Response to: dynamic textbox validation

Latest Revision
Hi,

You can use range validator. Add range validator dynamically in code behind file in combobox selection change event.

In selection change event method Add below code.

if(selected range is 1-5)
{
RangeValidator1.ControlToValidate = "TextboxId";
RangeValidator1.MaximumValue = "Give Max what you want";
RangeValidator1.MinimumValue = " Assign min what you want";
}
else if(selected range is 6-12)
{
RangeValidator1.ControlToValidate = "TextboxId";
RangeValidator1.MaximumValue = "Give Max what you want";
RangeValidator1.MinimumValue = " Assign min what you want";
}

Hope this might help you.
