Can anybody help with the following dropdownlist problem in asp.net.

In the page_load event i fill the dropdownlist with some database values. i.e.,

MIDL

if (!IsPostBack)
        {
//filling the dropdownlist.
}

now i select item from dropdownlist and press delete button and i show the following messagebox to the user

XML

string script = "<script type='text/javascript'>alert(' data is successfully deleted');</script>";
                    Page page = HttpContext.Current.CurrentHandler as Page;
                    if (!(page.ClientScript.IsClientScriptBlockRegistered("alert")))
                    {

                        page.ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", script);
                    }

Just try binding the DropDownList after deleting.

DropDownList1.DataBind();

Solution 2

Yo have to call the dropdownlist bind function/method after deleting the record.

The binding code which you have written in page_load should be changed to a method/function.
Then call that method/function in the page_load and also after delete.

Here is one solution for that

U just remove that item from dropdownlist

Write following code inside btnDelte_Click Event
After Displaying Ur Message

DropdownList1.Items.Remove(DropdownList1.SelectedValue);
