Hello,
I'm wondering if Telerik team plan to make the validation (Ex.: RequiredFieldValidator) with the value selected in the RadComboBox instead of the selected text like actually?
For sure I can use a CustomValidator but why use a CustomValidator when a RequiredFieldValidator can normally easily do the job.
Thanks for your help
Cedric

Hi Cedric,
Welcome to Telerik Community!
Indeed - this would have been the more logical approach, especially given that the standard <asp:dropdownlist> control validates against Value as well. However, we had some technical difficulties trying to validate against Value.
The combobox is a composite control, its input area being essentially a <input type"text" ...> DOM element. The .value property of this DOM element corresponds to the actual text being written inside the textbox. This is not the case with <asp:dropdownlist> which corresponds to DOM <select> element and a number of <option> elements of ListItems which have different value / text properties.
Even the validation is performed against the Text property, you can still use the RequiredFieldValidator.
Attached, you can find a page with two comboboxes. One of them is validated with CustomValidator and the other with RequiredFieldValidator.
Please download it and give it a try.
Sincerely yours,
