C# - How Toinclude A Self-reference To A Server Control In An External Method Call

Dec 14, 2010

I have an Asp.Net TextBox control whose enabled property I need to evaluate using a separate (from the code-behind of the containing page) class. The way I want to do this is:

<asp:TextBox ID="myTB" runat="server" Enabled="<% ToggleControl(this, "someBusinessValue") %>" ... />

The reason I need to pass a reference to the calling control is to see if there are other properties I may need to consider before disabling it. The 'this' keyword, however, refers to the page as a whole. And since my TextBox can be within a FormView, or GridView, I can't easily just get the control byexamining 'page.myTB'. I don't want to have to start ploughing through GridViews on the receiving class file just to retrieve a reference to the TextBox.Does anyone know how to refer to the control inline in this way?EDIT 1: This will need to be done to several different types of server control, such as ListBox, CheckBox, RadioButtonList, etc.EDIT 2: The best I've come up with so far is:

<asp:TextBox ID="myTB" runat="server" Enabled="<% ToggleControl(myGridView.FindControl("myTB") as WebControl, "someBusinessValue") %>"

C# - Reference An ASP Control Inside A Function Or Class Method?

Oct 7, 2010

How do you reference an asp.net control on your page inside a function or a class.
private void PageLoad(object sender, EventArgs e)
//An example control from my page is txtUserName
ChangeText(ref txtUserName, "Hello World");
private void ChangeText(ref HtmlGenericControl control, string text)
control.InnerText = text;
Will this actually change the text of the txtUserName control?
I tried this and is working

Call A Server Method When A User Closes The Page?

Jan 4, 2011

I want to remove a temp file from the server after the user close the page (I assumed I don't have this callback on the server by default),

I tried to call a server side method using (ICallbackEventHandler implementation) when the user close the page, but the problem is that the server side method doesn't fire in this case (closing the page), it only response if the page still opened. and I don't prefer to stop closing the page until the server response and send its call back to close the page manually.

C# - Undoing External Dll Reference From Tfs?

Sep 7, 2010

When I undo an external dll in TFS, it looks as though it worked because I can compile with no errors. However, if I look in the folder where the dll lives it still shows the newest dll, which technically would not compile if I just did an Undo.

So, my question is, where does the old dll live after I do an Undo?

C# - Add Reference To Method In Custom Control To A Child Control Created In That Same Custom Control

Feb 3, 2010

I have a custom control that is based off the gridview control located at: here The control is basically a gridview that automatically creates a column of checkboxes that can be used to "check" individual rows in the gridview. During the gridview's "CreateColumns" event, the "checkboxcolumn" is created dynamically. The checkboxcolumn also contains another checkbox in the header that is used to "select/deselect all" checkboxes in the column. Since the gridview does not automatically remember the state of the checkboxes in the checkboxcolumn on postback, I added a method to the control called "SaveCheckBoxState" which stores the indexes of the checked rows in Viewstate, and then I modified the "OnRowDataBound" event to check the Viewstate and reset the checkboxes based on the Viewstate.

I then added a call to "SaveCheckBoxState" in the gridview's OnSorting and OnPageIndexChanging events. This works great so long as I'm sorting or changing pages. However, I need it to update the viewstate everytime someone clicks or unclicks one of the checkboxes. At this time, the checkboxes are rendered with an onclick event that calls some javascript to highlight the row, or in the case of the checkbox in the header, to select/deselect all checkboxes. I need to call the "SaveCheckBoxState" method from the javascript used by the customcontrol, or I need to find a way to modify viewstate from javascript and perform the same action as "SaveCheckBoxState".

