  [Bindable(true)] property is not visible in Designer

  Aug 10, 2012 10:55 AM|LINK

  Hello,

  in my ascx control, I have bool property marked as [Bindable(true)], but this property is not visible in designer - see on the picture

  

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Web;
  using System.Web.UI;
  using System.Web.UI.WebControls;
  using System.ComponentModel;
  using System.ComponentModel.Design;
  
  [DefaultBindingProperty("SelectedValue")]
  public partial class Controls_LabelAnoNe : System.Web.UI.UserControl
  {
      protected void Page_Load(object sender, EventArgs e)
      {
      }
      
      [Bindable(true)]
      public bool SelectedValue
      {
          get
          {
              if (lblAnoNe.Text == "Ne")
                  return false;
              else return true;
          }
          set
          {
              lblAnoNe.Text = (value) ? "Ano" : "Ne";
          }
      }
  }

   I tried add this attributes above property, but no effect -

  [Browsable(true)]
  [Bindable(true, BindingDirection.OneWay)]
  [DefaultValue("")]
  [PersistenceMode(PersistenceMode.Attribute)]

  
  
  

  Of course that i can bind data writing manualy expression, but it is not comfortable

  <mts:LabelAnoNe ID="LabelAnoNe3" runat="server" SelectedValue='<%# Eval("Comment") %>'/>

  public bool SelectedValue      {          get          {              if (lblAnoNe.Text == "Ne")                  return false;              else return true;          }          set          {              lblAnoNe.Text = (value) ? "Ano" : "Ne";          }      } 

  Hi,

  I think you can simplify your codes like this——

  [Bindable(true)]
      public bool SelectedValue
      {
          get
          {
              return lblAnoNe.Text == "Ne";         }
          set
          {
              lblAnoNe.Text = (value) ? "Ano" : "Ne";
          }
      }
  I think I can get that in the design panel in the property panel.

  [Bindable(true)]
      public bool SelectedValue
      {
          get
          {

          set
          {
              lblAnoNe.Text = (value) ? "Ano" : "Ne";
          }
      } I think

   

  It did not help.

  Like other I tried change name of property from SelectedValue to SelVal but not effect :-(

  Hi,

  I'm thinking the following forum might be a better place for this question:

  Thanks,

  You cannot do that with user controls.  You have to make custom user controls

  You cannot do that with user controls.  You have to make custom user controls

  make ASP.NET Server Control:

  using System;
  using System.Collections.Generic;
  using System.ComponentModel;
  using System.Text;
  using System.Web;
  using System.Web.UI;
  using System.Web.UI.WebControls;
  
  namespace SrvCtrlAnoNe
  {
      [DefaultProperty("BooleanValue")]
      [ToolboxData("<{0}:ServerControl1 runat=server></{0}:ServerControl1>")]
      public class ServerControl1 : WebControl
      {
  
  
          [Bindable(true)]
          [Category("Appearance")]
          [DefaultValue("")]
          [Localizable(true)]
          public bool BooleanValue
          {
              get
              {
                  bool booleanValue = (bool)ViewState["booleanValue"];
                  return (booleanValue) ? true : false;
              }
  
              set
              {
                  ViewState["booleanValue"] = value;
              }
          }
  
          protected override void RenderContents(HtmlTextWriter output)
          {
  
              output.Write(BooleanValue?"Ano":"Ne");
          }
      }
  }

  Many thanks to all involved :-)

   The other way via this workaround is solution
