Does the ReportViewer control print button work inside of a modal MSIE window?

I am getting the following two error messages when using the new ReportViewer v10 control after pressing the toolbar print button. I am only seeing this error inside of a modal popup window in MSIE. The print button in a normal popup window doesn't have this error. An error occurred trying to get the current window Error: Could not complete the operation due to error 8007f305. If anyone knows of a quick fix, please let me know. Thank you. VS2010, MSIE 8, SQL Server 2008.

input button javascript does not work


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

Why does my event handler need 2 button clicks to work?


I've created a Visual WebPart in 2010 with two buttons.

One works as it should (it updates a database and puts a success string in a label) with no problems

One gets a dataset and populates some labels and textboxes (using a Page.DataBind).

With this button, I need to click it twice (not exactly a double click) - once, let it post back and then click again

If I copy the exact markup and code to a test ASPX project, it all works perfectly as it should.

I've tried both a DataSet and a DataReader - code to populate controls is like the following:


Then, after all, I follow by a Page.DataBind
Within reader.read:
lblSerialNumber.Text = myReader["Serial Number"].ToString();

Does anyone know what could cause this?

RadioButton inside GridView, How to get it work as normal

Did you tried before to drag a RadioButton control inside a Gridivew templatefield, and then you attempt to select these RadioButtons , you will notice that the behavior of RadioButton control will be changed and it will work just like the behavior of checkbox control! the user will be able to select more than one radiobutton in the grid!

Problem to group radio button across gridview rows

In general no one can easily group or make a single selection from radio button list inside gridview rows. There are a lot of way to make a single or unique selection from list. Here i want to share how i can address this problem in the most easiest way. Googling the problem most of the cases i saw the grouping in horizontal way. Thats why i tried to group the radio buttons in vertical manner. Let i have a requirement like below:

Maintain HTML Radio Button Selection Inside GridView After Postback

Long time ago I wrote an article about getting the value of the selected RadioButtons inside the GridView control. The code did not addresssed the postback issue which means that the selected radio button was cleared after the postback occurs.

A Simple and Extensible Radio Button Style GridView

The GridView is one of the significant controls in ASP.NET 2.0 and later versions. No doubt it reduces a lot of work time. However, customizing the GridView control is not an easy task. For example, it's hard to add a radio button column to the GridView. This article demonstrates the reason why a radio button column cannot act as normal and how to create a simple and extensible radio button GridView.

Editable Gridview with Textbox, CheckBox, Radio Button and DropDown List

This is an example of an editable gridview containing different ASP.NET controls. When user wants to edit values in gridview, she/he can use these controls to edit existing values in Gridview Edit Mode.

Looking for guidance: wanting to work with AJAX architecture



I'm starting a small website that will be backed by a database, and will allow a small number of users to authenticate and select an entry in the database, and then view (and optionally update) a corresponding entry (think master-detail).

I have some flexibility in how I'll do this, but I'd really like to incorperate some newer AJAX style coding, eliminating some page postbacks. I think this is a great opportunity to learn the concepts well.

I'll probably go with an ASP.NET 4.0 site. From what I've seen there are MANY ways to go about this:

-WCF Data Services to expose the data, and consume in ASP.NET

-Page methods to expose the data, separate method to update the data

-I'd rather avoid the UpdatePanel because I'm really looking for a full hands-on approach, with learning client side scripting being an objective as well.

Beyond that, it seems that one can use jQuery to build clientside templates, but also one can use the ASP.NET AJAX template engine (in ASP.NET 4.0 I believe).

A concern I have: users should only be able to work with the data exposed via these endpoints if they are logged into the website. Hopefully I can somehow reuse the ASP.NET forms authentication cookie for this purpose. 

Well, I hope I've posted enough to a

Problem with Dynamic Button


Hi friends,

I am trying to make a page inspired from http://login.qlikview.com/help.aspx

here I have made a dropdownlist and on clicking I am able to dynamically add the textboxes and radio buttons using placeholders. My problem is I am not able to use a dynamic number of submit buttons. In the page (link above) I need to make the submit button available for two choices and invisible for one.  But the option dynamicbutton is not available alike dynamicTextboxes etc. What could I do? Is there any other way I could figure out to implement this.

Thanking you in advance,


animate effect work but the render items are messed up.


Hi all,

     I have a very unique problem, humm i think. I am using a jquery effect that animate bounce effect, i have a line in my javascript pageLoad function $("#UserBrowserInfoDIV").show('bounce'); - the effects run smoothly but what it does is mess up the bolded text in the div. I have try the items inside the div without bolding and it works fine and no render problem but when bolded the text that are bolded is quite messed up, and barely readable.

Please let me know is there anything else i can do i really would like use this effect.

P.S all the effect have the same render problem, and i am using ie8 under compatibility mode.
