I have an app, where I have a form including 50 equal lines (50 user controls).
How do I set the css in the usercontrol, so e.g. the droplists-colors are different in line 1 and 2 (alternating)?
The way I have it now the 50 lines will we completely equal
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.
[code]....
This is page load
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{ [code]...
But in my ascx.cs when IButton1_Click is trigered My name is null
private string _sname;
protected void Page_Load(object sender, EventArgs e)
{ [code]...
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)
View 5 RepliesThere 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.
View 5 RepliesI have MainLayout.master that has UC_Menu.ascx on it.
I have a page named Customer.aspx that uses MainLayout.master. Customer.aspx also contains a UserControl named UC_Details.ascx.
How can I have UC_Menu.ascx call a function that is in UC_Details.ascx with this scenario?
I've seen a few similar examples, but none that match this type of layout.
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:

I have 2 usercontrol in my .aspx page.
usercontorl1:
<asp:textbox id="txt" runat="server"></asp:textbox>
<asp:button id="btn" runat="server" text="send" />
usercontrol2:
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 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

View 2 RepliesHow can I make a dll of my web application usercontrol?
I have usercontrol222.ascx, but I want to make a dll out of this usercontrol.
I am trying to create a user control in an ASP.NET MVC project. I basically have some formatted data that I want to put inside a repeater. In standard ASP.NET, I would populate the control something like this:
<asp:Repeater ID="MyRepeater" runat="server"
DataSourceID="SQLDataSource" DataMember="DefaultView">
<ItemTemplate>
<uc1:Control ID = "MyControl" runat="server"
Field1='<%#Eval("["Field1"]") %>' Field2='<%#Eval("["Field2"]") %>' />
</ItemTemplate>
</asp:Repeater>
And the control would have corresponding properties in the codefile. However, in MVC, I don't get a codefile as standard. I found this question that describes how to add one, but then wondered if there is a better way of doing this in MVC (I couldn't find any decent articles that said the recommended way).
In ASP.NET, you can add custom HTML tag attributes to a UserControl via
myLabel.Attributes['my-custom-attribute'] = "someValue";
// or Attributes.Add()
but how can I add an attribute that doesn't have a value? For example, (and I'm not saying that this is what I need) the W3C specification only needs the checked attribute present in a checkbox to consider it checked (instead of checked='true' or something).
<span ID="ctl-blah-blah-myLabel" my-custom-attribute>some text</span>
I'm looking into using something like this to tag specific elements on my page for some client-side behavior. I know that I can do the same with classes, but (1) classes are iffy to manipulate server-side, and (2) I kind of don't want to pollute my class declarations just for tagging (that may be weird for some, I know).
I have created a user control UserVote that has property to find total vote on particular question. Now I want to call it from an aspx page.The control code-behind (UserVote.ascx.cs) looks like:
public partial class UserVote : System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
DataTable dtVoteInfo = ShowVoteDetail(objectType, objectId);
if (dtVoteInfo != null)
{
if (dtVoteInfo.Rows.Count > 0)
{
int.TryParse(dtVoteInfo.Rows[0]["TOTAL_VOTE"].ToString(), out currentVote);
int.TryParse(dtVoteInfo.Rows[0]["MY_VOTING"].ToString(), out myVoting);
}
}
ltrVotes.Text = currentVote.ToString();
hfCurrentVote.Value = currentVote.ToString();
hfMyVote.Value = myVoting.ToString();
// ...snipped for brevity...
}
}
The control markup (UserVote.ascx) looks like:
<div class="vote-cell" style="width: 46px; height: 92px">
<img src ="~/UserControls/Vote/Images/Arrow Up.png"
id = "voteupoff"
runat = "server" alt ="vote up"
class="voteupImage"
style="height: 45px; width: 45px"/>
<div class="vote" style ="text-align:center; color:#808185;font-weight:bold;">
<asp:Literal ID="ltrVotes" runat="server" ></asp:Literal>
</div>
<img src ="~/UserControls/Vote/Images/arrow_down.png"
id ="votedownoff"
runat = "server" alt = "vote down"
class = "votedownImage"
style="height: 45px; width: 44px; margin-left: 0px;" />
</div>
My page code-behind (viewanswer.aspx.cs) looks like:
UserVote Voteing = (UserVote) **what i write here...**.findcontrol(voting)
Voteing.objectType =300;
Voteing.object id= 2;
My page markup (viewanswer.aspx) looks like:
<klmsuc:Voteing ID="Voteing" runat="server" />
I've created a usercontrol in VB that handles paging more efficiently than the DataPager (at least for very large datasets). I'd like to use it in a C# project, but I've been having trouble getting it to work. I've tried simply adding PagingControl.ascx to the C# project, but when I do that the markup and VB code behind don't seem to see each other. --Is this a namespace issue?
I've tried adding the PagingControl.ascx to its own VB project, then adding that project to the C# project's solution, as well as a reference. --That almost works. I can register the PagingControl usercontrol in the markup. I can access the usercontrol's properties in the code behind, but any property that involves the UI of the usercontrol fails. Its seems as if the usercontrol's form hasn't had a chance to load by the time the C# page's Page_Load event handler fires. --Maybe this is an "order of operations" problem? At what point in the C# page's lifetime should a usercontrol's form be loaded?
I'm trying to get add a link to a DNN usercontrol where when the user clicks it they can download a particular PDF. The code in my link click event is:
Response.ContentType = "Application/pdf";
Response.AppendHeader("Content-Disposition", string.Format("attachment; filename="" + "fileName" + """));
Response.BinaryWrite(Content);
Response.End();
When the link is click though the code runs through with no apparent exceptions but the dialog is never displayed. Similiar code to this has worked for me in non DNN applications and worked fine.
I got a user control that has a few links, one of them is "add article". It's placed on top of the article and bottom of it. When the user clicks on it, the text changes to 'article added'.
But the text only gets changed for one of the links which has been clicked on. How can I make it so that both text changes no matter which one gets clicked?
I have a C# library that gets built and gets placed into my website's bin folder. In my C# library I have a .ascx file and I'm trying to put another .ascx control in there. But I get this error:

This is in the top of my user control that I want to add to others:
<%@ Control Language="C#" Inherits="System.Web.UI.UserControl, ITextControl" %>
In my parent control, I have this:
<%@ Control Language="C#" %>
