Question

I currently have a Gridview that displays

TypeID , Name , Description.

I would like to display the actual type name instead of the TypeID in the gridview. I created this function that takes in the ID and returns the Name but I am having trouble using it. There are 15-20 different types so How do I convert the TypeID to a Type Name so that it is displayed when the Gridview is rendered.

protected string GetGenericTypeByID(int genericTypeID)         {             string genericTypeName;              GenericType.Generic_TypeDataTable genericTypeNameDS = new GenericType.Generic_TypeDataTable();             genericTypeNameDS = GenericBO.Get_GenericTypeByID(genericTypeID);              genericTypeName = genericTypeNameDS[0]['Generic_Type_Name'].ToString();                      return genericTypeName;          } 

I thought I would be able to use the function in the ItemTemplate but it seems to be harder that I thought

 <ItemTemplate>                     <asp:Label ID='Label1' runat='server' Text='<%# Bind('GetGenericTypeByID('Generic_Type_ID')')%>'></asp:Label>                 </ItemTemplate> 

Thanks to Everyone who helped me solve this problem. I ended up using the method below and it works perfectly. GetGenericTypeByID( Convert.ToInt32(Eval(‘Generic_Type_ID’)))

You’ve got the ‘bind/eval’ and method call inside out.
See Using Method inside a DataGrid or GridView TemplateField

<asp:TemplateField HeaderText=”Name”> <ItemTemplate>     <a href='<%# FormatUrl(Eval(”email1″).ToString())%>'><%# Eval(”fname”) %>,&nbsp;<%# Eval(”lname”) %></a> </ItemTemplate> 

With the ‘FormatUrl’ function being:

public string FormatUrl(string email) {     return “mailto:” + email; }
