conditional readonly textbox in a datagrid

[Guest]

I am having a hard time with this one, and I thought it would be easy.

I have a datagrid in which I have textboxs for users to enter data. One of
the fields in the database behind the datagrid tells me if the textbox is
readonly or not. I am having a hard time setting the readonly property of the
textbox with a conditional if statement (IIF).

Here is the coding;
<asp:TemplateColumn HeaderText="Data Entry">
<ItemTemplate>
<img src="images/Barrow.gif" onclick="CopyTotal(this);" title="Click here to
copy Previous Field to this text box">
<asp:TextBox CssClass="printableTextbox" runat="server"
onchange="AddRequesterName(this);" Readonly='<% #
iif(Container.DataItem("NotAllowed")=1,True,False) %>' id="txtDataEntry"
Text='<% # Format(Container.DataItem("Data"),"$#,##0.00") %>'
onblur="this.value=FormatCurrency(this.value,1);">
</asp:TextBox>
</ItemTemplate>
</asp:TemplateColumn>

What am I doing wrong with the readonly? If I look at the source, it isn't
being produced within the page.

Thank you,

There is nothing wrong with the way you used IIF. You can check the outcome
on this link: http://www.societopia.net/samples/dataGrid_5.aspx

probably the IIF statement always returns false... you may want to give it a
try changing it to a function similar to below.. this will help debugging the
condition..

<asp:TextBox ReadOnly='<%#CheckReadOnly(DataBinder.Eval(Container.DataItem,
"NotAllowed").ToString())%>' ID="Text1" ></asp:TextBox>

in code behind ..
protected bool CheckReadOnly(string val)
{
if(val == "1")
return(true);
else
return(false);

}

Yes, I just had to step through it to see what the data was sending back. i
had the field defined as bit, and because so it was already true or false. I
just needed to read the field... no iif, or anything else.

Thanks.
