Apr 16, 2013
I created a web site with admin control with C# ASP.Net. Admin can create a new button1 with button2.I did this. but when admin login again the created button is not seen.I guess I should save this created button at SQL Server but how should I do.
My code which create dinamically button is here:
Button btn2 = new Button(); btn2.ID = "btnEdit"; btn2.Text = txtKategoriEkle.Text; btn2.Attributes.Add("OnClick", "btnEdit_Click"); btn2.Attributes.Add("onclick", "my_javascript_function"); form1.Controls.Add(btn2);

I have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1
'use a try to target the button, use catch to handle if it's instead a label, only one cell per row.
Try
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try
Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.

m new to .NET. I'm trying to create a button dynamically with event by original button. The original button's click event response creates a button. The new button has a click event attached with a test message.What I have to do is onclick change background color of dynamically created button and grab id value to delete when button delete is clicked. Unfortunately, when I click the dynamically attached button,
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>

I've created an array of buttons like static Button[] myButtons = new Button[3];
and then creating and adding buttons to my panel like myButtons[i] = new Button();
myPanel.Controls.Add(myButtons[i]);
in my code behind.
How can I handle the events that occurs when a user clicks these buttons, like using OnClick="myMethod" with regular buttons?

I was wondering how about may I save the selection of the checked items of a dynamically created CheckBoxList?On postback the entire checkboxlist is lost. As the CheckboxList items are manually added in and not databinded, the selection is also lost.I was thinking of javascript, but i'm not sure how to implement it.

I am using the code below to recreate a modalPopup window. At each UpdatePanel refresh I "lose" the window but I recreate it again after my Panel is updated. This gives me the impression that the windows is always open. The only problem is after I drag and drop it to a different location, the window is recreated back in its original location:
if ($find(MPIDList[clientID]) == null) {
$create(Sys.Extended.UI.ModalPopupBehavior,
{ "BackgroundCssClass": "modalBackground",
"CancelControlID": CancelControlIDList[instanceId],
"DropShadow": true,
"X": 50, "Y": 250,
"PopupControlID": PopupControlIDList[instanceId],
"PopupDragHandleControlID": PopupDragHandleControlIDList[instanceId],
"id": MPIDList[instanceId]
}, null, null, sender);
So I was trying to do the following:
1 - Initialize a global var for X and Y with the static values of 50 and 250;
2 - Show the window and drag it to a different location;
3 - UpdatePanel is refreshed and my Gridview is data bound with new data
On step 3 above I need to find a way to save the current window position BEFORE UpdatePanel is called and apply the saved position AFTER the UpdatePanel call is finished.

I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.

I have a modalPopupExtender in my aspx web page pointing to a Panel and in Code-Behind I create buttons which I want them to show the modalPopup, so I have:
buttonX.OnClientClick = "javascript:$get(" + modalPopup.ClientID + ").show();";
but instead it just does a PostBack, even if I put "return false;" at the end of the past code.

I have a writing a web page that will use several different types of control. The control types will depend on the data being read from a SQL database. The following is my code that decides what control to add to the page:
Select myReader.GetString(1)
Case "DatePicker"
Dim bdpAnswer As BasicFrame.WebControls.BasicDatePicker = New BasicFrame.WebControls.BasicDatePicker()
bdpAnswer.DateFormat = "dd/MM/yyyy"
divAnswerContainer.Controls.Add(bdpAnswer)
Answers.Controls.Add(divAnswerContainer)
Case "DropDownList"
Dim ddlAnswer As DropDownList = New DropDownList()
divAnswerContainer.Controls.Add(ddlAnswer)
Answers.Controls.Add(divAnswerContainer)
Case "RadioButton"
Dim rbAnswer As RadioButton = New RadioButton()
divAnswerContainer.Controls.Add(rbAnswer)
Answers.Controls.Add(divAnswerContainer)
Case "TextBox"
Dim tbAnswer As TextBox = New TextBox()
divAnswerContainer.Controls.Add(tbAnswer)

I'm making a custom modal popup using a bunch divs where the programmer can set how many buttons thay want to apprear on said popup programatically using a function. It works. The only problem is that when the programmer specifies the number of buttons he/she wants it wipes out the skin information for the whole control. If I comment out the call to CreateChildControls the skin works fine, but the new buttons are not created.
In my CreateChildControls function the first thing it does is call Controls.Clear(). I assume this is what's wiping out the skin information, but it's kind of necessary to prevent controls with duplicate IDs.

I have some CSS that uses lists to create 3D buttons styles similar to the link below:
http://articles.techrepublic.com.com/5100-10878_11-5323375.html
My problem is I have buttons which are server controls and thus render html buttons.
The question is how would I rewrite my button code to use lists and hyperlinks so I can apply the CSS which has been already written?
All I am doing in my button code is within the onclick event setting a string value and calling a method by passing it that string value.
I'm after is some onclick event equivalent i can hook my code into for hyperlink controls.

My application I am using pagination.Using pagination i bind the records with listview control.
I generate the buttons dynamically according to the number of pages which is calculated from number of records returned from dataSource.when i click on a dynamically generated button its corresponding event handlers methods should get evaluated.Since asp.net page is stateless I can't keep the state of that dynamic controls after any postback.
Just Now I have seen the Article "How to get the Id of Control that cause postback in asp.net?". I got some idea from that article. Any example for "Creating link buttons dynamically and handling its corresponding event handler in Asp.Net".

I'm creating 14 textboxes for every day in a month and user can select the month so i have o create them dynamically. But i can't reach the values in the textboxes.
When i don't create them dynamically like
<asp:TextBox ID= "TextBox1" name="TextBox1"> </asp:TextBox>
I can get the value from the C# side by using the
((TextBox)Page.Form.FindControl("TextBox1")).Text
However this moethod doesn't work for the textboxes that i created dynamically. I'm creating them in a loop it's something like;
[Code]....
Then i add the text box to the necessary places at my table.However i can't reach the textboxes when i use the same method
((TextBox)Page.Form.FindControl("!A uniqe ID!"));
It gave a null value...
