Hi,

I need help. We are NOT using Visual Studio for different reasons that would be too long to explain.

I bought the suite of components yesterday. It does most of the thing that we want, but now, we are having a problem with the click in treeview.

We've been told to add this
private void SM1_ItemClick(object sender, EO.Web.ItemClickEventArgs e)
{
}
and we should be fine.
But we are getting
The type or namespace name 'ItemClickEventArgs' does not exist in the namespace 'EO.Web'

I've asked a couple times but the answer is for us to start using Visual Studio. It's not possible whatsoever.

Any of you have an idea how to fix it or should I just give up ?

Thanks
Real

Sounds interesting.

I went in web.config, added
<add assembly="EO.Web" />

in <assemblies>

<assemblies>
<add assembly="System.Core, Version=3.5.0.0, Culture=neutral,...
<add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral,....
<add assembly="System.Data.DataSetExtensions, Version=3.5.0.0, ....
<add assembly="System.Xml.Linq, Version=3.5.0.0, Culture=neutral,...
<add assembly="EO.Web" />
</assemblies>


At the top of my aspx I have :

<%@ Register TagPrefix="eo" Namespace="EO.Web" Assembly="EO.Web" %>

And in my aspx.cs I do a reference like I've been told :

private void TreeView1_ItemClick(object sender, EO.Web.ItemClickEventArgs e)
{
faa.Text = "it's working";
}

When I run the application, I'm always getting the same error :

Compiler Error Message: CS0234: The type or namespace name 'ItemClickEventArgs' does not exist in the namespace 'EO.Web' (are you missing an assembly reference?)

Source Error:



Line 154:
Line 155:
Line 156: private void TreeView1_ItemClick(object sender, EO.Web.ItemClickEventArgs e)
Line 157:{
Line 158: faa.Text = "it's working";




Any idea what is the problem ?

Thanks

Hi,

Sounds great. Now the program compiled BUT it looks that it's still not working. The program doesn't execute the onclick.

When I click on the treeview, it should set faa.Text to it's working. Well it doesn't.

private void TreeView1_ItemClick(object sender, EO.Web.NavigationItemEventArgs e)
{
faa.Text = "it's working";
}

Is ItemClick the right thing ?

Thanks
Real

No. No one told me about it.

I went in the documentation and here is what I found:

public bool RaisesServerEvent {get; set;}

Personnally it doesn't mean anything.

I took that code and put it in the .CS file. It did not work.

What should I do and why do we have to set this when it should already be set

Thanks
Real

I did it and it still not working

This is the treeview

<eo:TreeView runat="server" id="TreeView1" ControlSkinID="None" Width="500px" Height="325px"
RaisesServerEvent="true"
ClientSideOnItemMouseOver="on_item_mouseover"
ClientSideOnContextMenu="ShowContextMenu"
AutoSelect="ItemClick">
This is the text box
<asp:TextBox ID="faa" runat="server" MaxLength="20" Columns="20" AutoPostBack="True"/></asp:TextBox>

This is the code in the cs file

private void TreeView1_ItemClick(object sender, EO.Web.NavigationItemEventArgs e)
{
faa.Text = "it's working";
}


It looks that the click is not working. Why the faa.Text is never set to "it's working"

Thanks
Real

Still doesn't work

CS0122: 'services.TreeView1_ItemClick(object, EO.Web.NavigationItemEventArgs)' is inaccessible due to its protection level

Hi,

Try to change privated to protected. There are several ways to handle server event. One way is to use the syntax shown above; for that syntax you need to use at least protected, not private. Another way is to use delegate, for which you can use private.

We understand your goal and we agree that handling server event is a very basic task. But please understand that even so a lot of pieces still need to be put together correctly for it to work. This is how ASP.NET works and it is partially why MS makes and sell Visual Studio when you do not wish to deal with all these details. We have nothing against you not using Visual Studio, but it would be much appreciated if you can understand that all these pieces are really just MS stuff.

Thanks

We would completely disagree on that. I think we have already went a lot of extra miles to just get you to pick up many basic ASP.NET programming issues such as how to add reference, how to handle event, how to set a property, etc. We have no obligation to do any of those.

If you still think that the problem is with our objects, it will probably be easier for you go with another vendor because we see no point of helping you further when you still try to point your finger to us after all the extra help we have provided to you. We would have been out of business if our product can not do anything as simple as handling a click event. We will be more than happy to issue you a refund should you wish to do that.

If you wish to continue working with us, please isolate the problem into a test page that demonstrates the problem and we will be happy to take a look. Please see here for more details about posting test code:

Lastly, please review our product support policy:

Thanks

We agree that is not the point and we have nothing against either way. The point is you need to know general ASP.NET programming and to be able to solve those issues by yourself, with or without VS. It is not our obligations to help on such issues and it is certainly not a problem of our product when you run into any of these issues.



Glad that you agree on that. Below is a sample page. When user clicks the node you will see the Label's Text is being updated:
