Question

I have two buttons with on click functions

The 1st one gets assigned a variable when Clicked.

How do I get my second button to get the variable from the 1st button when I click button 2?

It doesn’t seem to work. As the second button doesn’t recognise the Variable.

Thanks

EDIT:

Just to clarify My code is generating a pdf. button 1 selects the url of the template to use. and in button 2 (the one generating the pdf) I want it to get the variable set from button 1 so it knows what template to use.

EDIT 2:
My code does work but only when I’m not using the ajax update panel. it seems that the variable I’m trying to set doesn’t get set with AJAX

Answer 1

Your Button have Id, you get this button with his Id

Nota : You can add runat=”server” in order to visualize in server side

<asp:Button id="Button1"
           Text="Click "
           OnClick="Btn1_Click" 
           runat="server"/>

<asp:Button id="Button2"
           Text="Click "
           OnClick="Btn2_Click" 
           runat="server"/>

void Btn2_Click(Object sender, EventArgs e)
{
    Button1.Text = "test after click on button 2";

    Template = ...;//Set your value
}


void Btn1_Click(Object sender, EventArgs e)
{
    Button2.Text = "test after click on button 1";

    //Here you can get your value after post.
    var result = Template; 
}

It’s not subject but in delegate you can also get objet button by passing on sender argument.

var button = sender as Button; //You get button who raise event

In order to manage Template Path property.

public string Template
{
   get
   {
      if(ViewState["Template"] != null)
      {       
         return (string)ViewState["Template"];
      }
   }

   set{ViewState["Template"] = value;} 
}
