SP List Auto complete validation to ensure user select populated item

Question

Hello, I have a an issue validating user making sure he/she select the auto populated from the dropdown. I am populating post activities assigning values to other fields. If user not selected and just type values, its not happening. Is it possible to return to the same textbox if user not selected(and just typed). Something .Keyup or textbox change focus? Please advise.

Hi @Shri-6058 ,

You could create the form like this:

@using (Html.BeginForm("Form2", "Home", FormMethod.Post))  
{  
    <table>  
        <tr>  
            <td>Enter ID: </td>  
            <td>@Html.TextBoxFor(m => m.Id)</td>  
        </tr>  
        <tr>  
            <td>Enter Name: </td>  
            <td>@Html.TextBoxFor(m => m.EmpName)</td>  
        </tr>  
        <tr>  
            <td colspan="2"><input type="submit" value="Submit Form" /></td>  
        </tr>  
    </table>  
}  

Then add the js for validation when submit the form:

Hi @Shri-6058 ,

You could use the PreSaveAction() function to complete the validation. https://social.technet.microsoft.com/wiki/contents/articles/38255.sharepoint-2013-use-of-presaveaction-function-on-list-forms.aspx

Below is my demo code:

Thank you very much.
I should have clarified more. Currently I have an existing mvc application auto complete(I plan to integrate directly in SP list in the next release.). I must include this validation on application form submit action I believe. I am referring mvc application backend database as SP list once form is submited.
