Edit CommandName On LinkButton Using Javascript?
Oct 6, 2010
I have a series of link buttons in a repeater that switch pages
<asp:Repeater ID="rptPageLinks" runat="server"><ItemTemplate>
<asp:LinkButton ID="lnkNewPage" runat="server" Text='<%# Eval("Page") %>'
OnCommand="SomeEventHandler" CommandArgument='<%# Eval("Page") %>' CommandName="Redirect"
OnClientClick="return confirm('Do you want to save your chanes before you navigate to a new page?');" />
</ItemTemplate></asp:Repeater>
What I want to be able to do is pass the result from the OnClientClick into the EventHandler, ideally by changing the CommandName (i.e. if they click 'yes' on the confirmation it changes the CommandName to "SaveAndRedirect", if they click 'no' it stays as 'Redirect').

the structure is like this:
Grivdivew
ItemTemplate
PlaceHolder
/ItemTemplate
/Gridview
And then I try to add some dynamic controls into the placehold control from code behind, I use the RowDataBound Event
Private Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
Dim ph As PlaceHolder = CType(e.Row.Cells(1).FindControl("PlaceHolder"), PlaceHolder)[code]....
The problem is the button CommandName is not functioning. And more strangely, if I add the button manually into the placeholder, like this:
Grivdivew
ItemTemplate
PlaceHolder[code]....

I have a radcombobox in radgrid nested inside FormTemplate:
Code:
<telerik:RadComboBox Skin="WebBlue" Width="250px" Height="150px" runat="server"
ID="TitleCombo" OnDataBound="Title_DataBound"
SelectedValue='<%# Bind("Title") %>' AppendDataBoundItems="true"
OnSelectedIndexChanged="Title_SelectedIndexChanged" AutoPostBack="true" />
then i insert an item to the top of list (at zero index):
Code:
protected void Title_DataBound(object sender, EventArgs e)
{
var item = (RadComboBox)sender;
item.Items.Insert(0, new RadComboBoxItem("Select title...", "0"));
}
It works perfect but, IF the Title field is zero and you Click EDIT LinkButton it throws an exception: Selection out of range Parameter name: value I would say that it's expected as zero index does not exist at the moment when i click edit button. I bind the combo from within RadGrid1_ItemCreated event.

In the below code, when we define the parameters CommandName="Insert" is it actually the same as executing the method Insert? As I can't find Insert anywhere...
<div class="actionbuttons">
<Club:RolloverButton ID="apply1" CommandName="Insert" Text="Add Event" runat="server" />
<Club:RolloverLink ID="Cancel" Text="Cancel" runat="server" NavigateURL='<%# "Events_view.aspx?EventID=" + Convert.ToString(Eval("ID")) %>' />
</div>
I have the following SqlDataSource as well:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ClubSiteDB %>"
SelectCommand="SELECT dbo.Events.id, dbo.Events.starttime, dbo.events.endtime, dbo.Events.title, dbo.Events.description, dbo.Events.staticURL, dbo.Events.photo, dbo.Events.location, dbo.Locations.title AS locationname FROM dbo.Events LEFT OUTER JOIN dbo.Locations ON dbo.Events.location = dbo.Locations.id where Events.id=@id"
InsertCommand="INSERT INTO Events(starttime, endtime, title, description, staticURL, location, photo) VALUES (@starttime, @endtime, @title, @description, @staticURL, @location, @photo)"
UpdateCommand="UPDATE Events SET starttime = @starttime, endtime=@endtime, title = @title, description = @description, staticURL = @staticURL, location = @location, photo = @photo WHERE (id = @id)"
DeleteCommand="DELETE Events WHERE id=@id" OldValuesParameterFormatString="{0}">

<asp:Parameter Name="id" />
</InsertParameters>
<DeleteParameters>

I want it to insert using the InsertCommand, however when I do SqlDataSource1.Insert() it's complaining that starttime is NULL

