I have a windows form control which is hosted inside an Asp.Net page.
Is there a way to pass value from this control back to the Asp.Net page. I have tried using
"document.forms[0].UserControl1.publicProperty" where publicProperty is a publicly defined property in the control but it is giving undefined.
[code]....
I wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.
So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.
So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"
Is there a way to resolve this issue? may be Dictionary List?

View 3 RepliesMy Windows Form Control is working fine when hosted on Windows Form.It is also working fine on .html host if I use only a TextBox and a Button in that control. But when I add a third control i.e. WebBrowser Windows Form control then .html page is not displaying the control at all.Later I remove the WebBrowser Windows Form control to go to previous state and even then .html page is not displaying the control as it was displaying a TextBox and a Button control before.I delete browser history but no use. I am using the following line in my html page.

I need to force SSL when going to the final checkout page (for example from default.aspx to checkout.aspx).
I need to pass variables to this check out page and tried to use server.transfer(https://www.mydomain.com/checkout.aspx). I then use previous page .Fincontrol to read text box and label name to this check out page. If I only do the server.transfer("~/checkout.aspx") then my I can read all vakues of my controls from the passing default.aspx page.
But when I force https:// then I cannot read the control values from default.aspx page.
Please give me some tips on how to get control values to the https:// destination page or if you have another tips on how to do it the right way, please let me know.
I have a gridview that pops up when you click a link. It displays 5 columns.. if you click on the "select" link next to the record, i pass that rows values back to my form and submit the form again.. this works fine if i select a record that has all my form field values..
but if i pick a record that has some values that are empty it doesnt work.. after debugging im finding that for the fields that are blank on the screen, this is the value being passed " " which of course is not empty or null.. so my code doesnt know how to handle that.. i even tried to add .Trim() to the end of the gridview value and still getting that space being passed. How can i pass empty string instead of the for fields that dont have anything to pass?
This is my code i have for the SelectedIndexChanging event of the gridview

I have a page that contains a few user controls which all use an id in a querystring. I want to change this so that the page can send the id to the user control and can call a function on the user control.
Also is it possible for the user control to get the id from the page or a control on the page as its parent?

View 2 Repliesthe possible options to get the dynamic web pages. Existing application: We have windows application to desing the "Screen designer templates". The end user uses this application to make his own screen templates, save the information in xml and get the screen in run time. This works fine for windows based application. Current Problem: Its difficult to provide such screen designer application in web. I mean Drag & drop the controls in web page during the run time. So we are planning to use windows application to design the template. And during the run time user should get his own designed template on web page. We are trying to display the similar web form like as windows form with matching controls. let me know what are the options available to solve this problem.

View 7 Replies I am working towards porting a windows application to web. The windows application is quite rich w.r.t. the form controls, complex validations and user interactivity.Basic web forms are inadequate to meet these complexities. So I would like to know the best way to still have the richness on the web pages. I have some ideas and would like comments.
Use DHTML & Java Script to mimic complex controls. There are some macro controls available as part of jQueryUI that can be used and some other third party Java Script controls. I'd like suggestions if there is a recommended control library.Use RIA (preferably Silverlight) wherever rich controls are needed. I'd like to keep this as a last option because it mandates the Silverlight plug-in.What are other popular / preferred strategies?
We do have a search page for customers which returns a list of data from a table.
Once we select on an item it should redirect to another page with customerId as a querystring parameter..
Now the problem is we have to save all the customerIds and need to send them to display page..and need to select next one once they done with previous one without going to the search page again..
Example:
if they got 10 customers in the search page then we need to send all 10 ids to display page by starting display of firstone and once they select next button on display page they have to move on to the next cutomer from that list..if they reached the end of list they have to start again from the first...we need to avoid the user going to the search page for each customer every time...
I need to auto-redirect a page depending on the a ID number in the address bar. When I run this code, It is giving following exception
string temp = Request.Url.ToString();
string subTemp = temp.Substring(temp.IndexOf("ID="));
temp = subTemp.Remove(subTemp.IndexOf("&"));
subTemp = temp.Substring((temp.IndexOf("=") + 1));
Response.Redirect("http://Share1/ncr/Default.aspx?ID=" + subTemp);
