Dynamically Invoke JavaScript From Input Box?
Aug 14, 2010
I have a asp.net input box:
<asp:TextBox ID="InCL" runat="server" Text=""></asp:TextBox>
As soon as a number is entered I would like to send that value to a javascript function that updates a Google gauge.
For example, user inputs 77, the google gauge immediately dynamically moves to that position.

I understood that we can use System.Type.InvokeMember() to invoke method dynamically using Reflection, but I couldn't get proper example to show how to work on it. Can anyone please explain how to do it in
Visual Studio 2010
Just for practice purpose I have created one class called MathFunctions like below:
namespaceCSHWEB
{
public
class
MathFunctions
{
public
double
SimpleInterest(double
PrinicipalAmount, double
TimePeriod, double RateOfInterest)
{
return
(PrinicipalAmount * TimePeriod * RateOfInterest) / 100.0;
}
}
}
Now,
how can I invoke above method SimpleInterest with its parameters without instantiating the class?

I have a thread that runs querying a DB and returning some values. If this values satisfyes a condition, I want to raise a message box (javascript alert) for the client side.
In my system, users can post some tasks in DB, and the thread is going to constantly query the database to check if user has things to do. If user has, the system must alert him through a message box.
I've done javascripts invokings with ClientScript.RegisterStartupScript, and Attributes.Add for buttons. But now I want to call the javascript functions (wich will alert the user that he has things to do) from the midle of a sub (that is executed in a thread), without a submit, load or click event. How can I do it?

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.

In code-behind I can do this to select something:
// Select item in first DropDownList
myCascadingDropDown_1.SelectedValue = itemValue_1+":::"+itemText_1;
// Select item in second DropDownList
myCascadingDropDown_2.SelectedValue = itemValue_2+":::"+itemText_2;
How can I do this in JavaScript?
EDIT:
I can select my desired item in the first dropdownlist. The problem is however, that new values based on that selected item (it is a CascadingDropDown, remember?) don't show in the second dropdown so I can't select anything there. I would need to somehow invoke the update method of the second dropdown manually.

I have created button 2 below:
<input id="Button1" type="button" value="Stop"
onclick="alert('hello world');"/>
<input id="Button2" type="button" value="button" OnClik="alert('hello world');"/>
using a litteral tag on page load like this:
protected void Page_Load(object sender, EventArgs e)
{
Literal1.Text = "<input id="Button2" type="button" value="button" OnClik="alert('hello world');"/>";
}
Incredibly when testing in browser, click on button 1 works, not click on button 2 whereas the codes are the same !

Similar to the "add more experience" functionality in [URL], I want to provide a "Add another location" link which should display an additional row of a set of 4 dropdowns (country, state, city, region). I'm actually using the CascadingDropDown jQuery Plugin for ASP.NET MVC [URL] for my location dropdown functionality, but I need to give the user the ability to add multiple locations. What would be the easiest way to handle this in ASP.NET MVC and jQuery?

I'd like to add a description field to an application that can be as long as several lines (or even paragraphs) or as short as a one-liner.Instead of taking up a lot of screen real estate or have scroll bars, it would be preferable to have the textbox grow based on its input.
On IE6 adding Style="overflow-y:visible" accomplishes this nicely (both on display of read only, and if we are in edit mode).
However, it has no effect on Firefox, or IE7 for that matter.

Here is my div that is contained more than once by my page:
<div class="formContainerDiv" style="width:165px">
<table>
<tr>
<td colspan="2">
Assign To<br />
<asp:CheckBoxList ID="CheckBoxListLoginUsers" runat="server">
</asp:CheckBoxList>
<br />
Note<br />
<asp:TextBox ID="TextBoxNote" runat="server" TextMode="MultiLine" Width="150" ClientIDMode="Static" class="textBoxNote"></asp:TextBox>
<br />
</td>
</tr>
<tr>
<td>
<input type="button" class="saveAssignment" value="Save"/>
</td>
<td style="text-align: center;">
<a href="javascript:void(0)" class="formContainerDivClose">Close</a>
</td>
</tr>
</table>
</div>
And that's my jquery function:
$(".saveAssignment").click(function () {
var div = $(this).parents(".formContainerDiv");
......
});
I can select the appropriate formContainerDiv. But I need to get the values of checked checkboxes and the value of TextBoxNote.

What I'm trying to achieve/plan, is whereby a page loads with a set of inputs, e.g. TextBox, Radio List etc. Taking TextBox as an example, there is a button for the user to "Add" another textbox to the page (in the same group), e.g. Member1, Member2, Member3 etc etc.
Two questions:
I could add these with Javascript, however the resultant "save" on postback would not get these inputs? If so, how? The form needs to work without Javascript as well, so postback to dad another control is fine, however if I click the "add" button again, it will only ever add one control.
protected void btnAdd_OnClick(object sender, EventArgs e)
{
holder.Controls.Add(new TextBox { ID = "txtControl1" });
}

I have been trying to set the value of a hidden input by using Javascript and then access the value from within my C# codebehind. When I run the code that is copied below, the value that is assigned to assignedIDs is "", which I assume is the default value for a hidden input. If I manually set the value in the html tag, then assignedIDs is set to that value.
This behavior suggests to me that the value of the input is being reset (re-rendered?) between the onClientClick and onClick events firing.

I'm trying to devise a form that will allow me to input multiple contacts. It's a pretty long form so far and I want to keep it as short as possible. I was thinking of just having one set of fields for contact inputting which will add this contact to a list box or gridview but I'm not sure that is the most elegant solution. Could anyone else point me in the right direction to something good I can use?
I'm writing in HTML / asp.net / javascript.
