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','')
im creating a button control in page int and im assing a click event for the button control. here the click event is not firing for the first time. here is my code.
[Code]....
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().
I want to make a website having the following UI.

I am tring to get modal popup when enter value in one text box then click the button modal popup will show , without entering the value in textbox, button validation to enter the value. I written javascript validation to the button ,it showing alert message, but after showing alert message clicking ok button in alert window modalpopup is showing . How can i resolve it .
<asp:TextBox ID="TextBox1" runat="server" />
<asp:Button ID="Button1" runat="server" Text="Show popup" />
Here java script validation :
function Validate() {
if (document.getElementById("<%=TextBox1.ClientID%>").value == "") {
alert("Please Enter any Value ");
document.getElementById("<%=TextBox1.ClientID%>").focus();
return false;
}
}
My page contains a button [Button1].I've dynamically created a new button [Button2] in the Button1_Click event and and assigned event handler also.But when clicking on Button2, Button2_Click event is not fired.I think its because the page looses dynamically created Button2 after post back, since it is created in Button1_Click event.Is there any way to maintain Button2 on page and raise Button2_Click event ?
View 5 RepliesAm adding a sample webpart dynamically in which i add a Button Control.the isssue is Event is getting fired when i Click on the scond time and the other issue is the web parts are getting duplicated for each postback.
View 1 RepliesI am creating two buttons within the StoryGet() method, first when the page loads. When one of the buttons is pushed, lets say the left one - I want to call another method - "ButtonLeft_Click"
Ive used this same solution in other sites and it worked. With this solution, click event never fires.
If I move the StoryGet() call from Page_Load to PageInit() the button event fires, but because this event also calls StoryGet() the method runs twice, which I don't want.
I tried adding this to page_init so the original StoryGet() method only gets run the first time the page loads unless the method is called directly but then the page loads, but the button click event doesn't run again
if (!this.IsPostBack)
{
piccount = 0;
StoryGet();
}

View 1 RepliesHow can i dynamically add textboxes and dropdown lists on a button click. I'll be showing 4 text boxes and 1 dropdown list initially with a link button ADD MORE, Then after clicking ADD MORE button i need to generate same 4 text boxes and dropdownlist exactly in the below row as in EXCEL sheet.
I'm having a SQL table with 4 textboxes and a drpdown list values as columns and i need to insert them into the database. i previously worked on the same requirement where i've collected multiple values frm a listbox control and looped all the selected items and comma seperated them and inserted them into table(here the case is different, there is only one row so it became simple and straight forward during insertion). Now i need to loop throguh all the 4 textbxes which user enters and need to insert those 4 textboxes values into DB under same columns.
1. When executed I have a "Add Building" and "Click here to add tower" on the page.
2. When clicked on "Add Building" a editable gridview appears when I enter the text and say update.
3. When I click on "Click here to add tower" another button "Add Tower" is displayed on the
page.
4. On this "Click here to add tower" event I have called the usercontrol, where the usercontrol has a editable gridview and a button called "Add Tower".
5. When I click on "Add Tower" a editable gridview should be displayed but the editable gridview is not displayed ,it disappears.

I have Gridview and Button Control on Form.i want to Add Dynamically TextBox And DropDownList In Gridview on Button Click Wich is placed outside of Gridview.
When i click on Button -> One TextBox and One Dropdownlist which contains values bydefault 1,2,3 should bind to gridview. Button is placed outside Gridview.
I have a dynamically loaded usercontrol
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ucEditPanel.ascx.cs"
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.

I was thinking about the performance when I use code to hide some control in aspx page using delimiters or in cs file. For e.g. If I have a panel and I want it to get shown following some condition, so I can achieve this by two ways
1: Using code in aspx file, something like this
<% if(isAllowed) { %>
<asp:Panel ...></asp:Panel>
<% } %>
2: In the code file, something like this
<asp:Panel ID="pnlMyPanel" Visible="false"></asp:Panel>
And in cs file
if(isAllowed)
pnlMyPanel.Visible=true;
In my view, first way should be good as it will not at all create any Panel in the page. Am I correct here?
am adding control dynamically in button click event in asp .net i have one more button when i clicked the added control is disappeared .
As per my need I want to dynamically load accordion pane and inside that I want to load an ascx control. I am attaching my code for reference. But when I run my code it does not create separate pane.
Sample Code part:
protected void Button1_Click(object sender, EventArgs e)
I have put my gridView inside an UpdatePanel with Timer control for auto refresh.The gridView has a linkButton column which is bounded to referenceNo column from database.
On click of this link button i want a panel to get visible. This Panel contains details corresponding to the referenceNo shown in differnt controls (mostly texboxes). Do i necessarily need to put the panel inside the Update Panel.If not how do i do it?
I have tried putting panel outside UpdatePanel, but it doesn't show panel on clicking the linkbutton nor does the values are updated inside this panel (if panel's visibility is set to true by default for testing purpose).
