How do you call a codebehind/class method from a gridview in an aspx page? Also, I need to pass the value of databound column to that method.
<asp:BoundField DataField="Precision" />
<asp:BoundField DataField="MyNumber" DataFormatString="FormatHelper.Format(MyNumber, Precision)" />
C# or VB.NET are welcome. I have an <%#Eval("FirstName")%> in the aspx page, I want to replace "FirstName" to <%#Eval(employee.FirstName)%> but "employee" object is instantiated in the codebehind like this:
Public employee As New Employee How can I call this object in the aspx page? Should I can create an "employee" in the aspx? if so, how to do that.
I have a parent page and child page, both aspx. All is working, but now I would like to close child page, if user leaves child popup page and goes back to parent page and clicks on something else like page index of Gridview. I CANNOT close popup child page if user goes to another app, or some other location, I only want to close if something on parent page is changed.
I have the PageIndexChange Event set up for other purposes, I would just like to add some functionality, perhaps a script manager to close the child popup page if the Gridview index is changed, java or another way which ever works best.I think I might also need to check if the child page is even open.

In my asp.net project, I have two particular aspx pages (lets say PageA.aspx and PageB.aspx)
In the codebehind PageA.aspx.vb, I want to call "Sub GetDefaultValues()" which happens to be in PageB.aspx
Update:PageB.aspx has textbox controls that contain default values (which are being read in Sub GetDefaultValues). Those default values get populated into the textboxes of PageA.aspx (based on certain conditions)
Is there a way to do that?

I have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.

What I want is, I am creating a table in the database on the fly in the code behind using the below code(in VB).Now my main problem is I want to display this table which is created in step 2 of a wizard, in step 3 using a GRIDVIEW. But as we all know a GridView needs a sqldatasource for values to be displayed, however what I need for achieving this is dynamically assign a datasource to the GridView, but I am not figuring out HOW?

I have an aspx page with three web controls: one to control the List Users page, one to control the Edit Users page, and one to control the Add User page. I have discovered a method for accessing these elements, but it seems to be limited. Here is what I have done:

'set selected user from gridview.

I am trying to check all the checkboxes on a webform (aspx) page, which is inside a master page,depending on the ID of the checkbox.

I have one page with two dropdownlists with different IDs and in my codebehind I have two distinct methods, one for each dropdownlist, with distinct names and handlers.BUT, in my codebehind, only one dropdownlist calls it's method - and sometimes it calls both methods! - while the other dropdownlist never calls its method.I tried cleaning the infamous "Temporary ASP.NET Files" folder I tried rebuilding the solution but the problem persists?

View 1 RepliesRight now, I am working on taking a self-updating excel sheet and building small html blocks from the sheet which will fit into a JQuery list sorter and image viewer (tags and tags ). The problem I am running into is that by placing the code onto the page in a literal the html is never placed on the page, it is generated on the fly, thus the JQuery handler can not hook the tags and the sorter does not function. I know there is a way to add variables from the code behind with <%=var%>, but I need to add a large number of variables that will change as the excel sheet updates, which is why I am using a code behind function to generate a glob of instead of rewriting it constantly.Here is my current Code behind function that generates and inserts into literals:
Dim count As Integer
count = ds.Tables(0).Rows.Count
