Previous Value On Pop-Up (Window.showModalDialog()) .

Question

1.00/5 (1 vote)

See more:

I have two .aspx pages viz.
(1)Parent.aspx
(2)Child.aspx

Parent.aspx has a gridview with 'AutoGenerateSelectButton=true'.Data is binded from code behind on page load.

Child.aspx is actually a pop-up which gets opened from Parent.aspx's gridview's selected index changed event.
Below is the code to open on Gridview selected index changed

C#

ScriptManager.RegisterClientScriptBlock(this, typeof(System.Web.UI.Page), "OpenChildWindow", "ADDRESS_POP_UP();", true);

JavaScript

var retVal;
function ADDRESS_POP_UP()
 {
  retVal = window.showModalDialog("Child.aspx",'Show Popup  Window','dialogHeight=1500px;dialogWidth=1500px;resizable=no;center=yes;fullScreen=yes');
                       window.location="Parent.aspx";
            
  }

Code executes very well.The data from parent is passed to child and data is binded from parent form to child form .Then I close the child form and again click on parent forms another row of the same gridview,at that time child form is called but the previous data is not cleared.The child form is not rebinded with the new values.

why is it so?
Any idea.Kindly help.

Thanks.

did you try with child page_load?

If could not possibly be "ShowModelDilog". Please understand that right spelling is a mere politeness, and the wrong is... hope you got it.
Do you have a problem with Copy/Paste? :-)

This problem was solved by changing to the following IE8 settings
-> Internet Options -> General -> Browsing History -> Settings -> Temporary Internet Files ->'Every time I visit the web page'

You could also make sure the call to Child.aspx is always unique

JavaScript

var retVal;

function ADDRESS_POP_UP()
 {
var d=new Date();
  retVal = window.showModalDialog("Child.aspx?d=" + d,'Show Popup  Window','dialogHeight=1500px;dialogWidth=1500px;resizable=no;center=yes;fullScreen=yes');
                       window.location="Parent.aspx";

  }

Solution 4

Place the below code in the child Pageload event.

VB

Response.ExpiresAbsolute = DateTime.Now.AddDays(-1D)
Response.Expires = -1500
Response.CacheControl = "no-cache"
