问题 HTML : <asp:LinkButton ID="lnk_productImage" runat="server" Text="select" OnClick="viewProductImage('<%#DataBinder.Eval(Container.DataItem,"Id") %>')" > </asp:LinkButton> CodeBehind: protected void viewProductImage(object sender, EventArgs e, int id) { //Load Product Image } 回答1: 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

问题 I am creating dynamic TextBoxes in a page by clicking a LinkButton.

问题 I have a "UserDetail" table in my "JobPost.mdf". I have a "Gridview1" showing the column from "UserDetail" table,which has a primary key "UserName". This "UserName" is originally saved using Membership class function. Now I add a "Delete" linkbutton to the GridView1. This "Delete" is not autogenerate button,I dragged inside the column itemtemplate from ToolBox. The GridView1's columns now become "Delete_LinkButton"+"UserName"(within the UserDetail table)+"City"(within the UserDetail table)+

问题 I have a LinkButton inside a GridView (via an TemplateField). No matter what I try, the LinkButton will not invoke its event handler. I have tried both: A traditional event handler ("OnClick") A OnRowCommand event handler at the GridView level. In both cases, I've debugged and it doesn't even catch the event handler. If I move the LinkButton out on the page (so it's not in the GridView), it works fine, so I know the syntax is right. Here is the "traditional" method: <asp:TemplateField>
