programmatically click a button vb.net

I'm not entirely sure what it is you want to do, but here are a couple of options:

For simulating a click on an HTML button (clientside), you could use JQuery:

$("#mybutton).click();

or

$("#mybutton).trigger("click");  

Of course you'll need to attach the handler to the button in your

$(document).ready(function(){
    $("#mybutton").click(function(){
        //do something
    });
});

If you want to simulate a click on an ASP.Net (serverside button):

You can simulate a button being clicked by calling the function the button's Click event is bound to:

<asp:button runat="server" id="btn1" Onclick="btn1_Click" Text="Click Me" />

protected void btn1_Click(object sender, EventArgs e){
    //stuff that happens when you click the button.
}

and then in code:

e.g.

btn1_Click(null, new EventArgs());

Responses to an earlier question go into more depth on this subject.

UPDATE:

From the serverside the best you could do is reload the page and then get it to generate a script to make the necessary function calls.

Does the button have to be an or can it be a regular HTML button? If the latter just wire it up to a function that makes the call to modal by its Id.

If the former, you'll need to add a CssClass to the declaration and wire it up to a function via its class - $(document).ready(function(){ $(".myButtonClass").click(function(){//Wired-up by class $("#myButtonId").click(function(){//Wired-up by html ID $('#MyModalContent').modal(); return false; //you might need extra code to prevent the event propogating. });

Consider using the WatiN framework. It allows browser ui automation easily.

Example:

browser.Button(Find.ByName("<buttonname>")).Click();

Alternatively, you could use ClientScriptManager.RegisterStartupScript() to call client script from code-behind.
