Hi,

I have a detailsview control with a textbox control containing a date.

In edit and insert mode the date field is completed by picking a date from a popup calendar using javascript. All this works fine.

Except the user can modify the textbox causing invalid data.

How can I prevent the user from altering the data in the textbox.

If the textbox is "readonly" it is not bound to the datasource.

If "disabled=true" in html then javascript cannot change the value and data is not bound.

Can anyone help?

Regards,

Lionel

Add CompareValidator to your TextBox:

<asp:CompareValidator ID="CompareValidator1" runat="server" ControlToValidate="TextBox1" Display="Dynamic" ErrorMessage="Invalid Date!" Operator="DataTypeCheck" Type="Date"></asp:CompareValidator>

Hi,

Thanks for the reply. I used the CompareValidator and now the date is invalid all the time.

The format of my date is DD-MON-YYYY.

I was hoping not to have to edit the date field at all.

Instead of TextBox, use Label which you fill with a date from your popup calendar and than in DetailsView1_ItemUpdating event use this code:

protected void DetailsView1_ItemUpdating(object sender, DetailsViewUpdateEventArgs e)
    {
        Label lbl = (Label)DetailsView1.FindControl("Label1");
        e.NewValues["ProductName"] = lbl.Text;
    }

Hi,

Label is no good because it does not generate an html textbox.

The javascript has no place to put the selected date

self.opener.document.Form1.DetailsViewEvent$EventDate is null or not an object

sorry,

This thread describes a similar problem.

The TextBox can easily be deactivated by including onkeydown="return false;"

This prevents the user from entering anything into the textbox
