View 4 RepliesI've scenario where I want to insert data into database without post back. there are around 12 to 13 fields which i need to insert. I'm passing DTO from the client side which is actually Json object. Now the problem which i'm facing is how to convert that Json object which i got in webservice to the "class" (in my case class name is User) object.
[Code]....
In the above case AddNewUser method takes the object of User class. But i'm getting casting error. So how do I convert Json object to the "User" class object?
I have an existing class for an input, is it possible to add an additional class for the object in C#.net, instead of doing a if/else and not having a preset class on the object in the first place?

View 5 RepliesI have a asp.net page titled EstMaterials.aspx with a gridview that fills from a SQL table based on a parameter passed to it. The code for calling the form is below.
<asp:UpdatePanel ID="upAddMaterials" runat="server">
<ContentTemplate>
<div id="AddMaterials" style="text-align:center">
<asp:Button ID="btnDecoy" runat="server" Text="Decoy" style="display:none" />
<asp:LinkButton ID="lbAddMaterials" runat="server" Text="Add Materials"></asp:LinkButton>
[code]....
I have an a button field set as a link in a gridview. When the user clicks on the link it should open the "EstMaterials.aspx" page with a gridview listing the materials required for this job. If I do not have a parameter i.e, ScheduleWeek.oJob.JobSeqNbr, the gridview fills fine. However, with the parameter listed the gridview does not fill. It appears the form opens without ever looking at the parameter being passed.The page load event is below.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not IsPostBack Then
If Not IsNothing(ScheduleWeek.oJob) Then
Dim tbl As New DataTable

still really new to this, so I apologize if I explain my problem poorly. I'll do my best.I used this method to add an "active" class to my main navigation on another site. Now I'm using it to change the background image for a div based on the current page.Problem is, it's not working in this case. When I view the source I just see the tag sitting sitting there like it wasn't compiled:

I have a website built that uses master page templates. In the master page I have a simple menu in a list. This is not dynamic (yet!).
I am trying to put together some code behind to write a simple css class to one of the menu links if the Request.ServerVariables("URL") is equal to the current page URL
I have no code written because everything complains when I try to come up with something. I was thinking of doing it using a switch function but am I over complicating things?Below is the simple menu with the class I am trying to write to the link:
<div id="nav">
<ul>
<li><a class="selected" href="Default.aspx" title=""></li>
<li><a href="" title="ThisPage.aspx"></li> [code]....
i have a list of contacts (generic list) and i bind a gridview to it, i get the list displayed on the griview that fine, now i'm trying to get a contact object when i click a button on the gridview (button is a template field) i want to get the object back from the generic list, not just an ID using data key names, even the index of it in the generic list will do.

I want to dynamically create asp textbox objects (as well as other types) with id's named sequentially up to a number the user decides but I'm having a problem getting my code behind to recognize these dynamically created objects. In "div1" below I manually create the objects and I have no problem getting the values in Sub cmdSaveDiv1Info_Click. My dynamically created code generated in Page_Load routine is identical to that in "div1" except for the textbox ID's yet when I try to retrieve the values the same way in cmdSaveDiv2Info_Click I get an "object reference not set to an instance of an object" error on the "Dim d2Year as String.." line.

I dynamically add the webcontrol in onInit or onload (page_load). it will cause the second post back and with the ispostback==false;
if first enter the page is no problem. but if I click on the some button. it will trigger postback two times.
first time: ispostback = true.
second time: ispostback = false.
the second time postback caused me headache because all my value has been initialized due to the coding like below:

View 4 RepliesI'd like to have a standard sql select statement that depending on user input changes to alternative one.
I've written code similar to this:
if (something is true....)
{
SQLdataSRC1.SelectCommand = "Select *... etc";
// where SQLdataSRC1 is the name of the sql select statement datasource in the front end code.
}
I've put this code in the onload event and in the SQL datasource event handler but still it gets ignored - and only the SQL select statement in the front end code is recognised.
What am I doing wrong?
