How to make a linkbutton onclick with parameters


<asp:LinkButton ID="lnk_productImage" runat="server" Text="select" OnClick="viewProductImage('<%#DataBinder.Eval(Container.DataItem,"Id") %>')" > </asp:LinkButton>


protected void viewProductImage(object sender, EventArgs e, int id) { //Load Product Image }


I see you're using a repeater, so you probably could use this code:

In your repeater template:

<asp:Repeater ID="_postsRepeater" runat="server" OnItemCommand="_postsRepeater_ItemCommand"> <ItemTemplate><asp:LinkButton ID="_postDeleteLinkButton" runat="server" CommandName="DeletePost" CommandArgument="<%# ((Post)Container.DataItem).ID %>">Delete</asp:LinkButton></ItemTemplate> </asp:Repeater>

Then handle the repeater's ItemCommand event:

protected void _postsRepeater_ItemCommand(object source, RepeaterCommandEventArgs e) { if (e.CommandName == "DeletePost") // Replace DeletePost with the name of your command { // Get the passed parameter from e.CommandArgument // e.g. if passed an int use: // int id = Convert.ToInt32(e.CommandArgument); } }


Use CommandArgument property of linkbutton to pass parameters.

CommandArgument property:

Gets or sets an optional argument passed to the Command event handler along with the associated command name property.
