I am adding an update panel dynamically.I am creating a dynamic table also and I have a button control in the table. when I click the button, I just want the table to be loaded again. So, I added this table to the update panelUpdatePanel1.ContentTemplateContainer.Controls.Add(table);I added the update panel to the page placeHolder1.Controls.Add(UpdatePanel1);But when I click the button, the whole page is getting loaded.How can I solve this?
