Im using a image button in my usercontrol to avoid postbacks on its click event.but im unable to stop it .
This usercontrol will be loaded into an ASP page on its load.
<input type="image" src="../Images/plus.gif" onclick="addElement(TopFrame1_PnlAxnCds1,TopFrame1$ddlMitigtAxnCd11);" name="AddMore"/>
Currently users select a record in a gridview and click on the delete button. Delete button passes certain variables to identify the record, makes a SQL connection and then deletes the record by executing a stored procedure. This is way the delete button's code behind works. Now we need a confirmation box if a certain flag is False. If the users select YES then they should be able to delete any way otherwise clicking on Cancel should stop the operation. I don't want to use the onClientClick event of the button like many examples on Web show, instead I am using the jQuery, that uses the button ID and pops up a confirmation dialog. The issue I am having is even if the Cancel button on the confirmation dialog is clicked it still goes on to run the code behind, executes the stored procedure and deletes the record. The browser being used is IE 7.0, how do I stop the button from running the code behind in the button_click event if they select cancel?
I have tried return false, e.preventDefault();event.propagation, event.returnValue = false etc but can't stop it. Here is the jQuery, that goes to the webservice when clicked and determines whether to display the confirmation or not when another stored procedure returns the record count of 0 or more. Like I said it works fine in getting the flag value from the SQL but does not stop at the client level and continues on to the code behind of btnDelete.
$(function() {
$("#btnDelete]").click(function(e) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "WebServices/myServices.asmx/ConfirmDelete",
data: "{}",
dataType: "json",
error: function(req, msg, err) { alert(req, msg, err); },
success: function(msg) {
if (msg.d == 0 && !confirm("Do you wish to delete this record?")) {
event.preventDefault();
return false;
event.returnValue = false;
}
}
});
});
});

View 2 RepliesI developed a Webpage in ASP.NET - the page has a button that starts a DOS-Program on click.Here is the Code:
if (!String.IsNullOrEmpty(endTime))
{
Process p = new Process();[code]....
The code works fine and starts the Process.Now the Problem: I click on the button and the process starts (I see this in the database) and the program works fine, however, I want to stop the process now, but don't know how.
There isn't a DOS-Window where I can click "CTRL + C" or something.What can I do to stop the process?And which User is used for starting the Process?
I am performing "semi"-custom paging for my dynamic LINQ query. However, if the number of results returned exactly fill the page, then I wind up with one extra page that's empty and I can't figure out why. i.e. if I have a page size of 15 and 14, 21, 101, etc. items then everything is fine. However, if I have 15, 30, 45, 60, etc. then I get one extra blank page and I've been unable to make it stop. Anyone have some ideas except to add a new record when I see we're sitting on a multiple of the page size?
I write out the paging control like this and it loops through one time too many if the last page is full...

Just wondering if anyone has ever managed to find a way to have a datagridview image button column in a template field which display different images on different rows depending on some data element in the row. Our application needs to display a series of fees charged against an account column which will be either less then 500, 500 to 1000 or >1000. Some of those fees are charged at a full rate, others at a partial rate, and some are not charged at all. The user would like to see a simple 3-state graphic which would convey the simple info: full-charge, partial-charge, or no-charge. Sounds easy enough but I've not yet managed to find a way to do this. Every time I attempt to modify the individual cell's graphic it seems to want to change the graphic for all the rows.

I have four Imagebuttons that I want to disable depending on the Role the user belongs too. I know how do do this in a gridview or detailsview but for some reason it isn't working on just a plain form. So when a User who is not in the "Admin" role logs onto the page he either doesn't see the button or the hyperlink has been disabled thus not allowing him to proceed any further.
