View 1 RepliesGot a little dilemma I could use some guidance on. I'm trying to call an Interface method that resides in my Business Layer from within the template of a gridview in the same manner as below:
<%# GetEmployee(Eval("EmpId"))%>
i.e. it reads as follows:
<%# BusinessLayer.IEmployee.GetEmployee(Eval("EmpId"))%>
I'm actually getting the following error:
"An object reference is required for the non-static field, method, or property"
Which makes sense as I haven't instantiated as instance of the Interface. So the queston is how do I do it?
Can we call a Method that exist on a aspx page through Web Services.

I am just learning ASP.Net and i am more using C# as code behind than vb.I am trying to call a method of the code behind (file.aspx.cs) from the (file.aspx).I know how to do it the easy way:- create a button from ASP.Net and double click on it than the property "onclick" will be linked to the method.But i don't know how to do it from a query:
- By example, from an Access database,i use the syste, [using System.Data.OleDb;] and i made a query and display it into a standar object named "Table" which has rows (tablerow) and cells (tablecell) and the cells have one of their properties which is "Controls" where developers can add button (regular button, image button, link button, etc). With i display the buttons from the database, i can not call a method from code behind! I can't either use their properties "onclick" to call i method i created in the code behind.Is there a way to do it ?

How to make a span tag behave exactly like an asp:button (ie) using its onclick method to call a codebehind method..

My pages base on master and content pages and in content pages I have Multiviews; inside Multiviews I have RadComboBoxes.Two of my RadComboBoxes are parent and child, like country and city dropdowns. Therefore in code-behind I put some code in the OnSelectedIndexChange event of parent RadComboBox for filling its child; I use a hidden field for country id and sql datasources (stored procedures). Meantime parent and child combo boxes are in an update panel.For doing this job i set the autopostback property of parent combobox to true,but I do not want that autopostback=true because of some focus problems that I coded with jQuery.So I want to convert the OnSelectedIndexChange event in code-behind to a method and call it in jQuery (in change event or something like that of parent combobox). How can I do this?

We're having a problem in our ASP.Net application where the Crystal Reports engine leaves garbage .tmp files in the server's Temp folder after generating reports for the users.So we're trying to figure out how to run the .Close() and .Dispose() methods on the Report object, but we're finding that the code never gets run after the export occurs.
MyReport.Report.ExportToHttpResponse(ExportFormatType.PortableDocFormat,
this.Response, true, "My_Report"); [code]...
Breakpoints set on the last two lines never get hit, and we've also tried putting other code there to test the processing. None of it runs. (I've also seen this question on other sites with similar code, but no answers)I assume the ExportToHttpResponse method is returning a file stream (PDF) to the user at that point, ending the processing so the rest of the code doesn't get run. If that's the case, how do we get CR to perform a cleanup on the temp files, which the Close() and Dispose() methods are supposed to do? Do we have to implement a manual after-the-fact cleanup?
I have a few custom composite controls that set their cssclass only when calling their ApplyStyleSheetSkin method.I worked around this by creating a function which recursively walks through all controls on a page and calls that method, but I was wondering if there isn't a way to do this automatically?
