Hi Acoder,

Here is code to create new country.

On line 13, it should be document.getEle mentById().

Show the code for clearSelect and populateCntry functions.

To update the dropdown list, access the element using opener.document .getElementById (). Don't use location or reload(). That would just reload the page.

Hi
Here is the code for populate contry & clearselect
Code:(AJAX)
[CODE=javascript]function populatecntry(r esponse)
{
// var con_id=document .getElementById ("dpdcontry").v alue
var xmlDoc=new ActiveXObject(" Microsoft.XMLDO M")//Create the XMLDOM object
xmlDoc.async = false
xmlDoc.loadXML( response)
var opt
var cityselem = xmlDoc.getEleme ntsByTagName("c ountries")
var cityelem = cityselem[0].getElementsByT agName("master_ country")
var opt = document.create Element("option ")
opt.setAttribut e("value",-1)
//var textnode = document.create TextNode ("Select Country")
opt.appendChild (textnode)
document.getEle mentById ("dpdcontry").a ppendChild(opt)
for (var i = 0;i<cityelem.le ngth ;i++)
{
var textnode = document.create TextNode (cityelem[i].getAttribute(" name"))
//alert(stateelem[i].getAttribute(" cstate"))
appendtoselectc ntry( document.getEle mentById ("dpdcontry"),c ityelem[i].getAttribute(" cid"),textnode )
}
}



function clearSelect(sel ect)
{
//alert(document. getElementById ("dpdcontry" ));
//alert(select);
select.options. length = 0;
}
[/CODE]

You don't need to reload anything. Just access the element from the child window:
[CODE=javascript]var dropdown = opener.document .getElementById ("dpdcontry" );[/CODE] Then reset it by setting options.length to 0. Then update the list by adding options using the response (XML). Remember that you can add an option using syntax like:[CODE=javascript]dropdown.option s[i] = new Option('text',' value');[/CODE]

Hi Acoder,

I tried with your code, Here im getting dropdown value as "Add New"
I am not getting newly added country value.
Code:<Javascrip t>
var dropdown =opener.documen t.getElementByI d("dpdcontry" );

I am closing popup window in CodeBehind of child page, and im retriving new value in html of parent page.that's why im getting "add new" only.If i pass new value in child window to parent window then i can get value but the entire window is reloading.I tried like
code:<JS>
Opener.location .reload(false)= company.aspx"+c _id"
it is showing error.Is there any other way?


Thanks,

Hi Acoder,

Any Answer to my problem........ ?


Thanks,
Aswath.

[acoder]

Why do you need the "Add New" option to open a popup window? Can you not just make the Ajax call in the parent window?

Hi Acoder,

How is it possible?After selecting "add new" in dropdown list then in ajax one property is there "Onreadystatech ange".Im using this property to create popup windw.I know only this way. Is there any other way..?


Thanks,

hi frnds

ur asking about why response.write is not working with ajax,this problem come to me too,. we cant write anything in browser throw response.write( ) because of script manager will not support.
