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?
Code:

In my user control I have gridview, and this grid is created programmatically, using Itemplate. In InstantiateIn methods I have this code.
Select Case _templateType
Case ListItemType.Header
Dim linkButton As New LinkButton [code]....
I want to wired up Click event to this LinkButton, and use this event in code behind.This is constructor of GridViewTemplate how implements ITemplate
Public Sub New(ByVal type As ListItemType, ByVal colname As String, Optional ByVal infoType As String = "")
'Stores the template type.
_templateType = type
'Stores the column na [code]....
and i have this call from user control:bfield.ItemTemplate = New GridViewTemplate(ListItemType.Item, dt.Columns(col).ColumnName, "label")
where is Dim bfield As TemplateField = New TemplateField()
I have searched around but unable to find a solution that will work. I have a link button that is created dynamically during the page load. It is given an ID (obviously). There is a script manager on the page. I have the controls added to a panel in the updatepanel (updatePanel1). There is a dynamic label that is also created with each link button. I can get a response from the linkbutton click event during a postback on the second time clicking the linkbutton, but I am getting a complete postback instead of the asyncpostback for that control. During the creation of the dynamic linkbuttons, I am also creating a dynamic trigger for each button and adding it to the updatePanel1. The Click event is not firing the method without doing a complete page postback.
View 4 RepliesI have the following Hyperlink as a button:-
<asp:LinkButton ID="loginButton" runat="server" CssClass="loginButton" Text="LOGIN" OnClientClick="return validateLogin(memNoID,pwID)" AddressOf="loginButton.Click"></asp:LinkButton>
It causes a postback but only executes the onload and prerender sections of code. It totally ignores the following function signature:-
Protected Sub loginButton_Click(ByVal sender As Object, ByVal e As EventArgs)
Some code
End Sub
I have a LinkButton within a Datagrid. I am having trouble setting a Click event for it. I will add the OnClick="Remove_Click" attribute in the HTML. But when I go to write the actual event, VB isn't finding the LinkButton. Therefore nothing happens.
Here is the code for it.
<asp:DataGrid ID="StandardsDataGrid" runat="server" ShowHeader="false"
ShowFooter="false"
AutoGenerateColumns="false" CellPadding="2" CellSpacing="0"
ItemStyle-VerticalAlign="middle"
DataKeyField="Id" Width="100%" BorderColor="#000">
<Columns>
<asp:TemplateColumn>
<ItemTemplate>

I've placed a link button control on my web form and added the click event to the code behind automatically), but I've placed a break point and it never hits it. If I do the same thing with a button it works just fine.I've searched for this problem and none of the results seem to answer why mine isn't working. Maybe I'm just missing something?
View 17 RepliesI have made a popup that works within an update panel but what I can't get to work is that it calls the response.redirect to the home page right away instead of giving me the popup box. Is there a way to get around this. I insert my sql to the db, then call the popup but and then want to redirect to home page. but it automatically goes to home page is there a way to stop it until message is seen then redirect.

How can I launch an Outlook email window (similar to what mailto: does in a hyperlink) ?
This needs to be done in a LinkButton click event.
I created a usercontrol I use to build up a list of at runtime. Each instance represent one category, and it will have a title, description and a button taking the user to the page displaying all articles for that category.
The control's members:
Code:
public string Title { get; set; }
public string Description { get; set; }
public int CategoryId { get; set; }
And the markup:
Code:
<h4><a href="#"><%=Title%></a></h4>
<div>
<p><%=Description%></p>
<p>
<br />
<asp:LinkButton CommandArgument="<%=CategoryId %>" runat="server"
CssClass="small btn red fr" onclick="LinkButton_Click">Go To <%=Title%></asp:LinkButton>
</p>
</div>
The code show's just fine, but the click even never fires when I click the button:
Code:
protected void LinkButton_Click(object sender, EventArgs e)
{
var x = sender as LinkButton;
string z = x.CommandArgument;
}
Obviously doing it wrong, but then, did not touch webforms in a long time.

I dont know what happened but none of my buttons or linkbuttons causes a postback anymore. I have dragged a few updatepannels on the page but the linkbutton concerned is not enclosed within an update pannel. when I click it there is just no postback happening anymore. I set the debugger at Page_load but...its not reached. I used firebug to analyse the http requests. there is none. its like those are not considered buttons anymore.
View 5 RepliesI 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

Can i bind and call the user control directly on click event of link button? instead of binding user control in another aspx page and then call it to the masterpage's link button click?
or else can i bind user control in a page lets say default.aspx and then call it in two different master page and show different functionality of it according to the masterpage its getting shown?
I have a gridview where, when the user clicks the row, a modal form is shown and values are passed back to the calling function. This works just fine. However, now I have the requirement that instead of clicking the entire row, they want to just click a link button on the row (not the entire row) and get this same functionality. I am new to JQuery and cannot figure out how to select the link button inside the gridview in order to attach my function to it. Also, once I have that figured out, how do I get values from the Link Button's row to pass to my modal form? Here is my jquery function which works fine for the row-click:
$(document).ready(function() {
// set the background color of selected gridview row
$("#<%=gridResults.ClientID%> tr").click(function() {
$(this).css("background-color", "PowderBlue");

Text="Modal Search" >

I have created a master page for website layout in my project. I have used a linkbutton control to trigger between Login/Logout functionality but when I click on this control the underlying click event handler is not being executed anyway.When I click on this control, the page pointed by its PostBackUrl property is open which should probably occure after its click event hander have been executed.

I have a linkbutton to which i am binding to the click event using jQuery, however the page still posts back no matter what i try...
According to this i should be able to use event.preventDefault However nothing seems to work and it always posts back, but i do get the alert
Here is my example
<asp:LinkButton runat="server" Text="TEST" ID="lnkTest"></asp:LinkButton>
<script>
$(document).ready(function () {
var lnk = $('#<%=this.lnkTest.ClientID %>');
lnk.unbind('click.test').bind('click.test', function (event) { alert("Click"); event.preventDefault(); event.stopPropagation(); return false; });
});
</script>
UPDATE
Okay after some further investigation it seems that this does work as expected when i run it in a standalone page, however we are using this script, and it appears that it is causing a conflict..
That script moves any href='javascript:... into the click handler, im guessing that the order the handlers are assigned may have something to do with it...
how to handle click event of linkbutton in gridview in asp.net
View 2 RepliesThe LinkButton on click event automatically does what I think is called a postback. What line of code do I need to use to invoke this event?
View 3 RepliesI 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.
