Hi,

This is more like the same as what I have on my code. Will the url be a string?or a URI object?also does the filePath require a filename?

Hi,

I tried this code:

Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
grdExcel.AllowPaging = false;
grdExcel.DataBind();
grdExcel.RenderControl(hw);
Response.Write(sw.ToString());
Response.End();

and also I followed the instruction about extension hardening. see this article: http://blogs.msdn.com/b/vsofficedeveloper/archive/2008/03/11/excel-2007-extension-warning.aspx

..now the files can open and it does not give me an error..the problem now is that it did not populate the rows and column that are in the gridview, it's basically just a blank worksheet

Hi,

I am concerned that this solution might not work for multithreading since it does the saving on the server size and not client..(pls correct me if im wrong).

Thanks

Hi,

I followed the solution and it still gives me a corrupted file

Hi,

I still get a corrupted file

it seems that the path is recognized as a server path not a client path. I tried just putting C:\ and it saved it on the C:\ of the server not on my local machines C:\

I try to deploy it on a remote server. Yes, it runs in IIS, I also have control over it via remote desktop.

Thanks,

I do not have problem reading the contents of the excel file. My problem is using filestream to copy the excel file from a different path to another path

Just an update on my problem..i tried to replicate this on an ordinary web form and not a master content page and the javascript works..im not sure why it does not work with master content pages

i got another example from this link http://sorin.serbans.net/blog/index.php/2008/03/19/windowopen-and-passing-values-between-browser-windows/

I revised it and this is how it looked like on my code:

Parent:

function openChildWindow(tagetControlId) {

var s = "BrowseDirectory.aspx?id=" +tagetControlId;
window.open(s,'', 'width=400,height=600,status=no,toolbar=yes,menubar=no,location=no');

return false;
}

Child:

function Done() {
p = window.opener.document; //parent window
alert(window.opener);
target = p.getElementById(GetElementFromQuery(location.search.substring(1), 'id'));
alert('1 ' + target);
target.value = document.getElementById('browseTextBox').value;
alert('2 ' + target.value);
window.close();
}
function GetElementFromQuery(url, name) {
x = url.split("&"); for (i = 0; i < x.length; i++) {
if (x[i].split("=")[0] == name) {
return x[i].split("=")[1];
}
}
return "";
}

I am getting a null on target..but on the example it shows an object..

I tried the example and it worked..but it did not work on my web app..I am calling the child page from a master content page..the examples are 2 not master content pages..does it matter?

Thanks,

How do I know if the URL is from the same domain? the child window is opened by calling window.open from the parent page..and the alert does not show up

is there a way to have it go back to the client side and then proceed to server side code?

thanks,

When doing some more debugging i found out something on the the code..instead of popping up a dialog box when the code passes on the clientscript line..what it does is passes on the clientscript block, and continue until the function is done and pops up a dialog box..am I doing something wrong in the code?

Thanks,

i used ClientScriptManager.RegisterClientScriptBlock (Type typeofscript, String key, String script, true)..to initialize a javascript alert dialog box and it worked..im not sure why it does not let the confirm box pop-up..

Yes, that's why I put it on the codebehind since I need to have a dialog box that will pop-up and let the user know if they want to continue of not.

Thanks!

The line before the variable declaration of DiagResult calls the ConfirmBox() where I can assign the value of the inpHide through the javascript function. But in this case, the ConfirmBox() does not execute..but when I put the ConfirmBox() function on the onClientClick event of the button it pops-up..any idea??

thanks,

I am calling it from the class file that I added in the project, not the class file from the .aspx .. In the .cs file I do not have an option to call the ClientScript.RegisterClientScriptBlock

Hi,

Thanks, but this article only states how to call javascript from code-behind (aspx.cs) file. I am looking for a way on how to call a javascript from .cs file.

Thanks,

So i should assign a variable to catch the window.open()?

Hi,

Thanks for the tip. I was able to solve my problem, by creating a function in the Class instead of the page and have the class called by the page. The page passes the control that needs to be evaluated as parameter to the GetQuarters() function.

Thanks,

Hi,

I am not sure if I can put the function call of GetQuarter() on Page_Load since the GetQuarter() function is called on an onClick event.

Thanks,

sorry..i got it wrong it should be Default() not _default..

Hi,

I made a change on my returning function. Here is the code:

function SendValueToParent() {
var myVal = document.getElementById('_browseTextBox').value;
alert("Im here");
window.opener.document.getElementById('<%= txtRaw.ClientID %>');
window.close();
return false;

}

txtRaw is a control on the parent page.. am i doing it right?

thanks,

hi,

here is the code..I think I got the one above wrong

function SelectAndClose()
{
txtValue = document.getElementById('_browseTextBox');
if ((window.opener != null) && (window.opener && !window.opener.closed))
{
window.opener.InvokeParent(txtValue.value);
}
window.close();
return txtValue;
}

Hi,

Yes I do have an asp control: <asp:TextBox ID="_browseTextBox" runat="server">..

Hi,

I tried doing that but it gives me an error object not set to an instance. I declared a new instance for the class with the control as it's member.

Thanks,

I was wrong it did not give me the text value I need, it still give NULL value.

I was able to make the control public by declaring it public from the aspx.designer page.this got what I need, but will still try the previous approach I was thinking of

Im accessing this public function from a class, I can't access the controls from another class so I made a public class from form1 that will access the controls from form1 so that I can use it at the Class that I created.

Thanks

Hi,

It will be used by other web pages, so there are other control IDs that will used the value returned by the function..

I don't know how to get the return value from the function..I also tried to use Session in passing the value, but still it won't work.

do I need to declare 'selectedNode' as TreeNode? sorry, im quite new with asp.net c#..

thanks,

...i think i got the answer :)

varID = myListbox.SelectedItem.Value.ToString();

Thanks for the clarification..just a follow up question on this..now that I binded the data to the listbox, it now shows the Emp_name on the list box. Now, when I select the Emp_name and press the button Select, I want to store the Emp_id in a variable..but what it gives me is still the Emp_name and not the Emp_id..i have this in code:

varID = myListbox.SelectedItem.Text;

Hi,

I currently have that setup, the connection to the DB is within the (!IsPostback) bracket.btw, I have a master page and I navigate through a MenuItem, which points to different MasterPage contents.

Thanks,

so how do i count the number of rows in the gridview from a separate JS file?

its in this line Dim myChart As Excel.ChartObject = WB.Charts(1)

Thanks,
