To Handle A MasterPage Event In A UserControl (C#)?

Aug 19, 2010

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

VS 2010 Linkbutton Click Event In UserControl

Oct 17, 2011

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.

Web Forms :: UserControl Page_load Event Fires Twice Using LoadControl?

Jan 5, 2010

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?

VS 2010 Dynamic UserControl - Postback Event Not Firing

Feb 8, 2012

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] ....

Dynamically Displayed Usercontrol Not Firing Postback Event On Select?

Aug 20, 2010

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.
