Hi Rajkiran

On Basis of selection of Mentor , Student List gets generated. Student List is dependent on Mentor selection

Thanks

It seems like the issue is that the AutoPostBack property is set to true for the ddlMentor DropDownList. This causes a postback to occur when the selection is changed, which results in the modal popup being closed and the page being redirected to the previous page.

To resolve this issue, you can set the AutoPostBack property of the ddlMentor DropDownList to false. This will prevent the postback from occurring and allow the user to select a student from the ddlStudent DropDownList without the modal popup being closed.

Here's the updated code:
```
    Select Mentor
```
I hope this helps!
