dgw programmatically call a method

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :Windows Application
I have a method on a dataGridView, which is fully addressed like this: private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e) { //code }   I would like to access to this method programmatically, without mouse double click. And I have to pass a parameter of a row index. I have tried to pass an integer, but I got an error (cannot convert from 'int' to 'System.Windows.Forms.DataGridViewCellEventArgs), like: foreach (DataGridViewRow row in dataGridView1.Rows) { if (row.Cells[0].Value.ToString() == _myCellName) { dataGridView1.Rows[row.Index].Selected = true; dataGridView1_CellDoubleClick(null, row.Index); //here Im trying to pass a value for the upper method break; } }   When the upper method (dgw_CellDoubleClick) is programmatically called, I would like to call an "e", with: if(e.RowIndex > 0) { //code } So what to pass from to the method, that will work?

Hi All,

I am first time working on web service and Javascript and trying to call a Web Method (web service) on a button click in Javascript.

What I want to achieve is as followed: When the button is clicked, call the web method, get the return URL value and store it to a session variable, the redirect the page to another page. However, this works only when the internet traffic is fast, it give me error when internet is slow as the Javascript is executed much faster than the web service. Is there any way to handle this?  Would be much appreciated for your help! Cheers.

WCF Basic Http Binding - Two server requests per method call

We have a service that uses BasicHttpBinding/Transport Security/Windows Authentication and is hosted in IIS. I have created a unit-test application in VSTS and whenever we test a WCF method, Fiddler records two calls. 1st call - No authorization token is sent. The WCF service returns a 401 error - Unauthorized: Access is denied. Http headers as sent in the request given below. POST http://localhost/AccountScreen.svc HTTP/1.1 Content-Type: text/xml; charset=utf-8 SOAPAction: "IAccountScreen/RetrieveAccountDetails" Host: localhost Content-Length: 243 Expect: 100-continue Connection: Keep-Alive 2nd call - Authorization token is sent and the WCF service returns the expected response. POST http://localhost/AccountScreen.svc HTTP/1.1 Content-Type: text/xml; charset=utf-8 SOAPAction: "IAccountScreen/RetrieveAccountDetails" Authorization: Negotiate Host: localhost Content-Length: 243 Expect: 100-continue I am not able to figure out why there are two calls made to the server in the first place and what is the significance of the first call. Any thoughts?

Is there a way to save a refernece to a method in a Tag property and call that method directly from

Hello, Here is a tough one, probably only answerable by someone who really knows his stuff. In the WPF program below, I would like to completely eliminate the necessity of the "LoadIt" method.  The way I'd like to do it is by saving the address ( or some other appropriate information ) of the method to be called to add a Person or Pet to the Expander's Tag.  Then, when the Add button is clicked, the Expander's Tag is read and the method saved therein is called.  The comments in the code below give the gist of what I would like to happen, if such is possible.  The actual application this will be applied to has many groups to add, thereby making the switch statement in the "LoadIt" method huge.  That is what I would like to avoid. Here is the fully functional test program: XAML: <Window x:Class="MethodAsParameter_01.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Loaded="Window_Loaded" Title="MainWindow" Height="350" Width="525"> <Grid> <ScrollViewer> <StackPanel Name="Root" Orientation="Vertical" ButtonBase.Click="Root_Click" /> </ScrollViewe
