanks so far !

I thought that is what you had already done:

I converted the bound fields into templates, and in the ItemTemplate there is a label

You don't have to convert each type of column to a template column, but if you need to manipulate the data and/or the output, I find it easier to do so.

Hi,

I was having experiments. That's why i asked this.
The findcontrol succeeded and i applied the decryption i needed. Thanks for that.

You said that this "template transform" is easier; Can you point me something to read and learn about the harder way ?

 

[ca8msm]

It's not so much harder, it's just that you don't have as much control as you will only get acces to the Text rather than an actual control. I think the only difference is that you will access the text via e.Row.Cells(0).Text but I'm not in a position to try this at the moment.

No problem.. I will try it

 

[TipGiver]

I have an other question on this issue, so i dont open a new thread:
Can i join strings in the xml code? In a template label I have: Text='<%# Bind("FirstName") %>'
Can i add infront a "Name: " ? Whatever combinations i made, i get that the server tag is not well formed, and to check the quotes to match.

Thanks again.

Why not just have another Label for that?
