• Re: Server Controls/User Controls best practices

  [quote user="xavierx"] Does that sound like a good method? Ideally I'm just trying to have to so that if i make changes/updates, I open this control solution, modify what i need, recompile, and since all the projects will reference the assembly in a central location, I change it once, it changes for all! [/quote] Is my understanding correct that you'd like to put all your controls in one assembly and put the built assembly in a share folder that other machines can access to add

  Hi, I'm unable to reproduce this issue. My test code is like below. Could you please test it to see if you can get _Query in Page_Load? ascx.cs: public partial class WebUserControl1 : System.Web.UI.UserControl { protected void Page_Load(object sender, EventArgs e) { // I can get the value of _Query here } public string Query { get { return _Query; } set { _Query = value; } } string _Query; } aspx: < uc1 : WebUserControl1 Query ="anything" ID ="WebUserControl11" runat ="server"

• Re: PersistenceMode.InnerDefaultProperty issue

  Hi, To achieve this effect we need to let the collection class inherit from IList. See below sample: [ParseChildren(true, "MyItems")] public class MyCustomDropDownList : DropDownList { [DefaultValue((string) null), PersistenceMode(PersistenceMode.InnerDefaultProperty)] public MyListItemCollection MyItems { get;set; } [DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)] public override ListItemCollection Items { get { return base.Items; } } } public sealed class MyListItemCollection

• Re: Server Controls/User Controls best practices

  Hmm.. Looks like your question is regarding revision control instead of custom control of ASP.NET. Please refer to the following documentation to choose a software to do so (Try Team Foundation Server of Microsoft if you like): http://en.wikipedia.org/wiki/Comparison_of_revision_control_software

• Re: Can't render the URL of a image defined in separate CSS file while embedding the CSS file as a resource

  Hi, Yes RegisterClientScriptInclude is used to register JavaScript files. By Page.ClientScript.GetWebResourceUrl method you can get URL of any resources. Then you can output the URL to HTML where you need. For instance: string styleSheet="Get URL by Page.ClientScript.GetWebResourceUrl"; HtmlHead header = Page.Header; HtmlLink link = new HtmlLink(); link.Href = styleSheet; link.Attributes.Add("type", "text/css"); link.Attributes.Add("rel", "stylesheet"

• Re: Custom control : getting Rowcount 0 on button event of the control.

  Hi, You cannot get rows if they are not populated yet. In general we can get all populated controls in PreRender event. You can add your code logic there.
