I am creating a LinkButton programmatically and render its HTML output into a Literal control:

The LinkButton appears in the page output, but is not rendered clickable. In the output HTML, the result looks like:

I need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. I´m looking into doing this with button fields right now but I´m curious on how this can be accomplished?

I have a simple question that I can't seem to get... I have a linkbutton on my page... I want to make the text to this linkbutton viewable.. however I dont want the linkbutton to be clickable... It should only be clickable if the user is logging in and in the right role... Is there a way to do this outside of enable="false" ? my client does not like the faded text.. they want the text like the rest on the page.
View 18 RepliesI don't know if this is a bug or whatever, but how can I call the event in the code-behind after enabling the linkbutton?
This is my linkbutton:
<asp:LinkButton ID="btnStartImportNow" runat="server" OnClick="btnStartImportNow_Click" Enabled="false">
<div class="css_action_item_enabled" style="float: right;">
<div class="css_action_item_icon_add">
</div>
<span class="css_action_link">
<asp:Label runat="server" ID="lblStartImport">
</asp:Label>
</span>
</div>
</asp:LinkButton>
Now I have a javascript with this rule:
document.getElementById(clientId + "_btnStartImportNow").disabled = false;
Well the button enables, but I cannot click the button..
There seem to be about a zillion posts on similar situations, but I can't seem to find an answer in any of them. I've tried numerous techniques that I've seen, but nothing is making a difference. I have a Master page with an UpdatePanel with a ContentPlaceholder. In the content page I have a calendar. Above the calendar are LinkButtons that trigger a Command event to switch between Day Week and Month views. In the calendar DayRender event I am adding items to each day of the calendar. Items are pulled from a database. All items are contain within a dynamically generated div to help with layout. Each event that is added is a hyperlink that takes the user to a page where they can edit details of the event.
If there are more than 4 events, I'm adding a LinkButton with the text, "(more...)". I'd like that to trigger a Command event so that I can switch to the Day view of the appropriate day:
[Code]....
The problem is that, while the anchor tag gets generated with the proper text and ID, no href attribute is rendered and, as a result, nothing happens when you click "(more...)". I've tried switching to a Click event, but it does the same thing. (And I need the Command event to use the code I already have in place for some other buttons.) I've tried rendering it as an asp:Hyperlink and using ClientScript.GetPostBackClientHyperlink. That gives me a hyperlink, but I don't know how to get it to trigger so it results in the server interpreting it as a Command event and linking it to the proper event handler.

I have a placeholder that I'm adding a dynamic table to.In one of the cells of the table, I'm trying to add a LinkButton with an OnClick event.
The LinkButton appears fine, but when I click on it, nothing happens.
Here is my code. The table gets created on Page_Load.

I have a link button let's say LB1Â 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 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

I feel like a neewbie for this question but I can not make my linkbutton to trigger when created from code behind.What am I missing here?

I get the ClientID of a control in ItemCreated event like this: 'ctrl0_spanLoader'
and when it is rendered like this (from view source of IE): 'CtlCategory1_ProfiledBasedSearchResult1_ListViewSearchResult_ctrl0_spanLoader'
This happens in Asp.Net 4 and I have no problems in Asp.Net 3.5.
How do I get the real clientID from ClientID property of my control? Is it a matter of configuration or anything else?
There it is written that controls should be added in Init event rather than Load event for the added controls to participate in the Postback data processing.But whose Init or Load event ? Page's Init or the containing container's Init event?
View 3 RepliesI have a form that does a loop to create checkboxes. Here is the code in the loop:
LeftPosition+=120;
cbxDrives.Top = TopPosition;
cbxDrives.Left = LeftPosition;
cbxDrives.Text = d.Name;
CheckBox cbxDrives =
new
CheckBox();this.Controls.Add(cbxDrives);
This creates multiple check boxes on the form, and this works fine.
However, in the code behind for my button that the user clicks to execute the form, I cannot figure how how to read the values for the checkboxes. I've tried:
foreach (CheckBox cbxDrive
in cbxDrives)
{
}
but cbxDrives is not recognized.
I need to read through all of the checkboxes to see their values, so that the appropriate actions can be performed in the code behind.
i wrote following code to create a linkbutton programmatically, but its showing like lable at runtime not as link
Dim lnkbutton As LinkButton = New LinkButton()
lnkbutton.ID = "HostelsClub" & dr("dshotelid").ToString()
lnkbutton.Text = "HostelsClub"
lnkbutton.PostBackUrl = Request.Url.ToString()
lnkbutton.ToolTip = "Click here To Book"
AddHandler lnkbutton.Click, AddressOf lnkBook_Click
PHbook.Controls.Add(lnkbutton)
I'm trying to manually create a button and add a Click event handler for it in code. However when the button is clicked the event handler doesn't seem to react on event (or event isn't called).
we tested the code in Visual Studio 2008 and everything worked just as it should. And I'm using Visual Web Developer 2005 XE. So I assume that I'm missing something to be done manually being in VWD 2005 XE, or the problem is in VWD 2005 XE it self.
here is what I'm doing:

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 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 an internal web search on my website. Previous, it has been used to search by our partnumber only. This was nice and easy
SELECT * FROM View_ProductRange WHERE PartNumber LIKE '%'+ @Search +'%'
I have now built an internal search.
[Code]....
However, I can't use paramaters because the paramaters appear to be 'applied' after the SQL statement has been built, so it would only add the final word the customer searched for due to the paramater taking the final variable at the end of the Foreach Loop. e.g.
[Code]....
Is there 1) a better way to search and 2) a safer option/method/approach.
FYI, at the moment I have
strSearch = strSearch.Replace("'", " ");
strSearch = strSearch.Replace("drop", " ");
strSearch = strSearch.Replace("table", " ");
strSearch = strSearch.Replace("Insert", " ");
strSearch = strSearch.Replace("amend", " ");
strSearch = strSearch.Replace("apend", " ");
strSearch = strSearch.Replace("delete", " ");
strSearch = strSearch.Replace(""", " ");
strSearch = strSearch.Replace("--", " ");
strSearch = strSearch.Replace(""", " ");
but I don't like that (there is a ToLower() method used)!
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.

I am using Javascript to create dynamic controls on the page I am not dealing with File Uploads, just creating custom field things.
I think I need to override SaveViewState and LoadViewState events to keep my controls in the ViewState.
Say I am creating a Textbox in the codebehind of a page like this:
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
TextBox test = new TextBox();
test.SkinkId = "MySkin";
placeHolder.Controls.Add(test);
}
and in my skin file I have this:
<asp:TextBox
runat="server"
SkinId = "MySkin"
Width="400"
/>
Why is the skin not beeing applied to the control. If i declare the control in my aspx page it works ok, but if I try to do it programatically it does not work...
Is it possible to access the html markup of programmatically created controls, and if so, how?

I need to generate a button way after the page loads but I can't work out how to deal with the Event handler. If I do this when the page loads as shown bellow it works as intended but if I use the exact same method in a button it fails. (it creates the button but when I click the button it just disappears instead of showing a msgbox."I know I shouldn't use Msgbox in a web form but I only do it as a test then remove it"
Code:
Partial Class Default3

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim mybutton As Button
mybutton = New Button
mybutton.Text = "Submit"
