call JavaScript - jQuery code from ASP.NET Server-Side

  
jQuery got so close to me lately that I can see myself adding the scripts to my project almost unconsciously. The thing is, jQuery is very useful for me, in almost all situations and it has been a do or die enhancement for all my project since I first put my hands on it.

Of course while using it, you encounter few situations which need a bit of research to solve, mostly when you are trying to combine it with some other technologies like: UpdatePanels and ASP.NET Ajax. For instance there are many situations when I would like to run some jQuery magic based on some decision that I make on the server side.

Server Side Code Not Firing After Javascript Function

  

I have a group of buttons and a text box which I have been using for paging. The user is able to type a number into the text box and either click the "Go" button or hit "Enter" for the paging to occur. To have the "Enter" button work I had to turn the "UseSubmitBehavior" property to false for all of the buttons except the "Go" button.

Now I am trying to add a javascript function that shows a confirm box when the user clicks on a paging button. If the function returns true, the client side code should run. If the function returns false then nothing else should run. I have been successful with getting this to work for the "Go" button but it won't work for any of the other paging buttons because I have "UseSubmitBehavior" set to false. Can anyone think of a way to get this to work with the other buttons?

Thanks in advance for the help.

<asp:Button ID="btnFirstPage" runat="server"  Text="<<"  OnClick="PagerClicked" OnClientClick="return unsavedChanges();" UseSubmitBehavior="false" />
<asp:Button ID="btnPreviousPage" runat="server"  Text="<"  OnClick="PagerClicked" OnClientClick="return unsavedChanges();" UseSubmitBehavior="

Pass string to Javascript function from code-behind...

  

Hi!

I'm trying to send a error message to a javascript function from code-behind, but it's not working. When the javascript is executed the output error is: [object Object]

Here's my Javascript:

function Error(error) 
{
            document.getElementById("<%= errorText.ClientID %>").innerText = error;
}


And my C#:

try
{
        (...)
}
catch
{
        textError = "This is not working!!!";

        ScriptManager.RegisterStartupScript(Page, this.GetType(), "Error", "javascript:Error('" + textError + "');", true);                
}


Even if i pass the string instead of the 'textError' variable i still get the same error :(


Can anyone help me?

Unable to call javascript function through button's click

  

Hi,

i have a javascript function that is placed in a separete file.There are some other functions also.

On a Button's OnClientClick i want to call a javascript function, but it is not called.When i put the same function in my aspx page that function is called. So how can i call that function which is placed in another .js file.

I  have taken some other controls like radio button , that is working fine when i call some functions  that is placed in the same .js file.

I have written like this in Button's OnClintClick property:

<asp:Button
                   ID="butSubmit"
                   runat="server"
                   Text="Submit"
                   OnClientClick="submitForm()"
                   
                   />


 


Launching a javascript function from code behind

  

I need to build a javascript fucntion from the server side code-behind. I can't do it with setting any attributes, because the launching of the script depends upon a variable inside the server side text changed event (which at that time is too late for an attribute setting).

From inside that server event, if a certain value is retrieved, I should call the javascript fucntion. The function to be built should look something like this.

function openPri1Srch(btn, id, wind) {
    var hdnbfiPriCount = document.getElementById("hdnbfiPriCount");

    if (hdnbfiPriCount.value != "1") {
        curRow = btn;
        var oWnd = radopen("../xref/billingPatientDemoInsuranceSearch.aspx?id=" + id, wind);
        oWnd.setSize(1000, 400);
        oWnd.maximize();
        oWnd.center();
        oWnd.add_close(OnPriClientClose);
    }
}

I just don't know how to actually build the function (syntax with the quotes, etc.) I will have the follow

Hi I am using the FullCalendar plugin and I am wanting to load events from the db to the page.

In my codebehind I have a string built up of the events which need to be included.

And I need it to be inserted into the javascript function in the position shown below:

Any help???

                center: 'title',
                right: 'month,agendaWeek,agendaDay'
