CallByName multiple property levels?

[Graff]

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

I have

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

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

[<ABX]

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.
