Adding button in asp:repeater

S

simon

I have <asp:repeater> with Item template:

<ItemTemplate>
<%# writeLine(DataBinder.Eval(Container.DataItem, "danIme"),DataBinder.Eval(Container.DataItem, "timeStart"))%>
</ItemTemplate>

In my function writeLine, I would like to add in some cases, <asp:button>
Protected Function writeLine(ByVal dayName As String, ByVal timeS As String) As String

If dayName="Friday" then
writeLine="<asp:button> + some HTML sintaks"
else
writeLine = "some html sintaks"
end if

End Function


How can I do that?

Thank you,
Simon

Can I have some if statements in my template, like I have them into my write functions.

For example:
<itemTemplate>
<%IF danIme=dayOld then%>
<tr><td><asp:button>
<% else%>
<table><tR>.......
<%end if%>

Simon,

On databinding stage you can't add any server controls programmatically. You rather should include everything in the template and manipulate visibility settings.

Why I can't use in my function writeLine, which is in my ItemTemplate, some other control clientID property?

Is there some other way?

writeLine = "</td></tr><tr><td><table bgcolor='white' width=100%><tr><td>" & dan & "</tD><td><input onclick='" & btnDelete.ClientID & ".click()' type='button' value='Delete'></td></tR><tr><td><ul>"

No. The point is that server components need compilation and it happens before databinding. Put all server controls in the template and than set Visible=false in the code-behind or databind Visible property in the ..aspx file. A server control with Visible=false won't be rendered to the client, exactly what you want if I understand you correctly.

If I have:
<ItemTemplate>
<tr runat="server" id="trName">
<td><%#DataBinder.Eval(Container.DataItem, "danIme")%></td>
</tr>
<%# writeLine(DataBinder.Eval(Container.DataItem, "danIme"),DataBinder.Eval(Container.DataItem, "timeStart"))%>
</ItemTemplate>

AND then in writeLine function I would like to set the visible property of my row:
trName.Visible = False

I get an error message: Not set to the instance of the object.

In page I have declared:
Protected WithEvents trName As System.Web.UI.HtmlControls.HtmlTableRow

Where is the problem and how I can solve it?

Simon,

Are you sure you are on the right track? What us your task? Looks, like you are trying to build a table in a repeater? What does writeLine do? Trying to write an html for the table row?

May be you should rather re-design to using normal datagrid with templates built in a regular way?

Eliyahu

If I have:
<ItemTemplate>
<tr runat="server" id="trName">
<td><%#DataBinder.Eval(Container.DataItem, "danIme")%></td>
</tr>
<%# writeLine(DataBinder.Eval(Container.DataItem, "danIme"),DataBinder.Eval(Container.DataItem, "timeStart"))%>
</ItemTemplate>
