Web Forms :: Fire Dropdownlist Selectindexchanged Event
Jul 22, 2010I added dropdownlist & textbox control to gridviewrow dynamically on button click.I bind datatable to dropdownlist programatically & dropdownlist Datatextfield="product" & Datavaluefield="Amount". now my question is: when I select a product in dropdownlist,the corresponding product item "Amount" should display in the textbox. I write in my dropdown event like this:
protected void ddl1_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow gridViewRow = (GridViewRow)(((Control)sender).NamingContainer);
DropDownList ddl1 = (DropDownList)gridViewRow.FindControl("ddl1");
TextBox itProductQuantity = (TextBox)gridViewRow.FindControl("itProductQuantity");
itProductQuantity.Text = ((DropDownList)sender).SelectedValue;
}
I call that textbox in Gridview row databound. why event is not firing?
AJAX :: How To Fire A ModalPopupExtender On The SelectIndexChanged Event Of A Dropdownlist
Mar 17, 2010How can I fire a ModalPopupExtender on the SelectIndexChanged event of a dropdownlist?
I only want it to fire when a particular value is chosen in the list.
I tried leaving the PopupControlID value out and calling .Show() on my extender in the onselectchanged event, but it would not allow me to have a blank PopupControlID. If I set the PopupControlID to the ID of my dropdownlist, the popup fires as soon as I click on the dropdownlist control.

Web Forms :: Button Click Event Not Getting Called Due To Tag?
Feb 23, 2010In my web form, i am having button named "btnSave" and there are some textbox controls (to name few, Emp Number, Full Name, etc). I've added RegexValidator to the textbox controls as below:
<asp:RegularExpressionValidator
ID="employeeNumberValidator"
ValidationExpression="^[0-9]+$"
ControlToValidate="txtEmpNumber"
ErrorMessage="Only integers are allowed"
runat="server">
</asp:RegularExpressionValidator>
This RegexValidator will check for emp number textbox contains only integers and if not, it will display message "Only integers are allowed". Now, in my btnSave_Click(...) event, i am first validating whether the textbox contains data and if not, then i am highlighting the textbox in red. When txtEmpNumber contains non-integers data and if i click the Save button, the code in inside btnSave_Click(...) event is not getting called. But when i provide employee number in expected format and then click Save button, then the code inside button click event is getting called without any issues.
I am not sure why my btnSave_Click(...) is not functioning when Employee Number has data in incorrect format.

Web Forms :: CompareValidator Is Called Before Onblur Event?
Jan 11, 2010I have a text for user inputs Date. There is a CompareValidator which is used to compare Date between 2 TextBoxes. User do not need to input separator. After finish inputting value, he presses Tab to call a Javascript function to Format value of this Textbox.
Ex : user inputs
TextBox1 (From) : 01012010 =>Press TAB =>Value : 01/01/2010.
TextBox2 (To) : 01022010 =>Press TAB =>Value : 01/02/2010.
But Compare Validator show Error after cursor leaves the TextBox2. If I choose these values from Date Picker => No problem.
I think Compare Validator is called before onblur event. Is that right?
If it is right, is there any way to do my work?
Web Forms :: TreeView TreeNodePopulate Event Called Before Page_Load?
May 20, 2010I have a TreeView on a page which I will populate the nodes on demand and a checkbox, and they are in the same updatepanel. I can dynamically add new nodes to this treeview. But when I click the checkbox which will cause a postback, the TreeNodePopulate is called before the Page_load and it will regenerate the nodes that was added before. I was very confused how could this be happened. Is this related with PopulateOnDemand and Expanded priorities?
View 3 RepliesWeb Forms :: Button Click Event Is Called Before Page Load?
Oct 8, 2010I just discover why some validation is working bad on some of my forms: the button click event is being called before page load.
What I need for good is (I consider this is a normal cycle of events):
The user press a buttonSome validation occurs at client side (js function returns true if success)Some validation occurs at server sideThe page loads again showing the results
But this is what I get (BAD):
The user press a buttonSome validation occurs at client side (js function returns true if success)The page loads showing no results, because server validation hasnt happened yet Some validation occurs at server sideThe page doesn´t loads again and I cant see the results, so my client cant know what happened on the server side
This is how I tried to implement this:

Web Forms :: Button Event Be Called From Another Button Event?
Sep 17, 2010I have a search page. Based on the user that is logged in, a link will display if they have saved any previous search criteria. If you have any, the link will open a modalpopup with a list of all your saved searches. I have it setup so when you select the search you want to perform, it will take those values and populate the search form for you. What i would like to do is if you select something from the list, after the fields are populated(which is already working) i would like that searches button event to be executed so the search values are passed in and the results are shown instead of having them press the search button again.
I tried adding this to my select event but thats not correct i know.. so is it possible to execute another buttons event?

C# - Accessing The Form Collection In An IHttpModule Causes Event Handler Not To Get Called On Default Page
Mar 18, 2011I've created a simple sample site to demonstrate the issue. In it, I have a Default.aspx Page that has a button on it:
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<p><asp:Button OnClick="ButtonClick" Text="Button" runat="server" />
</p>
<asp:Label ID="output" runat="server" />
</asp:Content>
The code behind just sets the label text on the button click:
protected void ButtonClick(object sender, EventArgs e)
{
output.Text = "Button Click!!";
}
I then have an IHttpModule that gets called for every request:
[code].....
And now it's broken again! So to make a long story short, just by accessing the Form collection on the request in the IHttpModule, I somehow screw up the PostBack, and the event never gets fired.
AJAX :: Fire A Javascript Onclick Function Before The Server Side Event(SelectedNodeChanged) Called?
May 12, 2010I have developed a web application which contains aspdotnet treeview control. In this treeview control has binded with some database value.. that controls has one parent node and more than one child nodes for each parent node.
my problem is here, when the user clicks the parent node, I need to fire a javascript onclick function before the server side event(SelectedNodeChanged) called..
If I provide javascript to the parnet node when it is binding, then I could not fire the server side event(SelectedNodeChanged).
How to provide onclick javascript event for parent node in treeview control even the parent node has SelectedNodeChanged event.
C# - Page Life-cycle - What Tool ( Perhaps Reflector?) Would Enable Me To View The Order In Which Page Events And Their Event Handlers Are Called?
Mar 3, 20101) I know there are lots of web sites that describe in what order events are called during the Asp.Net page life-cycle. But is there also a tool, perhaps Reflector, that would enable me to figure out by myself in what order are ALL the page's events and their event handlers called during the page's life cycle? 2) Would you say that trying to figure out exactly what is going on under the hood is a good idea or a waste of time? To clarify - I'd like to figure out exactly what is going on when a control tree is build - thus all the method calls, all the events called etc needed for control tree to be build ( I imagine there are hundreds or perhaps thousands lines of code written just for building a control tree).
View 4 RepliesWeb Forms :: Dropdownlist Control SelectedIndexChanged Event?
Jun 22, 2010I have one dropdownlist control which populates values to other controls. Means upon selecting item in dropdownlist, related data is populated in other controls. I have also assigned dropdownlist's autopostback to TRUE. Everything is working good as far as dropdown has more than one item.
Whenever there is only one item, selectedindexchanged event is not fired (obviously.....) and eventually the data is not populated to other controls.
How could I get rid of this scenario? I mean which event should I use to avoid this?
At this time, I have just added the first item as something like "---Select Item---" , so when end-user has to select different item and thus the selecteditemindexchanged is fired. no biggie... but just wondering if proper solution is available....
