I am not sure why the check change is not getting trigerred. And, is this code correct for selecting only one checkbox
My forst post here + I am new to Asp.Net as well. 2nd my apologies if this question has been asked before.
Here is my problem. I am given some really abstract ASP.net pages, where I have to make a change. My change involves adding some links and on each link I have a function which is triggered when link is clicked on. This function validates some information in the form and then submits this form. This same form contains mulitple list boxes, all of them has AutoPostBack=true. The problem is when I select an item from listbox the form is submitted as I can print all the form properies on the page(all fields with their names and values) however, when I click on link and call the same forms submit(); method I dont see that happening. none of the form fields are printed out.
Now once I click on listbox and select an item after that as long as that item is selected, I can click on all links and they all call the submit() method of the form and it produces required resutls. I am really baffled as this doesnt seem correct as far as simple html is concerend.
I m trying to stop the postback causing by ddl. I have tried the following code but still pb doesnt stop:
<script type="text/javascript" language="javascript">
var ddlSubCategory = document.getElementById("ctl00_m_g_73a5a887_bd36_4a37_966a_ed640c804a84_ctl00_ctl04_ctl09_ctl00_ctl00_ctl04_ctl00_ctl00_SubCategory"); //Get this form html source
ddlSubCategory.removeAttribute("onchange"); //Here "onchange" attribute causes post back
</script>
I have 2 pages (let's say one is a.aspx and the other one is b.aspx). In the b.aspx, there is a nested listview control (let's say outer listview and inner listview).Therefore, there is an event on databound for the outer listview. so basically, the event will programmatically bind the datasource for the inner listview.
Now, in a.aspx there is a button to open a new window (with unique window name) b.aspx. The very first time click on the button, a.aspx opens a new window for b.aspx without triggering the databound event. However, the second click and so on will trigger the databound event which is causing an error because there is no data yet in the outer listview.My question is, what could have possibly triggered the databound event while there is no data in the listview?
I tried to call a java script in onchange event of the check box.
It works in IE8 but not in IE7.
Is there a way to make it possible in IE7.
I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.
View 3 RepliesI have a checkbox inside a repeater like below..I'm having trouble figuring out how I need to tie the onclick event to a javascript function..I know I need to use somthing like
butSubmit.Attributes.Add("onClick", "return confirmSubmit();") but Since my checkbox is inside a repeater and I'm using master pages. I'm not sure how I need to use the findcontrol to so I can call the Add method?

I have to create a HtmlInputText control in code and while in code set it so that it will respond to text changes purely on the client side and not generate a server side event. In an aspx page this would be done like so:
<input id="txtBox" runat="server" onchange="clientsidefunction();">
But in creating this control I cannot determine anyway of setting the onchange client side event. I can setup a server side event by entering:
AddHandler txtBox.ServerChange, AddressOf.serversidefunction Is there anyway to set the clientside onchange event?
I am having a DOB text box. This text box also allows to enter the date and also to pick the date using ajax CalendarExtender.
I used to set the dirty message when we edit some thing in the page.
When I enter some thing on the text box and click on the cancel button, dirty message will occur.
The problem i am facing is that, in Edit mode, I used to get all the records and assign to the text box. In that scenerio, the dirty message si automatically set since the DOB gets changes.
Please find the below code.
<asp:TextBox onkeyup="SetIsDirty();" TabIndex="4" onclick="ClearErrorMessage();"Â
ID="txtEndDate" runat="server" CssClass="input-value"></asp:TextBox>
<ajax:MaskedEditExtender ID="MaskedEditExtender1" runat="server" Â TargetControlID="txtEndDate" Â Mask="99/99/9999" MaskType="Date"> Â
</ajax:MaskedEditExtender>

I have a scenario where i have 4 asp buttons , on click of each button there are 4 labels inside 4 seperate divs where each displays seperate data.
Now if i click second button i need to display second label text inside 2nd div and hide all other divs.How can i achieve this ?
 OnClientClick event of each button calls displayAlternate() which displays repective div and hides other.
displayAlternate('second'); return false; --> if i do this server side event is not fired ...
If I return true div second label is not getting displayed..
How can I achieve functionality where all divs expect 2nd is hidden and i get server side event also..

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>

View 4 Repliesi have a check box list control that is used for showing related files to some post.
what i want to do is set the databound items "checked" to true by default
then,
if a user unchecks some item and clicks the save button. then the selectedindexchanged will fire and i will do some logic.
what i have done is.
--Set All Databound items to "checked" --
[code]....
in the end i want the item that was unchecked to be removed (all other items will remain checked). but even before that, when the user control is loaded all the files that were bounded are being deleted by the index change event.

It works on Internet Explorer but I have few users who started to use apple's snow leopard and event is not at all firing on those browsers.
I believe some browsers have different JavaScript implementation
I have a problem with the ASP FileUpload control. It occurs in Safari and on websites where anonymous authentication is disabled and windows authentication is enabled.
When I select a file in the upload-control and then press an ASP-button the serverside event for the button is not triggered and PostBack is false.
Steps to reproduce the error:
1. Create a page with a file upload and a button. Print a message in the page's load event so you can see that if postback is true or false
2. Open IIS-manager and Add a new application that points to the folder where the page is
3. Disable Anonymous Authentication, ASP.NET Impersonation and Forms Authentication for the application
7. Enable Windows Authentication for the application
8. Browse to the page with Safari
9. Select a file with the upload control
10. Press Ok. Postback is false
If you then enable anonymous authentication on the web application and restart the browser postback works as expected.
How do i load the dropdown list with a selected value there is a also an onchange event?
List<SelectListItem> environments = new List<SelectListItem>();

I have developed and multicolumn combo box server control using textbox and image(for arrow) as described in following sample
http://www.codeproject.com/KB/custom-controls/Multi_Column_Combo_Box.aspx
It is working fine. Now what i want is to implement is client side "onchange" event.
for e.g. if we want to call javascript function on selection change event of dropdownlist control then we can do it as follows
DropDownList1.Attributes("onchange") = "javascript:Validate();"
Here "onchange" is inbuilt client side event for dropdownlist control
Similarly i want such client side event that the is fired when selection is changed in my multicolum control,something like this
MultiColDropDown1.Attributes("onchange") = "javascript:Validate();"
I have a page on which everything is loaded dynamically.
There is a Gridview (AutoGenerateColumns=true) and in the RowDataBound I check every column for a boolean datatype. If found I add a checkbox (autopostback=true) to the cell and register the CheckedChanged event.
The problem is, that I only get the CheckedChanged event, if I reload the grid in Page_Load:
protected void Page_Load(object sender, EventArgs e) {
LoadGrid();
}
But this is very expensive and causes that the db request will be executed twice. If I changed the code to what I want:
protected void Page_Load(object sender, EventArgs e) {
if (!this.IsPostBack)
loadGrid();
}
I get no CheckedChanged event.
Is there a possibility to get:
- Adding a Checkbox in RowDataBound
- Only "LoadGrid()" if it is no PostBack
- Getting the CheckedChanged event of the relevant row
