I have textboxes, and buttons, that i would like always to be visible on the current page view, that means if by default the textbox is at the top of the page, and if the user scroll the page to the bottom , i would like my textbox to be still visible to the user ( it should automatically scroll with the page). Is it possible to do this? put my textboxe under another control? javascript?
View 7 RepliesI have a form in aASP User Control (.ascx) file. Maxlength does not work for the multiline textboxe hence it is generated as a textarea, which has no support for this attribute. I could maybe use some asp validation, to prevent submission of too much text, but I want to prevent it to be possible to even enter too many characters, just like is possible for single line textboxes... I don't know if the control has any onload event that I could use to add attributes to the textbox from code behind and and combined with javascript fix this or anything..
View 1 RepliesI want to enhance a composite control's client side, my approach is to recreate all method on JavaScript, so here I have some troubles:Can I call onclick event on client side otherwise on server side?the statement table.onclick=SelectRow(event) fires a bug!Code:
function Control_Init() {
if( !(document.getElementById) ) { return; }
for( var i = 0; i < Controls.length; i++ ) {

I think I summed up the question in the title. Here is some further elaboration...I have a web user control that is used in multiple places, sometimes more than once on a given page.The web user control has a specific set of JavaScript functions (mostly jQuery code) that are containted within *.js files and automatically inserted into page headers.However, when I want to use the control more than once on a page, the *.js files are included 'n' number of times and, rightly so, the browser gets confused as to which control it's meant to be executing which function on.What do I need to do in order to resolve this problem? I've been staring at this all day and I'm at a loss.
View 2 RepliesI have the function put here like below:
$(document).ready(function () {
UserControlNameInit();
});
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript">
</script>
However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...
how to find Textbox Control inside DetailsView Control Using Javascript, I tried below but gives an error OBject reference not found
document.getElementById('<%=DetailsView1.FindControl("TextBox1").ClientID%>');
I have written a web usercontrol (ascx). Inside, there is a Panel that I want to show/hide on click of a hyperlink inside the usercontrol.
Normally, this is easy just by doing something like this (the onclick attribute is added to the hyperlink on prerender):
var PanelToShow = document.getElementById('<%=PanelInvoiceHasBeenCreated.ClientID %>');
if (PanelToHide != null) {
PanelToHide.style.display = 'none';
}
but because the ascx control is held within the gridview, the above will assess all the controls (of which there are many in the gridview) with the name 'PanelInvoiceHasBeenCreated'. The only time it will work is when there is 1 row in the gridview. Currently, with my existing code, if I click the hyperlink in any row, it shows/hides the panel in the bottom row of the gridview!
Therefore, my question is how do I get the actual, unique ID I need to show/hide on the correct control in the correct row?
how to set webform control proprieties in asp.net and ajax control using javascript. I have asp page that has checkBox, TextBox, MaskedEditExtender, and RegularExpressionValidator.
I set the mask for MaskedEditExtender as Mask="(999)999-9999" and I set the ValidationExpression for RegularExpressionValidator as ValidationExpression="d{10}".
I want to change these two properties when user checked the international checkbox to: Mask="999999999999" and as ValidationExpression="d{12}" Using JavaScript without interrupting with server side and when the user unchecked they get previous value so the interaction should be only in the client side.

Suppose I have an ASP.NET Text Box as Below :
<asp:TextBox ID="txtQuantity" runat="server" Text="0"></asp:TextBox>
I want to get this box's current value in javascript. How can I access this element? If it was a normal html text box, with id="txtQuantity", then I could access it using "document.getElementById("txtQuantity")". But how can I access ASP.NET text box in javascript?

View 1 RepliesI have a repeater which nests one or more custom control instances. Each custom control instance has a drop down and a button called "Update".
This all works fine when JS is on.
However with JS off, I get the "Invalid postback or callback argument. Event validation is enabled..." error.
Thinking about this, I imagine the following is happening:
ASP.NET creates ViewState for the page. When the page is posted back, the viewstate should be passed back to the page via the js hooks that ASP.NET puts in place. However, because JS is OFF, this isn't passed back. ASP.NET then flags a mismatch between the ViewState that it expects, and the Viewstate that it receives.

I'm moving itmes from one ASP.NET ListBox control to another ListBox control from client-side. It works on the client-side but when I tried to count items in destination ListBox on the server-side, it's always nothing. Below, is the jQuery code used to add/remove items from ListBox control.
[Code].....
I know that we can add/remove items from ListBox from server-side. But I'd like to get it done from client-side. Why there isn't anything in the destination ListBox when counting the items from the code-behind, eventhough the items are added from the client-side already.
Now the weird thing is I have a user control UserControl1 in which I put some JavaScrdipt logic there, and I have another user control UserControl2 and I registered both in the page called Page1.aspx.I would like to call the JavaScript function resided in UserControl1 from UserControl2, however, I got an error saying the function is not defined. I think both user controls are loaded before I use them then I think the JavaScript function can been seen anyway in that page.

I have a UserControl with two labels and a slider control on it. I have a javascript function that is called when the value of the slider changes, and it is supposed to update the text of the labels. The ascx code is:
asp Code:
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="AlignSlider.ascx.vb" Inherits="F1TimeTrials.Controls.AlignSlider" %><%@ Register assembly="Infragistics35.Web.v10.2, Version=10.2.20102.1011, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb" namespace="Infragistics.Web.UI.EditorControls" tagprefix="ig" %> <script type="text/javascript" id="igClientScript"><!-- function sliderControl_ValueChanged(sender, eventArgs) { var leftLabel = document.getElementById('<%= Me.lblLeftValue.ClientID %>'); var rightLabel = document.getElementById('<%= Me.lblRightValue.ClientID %>'); var maxValue = sender.get_maxValueAsDouble(); var value = eventArgs.get_newValue(); leftLabel.innerHTML = value; rightLabel.innerHTML = maxValue - value; }// --></script> <asp:Table ID="table" runat="server"> <asp:TableRow runat="server"> <asp:TableCell runat="server"> <asp:Label runat="server" ID="lblLeftValue" Text="0" /> </asp:TableCell> <asp:TableCell runat="server"> <ig:WebSlider ID="sliderControl" runat="server" ValueType="Double" > <ClientEvents ValueChanged="sliderControl_ValueChanged" /> </ig:WebSlider> </asp:TableCell> <asp:TableCell runat="server"> <asp:Label runat="server" ID="lblRightValue" Text="100"/> </asp:TableCell> </asp:TableRow></asp:Table>
When I put this control on a page it works just fine. I drag the slider, the labels update with the new values. However, I actually need a large number of these controls on my page (around 10-20 I think), and this is where the problems start. When I change the slider on one of these UserControls, it changes the text of only the labels in the LAST instance of this UserControl on the page. It seems that the 'document.getElementById' function actually searches through the entire page rather than just the one UserControl. How can I fix this? How can I get the two label controls from this current UserControl instance, and not any other instance on the page?
How do I get the width of a control in javascript if it hasn't been set by a css file declaration, a Style declaration, or a skinID.
I have tried control.width, control.getAttribute.width, and I get nothing!
