Using Eval and Bind on UserControl [modified]

Hi,

I've created a UserControl with some public properties that get exposed via the form tag on the aspx page. However I can't seem to get Eval and Bind to work with any properties on the control. I keep getting a compilation error "

Server tag not well formed<code>". Heres an example:<br />
<pre><code><uc1:MyUserControl ID="MyUserControl1" runat="server" MyPoperty="<%# Eval("ItemProperty") %>" />

Does anyone know how to get this to work on a UserControl? I've tried adding the BindableAttribute(true) directive to the properties but no luck.

Cheers,
Rory

ISn't it DataBinder.Eval() ?

Yeah I keep seeing examples with that as well but I haven't bothered looking into why. Best guess is that was the .NET 1.1 way of doing it - I'm pretty sure just using Eval() or Bind() now does the same thing - I could be wrong. Either way I tried that as well and it didn't work.

It seems the same is also true of certain controls themselves, such as the Image control, you can't use any databinding expressions with that but you can with a Label control. Can someone explain what controls can have expressions and what ones can't? I can't see any obvious difference in the classes.

Just found this in our codebase...

<asp:CheckBox Runat="server" ID="cS" CssClass="Gensmalltext" Checked='<%#DataBinder.Eval(Container.DataItem, "Selected")%>' Tooltip="Mark Line for Adding" OnCheckedChanged="cS_CheckedChanged" AutoPostBack=True> </asp:CheckBox>

Try passing the Container.DataItem part and see what happens....

This link "explains" lol...

This code binds to a dataset though, rather than a custom object...are you able to bind to a dataset?

Following is the code to clear all text boxes. But It won't be clear when the textbox is "Multiline".
Please give the solution as soon as possible.

function ClearTextBoxes()
{
for (i=0;i < document.Form1.elements.length;i++)
{
if (document.Form1.elements[i].type == "text")
document.Form1.elements[i].value="";
}
}

Hi,
While rendering to HTML, multiline textbox will be considered as text area. So if you can consider the same in the condition specified, then it will work fine

The code is given below

function ClearTextBoxes()
{
for (i=0;i < document.Form1.elements.length;i++)
{
if (document.Form1.elements[i].type == "text" ||document.Form1.elements[i].type == "textarea" )
{
document.Form1.elements[i].value="";
}
}
}

hope this will work for you

you can use "textarea" in place of "text"

BTW please use same thread for the discussion it is just waste to create a new thread for the discussion of the same problem.

What do you think people here are bound to give you the solution, whoever is helping here are doing it in the free time. So asking to send the solution by marking "as soon as possible" seems to be offensive.

Just use Response.Redirect("abc.htm") on the button_click event in the aspx page.

I'd make the button plain HTML and do the redirect without bothering about a round trip.

That depends on how you want to display the page.

To display it in an existing window (usually the current), set the location property of that window. Example:

window.location = 'AnotherPage.html';

If you want to display it in a new window, use the open method. Example:

window.open('AnotherPage.html', '_blank');

You can also specify a third parameter in the method containing settings for the window, like size and position.

None. It's Javascript, and the window object is part of the DOM (document object model).

In the code. It's a string.

Hi
you can loop through all items of the listbox

<br />
 foreach (ListItem objitem in ListBox1.Items)<br />
        {<br />
            if (objitem.Selected)<br />
            {<br />
                <br />
                // assign to the string ot can put a counter to see it is all logic that you use <br />
            }<br />
        }<br />

Thanks and Regards
