Here's what is in my .aspx:
<div> <input id="testButton" type="image" src="<%=TestImageUrl %>" onserverclick="RedirectTest" /> </div>
And in my code-behind this:
protected void RedirectTest(object sender, EventArgs e) {
// Logic is here}
It's not hitting my method at all when I click the image. And please note, I do not want to use an ImageButton. I want to figure out how to get this working with a plain old input tag.
The event is simply not firing, what am I missing?
Code for the button:
<input type="button" class="button hide" id="savetext" style="float:right;" value="Hello" runat="server" OnServerClick="savetext_Click"/>
And the code that is generated (i.e. when opened in a browser and the source is viewed) is this:
<input onclick="__doPostBack('ctl00$Main$savetext','')" name="ctl00$Main$savetext" type="button" id="savetext" style="float:right;" class="button hide" value="Save to text" />
I've got <pages clientIDMode="Static" /> in web.config but the name and generated onclick event are prefixed despite that. Server side code:
Protected Sub savetext_Click(ByVal sender As Object, ByVal e As System.EventArgs)
End Sub
To be clear, my goal is to register a click on a button server-side, not just client-side.
protected void btnNext_Click(object sender, EventArgs e) { btnNext.InnerHtml = "CLICK";
} <button type="submit" runat="server" onserverclick="btnNext_Click" id="btnNext">Next > </button>
This works fine, but when I add an onclick event:
<button type="submit" runat="server" onserverclick="btnNext_Click" onclick="return checkForm();" id="btnNext">Next > </button>
And in the head:
<script type="text/javascript"> function checkForm() {
if (document.getElementById("<%=lstChooseSpec.ClientID %>").value) {
return true; } else {
$.jGrowl("<strong>Warning!</strong><br />Please select an item", { sticky: true });
return false; } } </script>
It submits the form, but doesn't change the buttons text to 'CLICK'. The text only changes to 'CLICK' when the onclick() isn't defined, although the form is still submitting!
I have a form with my own JQuery validation. When a JQuery <button id=btnRegister type=submit> is clicked, my validation code is invoked and if invalid, form does not submit. All works great. I have another <button id=btnSave> on this form. I would like btnSave to fire asp.net server side event (onserverclick) only if form data is valid. I have tried following -
<button type=submit onclick='if($(this).closest('form').submit()==false) return;' onserverclick='btnSave_click' runat =server>Save</button>
When I click on the btnSave, it does invoke my form's submit event handler, which correctly returns false, if invalid. So far so good. After this point, I would like the onserverclick event not trigger. However, the onserverclick does trigger and the page posts back, even when the form is invalid. As I see it, cannot have onclick and onserverclick at the same time. What should I do to make them co-exist harmoniously? If I change <button> to <input type=submit> it all works out. But I like <button>'s look and feel more.
I have several html buttons on my form which I have calling the same routine in my code behind.
For example:
<input id="cmdSaveChangesOnEdit" type="submit" value="Save Changes" name="cmdSaveChangesOnEdit" runat="server"
OnServerClick="cmdSaveMainPricingChanges" />
<input id="cmdSaveChangesOnEdit_NEW" type="submit" value="Save Changes" name="cmdSaveChangesOnEdit" runat="server"
OnServerClick="cmdSaveMainPricingChanges" />
I would like to replicate this functionality with the asp:DropDownList control i.e. I have several dropdowns which I would like to call the same code behind routine. However it seems that asp controls do not support the OnServerClick option. Is there a way to explicitly define which code behind routine to call on an asp control?
I have been experiencing some very strange behavior using html buttons with the onserverclick attribute. What I am trying to do is use jQuery to designate the default button on the page. By default button I mean the button that is "clicked" when a user hits enter. In testing, I would hit enter while in an input field and sometimes the intended "default" button was clicked and the server side method defined in the corresponding onserverclick attribute was hit. Other times a post back was made without hitting the server method. In order to isolate the issue I created a minimal test case and found some very interesting results.
Client side:
[Code] ....
Server side:
public partial class admin_spikes_ButtonSubmitTest : System.Web.UI.Page {
protected void Page_Load(object sender, EventArgs e) {
} protected void ServerMethod1(object sender, EventArgs e) {
_response.Text = "server method1 was hit";
} protected void ServerMethod2(object sender, EventArgs e) {
_response.Text = "server method2 was hit"; } }
What I found was that everything worked as expected with this code except when I removed one of the input elements. In Firefox 3.6 and IE 8 when only one input exists on the page, hitting enter does not trigger the onserverclick, it makes a post back without even being jQuery "clicked" or actually "clicked". You can test this by starting with two inputs and clicking "test2". This will output "server method2 was hit". Then just hit enter and the output will be "server method1 was hit. Now take away an input and run the same test. Click "test2" see the results, then hit enter and you will see that nothing will change because the "test1" method was never hit. Chrome worked as expected
I would like to do the validation work using javascript or jquery in onclientclick and then show blockUI, next page using server click. But, I have a captcha validation in server click and I don't know how to validate the captcha in jquery or javascript.
protected void btnRegister_Click(object sender, EventArgs e) {
lblMessage.Text = ""; if (Page.IsValid) { if (txtUserName.Text == "") {
lblMessage.Text = "نام کاربری را وارد نمائید";
txtUserName.Focus(); return;
} if (!BLL.IsStrictPassword(txtPassword.Text)) {
lblMessage.Text = "طول کلمه عبور حداقل باید 5 کاراکتر باشد";
txtPassword.Focus(); return; } if (ddlYear.Text == "<سال>"
|| ddlMonth.Text == "<ماه>" || ddlDay.Text == "<روز>") {
lblMessage.Text = "لطفا تاریخ تولدتان را وارد نمائید";
return; } if (!chk_Low.Checked) {
lblMessage.Text = "برای عضویت می بایست قوانین سایت را بپذیرید"; return; } if (txtSecurityCode.Text == String.Empty) {
.Text = "کد امنیتی را وارد نکرده اید";
txtSecurityCode.Focus(); return; } secCode.ValidateCaptcha(txtSecurityCode.Text);
if (!secCode.UserValidated) {
lblMessage.Text = "کد امنیتی نادرست وارد شده است";
return; } try { //some code } }
When I write the code for Each HtmlAnchor a in Me.Master.FindControls("link" + i)
AddHandler e.OnServerClick, AddressOf OnClick
end for
I get an error that OnServerClick event is protected and I cannot access it. The question is how do I dynamically add event handlers to HtmlAnchor controls?
I've created some dynamic buttons on page load but the buttons need to have an onserverclick event and pass a value. I used buttons because they can pass a value. My code below so far, just outputs onserverlick to the html page, which is obviously not what I want. Would it be possible to use some other method, I originally used hyperlinks until I needed to pass a value (I didn't want to use querystrings).
[Code]....
I'm new with ASP.NET, and this is my first project that make myself cruel. I'm trying to create a link on every row that created dynamically.(I'm using GridView). The Problem is, the onserverclick eventhandler show nothing.? Heres the code:
public void GridV_RowDataBound(object sender, GridViewRowEventArgs e) {
if (e.Row.RowType == DataControlRowType.DataRow) {
e.Row.Cells[0].Text += "<font id='12345' runat='server' color='blue'
BACKGROUND-COLOR='#9471DE' style='cursor: pointer' Title='Click this:
to view to the Root menu of the thread'><U> <a onserverclick='Submit_Click'>This is description</a></u></font>";
e.Row.Cells[0].Text += "<br/>";
e.Row.Cells[0].Text += "<div id='DataDiv' style='overflow: auto; border: 1px solid olive;
width: 888px;'>"; //height: 300ox; onscroll='Onscrollfnction();'>";
FindHttpVideo1(dDataset.Tables[0].Rows[e.Row.RowIndex].ItemArray[0].ToString(), e, 0);
e.Row.Cells[0].Text += "</div>"; } }
Here the click EventHandler on also on code behind :
protected void Submit_Click(object sender, EventArgs e) {
Label1.Text = "Hello --->"; }
I don't want use Java script to for onclick() handler, I want to do it on code behind.

