View 6 RepliesI have a simple asp:RadioButtonList within a form tag but for some reason it isn't keeping it's value on postback
Here's what I've got
[code]....
When running my application lately, there is a very long delay after a request is made to the server. When debugging and stepping through, the code finishes quickly and then a dialog comes up, which I'm assuming is the reason for the lag. (I've tried a series of other options including disabling usage of ViewState, disabling debugging, installing IE 8 and reinstalling the Ajax Control Toolkit.
The dialog reads as follows:
Find Source: ExtenderControlBase.cs Original Location:
C:UsersswaltherProjectsAspNetAjaxReleases30930AjaxControlToolkitSourceAjaxControlToolkitExtenderBaseExtenderControlBase.cs
I am not familiar with any user on this machine named swalther (it was reformatted rather recently) and searching my computer for this folder turns up no results.
I have two checkboxes: cb1 and cb2. They are both hooked up to an onClick event which checks if at least one checkbox is clicked. If this is not the case, it throws an alert and reverts the change. If a legal change was made (e.g. cb2 was checked, followed by cb1 being unchecked), the function calls the server function checkChange() which needs the object and eventargs.
I'm having trouble with the following:
Reverting the change: how can i find out which checkbox was clicked without adding an extra javascript function for the second checkbox? This has to be a scalable solution as more checkboxes may be added later.
How do I call the server function checkChange(). I am aware of "this.Page.GetPostbackEventReference" but I am confused as to the parameters it takes.
I am developing a web page where a user will submit some "Comments" on a form. When they click the submit button, I fire off some javascript that captures their current GPS location, which I store in a visible Text Box (for testing purposes). If the user is updating from a device that doesn't support gps, I add text to my textbox that says "Device does not support GPS".
When I get to the server, using a device that doesn't support GPS, that text comes through just fine. When I use my iPhone, I see the GPS Coords in my textbox, but that textbox value doesn't make it to the server.I'm thinking that there is a 2-3 second delay from the time that the button is clicked to the time that the java finishes retrieving the GPS. So the textbox text isn't set fast enough.I'm wanting to prevent a postback for 3 seconds (for example) to give the javascript time to update the textbox.
How to delay the Auto postback for 10sec in textbox of asp.net.
I am filling the textbox by using autofill. I'm calling textchanged method in code behind, So I need to delay the Textbox for 10sec. Problem is when I entered single letter it is going for textchanged. so i need to delay the Autopost back
I am working on an Asp.net webiste.The response time(in case of a postback) of the pages in the website is ok on my local machine.But when I uploaded the same website to the internal development server and tried to access the server pages from my local machine,its taking bit long(in case of a postback) as compared to my local machine.I do not understand why the same webiste runs slowly on the dev server..
Following is the configuration of dev server.
Microsoft Windows Server 2003 R2 Enterprise Edition service pack 2
Intel(R) Xeon(R) CPU
E5450 @ 3.00GHZ
3.23 GHZ,2.00 GB of RAM
Physical Address extension
Following is the configuration of my local system
Microsoft Windows XP Professional Version 2002 service pack 2
Intel(R) Pentium(R) Dual CPU

