Hi
I am assigning the same ID to the check box which I am searching for using FindControl() method.
I'm doing everything the same as mentioned here: WEBSWAPP Development Inc.
except for creating the columns for the GridView in the Page_Load method. The columns for the GridView are being created just before data is bound to the GridView in a number of different places in the .aspx page

Hi

You could trace out the ID of every control in gvr:
foreach (Control ctrlChild in gvr.Controls)
{
Trace.Write("Child Item", ctrlControl.ID);
}
and see what .net thinks is there?

Hi guys,

It seems the server is not aware of the control being there at all.
I tried a different approach by adding a new cell with a check box control for each row in the RowCreated event, and it works beautifully.
Thanks guys.

hey guys,

I have implemented Repeater control in my web page. Working fine and information is displayed. The 30datas are displayed in this page. We dont have a paging properties in repeater control.

Can anyone help me how to implement a paging to Repeater control?

hi Oxy....

Try to implement it. I have given you the gest

The PagedDataSource class encapsulates the properties of the Repeater control
that allow it to perform paging.


PagedDataSource pagedDataSource = new PagedDataSource();
DataView userGroupMemberDataView = new DataView();
userGroupMemberDataView = loadMyGroup();



pagedDataSource.DataSource = userGroupMemberDataView;
pagedDataSource.AllowPaging = true;
pagedDataSource.PageSize = 24;

hi,


Try this code Oxygen, its worked for me...,


The PagedDataSource class encapsulates the properties of the DataGrid control that allow it to perform paging. But we can use the class with Repeater and DataList controls to perform paging in much the same way as a DataGrid.


Body of the page

<table width="100%" border="0">
<tr >
<td>&nbsp;&nbsp;<asp:label ID="lblCurrentPage" runat="server">
</asp:label></td>
</tr>
<tr >
<td>&nbsp;&nbsp;
<asp:HyperLink id="lnkPrev" runat="server"><< Prev</asp:HyperLink>
<asp:HyperLink id="lnkNext" runat="server">Next >></asp:HyperLink></td>
</tr>
</table><asp:repeater ID="Repeater1" runat="server">
<itemtemplate>
<table width="100%" border="0">
<tr >
<td>&nbsp;&nbsp; <%# DataBinder.Eval(Container.DataItem, "Product") %> </td>
</tr>
<tr >
<td>&nbsp;&nbsp; </td>
</tr>
</table>
</itemtemplate>
</asp:repeater>



<script language="C#" runat="server">
public void Page_Load(Object src,EventArgs e) {
DataSet ds;
//Instanciate Dataset
PagedDataSource objPds = new PagedDataSource();
objPds.DataSource = ds.Tables[0].DefaultView;
objPds.AllowPaging = true;
objPds.PageSize = 5;
int CurPage;
if (Request.QueryString["Page"] != null)
CurPage=Convert.ToInt32(Request.QueryString["Page"]);
else
CurPage=1;


objPds.CurrentPageIndex = CurPage-1;
lblCurrentPage.Text = "Page: " + CurPage.ToString();

if (!objPds.IsFirstPage)
lnkPrev.NavigateUrl=Request.CurrentExecutionFilePa th
+ "?Page=" + Convert.ToString(CurPage-1);

if (!objPds.IsLastPage)
lnkNext.NavigateUrl=Request.CurrentExecutionFilePa th
+ "?Page=" + Convert.ToString(CurPage+1);

Repeater1.DataSource=objPds;
Repeater1.DataBind();
}
< /script>

I have a GridView, I want the user to download an attachment . If there is an attachment related to that specific record. I have to download it.

Can anyone help me...

Given below is some of my code:

Private Sub projectGridView_RowCreated(ByVal sender As Object, ByVal e As GridViewRowEventArgs)

' Use the RowType property to determine whether the

' row being created is the header row.

