I have on my Page a Label control and custom UserControl. I want that, when something appears in the UserControl, it shoud change e.g the Label's Text property (as I mentioned, the Label doesn't belong to the UserControl). How to do that ?
View 4 RepliesI tried both, loading the usercontrol when needed and I also tried adding it directly into the aspx.
Nothing worked. With the second one (what's meant to be the easiest option) I tried with delegates and events (but can't access de usercontrol event from page) and tried with properties (I can access properties but they're always empty)
I have a DetailsView control bound to an ObjectDataSource within a User Control (.ascx). It appears that the DetailsView.OnDataBound event is being fired on every page load or postback.
I do not see this behavior with a similiar DetailsView directly placed on an aspx page.
So what I'm trying to accomplish is this

The user control has public properties named accordingly and the page has protected properties accordingly which I've verified have the desired values.
For some reason the values are always empty strings or 0s in the usercontrol, no matter what the page property is.
I have a UserControl I created for Navigation that is added to a master page. In a host page, I have a drop down list that I would like to change the value of a dropdownlist in the user control when changed.
I've tried to use the findControl to get the Hyperlink control I'd like to change the value of, but it's always returning nothing. I am thinking this is because the control is nested in a master page. how I can change the value of this item based on the value of a dropdownlist in the aspx page?
I have a page for webparts and have a usercontrol in the declarativecatalog. The user control had a gridview. I need to click (select) an item (row) in the gridview and change the selected value of the DDL in the parent (I guess this is the appropriate term) page.
<%@ Page Language="VB" MasterPageFile="~/MyStuff/MyStuff.master" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="MyStuff_Default" title="MyStuff" %>

I have a requirement to hide certain buttons in a standard MOSS page. The buttons are generated by a Microsoft UserControl and some buttons must be hidden before displayed to the user. This page cannot be customized, so the only approach is to have an httpmodule which would use some Javascript and C# to hide the unwanted buttons. So my question is during which event should the javascript be used to pick out the DOM elements and set their visible property? Can anyone give a code example?
View 2 RepliesI have a particular scenario and I would like to know how I can implement it in the most efficient way. I also have some queries related to this. The application is a AJAX 1.0-Enabled ASP.NET 2.0 Web application.
I have a link, which when clicked I need to show a pop-up div. The contents of the div will be displayed using a usercontrol. The usercontrol will display the contents based on a query string value.
I would like to know:
1. How can I implement this in the most effecient way. I don't want to use a separate page on which I will have the usercontrol and then display the page in the div.
2. Suppose I call a JS function ShowDiv() on the click of the link, to display the pop-up div. Say, I call the function this way ShowDiv('querystring'). Now how will I pass the value 'querystring' to my usercontrol.
I want to embed some image and java script file in usercontrol and extract them with code like this

i tried similar code that use this technique in custom controls , and it works ...
but i want use this technique in usercontrol ,
can any one put a sample source code or explain how can i use this technique in usercontrol ?
I have created lots of UserControls, but never tried CustomControl.Recently i created a Photo Gallery UserControl using Listview & Visual LightBox.Now i want to publish it as CustomControl.Here is my UserControl's code :
<link rel="stylesheet" href="LightBoxGallery/css/vlightbox.css" type="text/css" />
<style type="text/css">

I created a customDropdown usercontrol with Events and It worked fine.
Now I stored the path of the ascx file in the database table and i want to Load the ascx file and handle the Events dynamically in an aspx page.
To Load the usercontrol and access the public properties and method, I need to know the object i am trying to load, right?
For Example
FeaturedDDL c = (FeaturedDDL)Page.LoadControl("~/FeaturedDDL.ascx").
But I dont want to hardcode objectType "FeaturedDDL", coz i dont have that stored in my Database field.
Since I am loading the usercontrol by getting the path and name of the usercontrol from the database table,how will I know the ObjectType at that time?
How to accomplish that and also how to handle the events for these type of situation?
I have a user control that consistes of a dropdown menu, a label, a textbox and a button. It resides in a html table, what i would like to do is on a keypress, such as the "insert" key, i would like to add the same control again directly on the next row, I have used programs that do this, but for the life of me can't figure out how its done...

I'm working with a simple UserControl someone at my company created. It's basically just a DropDownList with a RequiredFieldValidator and some added properties (such as "Required", which controls the CSS styling of the DropDownList and whether the RequiredFieldValidator is Enabled or not).
Here is an example of the UserControl usage where a SqlDataSource is used to populate the ListItemCollection. I'm trying to specify an intial ListItem below (and would like the ability to add multilple ListItems if necessary) but can't seem to get this to work...
[Code]....
My code-behind looks as follows:
[Code]....
I've found several posts related to this but cannot seem to get the declarative ListItem to be added to the DropDownList.
I understand that using a WebControl is another option, but I'd like to learn how to get this method to work if possible.
How can I create a UserControl with a collection-type property which has a collection editor?
I've a CompositeControl with an ArrayList-type property which has CollectionEditor-type designer. You can see this property on Properties window with a "..." button which launches a collection editor. This works fine and all but I want to apply the same to a UserControl and I've couldn't manage to pull it off so far. I've done the same thing what I've done with my CompositeControl but the property either doesn't even show on Properties window of the UserControl or shows as a single value property with no "..." editor button.
This is what I've done with CompositeControl:

how to access "custom usercontrol's properties" while the usercontrol itsef has been added programaticly by code.
On MasterPage i have function below, how call this function on test.ascx form on button click.
public void HideBtnLogin() { string session = Session["userCode"] as string; if (String.IsNullOrEmpty(session)) {
lbtnSignInTop.Visible = true; lbtnSignUp.Visible = true;