I've got an odd situation with a text box and an autocomplete setup on my page. I'm using a JQuery based autocomplete on a text box that has AutoPostBack="True". This works perfect if I use the keyboard to select an autocomplete item, which then fires Jquery to fill in the text box, and then when I tab out of the box the AutoPostBack fires. If, however, I click on an autocomplete item, my text box loses focus first and the AutoPostBack fires before the Jquery has a chance to change the text in my text box. Is there a way to delay either the PostBack or the Jquery so that they don't fight each other? I'm thinking it may have to be the PostBack that gets changed, since the JQuery would lose it's state on the PostBack
View 1 RepliesI have a radgrid controlling access to an application for users. There are two columns, a 'name' column and a checkbox 'access' column representing their current access permission. the checkboxes are populated from a database. I would like the to change the checkboxes to grant or deny access to the users I specify. Since there are alot of users I would like to make multiple changes and use a submit button to write the changes to the database. I do not want to postback with each checkbox change and wait for the page to "blink". My problem is that with the checkbox postback disabled, when I click submit, the value of the checkboxes are not registering the changes I make. I need a way to access the current client-side state of the checkbox or some workaround to accomplish this.
View 5 RepliesI created checkbox in a gridview. I hope to retain the checkbox value after postback.
[Code]....
I have a project in VB.NET which is working fine which essentially has a Datagrid that has a TemplateColumn included which is a column of Checkboxes. The code to declare the datagrid is here...
<asp:datagrid id="dgDates" OnItemCommand="gridEventHandler" BorderColor="Black" BorderWidth="1px"
CellPadding="3" runat="server" AutoGenerateColumns="False" HorizontalAlign="Left" AllowSorting="True"
OnSortCommand="SortData" OnItemDataBound="gridItemDataBound">
<HeaderStyle Font-Underline="True" Font-Bold="True" HorizontalAlign="Center" ForeColor="Black"
BackColor="#D4D0C8"></HeaderStyle>
<Columns>
<asp:BoundColumn DataField="strParameterName" SortExpression="strParameterName" HeaderText="Parameter Name"></asp:BoundColumn>
<asp:BoundColumn DataField="dtParameterValue" SortExpression="dtParameterValue" HeaderText="Parameter Value"></asp:BoundColumn>
<asp:TemplateColumn HeaderText="Constant" SortExpression="blnStatic" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
<asp:CheckBox ID="cbStaticRolling" Checked="False" Runat="server" AutoPostBack="true"></asp:CheckBox>
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
as you can see the Checkbox has Autopostback="true" but there are other things on the page which produce postbacks as well.
My Page_load has this in it, being called on every load of the page, postbacks included...
Dim strGUID As String
strGUID = Session("strGUID")
dgDates.DataSource = SqlHelper.ExecuteDataset(ConfigurationManager.AppSettings(Web. [Global].CfgKeyConnStringADMIN), "dbo.spRptGetSchedulingDates", strGUID)
dgDates.DataBind()
intNumberOfDates = dgDates.Items().Count
as well my code behind has the following code for the gridItemDataBound
Protected Sub gridItemDataBound(ByVal sender As System.Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs)
'hide the intRptSchedulingDatesID for each row in the checkbox's content style variable
If (e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem) Then
CType(e.Item.FindControl("cbStaticRolling"), CheckBox).Style("Content") = CType(e.Item.DataItem, System.Data.DataRowView).Item("intRptSchedulingDatesID")
End If
End Sub
everything you see sbove is working perfectly fine...in the sense that when I click one of the checkboxes, the page_load fires, the gridItemDataBound fires on DataBind() and when all is done, the checkbox retains the value that the user clicked the checkbox.
With all this exact same code converted to C#....the events all fire in the same order, but the checkbox selected value always clears...any thoughts??
I have a js function
function(id){
// do a postback here and get the id on the server side
}
I need to send the id to the server, how could I do this?
any way will do, using additional/hidden controls anything
I want to highlight every rows in the gridview when the checkbox is selected without posting back to the server. ?
I also want to know how to make a webmail like Gmail, Yahoo.
I want my gridview to redirect to when the row is clicked but excluding the click in checkbox.
I have a gridview with a checkbox in each row for selecting. I want to have a button which will select all/deselect all and not post back.
I first implemented this with a link and it works perfectly, but I don't like how it looks.
Code:
<a href="#" onclick="javascript:sel();">Select/deselect all</a>
Code:
<script type="text/javascript">
isSelected = false;
function sel() {
var frm = document.forms[0];
isSelected = !isSelected;
[Code] ....
So now I have a button that I want to rig up to execute this javascript. Which I believe would be done this way:
Code:
<asp:Button ID="btnSelectAllSummary" runat="server" Text="Select All" OnClientClick="javascript:sel()" />
But it is posting back. How do I prevent the postback and have it execute on the client?
I'm at my wits end on this one looked/Searched/Played/Experimented and I need your help if you can.This page is going to be primarily used on a mobile device using Win Mobile 5 Need to Accomplish:Prevent Postback(serverside) of Page using JavaScript (Postback's slow down the page on mobile device)

I have an issue that seems to only happen on my production server. I show or hide table rows whenever the buttons are clicked. However, when I do a postback on the checkbox, all of the rows become visible and the textbox stays empty. It works correctly on my test server and local workstation, just not in production.
Here is the markup...

Here are the unexpected results whenever I check the chkShow2 checkbox... I am guessing this is a configuration issue on the server.
In design time I created a Gridview and a delete button in a page test.aspx:
[Code]....
The program stopped at statement "if ((row.Cells[COL_INDEX_SELECTED].Controls[0] as CheckBox).Checked)",
because it cannot find the checkbox created before.
I tried to shift all the code in Page_Load to Page_Init, but the ticked checkboxes are still lost.
I could find the ticked checkboxes names in its request object parameters(this.Request.Params.AllKey) if I setup a breakpoint on the error statement.
Does anyone konw what's happening and how to retrieve the selected rows?
I am getting the following error on on clikcing checkbox from checkbox list in my project.
Error:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
If i set <pages enableEventValidation="false"/> then on clicking the submit button the information is not saved in database just page is refreshed.

how can i get the checkbox value to array object using javascript?
I'm using asp.net validation controls which work fine. I've since introduced an HTML checkbox which should be ticked before the form can be submitted. My function for this reads as follows:
function terms(form) {
var terms = document.getElementById("chkTerms").checked;
var errorsArray = new Array();
if (terms == false) {
//alert("Terms not checked (works)");
errorsArray.push("You must agree to the terms and conditions.");
if (errorsArray.length) {
document.getElementById("termsOutput").innerHTML = errorsArray.join("
") + "<br />";
return false;
}
}
else {
document.getElementById("termsOutput").innerHTML = "";
}}
It is called as follows:
<asp:Button ID="btnSubmit" runat="server" Text="Submit" OnClientClick="return terms(form)" />
The problem I have is seems I can either use the asp.net validation OR the custom checkbox validation I wrote. After the form posts however, the asp.net validation fires!

am having trouble with some javascript that isn't working as it should. I have a table with 6 rows in it. There are 3 rows with a checkbox in them and 3 rows with a dropdownlist. The order is cb ,ddl, cb, ddl, cb ,ddl. The ddl rows are all hidden in th beginning using style="display: none;". When the user checks a checkbox, the ddl row below should appear. But this is not happening, instead it happens when i uncheck it.
[Code]....
