Web Forms :: Passing Values From Web Page To User Control?
Mar 10, 2010
I am exposing state_v value by using property in aspx.vb page..How can I create an instace of the page in User control to access this property...mypage.aspx
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?
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?
I have a web form that has drop down controls. These controls are data bound to a database. Now, I would like the results of the selected values to be shown on a new aspx page in a gridview or detailsview.
I have a user control which has some properties configured on it. I need to access (actually, only read) the values of those properties on the client. I have done it like this.
Code behind:
[Code]....
ASPX:
[Code]....
That works but, at the back of my mind, I'm sure I've seen a neater way of doing it, although I suspect that may have been on an Extender not a User Control. Pointers on that welcome.
Also, related to that, the User Control itself has an Id which becomes part of the name of all visual objects included within it. However, the User Control is not a DOM element in its own right (because it has no visible rendering) which [I think] means that I have to attach properties to one of the visible elements within it, and not to the control itself?
have two user controls on one aspx page. UC1 has a grid which contains a link button column which user clicks. Based on the value of clicked cell, I need to show some data into UC2.How do I pass data from UC1 to UC2? How do I invoke a function of UC2 from UC1?
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 am building a webpage and getting the values entered in textbox from the use now I want to use the values on the next page and want to display the values overthere... I'll explain in detail:
I have a form like below:
Now I want to redirect the user to another page on button click and then use the values of this textbox.
I am able to transer the single value to another page(Pop_up) using following code i wanted to pass one more value to another page how can i add to following code.
I would like to use the gridview paging feature and have built a gridview with a user control. The data source has lots of columns, so to make it easier I want to return a LIST<MyObject> and just pass <Myobject> into the user control rather than all the data elements. Not sure how I access the object of the data source to bind to the control. Assume it would be during ondatarowbound.
Also, my guess is there is a better way to do this than gridview. I'd take either solution that allows me to have easy paging and pass the complete object into the user control
I've a form containing 30+ textboxes. I'd like to save the data entered in the form texboxes in an object(session) and pass them into another page and simply display the values in a tabular form. How can i do that. Also, suggest me the best way to do it.
i am trying to develop forum page in asp.net using c#. I have listed forum threads lists as Title, Description, Posted On, Posted By like that using Listview. Now my idea is if the user clicks anyone of the title from the list the control will move to new page. there based on thread title selected from listview i would like to display the reply msgs posted for that. i am struggling lot here.
I'm dynamically loading a user control from a for loop against a objects collection, eg.
[code]....
I want to pass the following collection into the user control: oPerson.Address[i].listHistory (listHistory is a List of objects which I want to manipulate inside the usercontrol)
How can I pass this into the usercontrol so i can do this
Again, I am wondering why there is no one asking this kind of question. And may be my idea is wrong. Let's see the code:
<uc1:drilldown ID="drilldown1" runat="server" sType="F.W" rID='<%=request.querystring("r") %>' /> After it passed into my property in user control, the value is <%=request.querystring("r") %>
In VB.net .... I have GridView from which i select list of rows using check box and upon clicking the button i need to display those selected rows in a gridView of another page. and that page is a popup window?

I have a web page that contains a GridView which the user is allowed to "Edit", "Delete" and "Select" rows. What I'm trying to accomplish is when a user clicks on "Edit", they are redirected to another web page that contains a DetailsView of the record they selected from the GridView (previous page). How do I make the association?
i would like to ask about how can i open user control page when i click a button on parent page, also, can i call parent's method from user control page and then refresh parent page?
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...
