.net - JQuery Click Disappears Into Some Abyss?

Nov 11, 2010

Here is my setup: I have an asp.net button on a page --

<asp:Button id="btnSelectEmp" runat="server" Text="Select Employee" />

I have a .js file with the following jQuery click event --

$("input[id$='_btnSelectEmp']").click(function ($e) {
$("div[id$='_divEmpSearch']").css("display", "inline");
$e.preventDefault();
});

As you can see, clicking upon the button will set a div visible. Nothing special; not rocket science. The div is wrapped with an asp.net update panel, and it contains an asp.net user control (.ascx)

<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<div id="divEmpSearch" runat="server" style="display: none;">[code]....

The button in the user control that does a postback is working great. I click it, a postback occurs and my div control is re-hidden. I can then click on the Select Employee button (the one that I supplied the code for at the very first of the question) and the jQuery click event is handled and the div will be reshown.However, the button in the user control that does an asynchronous postback works also, but after it hides the div, if I then click on the Select Employee button the jQuery click event will not be handled.What this tells me is that for some reason during an asynchronous postback to the page, something happens to the Select Employee button so that the jQuery click event no longer happens. Why?

Information Disappears On Button Click?

Jul 13, 2010

I have a ListView that has a FileUpload control and a button in each ListViewItem. I have an OnClick event on my button where i try and pull information from the FileUpload control, but when I try to access the control all of the values that were set are gone (FileName etc).

What do I need to do differently here to access the information I just entered?

<asp:ListView ID="lv_Uploads" runat="server" OnItemDataBound="GetThumbs" EnableViewState="true" >
<LayoutTemplate>
<div id="itemPlaceholder" runat="server" />
</LayoutTemplate>
<ItemTemplate>
<div style="width:500px;>.......

Code behind:

protected void SaveFile(object sender, EventArgs e)
{
//This always evaluates to an empty string...
string myFile = ((FileUpload)((Button)sender).Parent.FindControl("fu_Upload")).FileName;

Search GridView Disappears On Navigate Button Click?

Jun 22, 2015

On my Form I have 2 gridviews namely; gvCRSearch (that displays search results) and gvCRView (that displays all the change requests raised).. Now, when the records are more than 10 in gvCRSearch it automatically creates a navigation number i.e., 1 2 3 Same thing happens to gvCRView

What is wrong is that when I click the navigation i.e., ( for example 2) on gvCRSearch

1) the gvCrSearch becomes visible = false

2) the gvCRView if it has a navigation number is moved to 2

So the effect is seen the next view (gvCRView) and the gridview (gvCRSearch becomes invisible)

the asp is as shown;

Code:
<asp:GridView ID="gvCRSearchView" runat="server" ShowHeader="True" AutoGenerateColumns="False" DataSourceID="CRSearch"
BackColor="White" BorderColor="#600000" BorderStyle="Solid" BorderWidth="2px" CellPadding="3" Font-Size="89.5%"
ForeColor="Black" GridLines="Vertical" AllowPaging="True" PageSize = "10" AllowSorting ="true" CssClass = "MainGridView">
<Columns>

AJAX :: Chrome Update - Toolkit TabContainer Disappears On Button Click.

Sep 10, 2010

Yesterday (Thursday Sep 10th 2010) I was happy to have a TabContainer working fine on a simple page as im learning to use it.

On the page was:

1) Ajax Script manger.
2) 1 command button (it would make label1.text = "hello world"
3) A Ajax TabContainer with 2 tabs...
4) Label1

That was it and it was working fine in Chrom and IE Woohoo.. I go home...

This morning I load it up to keep working way and doing more with it.... Chrome is my default browser, it loads and I click tab2 then tab 1 all is well.... I click Butto1 and the hole TabContainer disapears..

After much dinging I find it still works in IE but that my Chrome has updated (on its own): (I notice only one ICON in Chrome in the uper right corner by the addres bar... Only the Wrench ICON, No more Page ICON.. So I check and sure enough Chrome did a push to V 6.0.472.55.. Anyhow thats the difference and now TabContainer goes poof/disappears when clicking a button that refeshes the page.

Forms Data Controls :: GridView Disappears When Click A Column Header To Sort?

Jul 28, 2010

I have a page with a TextBox, a Button, a GridView, and a SqlDataSource. I click the Button to execute the SQL in the TextBox using the SqlDataSource. The SqlDataSource populates the GridView. Everything works as expected until I click a column heading to sort.

When I click a column heading, the GridView disappears and I have to click the Button to display the grid again. When I do, the grid is displayed in the order of the column I clicked.

I don't understand why the GridView is disappearing when I click a column header.

Does anyone know how to fix this so the GridView is sorted and displayed only by clicking the column header?

JQuery :: Update Panels - Functionality Disappears Using Document.ready()

Mar 24, 2011

I have a problem with JQuery when using update panels. My page is structured like this:

Text search
Login Update Panel
Login form
End of Login Update Panel

For clarity I have remove all other page objects. As you can see the login form is inside an update panel, the text search is not. Both of these objects rely on jquery to function correctly (assuming javascript is enabled). In order to persist the functionality after postback with the login form, I use the PageLoad() function. This works ok.

I tried the same with the text search but it doesnt work. I presume its because it isn't inside the updated update panel. At the same time the functionality disappears using document.ready() and I can't understand why it works with neither rather than one or the other.

I need this to work without JS as well, which is why I still generate the HREF on the links, so I'm just intercepting the click and then invoking the parent click which in turn toggles the accordion header.

This works in IE but no Firefox, Chrome.

Force JQuery Click Event To Proceed Any Control Click Event On Page?

Mar 22, 2010

I've found posts about making a click event with jQuery for a button, however I need a little more then that. When any postback occurs on a page, I need to fire off a jQuery click event. Based on a condition, I want to continue processing (including running the server-side event code after the jQuery code), or, perform a redirect. I'm not quite sure how to go about this.

JQuery :: Checkbox Click Event Problems When Using JQuery Safari Checkbox Plugin?

Nov 26, 2010

my page are 1 checkbox and 1 hidden label and 1 hidden panel. With the help of forum member raghav_khunger I've managed to write the code which shows panel and label when checkBox is checked. I've also added the code which is checking on every page post back the status of checkbox and hide/show panel and label appropriately. This is working fine.However when I add jQuery Safari checkbox plugin [URL] problems appear.

Looks like the code which is handling click event is doing reverse thing: when panel and label should be hidden are shown. I can change this but then there would be problems because of the second part of the code which is checking checkbox on page load. So when I check the checkbox nothing happens. I must uncheck it and label and panel appears. But if panel is uncheck the label and panel would be hidden because on next page load (when user clicks button next).As I said before the same code is working fine and it's test in all browsers (IE,FF,O,S,C). Maybe there is problem with checkbox plugin since it's in beta version.