I want to allow users to click only once on button. In fact, the button is a user control:
[Code]....
That button control gives us access to OnClientClick property of lbButton. This button is used on other user control:
[Code]....
As you can see - i disable button on client-side and then return true (to do a postback). That's for only sample purposes. This code will disable my button but there will be no postback. If leave only "return true;" inside onclientclick script then i'll have my postback. The conclusion is - i can't do a postback if i disable button. The question is what's the reason of such behaviour and can i do any trick to over overcome this issue. I figured out i can hide button and still perform postback. But why it can't be disabled? There was already a thread on similar topic : [URL] but answers weren't satysfying. User Participant gave his solution there but i'm not fully understand his idea. Could someone explain to me why it can't be done my way and if it can be done by any other method?

I have a little problem with a LinkButton in a UserControl based asp.net application. In Firefox, one single click on the LinkButton does not do anything. You have to press and hold the LinkButton for approx. 800ms to successfully trigger the PostBack.The Focus outline is lagging too. When i click on that LinkButton, the outline-change needs approximately the same amount of time you have to hold the button the trigger the postback. the webapplication and the LinkButtons are working perfectly in IE and Chrome the javascript libraries (external and internal) are currently neither obfuscated nor compressed Here's the asp.net markup:
<li id="liMemberGetPerson" runat="server" class="inactive clear">
<div class="tab clear">
<div class="tab-left"></div>
<div class="tab-main">
<asp:LinkButton ID="lbPersonArea" runat="server"
Text="Person" CausesValidation="false"
OnCommand="OnMemberViewAspectChange"
CommandArgument="MemberGetPerson" />
</div>
<div class="tab-right"></div>
</div>
</li>
Edit: the "code-behind":
protected void OnMemberViewAspectChange(Object sender, CommandEventArgs e){
AppAction currentAction = HistoryManagerFactory.GetCommandManager().GetCurrentCommand();
AppAction newAction = new AppAction();
newAction.ViewType = ViewType.MemberView;
newAction.AspectType = (AspectType)Enum.Parse(typeof(AspectType), e.CommandArgument.ToString());
newAction.ObjectID = currentAction.ObjectID;
newAction.Mode = currentAction.Mode;
HistoryManagerFactory.GetCommandManager().AddNewCommand(newAction);
ChangeAspect( newAction );}
The ChangeAspect() method call renders the corresponding View ( UserControl ). I have tried the following without success: Disable the Firefox Client Caching Disabling PartialPage Updates (disabling the UpdatePanels) If anyone has ever encountered this problem, i'd be very thankful to hear about any possible solutions.

I built a simple user control called noteEditor. I need to set/get the CommandName property when the control is used in a gridview. I seem to be able to set it just fine but when I to get it I get a null.Here is the code for my user control:

Here is how I use the control in a gridview on the host page:

So, I have a MasterPage, in which I have an ImageButton and an UpdatePanel. Inside the UpdatePanel I have a LinkButton.
[Code]....
As you can see, both components are asociated to the same OnClick event, which should open said PDF document in a new window using javascript (Code Behind of the MasterPage):
[Code]....
I build the path using the toolTip of the component that has been clicked,which has the name of the file that should load in the
new window.
When I run the application, and click the ImageButton, the new window opens and the file loads correctly. However, when I click the LinkButton, nothing happens (it should do exactly the same as the ImageButton).
If I set a breakpoint, and debug, when I click the LinkButton, it goes to the LnkRelease1 event (as it should), everything looks fine, but it doesnt open the new window, It doesn't execute the javascript window.open.

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...

I've turned up lots of advise from similar things, but not this exactly. I have a gridview with a templatefield that I want to call javascript from the OnClick event (or OnClientClick). When I try to compile, it complains saying my server tag isn't well formed. I'm sure that's a red herring...

i got this inside a button inside a datalist
CommandName="<%# Container.ItemIndex %>"
when i click the button, i'm expecting commandname to = 0, then 1, then 2, etc, as the datalist progresses, and i'm using that value in the button click's c#but i'm getting this error, i'm pretty sure i'm using this exact setup on another page and i have no problems, any idea what's going on?Server Error in '/' Application.

