Retrieving non english characters from grid view [SOLVED]

Hello

My database has lots of german data stored. While I read it and display in the gridview, everthing works fine. The Grdview displays the german characters perfectly in the browser.

After the display phase, I read a data from the gridview cells as gridview1.rows[1].cells[2].text, it returns special characters. For eg, 1st row, 2nd column in gridview has ä which is displayed in the browser properly, when I read the same from codebehind, it shows ä

How to set it right? any help is deeply appreciated.

thanks
Kit

That's another representation of the same character; similar to decimal or binary being another representation of a number.

It should display correctly as "A umlaut" when you display it again in the browser, or when you save it to a file. Conversely, you could try to check the string using a Debug.WriteLine statement.

Well, I am acutally exporting the datatable to Excel. And I dont see ä in excel, instead I see the numbers and special characters. How to make the excel display ä?

You can reverse the HTML-coding using the HtmlDecode[^] method Smile | :)

Oh my goodness! This is what I was looking for since noon Smile | :)

Thanks a ton!

PS: Will it be a performance hit if I decode it in a loop which has -say - a 100 iterations?

Not much, it's a fast string-operation. You should be allright Smile | :)

Validation Issue

Hi guys,

I have 3 submit buttons on a single page. Each submit button is linked to its controls via a "ValidationGroup". One of the groups even has a Custom Validator. The problem I am having is that the validation is not even firing. I have no idea why. I hope the answer is not silly Frown | :(

Here is the HTML for ONE of the groups:

<div id="dvRegistrationValidation" runat="server">
                        <asp:RequiredFieldValidator ID="rfvRegistrationCode" ControlToValidate="txtRegistrationCode"
                            Display="None" ValidationGroup="RegistrationProcess" ErrorMessage="Registration Code"
                            runat="server"></asp:RequiredFieldValidator>
                        <asp:CustomValidator ID="cstTarget" runat="server" ErrorMessage="Either Head Office or Farm Site/Unit"
                            ValidationGroup="RegistrationProcess" OnServerValidate="cstTarget_ServerValidate"
                            Display="None"></asp:CustomValidator>
                        <asp:ValidationSummary ID="vsRegistration" runat="server" DisplayMode="BulletList"
                            ShowSummary="true" HeaderText="The following fields are mandatory:" ValidationGroup="RegistrationProcess" />
                    </div>

And here is the OnServerValidate Sub Routine:

Sub cstTarget_ServerValidate(ByVal source As Object, ByVal e As ServerValidateEventArgs) Handles cstTarget.ServerValidate

    If Me.chkTarget1.Checked = True And Me.chkTarget2.Checked = True Then
        e.IsValid = False
    ElseIf Me.chkTarget1.Checked = False And Me.chkTarget2.Checked = False Then
        e.IsValid = False
    ElseIf Me.chkTarget1.Checked = True And Me.chkTarget2.Checked = False Then
        e.IsValid = True
    ElseIf Me.chkTarget1.Checked = False And Me.chkTarget2.Checked = True Then
        e.IsValid = True
    End If

End Sub

I appreciate any help given. Thanks!

Oh dear!

I solved it. just for others to know my silly mistake...

I need to make the "ValidationGroup" for each button of the each group the same as what was applied in the controls of that group.

e.g.

<asp:Textbox id="txt1" runat="server" ValidationGroup="Validation1"></asp:TextBox>
<asp:RequiredFieldValidator id="rfv1" runat="server" ValidationGroup="Validation1"></asp:RequiredFieldValidator>
<asp:Button id="btn1" runat="server" ValidationGroup="Validation1"></asp:Button>
<asp:ValidationSummary id="vs1" runat="server" ValidationGroup="Validation1"></asp:ValidationSummary>

Re: Validation Issue

... and you could reduce the validate method to a simple

e.IsValid = Me.chkTarget1.Checked <> Me.chkTarget2.Checked

If your database is using integrated authentication (looks like it from your trace), have you defined the ASPNET user in the database?

Is this your database? Have you installed it? If not you should the ask the system administrator or whoever created this database to add you (or your aspnet user to the database.
Have you ever connected succesfully to this database? Can you for example use SQL Administrator to browse data?
