dynamic textbox

[muthuraman]

Hi there,

 

I am trying to create a textbox dynamically in my code. When I try to set the backcolor of the textbox to somecolor, it doesn't happen. I find that the backcolor of the form is overriding the control's backcolor. Same is the case with forecolor. Can anyone help me?.

 

Thank You.

Could you show hte code you are using?

Just tried the following in a button click event and it worked without any problems.

 

Dim t As New TextBox
t.BackColor = Color.Beige
t.Visible = True
Me.Controls.Add(t)

Hi,

 

The following is the code I tried.

 

Dim test as TextBox

 

'The following code goes into Form Load event

test.BackColor = System.Drawing.Color.Aqua

test.Text = "Hello"

test.Left = 300

test.Top = 400

Me.Controls.Add(test)

 

This works fine if I have it in Form Load. The same code doesn't work inside a button click event.

That code wouldnt work. You need to create a new instance of the TextBox object, not just a variable of that type:

Dim test As New TextBox

Sorry about that. I created a new instance.

Cut and pasted your code into a click event handler (and created a new instance) - worked first time.

Is there any other code in the form load or paint events?

[muthuraman]

Yes, I have some other code in the form load event

Does that modify backcolor properties for the form / controls on the form? Could you post hte code here?

[muthuraman]

Oh yes, it does. I have a function call which checks if each textbox has a non-numerical value and highlights the respective fields. Then I set back the color of all the fields to the default color.

 

It works fine if I paste my code after this function call.

 

Thanks a lot 'PlausiblyDamp'... :)
