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);
}
but btn is null. How can I do that ?
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.
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)?
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.
I have a dynamically loaded usercontrol
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ucEditPanel.ascx.cs"
I am trying to bind a click event to a button within a usercontrol at runtime. The code I have written works form a plan old webform but the event is just not binding with in the control.
Here's my code. First the page:
[code]....
When I run the app the myEvent from inside the control is never hit but myevent on the webform is hit when I click its button.
Can anyone tell me how I can bind the user controls button dynamically from with in the user control?
I've seen code to handle MasterPage events in the content Page, but if I'm loading a UserControl dynamically into the Page, can I handle the event in the UserControl instead?
Basically I have a button on the MasterPage, when it's clicked I need to make the UserControl do something, such as display text or change a value in a form.Failing that, is it possible to make an event from one dynamically loaded UserControl fire in another on the same page? I could then replace the button in the MasterPage with one in another UserControl
In the UserControl I am adding dynamic ImageButtons depending on the condition When the page loads and I click on Edit button I have no problems and btnEdit_Click is fired. But after that (btnEdit id removed and btnSave is added) when I click on btnSave the btnSave_Click event does not fire. What could be the problem?

I have a Page, that has UserControl1.
UserControl1 has UserControl2.
When the page loads UserControl2's Load event is not fired at all.
I have created my own custom usercontrol(.ascx) consisting of labels and image etc. I need to be able to click on this control but i dont know how to add a click event to it.
Basicly i want this whole control be like a huge button which i can click on.
I have created the usercontrol. There is event :
public event System.EventHandler MemberSelectionChanged;
I have called this event in aspx page like this(given below). It working fine. Is there any other way to call the user control event in aspx page.
this.ucMemberList.MemberSelectionChanged += new EventHandler(MemberList_MemberSelectionChanged);
I have a user control that has an event that checks if a textbox is empty and does other processing...this event would also set a publ;ic property on the user control to a boolean value.
1) On the host page/parent, I want to click a button that will set off the event explained above.
2) Also, how do I reference the user control on the host page?
I am trying to add an instance of UserControl each time on button_click event, it works for the first time only. I am adding IDs to user control by appending integers from ViewState. Why does it not add work for subssequent clicks. Here is the simplified version with the same behavoir.
protected void Button1_Click(object sender, EventArgs e)
{
HtmlButton btnClick = new HtmlButton();
btnClick.ID = "bt" + Append.ToString();
btnClick.InnerText = "Button 1";
MainArea.Controls.Add(btnClick);
}
I created a usercontrol I use to build up a list of at runtime. Each instance represent one category, and it will have a title, description and a button taking the user to the page displaying all articles for that category.
The control's members:
Code:
public string Title { get; set; }
public string Description { get; set; }
public int CategoryId { get; set; }
And the markup:
Code:
<h4><a href="#"><%=Title%></a></h4>
<div>
<p><%=Description%></p>
<p>
<br />
<asp:LinkButton CommandArgument="<%=CategoryId %>" runat="server"
CssClass="small btn red fr" onclick="LinkButton_Click">Go To <%=Title%></asp:LinkButton>
</p>
</div>
The code show's just fine, but the click even never fires when I click the button:
Code:
protected void LinkButton_Click(object sender, EventArgs e)
{
var x = sender as LinkButton;
string z = x.CommandArgument;
}
Obviously doing it wrong, but then, did not touch webforms in a long time.
I need to load a web user control dynamically.
Looking at [URL] it states that the page lifecycle events are not fired.
I thought I might be able to raise the events through reflection. I cannot figure how to fire the events, am I missing something?
I have a login.ascx control with three controls (LoginName, Password and btnLogin) , I want to rase a click event on this button from .aspx page because some restriction is there so that I am unable to write any code on .ascx page.I am bale to put loginName and password on .ascx by using query string but unale to raise event.

I have a dynamically created user control which is accomplished usingLoadControl().
When I debug, the LoadControl call is called once, however the Page_Load inside the user control is called twice. On each occasion, the postback property is false, so it seems somehow the Page_Load event is called outright 2 times and nothing to do with any postback?
I have a page where I add a dynamic user control in the Page_Load event based on criteria.
The control is a simple form with a save button. The problem is the _Click event never fires for the button. It will postback the main page the control is within, but not the code behind for the control...so I never get the button click even, and therefor can't execute the save code.
Tried it in the init, tried adding the control to a placeholder, tried a lot of various things but nothing seems to work.
Code:
If cb_business_profile.Items.Count = 0 Then
Dim u_pnl_content As UpdatePanel = Page.FindControl("u_pnl_content")
u_pnl_content.ContentTemplateContainer.Controls.Clear()
Dim business_profile_detail As Control = LoadControl("~/controls/business_profile_detail.ascx")
[Code] ....
i have a very strange issue with a user control we are dynamically loading on an asp.net web page(.net 2.0). the user control has 3 dropdowns, one of which has a selectedindexchanged event attached to it (which loads the third dropdown with a set of values).
the weird thing is, if there are currently any invalid fields (where field validators have been activated) in other parts of the form, when you go to select the drop down in question on the FIRST change it does nothing, but then when you change the index again it works perfectly! i dont understand how the event wont fire for the first change, but for every change thereafter.
However, if all these fields are filled in correctly above the usercontrol, it fires off the selectedindexchanged event correctly.
in regards to validation i have disabled ALL POSSIBLE validation in order to try and eliminate it as a culprit, so i dont understand how validation can be affecting the usercontrol.
As you said that for storing use data table and make property in the .ascx.cs file but I have problem that I m not able to get that property in the .aspx page. How to add multiple instances of web usercontrol on page on button click event?
