I have a code behind page that has several method; one of them is a page method.
[WebMethod]
public static void ResetDate(DateTime TheNewDate)
{
LoadCallHistory(TheNewDate.Date);
}
protected void LoadCallHistory(DateTime TheDate)
{ bunch of stuff }
The method LoadCallHistory works fine when the page loads and I can call it from other methods inside the page. However, in the web method part, it gets underlined in red with the error "an object reference is required for the non-static field".
How do you access functions from the page method part of the code?
I have made 3 web controls which need to be accessible between eachother. First control is main control (controlA). Other 2 controls (controlB and controlC) are referenced in controlA. Now i need to access function from controlC and call it in controlB. I tried adding new reference, but it doesnt work the way I want it.
ControlA is main control and it is merely a table to hold other 2 controls in place. I can access both controls from controlA, but since I need to modify controlC due to drop down menu in controlB i can't force controlA to respond to event in controlB every time it occurs and affect controlC. Or can i? :)
So whenever the event (SelectedIndexChanged) of drop down menu occurs in controlB, I need to set up/change controlC. Problem is, I don't know how to call function from controlC. It may sound very simple to solve and i tried to make a new instance of controlC class in controlB my webpage just wouldn't load.
I have 2 web pages edit.aspx and webmethods.apx. In edit.aspx there is some jquery code to get some data :
[Code]....
With this I try to get a Json object from the webmethods.aspx page :
[Code]....
I get an error back that says "Parser Error", I even did put an breakpoint on the webmethod but it is like it's never triggered. Is my url wrong if I'm in the following url :
I am doing an AJAX call back to a WebMethod but in the code behind webmethod I cannot use any of the constants at the to of my form. What I want is to gain access to sessions and my sql connection string.
Aplogies if this has been discussed before but I couldn't find an answer.
I'm trying to use jquery/Ajax to access some webmethods in my codebehind. This is fine, but I would in my function like to reference a placeholder (phStory in the code below) on my page and also load a usercontrol into that placeholder.
Unfortunately I get the message: "An object reference is required for the non-static field, method, or property 'TestControls.phStory' " and similar for the usercontrol. Does anyone know how I can still access my placeholder and usercontrol from within this.
It has to be stati as it's a WebMethod but this then throws up these errors.
I have a JavaScript-based timeline which needs to use data from an SQL server. The queries and the JSON conversions have been worked out in the form of C#.NET functions within a code file related to an .aspx page. So for a complete newbie to ASP.NET, how do you set up a function call like this from JavaScript?I would love it if someone had some simple example code I could learn/get some pointers from.Edit: I am using .NET 3.5
getting the Parameters declared in an sql function in the C# code. We can actually get the parameters from a Stored Procedure by giving SqlCommandBuilder.DeriveParameters
Similarly is there any way to get the Parameters from the SQL Function.
I have a service that works great on my development box. It uses JQuery to hit my web service, and then the JSON results are sent back.
The web service is located on our basePage.cs. We didn't want to put out an external WebService for this. Our on beta box something different is happening.
The web page seems to be trying to call the web method correctly - the JSON data is being sent... but the server doesn't seem to know it's a webmethod. here's my service function (it's in our basepage.cs which inherits from Page).
I created a user control in Asp.Net which I populate with <asp:Table id = "...." /> this table has columns that contain dropdownlists, textfields and other web controls. In the code behind I am not able to access these web controls, is there a way I can access them. or I shouldn't be doing that in the code behind of the user control? here is my ascx code markup:
Seem to be having trouble getting ahold of an asp:Image I placed on an .aspx page in my code behind. I'm trying to set the Visible property to "true" programatically.
Now that I put this html inside a Tab containe (subpanel) the Page.Request.Form["Name"].ToString() fail, actually while I was debugging I could not find this element inside Page.Request.Form.
maybe there is another way of accessing the Html element from my c# code?
I have a few pages in my web application where I would like to be able to use the code-behind of a master file, but not 'inherit' any of the other stuff like asp/html markup etc.
I know in standard VB.Net development, you can access any form field from within a module class but I'm not sure how to do it using Web Forms.Here is my scenario:I have a Module.vb where I am putting all my Database Functionality. In each of my functions, I'm using a Try Catch construct.
i have a link button which i have created dynamically and added it to a div i want to access this link button in some other function in code behind how to do this
I need to display a control consistently across a set of pages. So I'm using a MasterPage to do that in ASP.NET/C#. However I also need to programmatically access this control, mostly provide options to view/hide depending on whether the controls checkbox is clicked.
Here is the Source for the MasterPage
<div id="verifyInitial" runat="server"> <asp:CheckBox ID="chkInitialVerify" runat="server" oncheckedchanged="chkInitialVerify_CheckedChanged" /> I agree that my initial data is correct. </div> <div id="verifyContinuous" runat="server"> <asp:CheckBox ID="chkContinuousVerify" runat="server" oncheckedchanged="chkContinuousVerify_CheckedChanged" /> I agree that my continuous data is correct </div>
Now in the code behind I want to perform the following operations. Basically if a person clicks on the checkbox for the initial div box, then the initial box disappears and the continous box shows up. However it seems that the code behind for the MasterPage does not activate whenver I click on the checkbox. Is that just the way MasterPages are designed? I always thought you could do add some sort of control functionality beyond utilizing the Page Load on the Master Page.
