I am working with ASP.net project.Here I have loaded images into a grid.My issue is when i am clicking on a particular image in the gridview, it should shown as big image,how it is possible.
So this might be a fairly specific issue but I figured I'd post it since I spent hours struggling with it before I was able to determine the cause.
<asp:GridView ID="gvAttachments" DataKeyNames="UploadedID" AutoGenerateColumns="false" OnSelectedIndexChanged="gvAttachments_SelectedIndexChanged" runat="server"> <EmptyDataTemplate>There are no attachments associated to this email template.</EmptyDataTemplate> <Columns> <asp:TemplateField ItemStyle-Width="100%"> <ItemTemplate> <asp:LinkButton CommandName="Select" runat="server"><img src="/images/icons/trashcan.png" style="border: none;" /></asp:LinkButton> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView>
In the ItemTemplate of the TemplateField of the GridView I have a LinkButton with an image inside of it. Normally I do this when I have an image with some text next to it but this time, for whatever reason, I just have the image. This causes the UpdatePanel to always do a full postback.
I want to highlight a linkbutton on its click with a css and then remove its css when another linkbutton is clicked (ie) i want to show active link button.
How do I check which LinkButton is clicked in the Page_Load of the page. This is to avoid calls to service so that it only executes what is present in its event.
On the code behind, I am setting a variable called test and on Page_Load, changing the variable to something else. How come, when I click the dynamically added LinkButton, the test variable is not maintaining it's state:
i used a linkbutton inside repeater,when it is clicked whole page is refresh .linkbutton name is comment.i want when link button is clicked ,text box (txt comment) should be visible,without refreshing the entire page