I am a new to WCF. I have written ajax to use a web service before, but on this project I am trying to use ajax to WCF.After I build the project and wcf using ajax, I receive the return successfully. But, 10 or more minutes later I don't get a return, the ajax calls the error function, and the fiddler returns nothing.
If I rebuild the project without any source modifying, I receive the return successfully again.
In regards to web development PHP works seamlessly embedded inside HTML pages and is parsed before the HTML itself (hence the name PHP!).I'm thinking of starting to learn ASP.NET and C# and it greatly boggles me how do these two Microsoft technologies work in tandem when compared to PHP which is a single entity in itself. I still can't understand how any logic written in C# files is tied to HTML pages that contain ASP.NET scripts.

I am about to give up on this pos...unless somebody here simply gives me the right code to fix my problem. I'm tired of running in circles, and scouring the internet with no progress at all.
Problem: not updating collections with FK's.
Example:
Forum forum = new Forum("Sample");
category.AddForum(forum);
categoryRepository.Update(category); <- fails with transient object error for forum with no CategoryId.
Mapped right using References<Category> and HasMany<Forum>. Conventions are as follows.
Ref:
instance.Column(instance.Property.Name + "Id");
HasMany:
instance.Key.Column(instance.EntityType.Name + "Id");
instance.Cascade.All();
instance.Access.ReadOnlyPropertyThroughCamelCaseField(CamelCasePrefix.None);
Now, I've tried every possible setting for inverse, all the different cascades, on both sides. Nothing works. It just flat fails, telling me it can't insert NULL for Forum.CategoryId (field, not entity prop).

I have an aspx page with a Menu web control. The menu web control renders as a html table on browser. My plan is to add css styles on the aspx page which will be sent to the browser. Let's say I add the following style to the aspx page
td
{
background-color: Red;
}
This style gets sent to the browser together with the rendered html table
<table>
<tr> [code]....
But the style is not applied. I'm really puzzled why this is the case. In general how do we predict the effect of CSS on ASP.NET wen controls?

Now I have run into new problems I'm building a blog in .NET MVC and I have made a SP for inserting member details. Now I have split the member table in ZipCode and City then I have FK in member to these fields. My problem is that th FK in member table is INT and I want to pass in VARCHAR to the db so I can check if the zipcode and city exists, if they dont exists I insert them and get the id to insert into member table. My problem is that I can't mapp it this way in Entity Framework, so I wonder if there is a way to work around this in the sp? ZipCod I think is Postal Code in English.

Any reason an ASP.net 2.0 App would not work on a MAC?
View 1 RepliesI have a problem where our CSS file is not playing nice with the CSS in a wrapper we're injecting our content into. I have some rules specified in our CSS file with !important declarations because the wrapper's CSS is causing the browser to ignore my rules. Unfortunately, this is overriding the styles in the wrapper and I don't want it to do that. You can see an example of this here:
[URL] (our content is 'FUND SEARCH' & below)
The !important declaration in some of my CSS rules is causing the links in the navigation bar on the left to change size when you hover the mouse over them. If I remove the !important declarations however, the links in the table & the clipboard start to misbehave, in that they start changing size when you hoverover. (to see the clipboard in action, check a few of the boxes in the table & click "Check Your Selection")
I know our CSS isn't the best, how I could go about getting both to work together?
I also tried prefixing all my rules with ".content " because all of our content exists inside a div with the class "content" but that had no effect.
