I understand that your code behind is VB.NET [C:\CRFF\Default.aspx.vb].
As far as I know there is no ternary operator i.e. [expr?expr:expr], available in VB.
|
|
|
|

Actually i do have VB.net code behind ,but for the purpose of instant DB
updating i've used JAVASCRIPT the sript is below, hope that would clarify
function updateSent(bSent, iRowIndex) {
var oRecord = new Object();
oRecord.OrderID = grid1.Rows[iRowIndex].Cells[0].Value;
oRecord.ShipName = grid1.Rows[iRowIndex].Cells[1].Value;
oRecord.ShipCity = grid1.Rows[iRowIndex].Cells[2].Value;
oRecord.ShipPostalCode = grid1.Rows[iRowIndex].Cells[3].Value;
oRecord.ShipCountry = grid1.Rows[iRowIndex].Cells[4].Value;
oRecord.Sent = bSent;
grid1.executeUpdate(oRecord);
}

Based on your question I understood that we are talking about a compilation error and my comment was about the checkbox definition statement
<input type="checkbox" önclick="updateSent(this.checked, <%# Container.PageRecordIndex %>)" <%# Container.Value == "True" ? "checked='checked'" : "" %> />
You are using a server evaluation to set the checked status using the ternary operator in the below line.
<%# Container.Value == "True" ? "checked='checked'" : "" %>
I guess this is where the error is, using ternary operator in a server evaluation where the code behind is VB.NET

|

I guess you are right ,cuz when i removed the[evaluation] the page loaded succesfuly , now do i have to give up the whole idea of changing the DB instantly via some JavaScript code?
|
|
|
|
|
Did you try using the IFF function to evaluate the checked status?
|
|
|
|
|
i tried but i got:
BC30451: Name 'IFF' is not declared.
i tried : Checked="<%# IF((Container.Value = "True"), true, false)%>" />
i got the old error : BC30201: Expression expected.
|
|
|
|
|
Try the following:
<asp:CheckBox ID="chkBox" runat="server" önclick="updateSent(this.checked, <%# Container.PageRecordIndex %>)" Checked='<%# Container.Value == "True" ? "true" : "false" %>' />
Hope that this will work.
|
|
|
|
|
thnx for yr swift response, but it doesnt work
|
|
|
|
|
Why din't I think of this before?
Ok try this!
<input type="checkbox" onclick="updateSent(this.checked, <%# Container.PageRecordIndex %>)" Checked="<%# IFF((Container.Value = "True"), true, false)%>" />
|
|
|
|
|
Thnx Sir,i tried but i got:
BC30451: Name 'IFF' is not declared.
i tried : Checked="<%# IF((Container.Value = "True"), true, false)%>" />

Well, we can either spend the rest of the day guessing, or you could tell us the FULL error message, including any inner exceptions. I suspect the latter will help us to help you rather quicker.
