CallByName multiple property levels?

I want to add attributes to 24 textboxes but am not sure how to go about it.

I have

Code:

---

for i = 1 to 24
    CallByName("textbox"+i,"attributes.add",CallType.Method,"'onclick','CheckTxtBox(this)'")
next i

---

And it throws up on this saying

Exception Details: System.MissingMemberException: Public member 'Attributes.Add' on type 'String' not found.

[MissingMemberException: Public member 'Attributes.Add' on type 'String' not found.]
Microsoft.VisualBasic.CompilerServices.LateBinding.InternalLateCall(Object o, Type objType, String name, Object[] args, String[] paramnames, Boolean[] CopyBack, Boolean IgnoreReturn) +883
Microsoft.VisualBasic.Interaction.CallByName(Object ObjectRef, String ProcName, CallType UseCallType, Object[] Args) +48
imac.WebForm1.Page_Load(Object sender, EventArgs e) in C:\Documents and Settings\Jared\VSWebCache\index.aspx.vb:109
System.Web.UI.Control.OnLoad(EventArgs e) +67
System.Web.UI.Control.LoadRecursive() +35
System.Web.UI.Page.ProcessRequestMain() +731

I'm pretty sure it doesn't want me putting in more than just attributes but I need to access the add.... Help would be appriciated.

Hi,

I take it you have used

Inherits System.Attribute

??

mmmm not sure......

I guess I should mention this is a ASP.NET project with VB.NET code behind and I probably should have posted this on the ASP forum....


Basically I have a webform with 24 textboxes (for simplicity sake called TextBox1 to 24)

I'm trying to add some javascript functions that are triggered by the onclick and onkeyup events. Right now I have

[Highlight=VB]Textbox1.Attributes.Add("OnClick","SetActive(this)")
TextBox2.Attributes.Add("OnClick","SetActive(this)")
.
.
.
TextBox24.Attributes.Add("OnClick","SetActive(this)")

TextBox1.Attributes.Add("OnKeyUp","CheckMsg(this)")
TextBox2.Attributes.Add("OnKeyUp","CheckMsg(this)")
.
.
.
TextBox24.Attributes.Add("OnKeyUp","CheckMsg(this)")[/vbode]

I'd like to just have

VB Code:

For i = 1 to 24
   TextBox+i.Attributes.Add("OnClick","SetActive(this)")
   TextBox+i.Attributes.Add("OnKeyUp","CheckMsg(this)")
next

Only way I know of accomplishing that is using the CallByName function but I'm not quite sure how to use it when you have multiple levels to the method you're trying to invoke

VB Code:

For Each ctrl As Control In Page.Controls
            If TypeOf (ctrl) Is TextBox Then
                Dim tb As TextBox = CType(ctrl, TextBox)
 
                tb.Attributes.Add("'onclick'", "'CheckTxtBox(this)'")
            End If
        Next

Note: this will do every textbox on the form, you will have to setup an if statement if you want to limit what textboxes get new attributes.
