C# - Passing In A Value To A Usercontrol Through A Foreach Loop?
Dec 21, 2010in my asp.net mark up I have a foreach loop that iterates through a simple list. In this foreach loop I am adding a new user control and attempting to pass in the value from the loop. However, this value just wont budge and get inside that damn control!
<%foreach (userInfo i in this.items)
{ %>
<uc1:ItemControl ID="ItemControl" runat="server" UserID='<%#Eval("userID") %>'/>
<%} %>
userID is a public property in the control, when it goes to set, the value is just literally :
<%#Eval("userID") %>. I've tried #Bind and =Value but nothing seems to work.

View 1 RepliesUpdatePanel Dynamically Loaded Web UserControl Will Disappear After Clicking Any Button Inside The UserControl?
Mar 17, 2011I'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.

AJAX :: Nested UserControl With UserControl Disappears On Partial Postback
Jan 28, 2011I 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.

Ive read and tried to do all the google solutions but with no luck. (even with creating usercontrol inheritance)

Sep 27, 2010There 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.

Any best possible way without touching the Actual Page (which hosts UC's)? So i need some best possible way between UCs transfering C.

C# - Loop Through All Controls On Webpage
Nov 23, 2010I need to loop through all the controls in my asp.net webpage and do something to the control. In one instance I'm making a giant string out of the page and emailing it to myself, and in another case I'm saving everything to a cookie. The problem is masterpages and items with collections of controls inside them. I want to be able to pass in a Page to the method, then have that method be generic enough to loop through all controls in the inner-most content page and work with them. I've tried doing this with recursion, but my recursion is incomplete. I want to pass a Page object into a method, and have that method loop through all controls in the innermost content page. How can I achieve this?
private static String controlToString(Control control)
{
StringBuilder result = new StringBuilder();
String controlID = String.Empty;
Type type = null;
foreach (Control c in control.Controls)
{
try
{
controlID = c.ID.ToString();
if (c is IEditableTextControl)
{
result.Append(controlID + ": " + ((IEditableTextControl)c).Text);
result.Append("<br />");
}
else if (c is ICheckBoxControl)
{
result.Append(controlID + ": " + ((ICheckBoxControl)c).Checked);
result.Append("<br />");
}
else if (c is ListControl)
{
result.Append(controlID + ": " + ((ListControl)c).SelectedValue);
result.Append("<br />");
}
else if (c.HasControls())
{
result.Append(controlToString(c));
}
//result.Append("<br />");
}

return result.ToString();

Web Forms :: Calling Other UserControl From UserControl?
Jul 24, 2010have 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.
How To Reference TextBox In One UserControl From Another UserControl
Jan 19, 2011I 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
Custom Server Controls :: Rendering Controls Via Loop Inside Render
Nov 11, 2010I am creatin a server control where some controls are being rendered inside `protected override void Render(HtmlTextWriter writer)`
writer.AddAttribute(HtmlTextWriterAttribute.Type, "button");
writer.AddAttribute(HtmlTextWriterAttribute.Id, this.UniqueID + "butto_Foo1");
writer.AddAttribute(HtmlTextWriterAttribute.Value, "Button1");
writer.RenderBeginTag(HtmlTextWriterTag.Input);
writer.RenderEndTag(); //button
writer.AddAttribute(HtmlTextWriterAttribute.Type, "button");
writer.AddAttribute(HtmlTextWriterAttribute.Id, this.UniqueID + "butto_Foo2");
writer.AddAttribute(HtmlTextWriterAttribute.Value, "Button2");
writer.RenderBeginTag(HtmlTextWriterTag.Input);
writer.RenderEndTag(); //button
This way buttons are rendered on design view as well. The problem is that number of buttons to render is dynamic based on data in xml file (even if the data was static, the number of button is about 12 and I don't think it is wise to copy paste the same code above 6 times...). I thought by using loop for that:
int i = 1;
foreach (Button button in tb.Items)
{
writer.AddAttribute(HtmlTextWriterAttribute.Type, "button");
writer.AddAttribute(HtmlTextWriterAttribute.Id, this.UniqueID + "butto_Foo" + i);
writer.AddAttribute(HtmlTextWriterAttribute.Value, button.ButtonValue);
writer.RenderBeginTag(HtmlTextWriterTag.Input);
writer.RenderEndTag(); //button
i++;
}
tb is defined in OnLoad; On run time it works, but on design time I get error: > Error rendering control. And control is not being rendered.

Web Forms :: Loop Through Controls And Find Radiobuttonlist Controls?
Dec 13, 2010I have a web page with several panels. I one particular panel, I have several radiobuttonlist controls. I added a LinkButton to my web page and when clicked, I want to clear the values in all my radiobuttonlist controls. I have this so far:

Dim ctl as Control
For Each ctl In Page.Controls
If TypeOf ctl Is RadioButtonList Then
DirectCast(ctl, RadioButtonList).ClearSelection()

But this does not work. The If TypeOf ctl Is RadioButtonList Then line never finds a RadioButtonList control. How can I make this work?
