GenericDropdown with TreeView Control with Validation control

[Administrator]

Hi,

I would like to use RequiredFieldValidator with the GenericDropDown with TreeView Combo control.
In the RequiredFieldValidator, under the "control To Validate" property, I don't see my the GenericDropDown with TreeView Combo control name. I am dynamically filling the control tree.

Any help would be great!!

Thanks!!

Hi Rekha,

We are not clear in your query. We thought you are trying to validate the GenericDropDown using RequiredFieldValidator. If so, You cannot use all Web Form controls(not only Syncfusion controls) in conjunction with the validator controls other than textbox control. If this not a case could please update us with more information. It will helps us further investigation.

Let us know if you have any other queries.

Thanks for using Sycnfusion products.

Hi Gokulkumar,

I have used RequiredFieldValidator with the dropdownlist control in ASP.NET pages and it works. I was wondering why the GenericDropDown control value is not shown under the controlToValidate property?

Is there anyother way to validate if not use javascript?

Thanks!

Hi Monica,

The RequiredField Validator functionality is not applicable to the 'GenericDropDown' control at present. I have filed a feature request which enables the 'RequiredField Validation' for the GenericDropDown control.

Meanwhile the below link is a work around sample, in which the 'RequiredField Validation' functionality is achieved through the javascript codings.

Please try running the sample and let me know if this helps you.
