LinkButton Handles OnClick Equivelent in C#
To handle a Linkbutton onclick in VB.NET the LinkButton is declared and a handler sub declared:
<asp:linkbutton id="cmdAdd" runat="server" ResourceKey="Add" BorderStyle="none" CausesValidation="true" /> Private Sub cmdAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAdd.Click ::: ::: End Sub
C# doesn’t support the VB.net handles on click, the function is simply declared.
The LinkButton declaration is given below. Unlike vb.net there is no WithEvents part of the declaration.
protected global::System.Web.UI.WebControls.LinButton cmdAdd
Explanations of the above:
- protected – Used to restrict access to the code to the same class.
- global – Used to clarify that the object is taken from the global namespace as opposed to the current one.
- :: – This operator, positioned between two indentifiers, is used to look up an identifier.
- cmdAdd – name of the LinkButton
Looking in the .ascx presentation file the link button is declared as:
<asp:linkbutton id=”cmdAdd” runat=”server” ResourceKey=”cmdAdd” CausesValidation=”true” />
Begin the OnLoad, and include reference for the LinkButton
protected override void OnLoad(EventArgs e) {
base.OnLoad(e)
try {
cmdAdd.click += new System.EventHandler(cmdAdd_Click);
Then later in the code there is the cmdAdd_Click function:
private void cmdAdd_Click(System.Object sender, System.EventArgs e) {try {
// actions here for the function
