Creating Buttons and text fields dynamicaly

Hi,

I want to create several textboxes and buttons in my page.
Each button has a unique ID, an they all must call the same function, but will behave defferently, like by passing a parameter...

Do you have any idea how i can do that ???

hmmm. It sound slike you need to create a fucntion and pass parameters to it on the button click

Code:

---

Private Sub btnExport_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExport.Click
  Dim strFileName As String = "test.csv"
  Dim strFileLocation As String = "C:\Inetpub\wwwroot\reports\"
  Export(strFileLocation & strFileName, dsResults.Tables(0))
End Sub

Dear davebat;
This function only runs at a button click, but i did not understand the part which submits the parameters..

I didn't get this part

Thanks

Why not assign a different CommandName property to each button and then you can use this in the shared click handler.

Hi...
Can you guide me how i can do that ???

Thanks

First create button and assign a CommandName and event handler.

Code:

---

Button btnNew = new Button();
btnNew.ID = "btnNew";
btnNew.Text = "Click me";
btnNew.CommandName = "Button_Clicked";
btnNew.Click += new EventHandler(btnNew_Click);

---

Obviously you'll have to add this to a control collection somewhere to make it appear on the page.

Then within the event handler you can access the CommandName property:

Code:

---

void btnNew_Click(object sender, EventArgs e) {
if (sender.CommandName == "Button_Clicked") {
//The dynamic button was clicked!
}
}

Wow...
Thanks a lot dj4uk

Thats exactly what i needed :thumb:

One more thing....

How can i place them in my webpage... ??
Can I add them as to a cell in a table object ??
:blush:

Add placeholder controls wherever you might want to add controls. If you don't add anything then nothing is displayed on the page.

To add a control just do the following after you have created the control dynamically.

Code:

---

phldNew.Controls.Add(btnNew);

---

where phldNew is the placeholder control ID.

HTH!
