In the page, you build it like a regular webpage with the header and footer, and in the middle, you place a content placeholder object, a container that will hold that space in the seperate file you created.
default.aspx - reference the container in the master page in your content page, and content below will be injected into the master page.
<asp:ContentID="Content3"ContentPlaceHolderID="SiteMap"runat="server"><!-- Encode the Sitemap Content of the Page --><divclass="sitemap_container">
Some content such as words or pictures in your seperate file
I am looking to incorporate the Excel Like Grouping on the columns of my grid view, Can this be done using the standard .net functionalities, if not can anyone recommend a 3rd party component library with features like this.
this is my error
i change textbox at gridview to dropdownlist (tempaltefield)
string connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=DB.mdb";
OleDbConnection con = new OleDbConnection(connString);
OleDbCommand cmd = new OleDbCommand();
cmd.CommandText = "UPDATE Pay SET pay_sup_name=@pay_sup_name,pay_value=@pay_value,pay_check_No=@pay_check_No WHERE pay_id=@pay_id";
Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.TextBox
Error in itself is quite straight forward.
You are directly casting controls from Grid cells into a defined type. One of the conversion is not correct. There is a Literal control instead of a textbox. A simple use of Visual Studio debugger will tell the line of code. Once you know, just handle it properly.
