I have got many buttons in my Application Form. And I would like to check every buttons text (compare). How can I achive that ?
for (i = 1; i < 30; i++)
{
if (this.button1.Text == "Hello") //here is PROBLEM
{
//..some statement
}
}
So next time this.button1.Text must change to this.button2.Text and so on...
this.button[i].Text not working.
Buttons are not arrays. Each one is a discreet object, and a child of its container.
Ideally, you need to build a collection (array, list, whatever) of the buttons and iterate through that collection, rather than using an index variable (i).
Here's a good approach: https://stackoverflow.com/a/3426721/820068
This is a correct syntax:
foreach (Control button in this.Controls)
{
if (button.GetType() == typeof(Button) && button.Text == "Hello")
{
//..some statement
}
}
I'm quite sure that this is a windows form. And in windows form you can iterate the controls like this.
foreach (Control c in panel.Controls)
{
string cType = c.GetType().ToString();
// check all buttons
if (cType == "System.Web.UI.WebControls.Button")
{
if(((Button)c).Text == "Hello")
{
}
}
}
So what the code does is to iterate all the controls inside a panel and check each control if it's type is a button.
Update: As Wesley said, much better approach for the condition is to implement it like this
if (c is Button && c.Text.Equals("Hello")) {
System.Web.UI.WebControlsfor (int i = 1; i < 3; i++)
{
var buttonName = "button" + i;
Button button = this.Controls.Find(buttonName, true).FirstOrDefault() as Button;
string text = button.Text;
}
try this code.
