Web Forms :: Calling A Public Method On Aspx Page From A Usercontrol
Sep 7, 2010I have a problem with calling a method on a aspx page from a usercontrol.
The case is: I have 1 main page with 5 usercontrols, when something goes wrong in the code I want to display the error message in a Modalpopup Extender. I can create for each usercontrol a different modalpopup extender but isn't much easier when I make 1 popup in the aspx page. But the problem is: How should I call a method in the aspx page that open the popup?
I have search several hours on the internet but can't find anything useful.

AJAX :: Calling Webservices From Javascript: OnError Method, How To Identify The Method
Aug 26, 2010I have an application that has JS calling ASMX files to do asyncronous requests, using ASP.NET AJAX.
The problem is that I use always the same "onError" function, and now I don't know how to identify the method that rised the error, and it is giving me a lot of problems to debug errors. The parameter "data" of the onError method does not give enough information, for
example:
en System.ComponentModel.BaseNumberConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)
en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToType(Object o, Type type, JavaScriptSerializer serializer)
en System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams)
en System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)
en System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)
en System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)
Is there any way to know the webmethod that raised the error?
Calling Javascript From Codebehind?
Sep 16, 2010I have read many different resources but am still not sure if this is possible without using AJAX.
I have a javascript function that loads a div into a modal and says "Loading Please Wait" I have named this funciton loadingModal()
function loadingModal(url)
{
loadModal(...)
}
What I need to do is only trigger this after I have verified that the password and username are correct on the server side so:
btnSubmit_OnClick(object sender EventArgs e)
{
string usr;
string password;
if (verify(usr, password))
{
///// TRIGGER JAVASCRIPT HERE
LOAD TONS OF SESSION VARIABLES
.
.
.
}
else
Show Error and Definitely Don't ever mention still loading
}
I know I could just attach an onclientclick call to the javascript however it would load the loading modal even if it was an invalid username and password
Can I trigger javascript mid execution from the server side?

Forms Data Controls :: Pointing Button In Gridview To Another Method In Codebehind?
Jul 21, 2010is it possible to have a button that points to a method you have defined in codebehind, that passes in a record from the row as a parameter? for example, id.something like:
<asp:CommandField ButtonType="Image" EditImageUrl="/editbutton.jpg" ShowEditButton="True" OnClick="editRow(int id)"/>
it wouldnt necessarily 'edit' this row. i'd like it to instead load an editable grid corresponding to the id passed.
Web Forms :: FindControl On Default.aspx In MasterPage.CodeBehind
Dec 11, 2010I was wondering if it is possible to find a control in a standard web form that is using a masterpage.
So for example I have two pages - default.aspx and information.aspx. Both these web forms have label controls (lblDefault and lblInfo respectively). This information is stored in a database along with the content that the label controls should be populated with. Instead of having to program a method to retrieve the content text from the database for the relevent controls on these two pages would it be possible to find the controls in the masterpage codebehind file - something like Page.Form.FindControl("lblDefault")? So for each webform using a masterpage a check is done to see if any of the controls should be populated with content from the database.

Web Forms :: Calling Code Behind From Aspx?
May 5, 2010I often want to call a function in the code behind using the "<%# ... %>" syntax. Sometimes is works and sometimes it doesn't. It is also a difficult syntax to search for. Can someone point me at an explanation of the working (or not) of this syntax?
I just tried this:
<asp:TextBox
ID="TextBox1"
runat="server"
Text="<%# getBCSConnectionString() %>"
></asp:TextBox>
For example. The function is in the code behind (it returns a string). The TextBox is empty and no break point is hit in the function; it does not appear to be called.