If (e.Row.RowType = DataControlRowType.Header) Then
For i As Integer = 0 To e.Row.Cells.Count - 1

' Create the sorting image based on the sort direction.
Dim sortImage As Image = New Image

'Test whether or not session is exist

If Session(projectGridView.Columns(i).SortExpression) Is Nothing Or Session(projectGridView.Columns(i).SortExpression) = "ASC" Then

sortImage.ImageUrl = "../images/arrow_up.gif"

sortImage.AlternateText = "Ascending Order"

Else

sortImage.ImageUrl = "../images/arrow_down.gif"

sortImage.AlternateText = "Descending Order"

End If

' Add the image to the appropriate header cell.
e.Row.Cells(i).Controls.Add(New LiteralControl(" "))

e.Row.Cells(i).Controls.Add(sortImage)

Next

End If

If (e.Row.RowType = DataControlRowType.DataRow) Then
Dim attachmentImage As Image = New Image
attachmentImage.ImageUrl = "../images/paperclip.gif"
attachmentImage.AlternateText = "Attachment"
'Dim fileName As String
If projectGridView.Columns(0).HeaderText = "ID" Then
Dim connString As String
Dim con As SqlConnection


Try
connString = System.Web.Configuration.WebConfigurationManager.C onnectionStrings("ConnectionString1").ConnectionSt ring

con = New SqlConnection(connString)

Dim cmd As SqlCommand = New SqlCommand()
cmd.Connection = con

cmd.CommandText = "dbo.GetOpenProjectInfo"
cmd.CommandType = CommandType.StoredProcedure

Dim adapter As New SqlDataAdapter(cmd)

Dim proj As New DataSet
adapter.Fill(proj, "Projects")

'Response.Write(proj.Tables(0).Rows.Count & " ")
'Response.Write(proj.Tables(0).Columns.Count & " ")
If Not [String].IsNullOrEmpty(e.Row.Cells(0).ToString) Then
Dim i
Dim fileURL As String
Dim dr As DataRow
dr = proj.Tables(0).Rows(e.Row.RowIndex)
If [String].IsNullOrEmpty(dr.Item("FileName").ToString) = False Then
fileURL = Server.MapPath(".") & "\upload\" & dr("FileName").ToString
'Response.Write(" &nbsp;&nbsp;&nbsp;" & dr("FileName").ToString & " &nbsp;&nbsp;&nbsp;")
e.Row.Cells(0).Controls.Add(New LiteralControl("<a href=""" & fileURL & """>"))
e.Row.Cells(0).Controls.Add(attachmentImage)
e.Row.Cells(0).Controls.Add(New LiteralControl("</a>"))
End If
End If

'For i = 0 To ((proj.Tables(0).Rows.Count) - 1)

' Response.Write("<br />" & i & "<br />")
' Response.Write(dr.Item("FileName").ToString)

'Next i

'For Each dr As DataRow In proj.Tables(0).Rows
' If [String].IsNullOrEmpty(dr("FileName").ToString) = False Then
' Response.Write(dr("FileName").ToString & " &nbsp;&nbsp;&nbsp;")
' e.Row.Cells(0).Controls.Add(New LiteralControl(""))
' e.Row.Cells(0).Controls.Add(attachmentImage)
' End If
'Next dr

Try
con.Open()
cmd.ExecuteNonQuery()

Catch ex As Exception
Response.Write(ex)
Finally
con.Close()
con.Dispose()

End Try



Catch ex As ApplicationException
Response.Write("Could not load the database")
End Try
End If
End If

End Sub
Currently the items on RowIndex 1 and 2 have attachments. When the page loads, the attachments image shows up next the "ID" column in those rows.

hey,

The problem now is with the paging and sorting events. If I change the page or if I sort the Grid View, the attachment image stays on rows 2 and 3 and doesn't move with it's related "ID" row.

help out!

Hi:
When we want to pop up download box, we have to do something like this:
protected void Page_Load(object sender, EventArgs e)
{
Response.AppendHeader("content-disposition",
"attachment; filename=" + "1.bmp");
Response.ContentType = "Application/pdf";
//Get the physical path to the file.
string FilePath = MapPath("images/1.bmp");
//Write the file directly to the HTTP content output stream.
Response.WriteFile(FilePath);
Response.End();
}
Only thing is to pass query string to that page. You can sill use <a> then.
If your problem isn't solved, please inform me.
