I've an UpdatePanel where according to operations inside of this UP is filled. I've add some buttons but the buttons to not fire clicks. I've used the code
Button b = new Button();
b.Click += new EventHandler(ClickMe);
...
void ClickMe(object sender, EventArgs e);
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)

I have a LoginView element in an Update panel and use JQuery to hide the div containing the update panel when the cancel button(Html) is clicked.
It works fine normally. However, when I enter an invalid password and there is an error message displayed, the Javascript attached to the Cancel button click stops firing.

I am using UpdatePanel ---> LinkButton --> Div --->Table Structure.
When I click the Linkbutton the div has to show the table format first and has to execute the code in its OnClick event, the problem I am facing is I've tried so many jquery functions shown below:
<asp:LinkButton ID="lnkbtnUnitAdd" runat="server" OnClientClick="Toggledivs()" OnClick="lnkbtnAdd_Click" Text="Add" ></asp:LinkButton
trying to display the div (in updatepanel) while button 'btnDisplay' is clicked. And disappear when clicked second time.
if (!Page.Ispostback)
hideandshowdiv(false);
looking for the proper onclick event code.

I just can't catch the click event of the button.
I have two update panels and in the second update panel i have asp.net button and onclick of the button in codebehind i have disabled it like btnAddSecurity.Enabled = false;
When I disable the button i enable a cancel button before it and on cancel button when i try to enable the btnAddSecurity.Enabled = true it simply doesn't work. Both of my updatepanels updatemode is conditional. what is the problem?
I have a master page containing a ScriptManager control, and a Content Page containing a ScriptManagerProxy Control. Further on the content page I have an UpdatePanel control containing a GridView control and a server side button control. I have registered the button control as a trigger with the UpdatePanel control asynchronously and have set the UpdateMode of the UpdatePanel to "Conditional". I also have a "JumpLoader" control which is outside the UpdatePanel control. I have the following event for Jumploader wired up through Javascript. I am pasting the relevant sections of the code below:

im using an update panel and my web form consists of textboxs and combo box, my problem is that when i click the button save for the first time, my page simply postbacks and the event save wouldnt fire, click it the second time and poof save will execute.. I notice that it is caused by my dropdown box and textbox autopostback function, i need to set this to true since i need to execute another function that will disable the dropdown when the textbox is filled and vice versa,set this to false and save will function normally..any ideas how to fix this?
here is the code for that.
<asp:DropDownList
ID="ddNewLocation"
runat="server"
Width="95%"
AutoPostBack="true"
AppendDataBoundItems="True"
onselectedindexchanged="ddNewLocation_SelectedIndexChanged">
<asp:TextBox
ID="txtNewLocation"
runat="server"
Width="90%"
AutoPostBack="true"
ontextchanged="txtNewLocation_TextChanged"></asp:TextBox>
In my default Page I register this listener:

and this Event is never fired

I've a dropdown and a listview inside an updatepanel (Master/Child relationship) so based on value selected in dropdown the listview gets populated. The Listview allow user to perform Edit/Insert/delete of records. I have to implement a scenario when a user is editing/inserting a record and if he tries to navigate away/change the value in dropdown he should be prompted to save the data and if he choose yes in JS Confirm Dialogue then the currently edited/inserting record should be saved (for which i'm trying to mimic the click of the update/insert button using js). I've attached change eventhandler of dropdown using JQuery which is getting called properly bind.
[Code]....
This code gets bind using
Sys.Application.add_load(saveChanges);
I also tried the following
Sys.WebForms.PageRequestManager.getInstance().add_initializeRequest(saveChanges);Sys.WebForms.PageRequestManager.getInstance().add_endRequest(saveChanges). The eventhandler gets called correctly but the click() doesn't work! Also the reason I'm calling click() method of button is to perform the validations via RequireValidator/RangeValidators.
I'm attempting to set the visibility my UpdatePanel to true upon a button click event (as shown below). It should be rather straightforward but unfortunately it's not working at all. Any idea why it's going wrong?
//Markup
<asp:UpdatePanel ID="UpdatePanelSearchSubject" runat="server" UpdateMode="Always" Visible="false">
<ContentTemplate>
<p>
</p>
<p>
<asp:TextBox ID="findSubject" runat="server" Width="248px"></asp:TextBox>
</p>
<asp:RadioButton ID="peopleSearch" runat="server" Checked="True"
Text="People" GroupName="searchSubject" />
<asp:RadioButton ID="groupSearch" runat="server" Text="Group"
GroupName="searchSubject" />
<br />
<asp:Button ID="btnGetGroups" runat="server" Text="Search"
OnClick="btnGetGroups_Click" BackColor="#CCFFCC" />
<br />
<br />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSearchSubject" />
</Triggers>
</asp:UpdatePanel>
//code behind
protected void btnSearchSubject_Click(object sender, EventArgs e)
{
UpdatePanelSearchSubject.Visible = true;
}
I'm using a searchoption on my website. (language = VB)
The user can choose a searchcriteria out of a dropdownlist (Artist name, Description, Price, Genre, Type) . If the user selects one of the options in the dropdownlist the correct textboxes are shown.
For example: if the user selects Price he gets two textboxes (one for the min price and one for the max price) if the user selects Artist Name he gets one textbox
The dropdownlist and the textboxes are put into an updatepanel. The searchbutton is outside the updatepanel.
Now for the problem:
If the user doesn't fill in a textbox and presses the searchbutton, the backcolor of that empty textbox should be turned red. The searchbutton is set as a trigger and the panel is updated on the buttonclick, but the colors don't show.
In the clickevent of the button I've said the following code:
If txtCriteria.text = "" then
txtCriteria.backcolor = Red
Else
txtCriteria.backcolor = White
End if
Quite a simple piece of code. This works if I remove the updatepanel from my page, but I'd like to keep the updatepanel because it's really nice :p.

I have an update panel that has a timer set as the AsyncPostBackTrigger.In this Update Panel I have a repeater and in the repeater I have a few buttons which have on click events.The on click of these buttons does not appear to fire until the timer has tickedI have tried debugging and this is what seems to be happening, either way it takes ages for the button click to actually fire.
