Using __doPostback in C# can be achieved by calling the __doPost

I attempted the following code:

Page.ClientScript.RegisterStartupScript(this.GetType(), "postback", "<script>$(document).ready( function() {__doPostBack('ctl00$ContentPlaceHolder1$PrintExcemptionsButton',''});</script>", false);

Unfortunately, the issue lies in the fact that the code itself does not trigger a postback and click the PrintExcemptionsButton.

My goal is to simulate a button click programmatically using the __doPostback method in C#.

I would greatly appreciate any assistance with this matter.

c#javascriptasp.net

Answer №1

To initiate the desired postback action, you can trigger the .click() event on your button:

Page.ClientScript.RegisterStartupScript(this.GetType(), "postback", "<script>$(document).ready( function() {$('#" + PrintExcemptionsButton.ClientID + "').click()});</script>", false);

Alternatively, instead of this approach, you could directly call the OnButtonClick() function within your Page_Load method in the codebehind.

Answer №2

 function triggerAssignButton() {

 __doPostBack("<%=btnAssignment.UniqueID %>", '');
}

<asp:Button ID="btnAssignment" runat="server" Text="Click to Assign" CausesValidation="false"                                                        OnClientClick="return triggerAssignButton();" OnClick="assignButton_Click" />

Follow this example for usage.