Is there a way to change the values for these two attributes on the client side and have it reflected on the server side after the postback. I tried it but it does not seem to work. I wanted to have one button on the page that I would delegate submits too, and assign these two arguments on the client side. Seems like not possible. Assuming there is a button named "cmd" in the form
<script type="text/javascript" language="javascript">
$(document).ready(function () {
$("#<%=cmd.ClientID %>").click(function () {[code]....
If one checks the value after postback they are still the same as they were before postback.

The DetailsView control has in its
Events an
ItemCommand event that uses the
DetailsViewCommandEventArgs event arg class which has a
CommandName property.
My questions are...
What are the possible values (e.g. "Select", "Insert", etc.) for this CommandName property when operating a standard, uncustomized DetailsView control?
Which order do the following fire in?
ItemCommand
ItemCreated
ItemDeleted
ItemDeleting
ItemInserted
ItemInserting
ItemUpdated
ItemUpdating
The "ing" events are currently being intercepted so that if the user doesn't have permission I set the e.Cancel = true and the "ed" events have redirects to send the user back to a list page that shows the items they just added/updated/deleted. However, I am not able to capture the Cancel button on the DetailsView control since there's no event for it. What I want is to redirect the user back to the list page if they click on Cancel as well.

I have a repeater that has a LinkButton in the Item Template. The LinkButton displays a UserControl that consists of a FormView. The UserControl has an HTML Element that when clicked hides the UserControl by simply change the display of the control from 'block' to 'none'. If the 'Close' span is clicked, the UserControl is successfully hidden, but afterward, the 'Edit' linkbuttons no longer postback.

I have a GridView with a couple of buttons (asp:Button) in it (last row). Both of them have a CommandName attribute on them and this is handled server side in a grid_RowCommand event handler. Now, this works fine. However, I need to add client side code (Javascript/jQuery) to disable the two buttons when someone clicks on or the other. This is to prevent the user from double-clicking and creating potential havoc.
The way I have done this is by adding OnClientClick on both buttons which calls a javascript function that uses jQuery to disable the two buttons. This works fine, it's just that the page doesn't post back and so the RowCommand event handler never fires.

I am building an MVC 2 web app, where I want to display information about something (the parent) as well as child details which are displayed as rows (children have a many to one relationship to the parent).I have implemented AJAX in MVC before using Ajax.BeginForm and partial views Using this method - with minor changes for MVC 2 release.
I want to add the ability to edit child rows inline using ajax, but I would like to know how others implement this. Are there facilities in MVC that can do this?

I'm using DevExpress ASPxGridView edit form, using default edit form. However when I open the edit form in IE6 and click "update" to insert the record, it causes a JavaScript error that says "type" is null or not an object". However it works fine in IE7.

I have Telerik RadGrid with a custom edit form. In my edit form there is a RadDatePicker to which I have added a custom footer template containing a 'Today' button. In the OnClick event of the button I call a Javascript function which takes the control ID to set the selected date. However, because the control is inside the edit form there is no variable created for it and the compiler throws an error when I try getting the client ID. The RadDatePicker is declared with:
<telerik:RadDatePicker ID="ControlName" runat="server" SelectedDate='<%# Bind("Field") %>'>
<Calendar ID="Calendar1" runat="server">
<FooterTemplate>
<div style="width: 100%; text-align: center; background-color: Gray;">
<input id="Button1" type="button" value="Today" class="button"
onclick="GoToToday('<%= ControlName.ClientID %>')" />
</div>
</FooterTemplate>
</Calendar>
</telerik:RadDatePicker>
The error I get is CS0103: The name 'ControlName' does not exist in the current context on the line referencing the ClientID. Is there another way in which to get the ID to pass to the Javascript function?
