i have created Array of Linkbutton and when user click on link button it will create an array of Radio Buttons but it requires Postback all time so page load takes more time...
View 2 RepliesI have a link button let's say LB1 wherein on click of the LB1 a modalpopupextendar will open up with a textbox where we can enter the message and onclick of Ok button the entered message will be saved. Let's say we have repeated the above steps for thrice. So there will be three rows created in DB. Let's say column name UID is the primary key.Now, I am displaying the each message inside a panel along with Link Button(LB2) which is created dynamically while reading the text. So,The first row will contain
UID:1 Message:Message1
Comments:Comments Link Button(LB2)
The second row will contain
UID:2 Message:Message2
Comments:Comments Link Button(LB2)
The third row will contain
UID:3 Message:Message3
Comments:Comments Link Button(LB2)
When I click on Comments Link Button(LB2) a modalpopupextendar will popup wherein we can enter the comments. Let's say we are clicking on LinkButton of Message 1, a pop up opens and after entering comments and ok button the comments are saved for all the three messages instead of saving it for message 1, i.e I couldn't find the unique id of the message.
I wanna to pass query in a dynamic link button. I can add it dynamically but unable to pass query on that. Apart from that LinkButton_onClick handler is not working.
View 1 RepliesWhat I'm trying to accomplish is to set my dynamically created linkbutton with a onClick command so when click it will run a method in the code behind. This is my code:
protected void Page_Init(object sender, EventArgs e)
LoadLeftSide();
private void LoadLeftSide()
{string filepath = Server.MapPath("DataSource.xml");
List<Post> list = PostHelper.GetAllPosts(filepath);

I am adding numerical page links for paging of a repeater. I have used on of the numerical paging samples as my base. It works fine if I have less pages than my maximum total links. Eg if I have 11 pages, but only showing page 1-10 plus a next for the 11th, I get an error about duplicate control ids. I changed my control id to use a Guid in the string to keep it unque, after making this change the event handler never fires
private LinkButton createButton(string title, int index)
LinkButton lnk = new LinkButton();
//lnk.ID = System.Guid.NewGuid().ToString("N") + "_" + index.ToString();//Event does not fire if I set ID with Guid

Ive been playing around with the default ASP.NET web application template and the following code throws an exception:
Object reference not set to an instance of an object.when clicking the created button.
Note 1: The markup is just a blank page with a placeholder in it - see below.
Note 2: Substituting Button for LinkButton, and the code does not throw an exception and works.
public partial class test : System.Web.UI.Page
{
protected override void OnInit(EventArgs e) [code]....
I know this question has been asked thousands of times, and I've struggled with it before, but for some reason, I can't accomplish what I want to accomplish... I have a dynamically added LinkButton that when clicked will dynamically add a control (in this example, a textbox) to the same panel. The intent is to continuously add on as many controls as times the LinkButton was clicked (i.e. I click it once, one box, then another click will give me 2 boxes, another click adds a 3rd). In the code below, I use the current date and time serialized to create a unique ID for each textbox control.
When I execute the code, clicking "Add Filter" will generate a new textbox, but once clicked again will create a new one, and dispose of the one before it. Instead, I want to persist the previous textbox as well as any data submitted within it.In the aspx:
<asp:Panel ID="pnlFilter" runat="server">
</asp:Panel>
In the aspx.cs:
protected void Page_Init(object sender, EventArgs e)
{
LinkButton lb = new LinkButton(); [code]....
In my code I create a table dynamically and I try to restore the table after a postback. But although I recreate the table during the Page_Load event with the same id's before,the table doesn't appear with the same state and values as before.
I think it will be a typically beginner error, but I wasn't be able to locate the error whereas reading different posts and tutorials related to this topic.
//Code behind
protected void Page_Load(object sender, EventArgs e)
{
if (Page.IsPostBack & _hfsubmittedURL.Value == "tbCreated")
{
TableRow row1 = new TableRow();
[Code].....
I know this has been asked before, but I feel like I'm losing my way trying to follow the other examples out there. Does anyone see a straightforward solution to my particular problem?
Goal:
Two column Master Page
Left column contains a list of [stuff] (I'm trying a Repeater with LinkButtons)
Right column contains a TabContainer which will add dynamically created tabs when buttons on the left are clicked.
Left side looks like this:
<asp:Repeater
<ItemTemplate>
<asp:LinkButton ID="lbShowReport" runat="server" Text='<%# Eval("Title") %>' CommandName="Select">
</asp:LinkButton>
<asp:HiddenField ID="hfReportID" runat="server" Value='<%# Eval("Id") %>' />
</ItemTemplate>
</asp:Repeater>
I had initially been creating tabs in the LB's OnCommand event, but of course this means that any tab generated by one click is lost if the user clicks another LinkButton.
So I moved the code to create a new tab to the OnInit section of the page and attempted to loop through the RepeaterItems comparing the UniqueId of each LinkButton until I found the one that was clicked using Request.Form["__EVENTTARGET"].
When I tried to loop through the RepeaterItems, however, the count was always 0, and the Repeater would not populate.
So now I am rebinding the Repeater in the Init section on every post-back - this allows me to find the LinkButton that was clicked. I then add the new Tab based on the LB that was clicked like this:
[Code]....
This properly adds new Tabs to the TabContainer using this code:
[Code]....
but I still have the issue where I can only ever have one dynamically created tab in the TabContainer at a time. All of the code above is being executed in OnInit, which I thought would save the tabs during post-backs, but instead this is behaving as tho I was adding the tabs in the OnCommand event of the Link Button...
I'm passing a List to an MVC view and generating checkboxes for each object in the list (The checkboxes are named t.Name).I'd like to be able to tell which checkboxes were checked once the form is posted. However, I'd like to avoid using the FormCollection object.
View 1 RepliesMy problem is:
I've got a table, dynamically created, fill with a lot of dropdownlists witches IDs are dynamically created.
When a button is pressed, I need to scan all controls in the table and save their value.
But after the postback I can't no longer access to the table.
I have a script which creates a dynamic textbox (and more) in an AJAX async post back. But when I try to acess the textbox I am told "Object reference not set to an instance of an object". I have been strugleing with this for a long time. This is written in C# .Net 4. The line causing the problem is the very last one where I have tbGameName.Text.Trim()

