Gridview header issue: call event on header
- by Joris
Now I got this gridview, And I need the headers to be clickable, whereafter an event starts (something like OnClickHeader="header_ClickEvent"?) Ofcourse there is a SortExpression element, which enables to sort the grid, but I want to be able to start any event, like when clicking a button.
I could not find any solution within the asp:BoundField nor asp:TemplateField...
I thought a hyperlink could solve the problem, but that was a bit premature.
Also, when using a TemplateField, I find it very hard to fill the column with data.
Could anyone bring me the solution?
The Gridview:
<asp:GridView CssClass="gridview" ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="Student_key" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" PagerSettings-Visible="false" PageSize="14">
<HeaderStyle CssClass="headerstyle" />
<RowStyle CssClass="rowstyle"/>
<AlternatingRowStyle CssClass="altrowstyle" />
<Columns>
<asp:BoundField DataField="Studentnumber" HeaderText="Studentnummer" >
<HeaderStyle CssClass="header100" />
</asp:BoundField>
<asp:BoundField DataField="Prefix" HeaderText="Voorletters" >
<HeaderStyle CssClass="header75" />
</asp:BoundField>
<asp:BoundField DataField="prename" HeaderText="Voornaam" SortExpression="Voornaam">
<HeaderStyle CssClass="header75" />
</asp:BoundField>
<asp:BoundField DataField="nickname" HeaderText="Roepnaam" >
<HeaderStyle CssClass="header100" />
</asp:BoundField>
<asp:BoundField DataField="insertion" HeaderText="Tussenvoegsel" >
<HeaderStyle CssClass="header100" />
</asp:BoundField>
<asp:BoundField DataField="surname" HeaderText="Achternaam">
<HeaderStyle CssClass="header100" />
</asp:BoundField>
<asp:CommandField SelectText="show results" ShowSelectButton="True" >
<HeaderStyle CssClass="header100" />
</asp:CommandField>
</Columns>
<EmptyDataTemplate >There are no results shown, please try again.</EmptyDataTemplate>
</asp:GridView>
