View 5 RepliesI have a server control that performs some logic. I'd love to provide a default implementation of this logic in the code of the control, but allow a developer to pass an alternate implementation of this logic in as a delegate, if they wish.
So...
<prefix:MyControl FooLogicMethod="MyUtilityClass.MyFooLogicMethod" runat="server"/>
If they don't specify this, I'll use my default method. If they do specify it, I'll use the method they passed in.
Can I do this as a delegate, or do I need to reflect it?
I want to pass to my control a value to one of its parameter of type DropDownList. Something like:
<uc1:MyControl Id="01" runat="server" OtherControl="ddl1" />
Where "ddl1" is a DropDownList defined in the same page my control resides. How to create this kind of property?
I have two comboboxes and would like pass selected value and text to the server method (RadComboBoxItemsRequestedEventArgs) when the first combobox selected index changed.

I'm interested in identifying a means to verify the server-side validation is performing as expected, but need to bypass the client-side validation being done using ASP.NET validation controls. To test this, I've tried using the form Poster add-on to Firefox that allowed me to get/modify the page contents and post it, but the .NET framework interpreted the submission as harmful and threw an application error ("A potentially dangerous Request.Form value was detected from the client").I've created a WinForm that includes a WebBrowser control and I'm able to manipulate the contents of the web page and invoke the button click, but am interested in seeing how to allow a postback with invalid input values. I don't want to assume the server-side validation works (even though I do check if Page.IsValid on the server on postback).This submits the web form in the WebBrowseer control and the expected client-side validation fires:
extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click");
This is how I've manipulated some of the page contents (this just prevents submission):
mshtml.IHTMLDocument2 doc = extendedWebBrowser1.Document.DomDocument as mshtml.IHTMLDocument2;
string html = doc.body.innerHTML;
html.Replace("Page_ValidationActive = false", "Page_ValidationActive = true");
doc.body.innerHTML = html.ToString();
extendedWebBrowser1.Document.GetElementById(formButtonName).InvokeMember("click");
I have a gridview which I databind to EntityModel
This typically looks like
something a
something b
companyID
on Login I get and set the compnay which has the ID so what in essence I want to do is on databind set the Where clause of data source to what the server side paramter for company ID is.
This may be elementary user control stuff, but I can't get it to work.
How can I pass the Membership.GetUser.UserName variable (or any variable) through a user control parameter at load time?

The only thing that I was able to do was to create the User Control object in the code behind and then add it to the page. Although that works, it doesn't seem like the correct way to program.
I have one more question. How can I use a column in the stored prcedure and pass it to a parameter in the code above?

I have a loop in JS, and I want to pass each parameter in that loop to a function in ASP.NET in the codebehind.
something like that:
for (var i = 0; i < elements.length; i++)
{
}
And I want to pass a function in <%%> the elements[i].
How can I do that?
how can I pass a client side (JS) value in server side (C#)?
e.g.
I have a generated table (after uploading images) and it contains images and I want to select the image and throw the ID back in server side.

I have a class constructor which accepts a Listbox.
[Code]....
I need to be able to pass another control type and execute the exact same logic in one of the methods... Seems like a use for Generics... I'm not so sure about the syntax... The type of control that I will pass is a rad combo box which has many of the same properties of the listBox control. However, RadComboBox does not inherit from listBox or dropDown so I am unable to cast. When changing the signature of the constructor to As RadComboBox as well as the property and field the method works as expected. I am trying to avoid duplicating code here.
protected void btn_showReport_Click(object sender, EventArgs e) {
try {
ReportParameter Comp_Name = new ReportParameter();
Comp_Name.Name = "Comp_Name";
ReportViewer1.ProcessingMode = ProcessingMode.Remote;
ReportViewer1.ServerReport.ReportServerUrl = new Uri("http://dell-pc/ReportServer");
ReportViewer1.ServerReport.ReportPath = "/Companies Report/Companies";
[CODE]..
the above code is in "reportpage.aspx" when I click on it the company report is shown according to the parameter "Comp_Name"
I want to show report in "reportpage.aspx" according to parameter name passed from another .aspx page, how to do that?
In a GridView, I am using ItemTemplate section for multiple editing. I am using ClientValidationFunction property of MaskedEditExtender to run a client side function. Let's call it MyClientFunction . How can I pass an ID of a control found in the gridview row to my MyClientFunction?
I know how to do it via RowDataBound as follows: Is there a way to wire it up in ClientValidationFunction property?
Dim NewDte As TextBox
Dim PrvDte As Label
NewDte = CType(e.Row.FindControl("EditReadingDate"), TextBox)
PrvDte = CType(e.Row.FindControl("lblEditLstRdgDte"), Label)
NewDte.Attributes.Add("onkeyup", "javascript:ChkDteMultiple('" & PrvDte.ClientID & "')")
I have an ASP.NET VB website in which I am using the Membership functionality to authenticate users. I am doing this through the Login control on the HTML page. I have working that it will authenticate the user and then opens a welcome screen in which I have a button they can push to open a Reports.aspx page. On that page I have a dropdown box that is being populated from a datasource connection query to my SQL Server database table. It is a hard coded query but want it to query the table off the username text value that the user provided on the login (i.e. select <something> from inventory where username = <username>). I have not behind code but only HTML at this point. Here it is ...
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Login.aspx.vb" Inherits="Login" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

I have a hidden variable and its value is being updated using javascript(client side) which I make a call from server side code. After making the call I am not able to retrieve the updated value from Server side variable. I went through this forum [URL] but not able find a way how to implement functionality with IFRAME. I am trying to call the client side code and retrieve the updated value from server side in page_load event.
View 5 RepliesI've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?