I add HTML and tags to Page dynamically. But after every postbost, all values are empty. What can I do for Solve?
View 2 RepliesI dynamically create gridview, and in this grid I have template field also
field.HeaderTemplate = New GridViewTemplate(ListItemType.Header, col.ColumnName)
field.ItemTemplate = New GridViewTemplate(ListItemType.Item, col.ColumnName)
grdEmpty.Columns.Add(bfield)
but when enter some value in text box in this template field i lose value on postback. And also on postback I lose all template field and i must re-create this grid.
My goal is: I have button and i want to add new row in this grid, but i want to have old value also.
I have a couple of RadioButtons that are created dynamically. But after postback they don't retain their checked property. I also have some CheckBoxes and they work just fine using the same mechanism (code below). I have narrowed down the problem to the "GroupName" property. If I remove it, it works just fine. But I need the RadioButtons to be mutually exclusive.

So I have two UpdatePanels. I am dynamically creating server-side buttons in UpdatePanel2. When the buttons come out, they are not hooked to the asynchronoustriggers of updatePanel1.
So how can I dynamically add these triggers of these newly dynamically created buttons so that clicking these buttons will only cause a partial postback to UpdatePanel1 ? Right now, when I click these buttons, it causes a partial-postback refresh to UpdatePanel2 (the panel itself that which the controls reside in)
I have a small form with some static elements that I am able to access with javascript the bring up a popup. 4 textboxes are generated and attached to a updatepanel. I've been trying various methods of validating the contols without generating postback.
I found anytime i registered a javascript to the scriptmanager the page must refresh.
Is there anyway it can be done?
I created a templatefield programmatically and it works fine but whenever I clicked the button inside the gridview and do the postback my templatefield are gone.
View 3 RepliesIn design time I created a Gridview and a delete button in a page test.aspx:
[Code]....
The program stopped at statement "if ((row.Cells[COL_INDEX_SELECTED].Controls[0] as CheckBox).Checked)",
because it cannot find the checkbox created before.
I tried to shift all the code in Page_Load to Page_Init, but the ticked checkboxes are still lost.
I could find the ticked checkboxes names in its request object parameters(this.Request.Params.AllKey) if I setup a breakpoint on the error statement.
Does anyone konw what's happening and how to retrieve the selected rows?
I need to access the controls dynamically created template fields at run time in datagrid in post back event. Is there any way to retrieve the values in post back event? Or else give the ideas to acheive my requirement. I need to create no of rows and columns as text box as per user input. After fill the values to text box , i need to access the values in submit button.
View 1 RepliesI have a grid view that is dynamically created.In which every cell in the girdview has a 2 textbox (cTxtboxQty,ctxtWorkOrder) and 2 label.
When user click on the cell, a pop up come out and user are able to change the text inside the cell and click save.After that the pop up close and changed data immediately reflected on the screen.
My problem is:
After my data are changed and updated to database on the pop up page and having it post back to the parent page , my dynamically created textbox in gridview retain old value even new value has been assigned to it.
This sound very weird but i have no idea how to solve this.
My client side code is as below :

I have tested many times and find out that it might be the page hold the old value in memory, so that even we have updated the textbox value, after postback, it still keep and show the old value?

I need to have a Repeater with the letters of the Alphabet, when the letter is clicked on it returns all the "names" that start with the corresponding letter in a gridview.
I have got a basic repeater below working but when I tried to change it to a LinkButton I seem to have problems with the CommandArgument.
<asp:Repeater runat="server" >
<ItemTemplate>
<%# Container.DataItem %>[code]...
I have seen some close examples of this in C# but I need it in VB and the converter I use says incomplete snytax.
