To expand on something Mark Nischalke asked some time ago to which you never replied, what is start, what is end? Are they string's, are they datetime's, what are there values at runtime?

                  </div>

Using the DropDownList Helper

The DropDownList helper renders a drop-down list. In its simplest form, DropDownList takes one parameter, the name of the ViewData key whose value is of type SelectList and that contains the option values for the drop-down list. The MVC framework uses the ModelState property of ViewData to determine the selected value. If the ModelState property is empty, the framework looks for an item whose Selected property is set.

The following example shows markup for the DropDownList helper method.

<%= Html.DropDownList("pets") %>

The following code is a part of an Index action method in which values are added to a List object. The List object is passed to an instance of SelectList, which is then added to the ViewData object.

List<string> petList = <code>new List<string>()</code>;
petList.Add("Dog");
petList.Add("Cat");
petList.Add("Hamster");
petList.Add("Parrot");
petList.Add("Gold fish");
petList.Add("Mountain lion");
petList.Add("Elephant");

ViewData["Pets"] = new SelectList(petList);

Note:**Both the DropDownList and ListBox helpers accept either a SelectList or MultiSelectList object.

Hi,

I just like to know that can we change the way Asp.Net render the controls. Like RadioButtonGroup Gets converted in Tables and cells and radiobuttons of HTML. Can I edit the controls so that it render to Div instead of table. There are lot of controls like GridView which create lot of problems in layouting.

Thanks & Best Regards

You can subclass the control and override its Render method.

Because you are passing id as string. Use client id directly in javascript as:

ob_em_SelectItem('<%= txtItemID.ClientID %>');
window.frames['tabIframe'].location.replace("../page/" + '<%= txtItemID.ClientID %>' + ".aspx?itemID=" + itemID + "&tkID=" + tkID + "");

I am no expert in mobile websites but I imagine it's the same principle involved as with any website: you can (just) use a javascript call to open the client's "Print" dialog - after that it's up to them. Unlike a windows applciation, you cannot access their printers directly.

Can't see coded web performance test in VS 2010

I've been baning my head against the wall for the better part of a day on this issue. I cannot run my coded web performance test.

I'm using VS 2010 Ultimate.

I can do the steps below with no problem using other solutions (even by creating a new solution!) but not with one particular solution.

Here's what I've done:

1) Added a web performance test project to my solution
2) recorded a few mouse clicks in the open browser window
3) ran (repeatedly) the resultant web performance test. Works great!
4) Clicked the Generate Code button in the web test viewer window, which does create a .cs test
5) Chose Test-> Run -> All Tests in Solution. Only the original web performance test shows up in the Test Results window

I want/need the .cs test to compile because I need the .dll for use with a test plan from within Test Manager.

ANY help would be GREATLY appreiciated. Thank you.

FINALLY! OK, here's what I did to resolve the issue:

1) From the Build menu I chose to Build my test project. Building/Rebuilding the solution did NOT do the trick. I had to explicitly choose my test project name from the Build menu.
2) Then I selected Test ->Windows -> Test View. This showed my web performance AND coded tests.

Hope this helps others who have this issue!

Viewstate Error

Hi,

I have form with 3 tabs,
i each one i have a grid.

My problem is - sometimes i'm getting this error when i'm pressing the EDIT button.

Failed to load viewstate.  The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.  For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

At the first time nothing happens,
but at the second click i'm getting the above error

Can someone please please help me?

Thanks;
Tamir

Can you add the code behind, if you are adding a control dynamically (something like Controls.Add(myControl);), not doing this at postback is the most likely cause of your error (as the exception states).

This is considered rude. See the FAQs and guidance stickies at the top of the forum.
I've told you what the problem probably is (dynamically added controls), and asked for the code. I am 80% certain you are adding a control in code-behind that is being accessed in postback before it is getting re-added, but without the code it is impossible to tell.
