you can use Attributes.Add

TextBox1.Attributes.Add("onblur","...");
 
<asp:textbox id="textbox1"
runat="server"
onblur="alert(this.value);" />

-- bruce (sqlwork.com)
 
<asp:textbox id="textbox1"
runat="server"
onblur="alert(this.value);" />

-- bruce (sqlwork.com)

hm... bruce, are you sure? onblur is a DOM event, it's not an
attribute of the TextBox server control
 
If asp.net doesn't recognize an attribute, it will just render it as it is:

<asp:textbox id="textbox1" runat="server" abc="xyz" />

will render as

<input type="text" id="textbox1" abc="xyz" />
Click to expand...

Well, this would make a warning regarding wrong attribute and when you
have treat warnings as errors turned on you will not be able to build
the project (code-behind). So, is this the best way?

You can also use <input runat="server" onblur=....
 
I am not saying it is the best way, I am saying it will work.

I personally use the Attributes collection, and I definitely like <input
runat="server" onblur=....more than <asp:textbox runat="server" onblur=....

Hi Im trying to add the onfocus event to a textbox contained in datalist. I
can add the attribute but the code just doesnt work.

I can add a texbox to a web page and in code behind add following ;

Me.TextBox1.Attributes.Add("onfocus", "this.value='';")
Me.TextBox1.Attributes.Add("onblur", "this.value='Click here';")

This works great, how can you do it with the textbox in a datalist. I can
the attribute the same by using the ItemCommand event but the javascript does
not work.

Thanks

Neil

I haven't used a DataList, but for most list-based controls there is a
"ItemCreated" event. Inside that event you can get references to template
controls using (Sender as DataList).FindByName("ControlName").
 
Yep I have used the event ItemCreated as such ;

Dim tmpTextBox As TextBox
tmpTextBox = CType(e.Item.FindControl("txtQty"), TextBox)
tmpTextBox.Attributes.Add("onfocus", "this.value='';")

Ive found out that the code works in firefox the way I want but its IE not
playing ball, so Im just trying to find out why. ? hate problems like this ,
a nice error msg would have been helpfull.
