Updating the parent page after the child page closes...

[querry]

Hi there,

I have a problem. I am devloping a C# ASP.NET User Control (a .ascx file). I want to display a table on the user control. This table is generated on the fly. First the user control displays a Panel (<asp:Panel />) asking the user to enter the noumer of rows and columns. It also provides the user with a link button (asp:LinkButton />). When the user clicks the link button the panel disappears and a new panel is displayed with the specified number of rows and columns. This of course is handled in the "IsPostBack" part of the Page_Load. That means, I check for the condition whether the page is posted back and then create the table with the Table t = new Table();, TableRow tr = new TableRow(); and TableCell tc = new Table Cell();. Ihave two for loops (one inside the other) for costructing the table. That is, I create as many cells (columns) for every row that that the user specified.

Now, I have assigned a javascript to all of the cells like this....

tc.Attributes.Add("onclick", "javascript:window.open(add.aspx, 'Add' , 'width=500, height=500, resizable=yes'");

Now, my problem is, when this child window closes I want to use the text entered in the Text box (in the child window) to be added to the respective cell that was clicked and that too without a postback. Because if I postback the table will be created all over again causing all data to be lost.

In short,

1] I want to somehow use/pass the vatiable/value to the parent page from the child page.
2] I want to update the table cell without a postback.

I thank you all,

Regards.

When opening the window, send a reference to the child window, e.g. "add.aspx?id=td1". Then you can use this id to ref. the table cell that the iuse clicked on. One way to get this id is to use:

"add.aspx" + this.id

Then in the child window, use

window.opener.document.getElementById(id)

to refer to the table cell. Use the innerHTML property to change the table cell and you're done!

Does not appear to work.

Ok. I need a way to preserve the controls i create even if I postback. I mean, I visit the page - enter the no of row and the no of columns. Click a link button which causes to post back. I test, in the Page_Load to see whether it is a postback, if it is I generate dynamic controls that represent the table. [Table, TableCell(s), TableRow(s)]. Now after that I need to again post back but I don't want to loose the dynamically created controls. Is there a way to preserve the dynamically created controls and their values over postbacks??

Please help.

Regards.
