what is custom control in asp.net?

Greetings - I was referred here by MSDN forums hope this is the right place -  

I have a custom control (:WebControl) that renders web.sitemap in a specific way. While it runs error free and produces the expected result, at Design-Time it complains

Error Creating Control - MyControl  The provider 'AspNetXmlSiteMapProvider' specified for the defaultProvider does not exist in the providers collection.

I have discovered that the error is cause by this line of code:

string div = string.Format("<div class='{0}' id='{1}'>{2}</div>", this.CssClass, this.ID.ToString(), EnumerateNodesRecursive(SiteMap.RootNode, level));

or more specifically, by the reference to SiteMap.RootNode - I am not clear what is missing thoough because I have configured the SiteMapProvider in web.config as this:

<siteMap>
      <providers>
        <clear/>
        <add name="AspNetXmlSiteMapProvider" 
             type="System.Web.XmlSiteMapProvider, System.Web, Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" 
             siteMapFile="web.sitemap" 
             securityTrimmingEnabled="true"/>
      </providers>
    </s

Hi,

I want to use an image inside a Custom Web server control ! 

Do I need to use Web.resources ? if so , how to do ?

I have created a server control consisting of a TextArea and a div under it.  My goal is to create my own asp:TextArea type control.  the div is for a Character count of the text area and seems to work ok but i added a CharacterCountVisible property to the control that is always returning true.  See Proptery definition below

<Bindable(False), Category("Appearance"), DefaultValue("True"), Localizable(True)> Property CharacterCountVisible() As Boolean
    Get
        Return _CountBoxVisible
    End Get
    Set(ByVal value As Boolean)
        _CountBoxVisible = value
    End Set
End Property

Note the _CountBoxVisible variable is define inside the class as :

Dim _CountBoxVisible as Boolean = True

What I am trying to do is give the user/coder the option to show/utilize the char count feature.  Can make it disappear with textarea1.CharacterCountVisible = False but setting it to true will not make it display.

What am i missing

Thanks

Hi

I have created a custom control from scratch and it works fine as in you can build the project that uses it and it works fine at runtime. Problem is when you go to design view the control shows an error in the place of where the control should be rendered.

Error: '<SomeValue>' Could not be set to '<SomeProperty>'

This shows up on all my custom set properties. These properties are created as basic as possible. I can give the properties values in Source view and run the app just fine. I can even add a Onclick event. If I don't set any custom properties the control will render fine in Design view. It's only when I set a value to a custom property.

Property Code Example:

public string Text
        {
            get
            {
                string ret = "";
                object obj = ViewState["Text"];
                if (obj != null)
                {
                    ret = obj.ToString();
                }
                return ret;
            }
            set
            {
                ViewState["Text"] = value;
            }
        }

I've even removed the Category and Description tags with no difference.

I don't know if what I said makes sens, but I hope it

The wwDataBinder control addresses simple control data binding--binding simple form controls like textboxes, checkboxes, and the selected values of list controls to individual data or object values.

In ASP. NET 2. 0, the GridView and DetailsView controls are designed to work together. They don't merely provide complementary services, they also share a number of helper classes and components. The output of the GridView control consists of a sequence of rows, each with a fixed number of columns.

hi,

I have a requirement to use the MOSS 2007 Calendar Control - month view is to apply a custom css to have a look and feel as per our requirements.

We tried applying the custom css to the MOSS 2007 calendar control - month view, it does take the custom css and applies it, but when i click on any date and come back to the calendar control, it changes the CSS of the MOSS calendar control back to the default one.

Let me know if anyone has any suggestion on  how to customize the calendar control for css for our intranet application.

Your response would be highly appreciated.

regards

Hi all,

 

my goal is to create a custom field control based on a custom field, to be part of a custom content type which derives from a publishing page. Also I want the custom field control to be part of a custom page layout which is associated with my custom content type.

 

I followed the steps from Patrick Tisseghems book 'Inside MOSS2007', which includes the following instructions:

 

• Create and implement the following classes: CustomField, CustomFieldValue, CustomFieldControl. Sign them and deploy the assembly to the GAC.
• Create a User Control Custom.ascx. Copy it to Controltemplates directory.
• Create fldtypes_custom.xml and copy to 12\TEMPLATE\XML
• Add <SafeControl /> entry to web.config
• IISRESET

I did of all the above plus I created a page layout in SharePoint Designer which contains an instance of my CustomFieldControl.

 

When I create an instance of CustomPage (derived content type from Publishing Page, with extra field of type CustomField) with my custom page layout and add it to the Pages library of my Publishing site, everything seems to go fine. When i edit properties of the page with /Pages/Forms/EditForm.aspx I can even edit the custom field value trough the interface using mu custom field control! Everything seems to work perfectly!

 

But... this

Hello everyone -- first time poster and relative newcomer to the boards.  This bug I'm tackling has me at my wits' end and it's come time to turn to the masses!  If this is posted in the wrong forum and/or has already been addressed, I apologize.  However, I've done thorough searches and haven't come across anything akin to what I'm facing.

I'm working with a website that has a set of custom controls, all descending from a base class.  These controls take DataSets returned from web services and renders custom html via overriding the Render method.  Everything works fine on my local box and my coworker's box (both xp machines running iis 5).  However, on our server (windows server 2003, 64-bit, iis 6), the html rendered by the browser appears corrupt, with garbage replacing individual characters, as follows:
