How To Reference TextBox In One UserControl From Another UserControl
Jan 19, 2011
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 have a .ascx file residing in another page which has a button on it. On click I run a select statement that accesses the textbox for a value.
However, it keeps returning a Null Exception Error. I am trying access the textbox and its text through
[Code]....
I also tried -[Code]....

But none of them work. Please can someone advise me how I find the textbox and then access its text?I have looked round the forums / google and cant find a way of doing this!
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.
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.
I have some usercontrol which gets loaded dynamicaly. I know how to add these usercontrols dynamically. The problem is, which usercontrol are to be added is decided only at runtime. So I cannot use <%@ register %> or <%@ Reference %> on the '.aspx' page. How to access the usercontrols without using these directives?
I have a page which holds a custom webcontrol and a usercontrol. I need to reference of webcontrol in usercontrol class. So, I make the declaration of webcontrol as public in page class. But, when I do "this.Page.", I don't see the webcontrol listed in list provided by intellisense. Most probably, I am missing something.

I am developing a usercontrol, in this case a toolbar. Some of the buttons on the toolbar will interact with other objects on the page which are not part of the toolbar. (In this case a map) So the toolbar code behind wants to say something like this:
[code]....
My problem is that MyMap does not exist in the design environment of the usercontrol and therefore produces an error when it is referenced. So my question is, How is this typically handled? Can the usercontrol reference another control that does not exist within itself?
Environment : Vista,VS-2005I have converted my user controls into DLL.(This is ajax enabled Website).[URL]In another project i have added this reference , register the dll and use the Usercontrol.It is working fine.Question1 : How to add this dll into toolBox?....Question2 : How to Rename this dll?....(This is ajax enabled Website-I have added webusercontrol in this site-After publish th site i got this dll.)

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); }
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 have created a usercontrol that get some input from the user in the textbox. now i want to get that value in my page containing the same user control.
I have a usercontrol which contains a textbox. I now want to add variable to that user control, lets call it Text, which will populate the textbox with the value passed in. I thought this could be done in the "set" of the variable in the code behind of the user control.
public string Text { get {} set { txtBox.Text = value; } }
txtBox is the ID of the textbox within the usercontrol. Does anyone know how this can be done?
Edit The problem I suspect is that I am setting the text value in the Page_Load of the page hosting the user control. Where should I be setting this value?
I can't seem to find a textbox using FindControl. The textbox is located inside an asp:Table, asp:Table is inside a UserControl and I load the usercontrol into the parent page.
I have a webUserControl that is nested inside of another dynamically loaded usercontrol. The nested user control (harddrive) can have multiple iterations, see below for hierarchy When a postback occurs the value in the dropdownlist inside of the nested userControl is saved, but the data in the textboxes is lost. any ideas?
Hierarchy: insert.aspx [^--loads] asset.ascx [^--- loads] harddrive.ascx -- there can be multiple instances of this control inside of the asset.ascx user control
