A breakpoint is set on FillForm() and this method is called two times but I can't explain myself why this happens. I have client side javascript code, when the form is being send, the onsubmit method is also called twice... Where do I have to search?! Is it a (known) bug? Think I could get it to work with this Thread: [URL] But why is the event fired within the onblur-event when it's fired anyway??
I have one Button (Refresh Button), One ComboBox (containing DEV and UAT as its items) and a GridView on my asp page.
I am filling up my Grid with values from database on the ComboBox's 'TextChanged' event and Buttons's 'Click' event.
First time when page is loaded, there is no information in the grid, but when i choose DEV/UAT from the ComboBox 'TextChanged' event is fired, the grid is filled with the relevant data. That is what i want.
When i click the Refresh Button to refresh the data again, first comboBox's 'TextChanged' event and then 'btn_Click' event is fired.
I want then when a button id pressed only 'Click' event to be fired and not the ComboBox's 'TextChanged' event.
i have written an button click event in js file but the event wasnt fired the code seems below
$("#btnSearch").click(function () {
debugger; alert("search button event fired");
$("#ctl00_MaintenanceContentHolder_btnSearch").click(function
ugger; alert("searchbutton event fired");
There is a bug in jQuery 1.4.2 that makes change event on select-element getting fired twice when using both DOM-event and a jQuery event, and this only on IE7/8.Here is the test code:
<html>
<head>
<script src="http://code.jquery.com/jquery-1.4.2.js" type="text/javascript"></script>[code].....
This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem.

View 20 RepliesI have created some dynamic controls, at the runtime from server-side and I want to write the event-handler for those controls. All I did is :
// Defined the control as
[Code]....
// And I wrote the even handler as :
Private Sub addobjective(ByVal sender As Object, ByVal e As System.EventArgs)
End Sub
My problem is the event-handler function addobjective() is never being called and not getting fired, So the program is not doing what it is supposed to do at the click event of the server side commandbutton add.
I have two search textboxes and two corresponding buttons on my web page.One of the textboxes is a default textbox coming from the .master page and the other one is local to the page.Now,when I enter some text into the local textbox and press enter, the event of the master page button gets fired instead of that of the local button.How do I fix this issue? I tried to shift focus to the local button and on the text changed event but the master page button event is always the last one which is getting fired. I tried changing both the buttons to LinkButtons but then enter doesn't work!A

My page contains a button [Button1].I've dynamically created a new button [Button2] in the Button1_Click event and and assigned event handler also.But when clicking on Button2, Button2_Click event is not fired.I think its because the page looses dynamically created Button2 after post back, since it is created in Button1_Click event.Is there any way to maintain Button2 on page and raise Button2_Click event ?

View 6 RepliesI have a very simple asp.net page, just some buttons and one GridView on it. The logic is a user click the QUery button,then the button click event was trigured to populate the gridview with data queried from database via LINQ. for a user friendly interface, in RowDataBound event, I visit every row, change a boolean value into checkbox represention. But it seem that the RowDataBound run twice, because the checkboxs were inserted twice for every row in one cell. so why? the source code snippet as follow:
protected void btnSelect_Click(object sender, EventArgs e)
{
RetiredEmployeeDataContext db = new RetiredEmployeeDataContext();
GridView1.DataSource = db.ENTUserAccountSelectAll();//userAccounts;
GridView1.DataBind();
}
protected void GridView1_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox chkActive = new CheckBox();
chkActive.Checked = ((ENTUserAccount)e.Row.DataItem).IsActive;
chkActive.Enabled = false;
e.Row.Cells[5].Controls.Add(chkActive);
}
}
I have a user control that displays some database records when I first hit the page. When I click the submit button the page load event fires again, loading the user control again. Then the button click event fires inserting a new row in the database which is not shown on the page because the user control already did its stuff. If I could get the user control to do its stuff after the button click event I could then see the newly inserted row. I can do this by pulling the code out of the button click event and sticking it in the page load event. However, I think that would be bad code flow. How can I get the user control to do its stuff after the button click event has fired?
