Web Forms :: Handling Button Clickevent In Usercontrol That Is Being Loaded Dynamically?

Nov 2, 2010

I have ASPX page named ArtifactReporting.aspx where I have 3 linkbuttons. For each button I have 3 different UserControls to be loaded dynamically. So I have written for each click

UserControl uc = (UserControl)this.LoadControl("<ASCX page name>");
divArtifact.Controls.Add(uc);

Now in one of the ASCX page I have a server side button. When I click on the button, the content of the ascx is going off, which is correct, because the page post back is happening and in Page_Load I have not written anything that will load the ASCX page.

how to go about this? I need if I load an usercontrol dynamically, I should be let the users carryout operation that usercontrol.

UpdatePanel Dynamically Loaded Web UserControl Will Disappear After Clicking Any Button Inside The UserControl?

Mar 17, 2011

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.

Usercontrols - Button Click Not Caught (button In User Control Which Is Dynamically Loaded In Repeater)?

Jun 4, 2010

I have written a user control that captures some user input and has a Save button to save it to the DB. I use a repeater to render a number of these controls on the page - imagine a list of multiple choice questions with a Save button by each question.

I am loading the user control inside the repeater's ItemDataBound event like this (code simplified):

[code]....

The problem is that when the Save button is clicked, the page posts back, but lbnUpdate_Click is not called. The Page_Load event of the page itself is called however.

I should mention that the repeater is part of a user control, and that user control is loaded inside another user control (this is a DotNetNuke site which makes heavy use of user controls). The Save button link looks like this:

javascript:__doPostBack('dnn$ctr498$AssignmentsList$rptAssignments$ctl04$ctl00$lbnUpdate','')

Web Forms :: Dynamically Loaded User Control Button Event Not Firing?

Mar 11, 2011

I have a aspx page, default.aspx, with an user control in it. Inside the user control (UC 1) there is a DataGrid. When the DataGrid is loading data with ItemDataBound, I need to dynamically load another user control (UC 2) for each row in the DataGrid. UC 2 has a Button ( BTN )with an eventhandler associated with it in code behind.

User control loading is fine, and the Button, BTN, is there. However, when I click the Button, the eventhandler is not reached, not firing, even though the page does postback. I googled for this issues, and I know the dynamically loaded user controls need to be loaded every time the page is postback. In my case, it needs to be loaded each time the datagrid is doing ItemDataBound. I did it and even hook up the eventhandler with button click event each time when the user control is dynamically loaded. I set EnableViewState to true on the Page and controls.

The following is part of the code from UC 1, AcctPaymentDetail is UC 2 in the code.

[Code]....

And the following is UC 2 the is being loaded:

Handle Button Click Event From User Control Loaded Dynamically

Jul 31, 2010

I have a blank user control (child) and during Page_Load i create some text boxes and a button. I also add an event to the button.

I then load that user control dynamically from a placeholder in another usercontrol (parent). Both controls are rendered correctly but when i click on the button, the event isnt fired. how to handle the event?

Child code:

[code].....

If i use the child control directy (ie without the parent the control) the click event is raised and handled nicely. But when i use the parent control, the debugger wont even hit a breakpoint inside UpdateButton_Click().

Custom Server Controls :: Handling Events In Dynamic Usercontrol?

May 27, 2010

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?

</Triggers>
</asp:UpdatePanel>
</div>
</div>
</form>
</body>

It is a header with two columns: On left column there is a TreeView, and on the left there is nothing (now there is a label to try the thing that I want to do).

When user select a node on treeview a click on Edit button. Code for click event is:

protected void Edit_Click(object sender, EventArgs e)
{
if ((DestinationTree.SelectedNode != null) &&
(DestinationTree.SelectedNode.Depth > 0))
{
BaseControl baseControl = new BaseControl();
UpdatePanelRight.ContentTemplateContainer.Controls.Clear();
switch (DestinationTree.SelectedNode.Depth)
{
case 1:
baseControl = (BaseControl)LoadControl("~/DynamicControls/Control1.ascx");
break;
case 2:
baseControl = (BaseControl)LoadControl("~/DynamicControls/Control2.ascx");
break;
case 3:
baseControl = (BaseControl)LoadControl("~/DynamicControls/Control3.ascx");
break;
}
UpdatePanelRight.ContentTemplateContainer.Controls.Add(baseControl);
}
}

Depending on node selected depth is going to load a custom control dynamically. It works, but when the user select another node on treeview, the original label is reloaded on right column.

Web Forms :: Dynamically Loaded User Control Not Getting Selected Value?

Nov 5, 2010

I have created a user control that contains two asp calendar controls. I need to add this user control twice on the same asp page, let's say for Check in date and Check out date. Since the two are conflicting to each other when I add it twice statically, I now dynamically add them on button click so that each time only one control is loaded. The problem is, when I select a date on a calendar, it seems that the selection event is not happening at all. Of course, I am not getting any date.

Web Forms :: When To Wire Up Event Handlers For Dynamically Loaded User Controls

Jul 15, 2010

I have a situation where I dynamically load one of twenty user controls at a time in an ASP.net web page. Based on much reading I've done, I understand that I am to reload the user control upon postback via the Page_Init event handler. This I've done and it seems to work fine.

But now I would like to wire up assorted controls in the user controls such that when the value of each is changed, an event is fired and the web page is notified. Here's an example of how I'm doing that:

userControl.NewData_Handler += new EventHandler(UserControl_NewData_Handler);

There's a problem though. Because the user control is being done in Page_Init (ie. before Page_Load) I don't believe that a line of code such as the one above can function yet.

So I'm wondering what the best practice to do this is. It occurred to me that perhaps I could execute the line in the Page_Load event handler but I'm not sure if that's correct or not.
