input button javascript does not work

Posted By:      Posted Date: October 19, 2010    Points: 0   Category :ASP.Net

Hi All,

I'm inserting panels within a table, each panel has an increment and decrement input button that uses javascript to update a textbox value within the panel.

The buttons stopped working when I adjusted the table to have multiple columns. 

Here's the code:

        private void OrderDriver()
            //Get vendor items
            MyItemList = new List<Item>();
            MyItemList = Populate();
            //Display vendor items
            Table tbl = new Table();
            int rowcount = getrowcount(MyItemList.Count);
            int colcount = 2;
            for (int i = 0; i < rowcount; i++)

                TableRow row = new TableRow();

                for (int j = 0; j < colcount; j++)

                    TableCell cell = new TableCell();

                    Panel Pnl = new Panel();
                    Pnl.ID = "Pnl" + i.ToString();
                    Pnl.Visible = true;
                    Pnl.BorderWidth = 4;
                    Pnl.BackColor = System.Drawing.ColorTranslator.FromHtml("#CC3333");
                    Pnl.Width = 500;

                    TextBox txtbx = new TextBox();
                    txtbx.ID = "txt" + i.ToString

How do I set CausesValidation=false on a button that was created with Javascript?

I have a button on an ASP.NET page, and that button is (and needs to be) created via Javascript. The problem is, there are some validators on the page, and pressing the button is causing them to fire, and I don't want that to happen in this particular case. I am not sure what CausesValidation=false actually does on the page, but I was hoping to re-create it somehow.I have been trying to locate the button by using a FindControl() statement in code-behind, but that doesn't seem to be working. If it did, I could just set the CausesValidation there...Any thoughts?

Viewstate issue when calling button click event from Javascript

I have a javascript that asks a confirmation on search click. If the user has made some changes to the data in grid (gridview) on click of Search, a confirmation is asked to Save or Continue Search. If Yes, Save the records by invoking Save click from javascript. If No, Search click is invoked. While Search click happens correctly, Save click results in an error which reads like this..  "Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. " I know the Viewstate is what causing the problem, where the control is not loaded but script is trying to invoke it's click event. Any help is appreciated. At the end of the day, all i need is to invoke Save click from javascript.   -- Viswanth VG  

Javascript doesn't work on IE Mobile 6.12 ?

Hi, I wrote a simple asp.net page with few controls and a function in Javascript that make input validation. The javascript function is called on button click event. I use Windows Mobile 6 Classic emulator, and the javascript doesn't work at all.  I saw few posts on this forum saying that IE mobile works just with jscript and doesn't work with javascript. Is it correct ? Is that mean I have to change my javascript code to jscript code ? I always thought they are the same. Is there newer versions of ie mobile that works with javascript ?
