I 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.
As you can see, nothing special; just colors and beautiful things.
I click on the blue Edit button and it fires the OnClick postback just fine.... in Chrome! But if I do the same in IE8, it just does nothing; doesn't even detect a click.
I removed the tag and kept just the word "Edit", and it works just fine in IE8 as a simple underlined link; the postback fires.
So, Why can't IE8 accept anything within LinkButton?
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 one Datagrid with Footer. Footer Row Contains Input fields with one Button to add New Values. I have button click event but not getting fires. my code follows:
I have a page with two ajax toolkit popupcontrol extenders, both have a Linkbutton inside the popup window, which is inside a panel and updatepanel. The difference is the second one (Linkbutton2) is inside a Gridview, which is also inside a Updatepanel.
The first one works fine, but the second one does not fire when click on it. The code is as follows:
I've been looking at google for the past few hours, trying to find an issue to a apparently simple problem. I have a UserControl named RolloverLink that basically contains a asp:LinkButton and a <img /> . I tried setting the OnClick handler like this:
[code]....
I put a breakpoint in the propagate method, but it doesnt stop there. The page does post back (it flashes), but the event doesn't get called.
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.
When the user selects an "account" we dynamically create a linkbutton with the selected dates. However, the linkbutton onclick handler doesn't fire when the button is clicked.
Dim linkBtn As New LinkButton linkBtn.Text = "blah" AddHandler linkBtn.Click, AddressOf linkButtonHandler linkBtn.ID = panelDatesRencontre.Controls.OfType(Of LinkButton).Count panelDatesRencontre.Controls.Add(linkBtn) ScriptManager1.RegisterAsyncPostBackControl(linkBtn) Dim Trigger1 As New AsyncPostBackTrigger Trigger1.ControlID = linkBtn.ID Trigger1.EventName = "Click" UpdatePanel2.Triggers.Add(Trigger1)
Answer: i make that in page_load, it seems to work
I have a button which has a click event but its not firing on the first click. I suspect its something to do with that i am in dropdown box control so when i click the Button the event for the dropdown box occurs (textChanged) but it forgets about the click event
Of course if i click it a second time it works.
Or if i click somewhere else first so that the event TextChange occurs and then click the Button the first time it executes..
Is this normal and what are more workarounds if any?
basically the TextChange event must fire but the button click event must fire as well.
All the events i am talking about are ASP.NET events.
here is some examples of the events i am using - both the button and dropdown
uxGetData is a button and uxToDate is a dropdown box
lets say I have a control with a button in it. I want to use my control on a page but then know when the button in the control has been clicked. I assume I need to fire some sort of event when the user clicks the button and then in my parent page I can hook into onMyCustomEvent or something..
i use require field validator in a textbox and it is working fine when i first time click in thr button. but problem is when i use autocomplete extender and fetch some related record and then when i try to click submit button,that time requirefieldvalidator not working.an javascript error occure "object is null in controltovalidate"
Example I have unsubscribed (is want to clear off the previous subscribed event) and subscribed the events every time when dataobject value has assigned:
_dataobject.OnQueryOpen -= new DataObject.On_QueryOpen(RefreshIGrid); _dataobject.OnQueryOpen += new DataObject.On_QueryOpen(RefreshIGrid);
But, the RefreshIGrid still fired depend on how many times my dataobject has been assigned.
is it not really unsubscribed on what I have -= from the begining?