I've tried adding the "SaveCheckBoxState" to the onclick event declaration in the checkboxes, but when run, it simply tells me that the method is undefined. It doesn't exist in the parent page, and I don't think I should have to make an event for the parent page to pass the click to. It seems to me this should be all self contained within the custom control. Does anyone know how I can acheive this? Here is the code for the gridview OnPreRender event where the onclick event of the checkbox is set:

protected override void OnPreRender(EventArgs e)
// Do as usual
// Adjust each data row
foreach (GridViewRow r in Rows)
// Get the appropriate style object for the row
TableItemStyle style = GetRowStyleFromState(r.RowState);
// Retrieve the reference to the checkbox
CheckBox cb = (CheckBox)r.FindControl(InputCheckBoxField.CheckBoxID);
// Build the ID of the checkbox in the header
string headerCheckBoxID = String.Format(CheckBoxColumHeaderID, ClientID);
// Add script code to enable selection
cb.Attributes["onclick"] = String.Format("ApplyStyle(this, '{0}', '{1}', '{2}')",
// Update the style of the checkbox if checked
if (cb.Checked)
r.BackColor = SelectedRowStyle.BackColor;
r.ForeColor = SelectedRowStyle.ForeColor;
r.Font.Bold = SelectedRowStyle.Font.Bold;
r.BackColor = style.BackColor;
r.ForeColor = style.ForeColor;
r.Font.Bold = style.Font.Bold;

Architecture :: How To Add Reference To External Library

Sep 9, 2010

I have a Class Library Project that I'm using in another Web application project. I've noticed that this has just copied the Class Library DLL into the Bin folder of the Web Application, and also that if I make some changes to the Class Library and rebuild the project, I also have to rebuild the Web Application for the changes to take effect there.

This kind of defeats the object why I'm creating a Class Library as I'm hoping to put some generic functionality in there that will be available to a number of different web applications.

Iis7 - External References Slow Down Application (VS: Add Reference Dialog)?

Aug 6, 2010

I've noticed as my website gets bigger and bigger, the time my laptop takes to display my page is much longer then say a new projects with minimal references. I think there are two variables at play that affect ASP.NET warm-up time:

The quantity of external references The time it takes for a worker process to new() up each instance per worker process Additional time for the WCF objects as the ServiceHost may be in an external DLL First, are those the correct variables to take into account when considering ASP.NET startup time? Next, it appears that web.config may dispatch other objects for use with certain filetypes (*.svc, *.aspx, Windows Identity Foundation (WIF), etc. ). This too may cause delays in ASP.NET.

Last, my project is created as a "web project" not a "web site". Not sure if this has an impact. Is my theory full of holes, or is there something I can do to make development on a old laptop any better?

Web Forms :: Addition Of Label Control Short Circuits Image Button Call To JavaScript Method?

Jun 10, 2010

Adding a label control inside of a div will short circuit my image buttons onClientClick method call.

I have an Asp.net panel control. In that markup I have an image button control. My image button when clicked will not call my Java Script method unless the image button control is wrapped with a div or table <td> tag.

That is fine with me. However Just to the left of my image button I have a label control that must be on the same line/row of my image button. If I wrap both the label control and image control in a div or td tag then

my Java Script method is not called. So somehow wrapping the label tag with a div or td results in the short
circuiting of calling my Java Script method.

Why is this? I must have my label and image button control on the same line, so that is the requirement.

I tired using a span tag instead of a div, but that does not work. Below is my Asp.net markup code.

Call External Json Webservice From C#?

Jan 15, 2010

I need to make a call to a json webservice from C# Asp.net. The service returns a json object and the json data that the webservice wants look like this:

"data" : "my data"

This is what I've come up with but I can't understand how I add the data to my request and send it and then parse the json data that I get back.

string data = "test";
Uri address = new Uri("http://localhost/Service.svc/json");
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(address);
request.Method = "POST";
request.ContentType = "application/json; charset=utf-8";
string postData = "{"data":"" + data + ""}";

How can I add my json data to my request and then parse the response?

Javascript Refuses To Call ActiveX Method - Agrees To Call Another

Mar 4, 2010

I have an ActiveX object which extends some functions. I have a web page that loads the ActiveX object and calls its methods in Javascript. The ActiveX object has two method; the problem is that Javascript can successfully call one of them but fails to call the other; citing Object doesn't support this property or method which is nonsense because I made a VB6.0 application that successfully calls this other method, so the two functions are indeed extended correctly and performing their job. And yes, the Internet Explorer security zones are all set and everything, as I wrote above the javascript code can call one method but refuses to call the other.
