Foor loop Code Block in ASPX Page

Ma tju

Hi guys, I got little problem here. I cannot get the value for ColName. Below are my code

<tr ondblclick="job_detail('<%#Eval("id")%>');" >
<td width="15"><input name="Checkbox51" type="checkbox" style=" width:13px; height:13px;" value="<%#Eval("id")%>" /></td>
<%
For j = 0 To countCol - 1
Response.Write("<td width=" & colSize(j) & ">" & Eval(colName(j)) & "</td>")
Next
%>
</tr>

It give me an error : Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. Can someone help me. Thanks in advance. matju

Hi, Actually i need to use Eval to bind the data from datasource. But to use eval I need to include the '#' sign.

Sure, here is the code.

    Dim conn As New         SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings(0).ConnectionString)
    Dim sqlDA As New SqlDataAdapter("SELECT id, filename, img\_size FROM image ORDER BY id", conn)
    Dim ds As New DataSet
    Dim pgDataSrc As New PagedDataSource
    Try
        sqlDA.Fill(ds, "tl")

        pgDataSrc.DataSource = ds.Tables("tl").DefaultView
        pgDataSrc.AllowPaging = True
        pgDataSrc.PageSize = 20
        pgDataSrc.CurrentPageIndex = CurrentPage

        'rptInbox is a repeater control
        rptInbox.DataSource = pgDataSrc
        rptInbox.DataBind()

    Catch ex As Exception
        Return False
    Finally
        conn = Nothing
        sqlDA = Nothing
        ds = Nothing
    End Try

Well sometimes user want to see just 1 or more column in the repeater. Thats why i use for loop to generate the column. Hope this help. Thanks in advance.

why should you write the response.write here as bind function only work with control. you can use just Databinder.Eval() or simply Eval() as it your repeater control you get all the values. for more specify your exact need to writing the response.write as its just give the message.

Actually I try to do this:

<%
For j = 0 To countCol - 1
'during loop it will skip this line. This is why I use response.write.
<td width=<%#(colSize(j))%>><%#Eval(colName(j))%></td>
Next
%>

but when it loops it will skip the code in the for loop. When i use response.write it will run line in for loop but return this error: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. Hope this help. Thanks in advanced.

why you put the for loop as it is in the repeater. repeater will automatically manage this. it will returns for all the rows. can you more specify your exact requirement as what type of data you want to bind here?
