    Ext.Net Development Guidelines

    Hi,

    Can somebody tell which are the development guidelines we should know, when we're developing with Ext.Net?

    I found that several methods are not working from the code-behind.

    Example: we can't add nodes to the TreePanel from code-behind beyond the Page_Load event. A client-side event needs to be fired to modify controls from code-behind.

    The same happens to me, with the store and other controls.

    It seems like I'm not understanding how to work with Ext.Net.

    Thanks,
    Ariel

    Please post a simplified code sample demonstrating how to reproduce your scenario.

    Here's a sample built in code-behind, see

    Hope this helps.

    This might depend on how far beyond the Page_Load event you are running code. Which event are using?

    Hello Geoffrey,

    This is not related to an specific code. I found this several times.

    In this case, I've created a User Control to bind data to a TreePanel.

    I've a DataSource property and a DataBind method (in my TreePanel user control).
    The DataBind method is adding the nodes to the TreePanel root.

    If both are executed when the Page.IsPostBack = false, everything works great.

    The problem happens when the binding is done in a different instance.

    Example:
    I've a grid and a user control for editing records.
    The user control for edition, has implemented my other user control (the TreePanel user control).
    When a user clicks on the grid, I'm showing a Window with my edition user control.
    The edition user control, is binding my TreePanel user control, but nothing happens (the nodes are being added).

    If I move the code to the Page_Load of the edition user control, the Tree is rendered ok.

    That's why, I'm asking some guidelines to work with Ext.Net.

    Thanks for your help,
    Ariel

    I would like to know some general guidelines as well. Sometimes the examples page just doesn't suffice to explain some things. XD
