conditional readonly textbox in a datagrid

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:TemplateCo lumn HeaderText="Dat a Entry">
<ItemTemplate >
<img src="images/Barrow.gif" onclick="CopyTo tal(this);" title="Click here to
copy Previous Field to this text box">
<asp:TextBox CssClass="print ableTextbox" runat="server"
onchange="AddRe questerName(thi s);" Readonly='<% #
iif(Container.D ataItem("NotAll owed")=1,True,F alse) %>' id="txtDataEntr y"
Text='<% # Format(Containe r.DataItem("Dat a"),"$#,##0.00" ) %>'
onblur="this.va lue=FormatCurre ncy(this.value, 1);">
</asp:TextBox>
</ItemTemplate>
</asp:TemplateCol umn>

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

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='<%#Ch eckReadOnly(Dat aBinder.Eval(Co ntainer.DataIte m,
"NotAllowed").T oString())%>' ID="Text1" ></asp:TextBox>

in code behind ..
protected bool CheckReadOnly(s tring 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.

Hi everyone, I'm not entirely sure if this is the best way of going about it, but here's the scenario.......... I have two datagrid, each bound to a datatable which have checkbox columns. There are two buttons between the datagrids, "Add" and "Remove". They basically remove rows from one grid to the other, only those with the checkbox ticked.

Hi, I needed to make a TextBox on a DataGrid ReadOnly based on the condition of another cell on its row. I achieved this using a Custom Data Column Class "DacDGTextColLotNo" but I can't get the TextBox to display its value when you leave the TextBox. I figure that I need to use the SetColumnValueAtRow Method but I am struggling to understand how.

Hi All; I am using the HeaderAndDataAlignColumn class from Ken Tucker. I have customized it for a wider row. I reposition the DrawString method so the text is centered vertically in the row. My problem now is that on ReadOnly cells the shaded background is not at the top of the cell. I adjust the rectangle Height so that the shading does not drop into the next row.
