using dropdownlist server controls in webforms

Posted By:      Posted Date: October 15, 2010    Points: 0   Category :ASP.Net

I have created a registration webpage with password fields to enter and also some dropdownlist server controls to select from the list. When i change some items from the dropdownlist or when i check the checkbox in the webpage, the password entered in the password textbox gets cleared. How to get rid of this? I have set the autopostback property  of the checkbox and also the dropdownlist server controls to true.

Provide me the solution

Thanx in advance

Asp.net server controls in BlackBerry Browser

The article Asp.net server controls in BlackBerry Browser was added by roopeshreddy on Monday, May 24, 2010.

Hi All,Some of the asp.net server controls(.NET 2.0) like DropDownList control, LinkButton etc., has postback property. When User clicks or selects these controls, a Postback will occur. Let us consider LinkButton control, which is extension of the HyperLink

All my server-controls became unrecognized!!! like there's compilation error or web.config missing!



please help - the problem is in post subject.

I have lots of warnings with following text:

"Warning 10 Element 'HyperLink' is not a known element. This can occur if there is a compilation error in the Web site, or the web.config file is missing. C:\Users\Pavel\Documents\Visual Studio 2010\WebSites\BioWebSite\ToScientist.aspx 26 18 C:\...\BioWebSite\" 

But web.confg is there! And there's no compilation error!

Site builds just fine. And If I upload it to my hoster - it works!


But with all these errors I cant add controls to pages - VS2010 adds hyperlink without ID, and intelisens stoped to work.

Strange, but in my other project (web-application) I have no such difficuty.

Enabled="True" TargetControlID="Button1">  </asp:ConfirmButtonExtender>when i execute the above code,i observed that in status bar message as "connecting to localhost",if they are client side controls what  is the need of going to local server,why it is happening?Thanks in advance.

IE 7 with Webforms and Proxy Server

I have started having problems with our asp.net webform applications running behind a proxy since the user base have upgraded to IE7. Some postbacks seem to drop out and at times it is difficult to make controls on a page raise an event. It appears to be intermittant and I have been told there are issues around using IE7 behind a proxy with post requests. Is this the case and what are the options? Rewite in MVC? Does the issue of post requests behind a proxy remain in IE8? Any help greatly appreciated. Steven

JQuery with dynamic ASP.NET controls (DropDownList)

I am mixing JQuery with ASP.NET webforms.  Adding dynamic controls and accessing the selected values with JQuery works differently under different circumstances and I am trying to establish the difference. Why does Senario 1 work in debug mode but not without breakpoints?  What does databinding to a GridView do that adding DropDownList controls to a asp:panel does not? Is there some sort of DOM registration going on in DataBind? All senarios use the same JQuery: var ddlCollection = $("select[name$='ddlDynamicDropDown']") Senario 1: Breakpoints on each line (Success) Add DropDownList controls to a asp:panel dynamically in the PageLoad method (Does the page lifecycle matter? OnLoad method instead?). Run the code Select values and click on a button firing a JavaScript function (Break in Debug) Break in JavaScript file Access the dropdowns and their selected values successfully Senario 2:  Run the Senario 1 code without breakpoints (Fails to locate the ddlCollection) Senario 3: Use a GridView (Success) Add values to populate the DropDownList controls to a Generic List. Bind the values to a GridView control containing the DropDownList controls Run the code Select values and click on a button firing a JavaScript function Use JQuery to Access the dropdowns and their selected values successfully.  

Putting Server controls on top of each other

My problem is this...I have 2 server controls. A control that we can call 'SwapImageControl' where the user can change images via AJAX and a 'DoctorNameControl' where a user can change the dr. name via AJAX... The 'SwapImageControl' has a image control in it that will span over the entire table row... I am wanting to place the 'Doctor Name Control' over the 'SwapImageControl' so the user can still see the DoctorNameControl label. I tried using opacity on the Dr. Control in css but it looks terrible...Thanks in advance,Travis
