create RangeValidator at Runtime [RESOLVED]

[johnweidauer]

I am dynamically creating my form because the information I want in this form is controlled by a database and therefore needs to be dynamic. I am creating a RangeValidator:

                QtyVal = New RangeValidator()
                QtyVal.ID = CStr("ValQty" & DBReader("ProdSKU"))
                QtyVal.Attributes.Add("Type","Integer")
                QtyVal.ControlToValidate = CStr(NewTxtBx.ID)
                QtyVal.MaximumValue = "30"
                QtyVal.MinimumValue = "1"
                QtyVal.Attributes.Add("runat","server")
                QtyVal.Text = "<BR>Must be between 1 and 30"
                QtyVal.Attributes.Add("display","static")

My problem is that it validates the values as a string (i.e. User enter 1-3 everything ok, 4 and up and validation dies). Any ideas?

1) Make sure the control is actually being added to the page (view the source in the browser)

2) The RangeValidator already has a type property, so you don't need to add it as an attribute, just set it in the code.

QtyVal.Type = ValidationDataType.Integer

3) The ControlToValidate property will just be the string name of the control. It will probably be the ClientID property of the textbox, since the control is being validated on the client.

QtyVal.ControlToValidate = NewTxtBx.ClientID.ToString()

4) You don't need to add the runat="server' attribute. Just make sure you add the control to the page properly.

5) You don't need to add the "display" attribute to the control, because the RangeValidator has a display property you can just set in code.

QtyVal.Display = ValidatorDisplay.Static

Ok, I have changed my code to be as shown below.

            QtyVal = New RangeValidator()
            QtyVal.ID = CStr("ValQty" & DBReader("ProdSKU"))
            QtyVal.Type = ValidationDataType.Integer
            QtyVal.ControlToValidate = NewTxtBx.ClientID.ToString()
            QtyVal.MaximumValue = 30
            QtyVal.MinimumValue = 1
            QtyVal.Display = ValidatorDisplay.Static
            QtyVal.Text = "<BR>Must be between 1 and 30"

Thank you very much for your assistance.
