How to get the value of a control set by a client side JavaScript?
I have a textbox that its value is set by a client side JavaScript. How to get its value in server side? I am using the following line of code and it is working fine. Is there a better way?
[Code]....
Also, how to get the value of a control (TextBox) found in a GridView (EditItemTemplate) set by a client side JavaScript ?
I 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.
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...
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?
I have a javascript embedded in my extended gridview control that reference the grid control. Example:
[Code]....
HTML code:

way to determine the gridview object in javascript. I want to make it generic so that if I use this gridview in any other control it should work instead of hardcoding the name.
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.
I have to fullfill a requirement where my activeX control (developed in c#) need to invoke a callback JavaScript function asynchronously (or) synchronously (or) in both ways. I can handle the context using threads. JavaScript:
function handler_1(){ ..... } myActiveXObject.registerCallBack(handler_1);
Where in ActiveX control, I need a function "registerCallBack" to accept the argument. But I have no clue how to invoke that registered JavaScript function from my ActiveX control. By digging MSDN forum, I found something as script.GetType().InvokeMember("myJSFunctionName", BindingFlags.Instance | BindingFlags.InvokeMethod | BindingFlags.Public, null, script, null);
the above line throwing me an exception Unknown Name etc. I do have the definition for "myJSFunctionName" in javascript and I got the script object from the document object.
I have multiple HyperLink controls and I want to enable or disable different panels base on which HyperLink I clicked on. This should be done using javascript. The question is: Is that possible to even use javascript for this? I know other button controls, there is onClick property but not in Hyperlink.
pass name of the textbox Control to javascript function
[Code]....
<script type="text/javascript" language="javascript"> var sum = 3; var textboxObj,ObjName; function validate(textboxObj,ObjName) { alert('Hello'); var arrayOfObjects = document.getElementsByName(ObjName); alert(arrayOfObjects.length); for (var i = 0; I < arrayOfObjects.length;i++) { alert('Inside for loop');............................
I want to call a validate function on asp:button click event and also want to do some server side work on this click like adding values to session variables and redirecting page to new one.
I am binding a checkboxlist with a dataset (with these columns : id,empname,resourceId,balanceId as columns) with datavaluefield as id and datatextfield as empname;
Now, i want to control the selection of the items. Say some thing like
1. "User should be allowed to check only say 5 items with same resourceId" using javascript
2. And in total he should select only 20 items (max 5 items for same resource id and max 15 items for the remaining)
I have a javascript variable in the script tag. I am assigning a value to that variable and I want the same value to be assigned to the label control e.g. consider the sample code below :
I have file upload and Radio button list controls in the page
Requirement:
When the page load, the file upload control has to be enable = false when I click on the radio button list's Yes option then it has to be enable = true and when No option is clicked then enable = false
I would like a total calculation on a GridView column. Here is my code that isn't working. Where am I going wrong? The calculation should be done on GridView2 TextBox13 and the Total should be in TextBox14.
