    </div>

Serve Code

protected void btnCheckPatientID_Click(object sender, EventArgs e)
    {
        iframeCheckPatient.Attributes["src"] = "Check_Patient.aspx?patientID=" + txtPatientID.Text.Trim();
        btnCheckPatientID_ModalPopupExtender.Show();
    }

I have open an Ajax Modal popup on click of btnCheckPatientID. In Modal Popup load an iframe which contains Check_Patient.aspx page.All working correctly.

In Check_Patient.aspx there is Pass button. On click of button i have to return some value to parent page.

What should i do. Search on google but cant find any help

Answer 1

You can use button postbackurl property where you need to specify your parent page address and on the parent page use the following code:

let say you have a textbox on your popup, you can use the same as folows

TextBox txtnew=(TextBox)PreviousPage.FindControl("id or name of control");

and then use its value OR create a property on popup page like

public string popupdata
{
   get; set;
}
popupdata=your poppage value;

now access the same on parent page using

string str=PreviousPage.popupData.Tostring();

OR you can use cookies or session as your other options.