else { lbtnSignInTop.Visible = false; lbtnSignUp.Visible = false; } }
I have a ShoppingCart UserControl on MasterPage. I have a following functionality: User adds item to the cart. after clicking the button "Complete Sale" in UserControl the page is redirected to "CustomerInfo.aspx" and after filling the Customer information and clicking on submit which is on CustomerInfo.aspx page i want to call the "Complete Sale" click event of UserControl from "Customerinfo.aspx" page.
Customerinfo.aspx.cs
protectedvoid btnSubmit_Click(object sender, EventArgs e)
{
try
{
bool val = false; int retVal = 0;
CustomerBiz objCust = newCustomerBiz();
objCust.FirstName = txtFirstName.Text.Trim();
[code].....
Here the Button text changes in UserControl. But i am not able to call the Click event of this button from CustomerInfo.aspx (ContentPage)?
On masterPage i have button btnTest, how hide button from masterPage on userControl.ascx
example:
btnSecondPage_click
{
btnTest.visible = false;

I want to create a custom control where I define several specifically named DIV sections. The code-behind logic of the custom control will perform operations on these named DIV sections. The page where the custom control is hosted needs to be able to add named controls to the DIV sections and perform operations on these named controls added to the DIV sections.
Let me explain a little further. In the custom control, I want to have code behind logic that fires the following Page Event and uses a condition to make one or another specifically named DIV section visible or not:
< _
ToolboxData("<{0}:BaseDetails runat=""server""></{0}:BaseDetails>") _
> _
Public Class BaseDetails
[code]...
how can I create a custom control which is able to generate the named DIV sections "DetailsNameDiv1" and "DetailsNameDiv2" where my custom control can check a condition and make one or the other visible. Also, I need to be able to add controls to these named DIV sections when I host the custom control and the control that I add to the named DIV section needs to let me set values of these controls from the code behind logic of the page (or usercontrol) where the custom control is being hosted (in my example, I am adding TextBox controls that I want to set the Text property from a SQL Data Reader).
I have class that Inherit from UserControl Class.
public class Module : UserControl
{
// Custom Property And Method
}
How can i load a UserControl (.ascx) and convert to my Module Class?
UPDATE :
the error is : Unable to cast object of type 'ASP.UC_acsx' to type'BICT.Module'
my class is like this :
namespace BICT
{
public class Module : UserControl
{
public Module()
{
// Some Initial
}
// and some extra property exp.
public int Index{ get; set;}
}
}
is somthing wron with my code?
Supposing I have a user control like this <MyTag:MyWidget runat="server" /> I am wondering if I can do something like <MyTag:MyWidget runat="server" MemberHeight="400" PublicHeight="200" /> So that in MyWidget.ascx I can have <div height="<%=IsLoggedIn ? MemberHeight : PublicHeight%>"> or something like that...? Because I want the height to vary in each page that is using this widget.
View 2 RepliesI 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.
In an asp.net page, how to get a reference of a custom webcontrol from a usercontrol?
<%@ Register Src="~/Controls/PressFileDownload.ascx" TagName="pfd" TagPrefix="uc1" %>
<asp:Repeater id="Repeater1" runat="Server" OnItemDataBound="RPTLayer_OnItemDataBound">

System.Web.UI.WebControls.Label lbl;
System.Web.UI.WebControls.Literal lit;
System.Web.UI.WebControls.Image img;
System.Web.UI.WebControls.HyperLink hl;
System.Web.UI.UserControl uc;
I need to set the ParentItemID variable for the uc1:pdf listed inside the repeater.
I thought I should be able to find uc by looking in the e.Item and then setting it somehow. I think this is the part where I'm missing something.
uc = (UserControl)e.Item.FindControl("pfd1");
if (uc != null) { uc.Attributes["ParentItemID"] = i.ItemID.ToString(); }
Also tried this with similar results... when I debug inside my usercontrol (pfd1) the parameters I am trying to set have not been set.
uc = (UserControl)e.Item.FindControl("pfd1");
if (uc != null)
{
uc.Attributes.Add("ContainerID", _cid.ToString());
uc.Attributes.Add("ParentItemId", i.ItemID.ToString());
}
UPDATE: It looks like my controls are not connected by a namespace. I've wrapped by the parent control (Layer) and the PressFileDownlad control in a namespace "MyControls". Also updated their Inherits reference on the aspx to read "MyControls.xxxxx". I'm able to type "MyControls.Layer" inside the code on layer.aspx.cs but I'm not able to get "MyControls.PressFileDownload"
Is it possible to change the ascx file used by a usercontrol at runtime?
For example in my page i have
<ctl:SampleControl runat="server" />
in the web.config I have
<controls>
<add tagPrefix="ctl" tagName="SampleControl" src="~/UserControls/SampleControl.ascx" />
</controls>
At runtime I would like to be able to change the ascx to another path, it would still be inheriting from the same usercontrol codebehind, it would just be a different template.
there's a label control on my master page..if its value is "Value1" ,I want this CSS Sprite to display on my webform..if the Value is "Value2"..the CSS sprite should use some different image..just the image needs to be changed ..nothing else in that Sprite..
I found out that I can use "FindControl" method to find out what value that Label Control of Master Page's currently got..
Now how do I change that image on the banner ?? How do I go about it ? Also that CSS Sprite now is a user control named "myBanner.ascx"(earlier was an aspx file)..Now do I need to make 2 diff usercontrols or I can implement some logic in one usercontrol itself ?
Should I make 2 copies of this "myBanner.ascx" with JUST the "image name" changed in its CSS ???
Hope its not confusing..Actually I am lost :/
What I want is ONE banner which has been made using CSS Sprite ..Now if the "Label Control's "value in the master page is "Value1" then the image to be used on that banner is "IMAGE1" else if "Label Control's" value is "Value2" then "IMAGE2" should be used in that sprite..
