Property3 and Property4 anre both public properties of the page I am on and the user control
Currently the code complaing about Property3 saying it cannot create an object of Int32 from '<%=Property3%>' and Property4 always gets set to 0 (the default)
I do not wish to use the c# code to set these values as this Plugin will be deployed with a CMS which I have no control over
How to get the parent page values from the usercontrol.I have a usercontrol in a page. On click of the usercontrols button i wanna get some values from the page after executing a method. i need those values in my usercontrol. What is the best way to get the results of the page in the usercontrol.
I've created user control named test.ascs with one textbox. Now I added this user control in my default.aspx page. How can i access that textbox value from my default.aspx page?
public DateTime fromdate { get; set; } public DateTime toDate { get; set; }
I am setting this values in my code behind. After setting the values i want to reload the usercontrol so that it fires a get method which will use these dates ...how will i reload the usercontrol
this is about ASP.NET, ViewState, UserControls and loosing the values of my properties. It is an classic question by know, I know, and even though I have searched here and on Google for a resolution to this problem, I havent succeeded. On the contrary, the more I test different things, the less I understand it seems.
On top of this I am using ext.net and their so called DirectMethod's but I dont think that has much to do with this problem. There are numerous questions I have and I hope that this text will be fairly readable and understandable =)
The UserControl
I have a UserControl, Customers.ascx, that contains some Properties. The "most" important is *_CustomerId*. The _CustomerId is set in code-behind, in ext.net's "DirectMethod" like this (code below from the Page Customers.aspx):
Senario: Masterpage with a UserControl and a child ASPX page
In the past when using this senario I've used an Interface as a way to pass a value from the UserControl (embedded in a master page) to the masterpage code behind then consume that value in the child aspx page.
My question is now that asp.net 4 have arrived is this still a good way to achieve this or is there another or perhaps better way to do it? I've read somewhere that perhaps "delegates" is perhaps another route to take.
im creating site with usercontrols. I have repeater, inside it is another repeater with usercontrol. My problem is passing BindedValue to usercontrol.Bindings works fine and binds the value i need but it cannot pass the value to usercontrol. When i type it manually it works, when i bind it, it passes null (!).I've tried get,set, functions (ondatabound, onload, oninit), accessing control from code with no luck. Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)
There are 2 UserControls UC1 and UC2, and there is one more class C. I want to share the same instance of c in both UserControls. I know that this can be possible with properties in both UC's and by registering UC2 in UC1 or vice versa. But I want the solution to be loosely coupled. Any best possible way without touching the Actual Page (which hosts UC's)? So i need some best possible way between UCs transfering C.
Here I have gridview control with checkbox for selection of one or two records. Have one button and when clicking this , i need to get the selected records values and assign this values to the textbox which is in usercontrol1.
have a webpage that has a button and 2 userControl placed inside the placeHolder with visible set to false.When run and click on the button, userControl1 will set the visible to true. Now userControl1 is visible and there is also a button inside this userControl1 and when click, will set userControl2 visible to true and hide userControl1. The code below is the code behide for the webpage the do the above task.
[Code]....
Is there a way to do so that when click on the button inside userControl1, is does not show userControl2? I want to do this way is because, the button is for submitting data to database and then will pop up userControl2. When there is an error, only a msgBox will pop up and does not show userControl2.
I've a ASP.Net page (Default.aspx) which will load UserControl (ucontrol.ascx) dynamically into an UpdatePanel. By using UpdatePanel, we believe we're able to prevent the entire page to be posted-back.
My problem is, within the UserControl, we have some form controls, such as inputs and buttons; after the UserControl is loaded, clicking on any button inside the UserControl will cause the UpdatePanel to be blanked. During the investigation, I found that, breakpoints within the Button1_Click() in the code-behind for the UserControl is never reached. Please reference to the code below, this references to [REFERENCE]1.
I have a page with an UpdatePanel with a UserControl in it. That UserControl contains a GridView with a nested UserControl that seems to disappear when the parent UserControl is rebound. I cannot for the life of me figure out why the child UserControl disappears. The code works beautifully on the first load, but any partial postback causes the "Pick" UserControl to disappear.
I have a UserControl, which contains another UserControl with Button. I want to add an event to that button in first UserControl (parent). I tried to do:
void Page_Init() { var btn = ChildControl.FindControl("SearchButton") as Button; btn.Click += new EventHandler(this.SearchButton_Click); }
I have two UserControls on a MasterPage. DataEntryUC contains several TextBoxes and DropDownList. NavSaveUC contains navigation buttons. When the user clicks on a navigation button, I will be saving the data entered into DataEntryUC from the NavSaveUC UserControl.
I have a couple of tables in my DB that contain stored procedure names, control names, control types, SqlDbTypes, etc.... that correlate with DataEntryUC.
How do I reference a text box that is on DataEntryUC from NavSaveUC?
I have been working on the following code from NavSaveUC with no luck.
Dim MyControlName = "txtFirstName" Dim MyControlType = "TextBox" Dim MyStringValue as String Dim tmpTxtControl as TextBox Dim tmpDdlControl as DropDownList Select Case MyControlType Case "TextBox" tmpTxtControl = CType(Page.FindControl(MyControlName, TextBox) MyStringValue = tmpTxtControl.Text Case "DropDownList" tmpDdlControl = CType(Page.FindControl(MyControlName, DropDownList) MyStringValue = tmpDdlControl.SelectedValue End Select
I want to register an UserControl in another UserControl but i have some errors like :
Control '4_txtCount' of type 'NumbericTextBox' must be placed inside a form tag with runat=server.
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: Control '4_txtCount' of type 'NumbericTextBox' must be placed inside a form tag with runat=server And when i add a server side from tag in my UserControl, i never get the error message.
How can i register and use an UserControl in another UserControl without adding server side form tag in UserControl?
I am getting int values from the stored procedure. But when i bind this datasource with the gridview i am seeing the values being converted into float. i am using Text='<% # Bind("Quantity") %' I wanna that to be displayed as int, with out zero'seg: let the value be 233, when i bind that its getting displayed as 233.00
I would rather specify fields in my code behind than embedding them in the .aspx page.
I also have a subtotal label control in my repeater that I would like to populate its text property by mutiplying two of the database values e.g productprice * unitprice shown in my repeater.
I need to do this in code behind, looping through the repeater. Any idea of how I can do this in C#?
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?
