Web Forms :: Dynamically Loaded Usercontrol Doesn't Fire PostbackEvent?

Jun 21, 2010

I am trying to dynamically load query form as a user control and build a sql statement based on user selection. I have a dropdownbox for Tablename, FieldName, ConditionalOperators and Value Field. Once the user makes a choice and causes a postback I loose my QueryForm (UserControl) and the selection Changed event never gets fired. I tried reloading the QueryForm on Page Init, still no luck.

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().

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.

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.

Forms Data Controls :: Create Textbox Dynamically In GridView And Retrieve The Value In Button Click Event?

Mar 24, 2011

I have a dropdownlist("ddlTemplate") control and a gridview("gvPlanning") control with 1 BoundField column, 1 TemplateField column and remaining columns will be generated dynamically from database.In TemplateFiled Column i have 3 image buttons viz: Edit, update and cancel.Gridview will be populated based on the selecteditem of dropdownlist.

if i click on edit imagebutton, i need to add textboxes dynamically in all the columns of that row except first 2 column. And if i click on Update imagebutton i need to retrieve the textbox values.we can add template field column for textboxes also, but why i am sticking to this method is.. the number of columns changes depending on the selecteditem from the dropdownlist. Eg: If i select india from dropdownlist the number of columns in the gridview would be 4 and if i select UK from dropdownlist the number of columns would be 9 likewise.

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:

C# - Button Event Handlers Do Not Fire On The First Click But On The Second Click After A PostBack

May 4, 2010

Background: I am customizing an existing ASP .NET / C# application. It has it's own little "framework" and conventions for developers to follow when extending/customizing its functionality. I am currently extending some of it's administrative functionality, to which the framework provides a contract to enforce implementation of the GetAdministrationInterface() method, which returns System.Web.UI.Control. This method is called during the Page_Load() method of the page hosting the GUI interface.

Problem: I have three buttons in my GUI, each of which have been assigned an Event Handler. My administration GUI loads up perfectly fine, but clicking any of the buttons doesn't do what I expect them to do. However, when I click them a second time, the buttons work.

I placed breakpoints at the beginning of each event handler method and stepped through my code. On the first click, none of the event handlers were triggered. On the second click, they fired.

Example of Button Definition (within GetAdministrationInterface)

Forms Data Controls :: Dynamic LinkButton Click Event Won't Fire?

Dec 21, 2010

I am working on an ASP.NET web application using .net 4.0 and VS2010.

I have a GridView and I am appending a row at the bottom to allow users to input data for "Adding" a new record.

The ONLY way I have found for this to work is to do this in the RowDataBound event of the grid. I can check to see if it is about to process the footer row then I know I am at the bottom and can insert this new row.

The row I am inserting contains a couple of TextBoxes and a LinkButton for the "Add" link.

If I just drop a LinkButton on my form and hook up the click event and I click the link button then the first thing that fires is the Page_Load event then my click event. However what is happening when I click the link button that was dynamically added to the GridView is the Page_Load event fires but the click event never does.

I have read 1000 threads saying to try to create the controls in the preinit() or some other event. In my case I can't. Or else someone would have to explain how to add the row to the bottom of the databound GridView.

Here is my code: (I removed creating the Textboxes because that is not part of the problem.
