Javascript - HDI: Disable Postback On Html Input Box

Nov 15, 2010

I have an input box that I don't want postback to occur on someone striking the enter key

<input
type="text"
id="addressInput"
onkeydown="inputenter()"
autopostback="false"/>
function inputenter() {
if (event.keyCode == 13) {
seachLocations();
return false;
}
else {
return false;
}
}

Disable Validation In Order To Keep Some HTML On Postback?

Oct 3, 2012

I have a div where I put a lot of stuff on runtime to construct a chart. The user should be able to copy the chart to another div (innerHTML) and then make som adjustments to the original div, which causes a postback. Of cours the cloned div comes back empty.

So I'm thinking of putting the entire innerHTML in a session variable at page_unload, but then I run into the validation problem. I've tried using a hiddenfield as an in-between control, but it's the same, and it seems you can't use the CausesValidation on that control. I've also tried a regular asp:textbox, but the CausesValidation doesn't have any effect.

How to do this? Or any better way all together on the copy-chart issue?

C# - Javascript Added Input Control On .net Postback?

Jun 23, 2010

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'm trying to write code that will disable submit button (or all submit buttons) on the page to avoid double postback.I thought of generating my own postback javascript function (and inject postback javascript using GetPostbackEventReference) but maybe there are some better ways to do this? Or maybe there is some other way to avoid double postbacks?

How To Disable Usercontrol Postback If Javascript Is Enabled

Oct 20, 2010

I've searched high and low for some resolution to this problem. Hopefully someone here can explain!!I create a usercontrol that uses .NET web controls, but I want to create a smoother user experience by avoiding full postbacks, so I write some JQUERY to capture click events on the client and in this way do the processing without going back to the server.

$("#tblLedgerEntries :checkbox").click(function () {
var value1 = $(this).closest("tr").find("td.invoiceAmount").html();
var value2 = $('#<%=hdnTotalToPay.ClientID%>').html();
CalculateTotalPayable(value1, value2, $(this).attr("checked"));
[code]...

Javascript - Dynamically Disable A TexBox On PostBack?

Mar 25, 2011

I have an application that is supposed to accept checks. The user has 2 radio buttons. The first radio button has a drop down list associated with it which contains the masked numbers of their previously used checking accounts.

The second radio button has three text boxes and an image of a check associated with it.

When a user hits this page, the three text boxes and the check image associated with the second radio button are disabled. Then, if the user decides he/she wants to use a new checking account, they can click the second radio button and that fires the Javascript that enables the three check boxes and the image of the check associated with that second radio button. If they click on the first radio button, it will re-disable the text boxes and hide the check image associated with the second radio button.

The problem happens when I do my server side validation. After validating all text fields, if there is a problem, I just fall out of the bottom of the code, the page posts back and the labels above the offending text fields show an error message.

One caveat: The Javascript that is supposed to fire on the OnClick event for the first radio button fires and the text fields for the second radio button are disabled. The user can click on the second radio button and the fields will enable, but this is very clunky.

Here's the enable code where I am injecting the Javascript:

Private Sub JavascriptInject()
Dim sEnableControls As String
Dim sDisableControls As String

Web Forms :: Postback Using Html/javascript?

Apr 10, 2010

I have a literal control in markup. I am generating html layout in C# and then set the text property of literal to the html.

StringBuilder sb = new StringBuilder()
sb.Append("my html.....");
lt.Tex = sb.ToString();

Some of these html elements need to post back and call a function on the server side. I googled and found a couple of posts using __doPotsBack, but it is not working. Below is how I am adding an image and adding onclick script.

sb.Append(string.Format("<img title="Add" src="images/Add.gif" onclick="javascript:__doPostBack('Add','');return false;"/> "));

It does cause postback, but Add function is not called. Additionally I want to pass some parameters to Add function.

I have a simple javascipt which enables/disables some checkboxes when another checkbox ticked/unticked. This works fine, however, in some instances when by page is loaded my code behind disables the same check boxes. When this happenes my original check box nolonger seems to have any influence in enableing or disabling - there is no error and all the elements seem to be found by the javascript - it just doesn't enable/disable the checkboxes.

I need to change a standard HTML Input button to a Link button but am running into problems because the existing

set the property runat="server" I get a "CS1026: ) expected".

Quite new to ASP,net (VS2010) so could be going about this the wrong way.

Web Forms :: Disable All Click During A Postback?

Jan 13, 2011

I have a master page containing menu items and if i click on any menu item then postback happens(it's not an asynchronous postback) that page loads in the content area. Now, if the page has taken some time to load and the user again clicks some other menu, then at some cases, it is crashing. So what i want to do is when postback is happening, I want to restrict the user to click anywhere on the master page or content page. We have achieved this on asynchronous postback.... But cant find a solution during postback.

Get The Value Of An Input Of Html.textbox In MVC 2

Jul 12, 2010

I currently have a TextBox using: <%: Html.TextBox("TextBox1") %> How do I get the value of what is typed into the TextBox as a string so that I can use that string variable throughout my application? The view has he following with the inherits on top of page to model. This page is named "InputNumbersSection":

<%: Html.TextBoxFor(m => m.Number) %>
and the action:
<%: Html.ActionLink("Get Number!", "DisplayNumbersSection") %>
The Model has this:
public class NumberModels
{
public string Number { get; set; }
}
The controller has the following:
public ActionResult DisplayNumbersSection(NumberModels model)
{
if (ModelState.IsValid)
{
string TextBoxValue = model.Number;
ViewData["Number"] = TextBoxValue;
}
return View();
}

The ViewData I use in another page to return the number from the textbox typed in the view. When I type somthing into the textbox, I do not see the property getting hit or executed. The "Number" property returns NULL all the time. It almost seems as if it is not picking up what I type into the TextBox

Html - Regular Input In .NET?

Jun 7, 2010

Here's an example of a regular standard HTML input for my radiobuttonlist:

<label><input type="radio" name="rbRSelectionGroup" checked value="0" />None</label>
<asp:Repeater ID="rptRsOptions" runat="server">
<ItemTemplate>[code]...

I removed some stuff for this thread, one being I put an r for some name that I do not want to expose here so just an fyi.Now, I would assume that this would or should happen:

Page loads the first time, the None radio button is checked / defaulted
I go and select a different radiobutton in this radiobutton list
I do an F5 refresh in my browser
The None radio button is pre-selected again after it has come back from the refresh

but #4 is not happening. It's retaining the radiobutton that I selected in #2 and I don't know why. I mean in regular HTML it's stateless. So what could be holding this value? I want this to act like a normal input button.I know the question of "why not use an ASP.NET control" will come up. Well there are 2 reasons:

The stupid radiobuttonlist bug that everyone knows about I just want to brush up more on standard input tags.We are not moving to MVC so this is as close as I'll get and it's ok, because the rest of the team is on par with having mixed ASP.NET controls with standard HTML controls in our pages I'm surprised that it's retaining the change in selection after postback.
