all ur validation controls have EnableClientScript = true property.. that means as soon as the text changes, the validation will fire..
and wen u`ll click on the submit button, the validation summary will be displayed.. and no page postback will occur...
so check.. EnableClientScript property..

I'm trying to save myself some time and loads of typing, and want to use a for loop to generate table rows within a DataList element.
This is what the code looks like in general:
<asp:datalist ...="">
<itemtemplate>
...
<table...>
...
<% for (int i=1; i<=10; i++) { %>
<%# DataBinder.Eval(Container.DataItem, "somefield_a_"+i.ToString())%><%# DataBinder.Eval(Container.DataItem, "somefield_b_"+i.ToString())%><%# DataBinder.Eval(Container.DataItem, "somefield_c_"+i.ToString())%><% } %>
The dots are there to make this readable, there are hundreds of fields in the data source and the template is quite large. Some of them end in _1, _2, _3 etc and rather than typing in all the rows I'd like to just specify one and let the for loop do the work for me.
I guess something like this would have been fine in ASP but it's obviously not working in .NET.
Is there any way to achieve what I'm trying to do in .NET?

I think you can get it to work, but you may need to use a page.Bind in your code behind. I haven't tried to do a for loop, but I have done if statements. So I would try a page.bind.

If I understand correctly Page.Bind is just like calling DataBind on every control.
There's no problem with the data source here, or data binding, it's all working fine.. I'd just like to have a for loop that goes through the row and replaces the last character in the field name with the one from the variable.
Rather than doing this:
<%# DataBinder.Eval(Container.DataItem, "somefield_a_1")%><%# DataBinder.Eval(Container.DataItem, "somefield_b_1")%><%# DataBinder.Eval(Container.DataItem, "somefield_c_1")%><%# DataBinder.Eval(Container.DataItem, "somefield_a_2")%><%# DataBinder.Eval(Container.DataItem, "somefield_b_2")%><%# DataBinder.Eval(Container.DataItem, "somefield_c_2")%><%# DataBinder.Eval(Container.DataItem, "somefield_a_3")%><%# DataBinder.Eval(Container.DataItem, "somefield_b_3")%><%# DataBinder.Eval(Container.DataItem, "somefield_c_3")%>etc.. you get the picture..

Actually, what I have found is without the Page.Bind the <% for loop stuff doesn't get evaluated. I guess I should say that if your code above is in a control then you can just bind the control as well.
I recently had a formview that was doing some conditional stuff with. If I didn't do the forview.databind you would see the <% if statements on the page.
So what I am saying is that Page.Bind will hopefully work for you in translating your for loop to the code above.

Use a Repeater control or a DataList control

First, you should be using stored procedures. If you can't then at least use a SqlCommand and SqlParameters.
Second, never allow unvalidated text to be inserted into your command or database.

i know its bad programming practice, and very much prone to sql injection...
but just a mini project thing.. for some hit and trial..

All the more reason to practice more correct techniques. When the deadline is near you will code what is quick and spend hours debugging and fixing afterward.

Are you trying to run an application developed in Framework 2.0? If you are, you'll have to configure your web server appropriately.

|
|
|

yes, i have installed Framework 1.1 & 2.0. Do i need to unstalled 1.1 ?
And how to configure the web server to avoid the error ?
Thanks..

No.
Open IIS manager, right click on virtual directory, go to properties - ASP.net tab and then select the appropriate version.

What makes you think it is web server configuration problem? The exception is that Sql Server can't be found?

You are quite correct...
That'll teach me for not reading the question properly... (in my defence, it's nearly quitting time and my brain has turned to fluff...)

Check your connection string first. If that is valid make sure the user can access it. If you are using intergated security you must make sure the ASPNET user account has been granted access to the SQL Server.
