I also face this problem earlier. My solution was first I save the file from the network drive to our local machine through our code and then upload it from the local machine.

Thanks

ok. apologize.

here's the new question::

How can I make asp dropdownlist treat like combobox just the same in access?
In access, combobox is behaving like textbox meaning
you can input directly whatever you want.

You can use Ajax control toolkit for the same.
Please take a look over here: http://www.asp.net/ajax/ajaxcontroltoolkit/Samples/ComboBox/ComboBox.aspx[^]

Hope this will help you.

You should use AutoComplete extender control for this purpose.
Use this extender for a TextBox instead of a DropDownList. Populate the autocomplete data from the database.

Please have a look at the demo here[^].

Checkbox inside gridview.

Hi,
I have a checkbox inside a gridview which is bound to data at runtime except the checkbox templatefield.

At server side I am trying to capture the row details for the row which is selected. I get the checkbox but the checkbox.checked is always false even when it is selected.

protected void btnSelect_Click(object sender, EventArgs e)
    {
        foreach (GridViewRow row in GridView1.Rows)         
        {             
           
            CheckBox chk = (CheckBox)row.FindControl("chkAgency");
                       
            
            if (chk != null && chk.Checked)             
            {
                Response.Cookies["thistestcookie"].Value = row.Cells[0].Text.ToString();
             }         
        }

how do i get the checked checkbox row details ?!

Thanks,
Fifi

ok i see where your problem is. You assume if you add a checkbox, it will carry the ID of the checked field , that is not true. I normally create an extra template field and bind the label with the value and as you did on the server side, i find the label and get the value. I have compiled an example and this will help you

html

    <asp:GridView ID="GridView1" AutoGenerateColumns="False" runat="server" 
        DataSourceID="SqlDataSource1">
        <Columns>
            <asp:TemplateField>
            <ItemTemplate>
            <asp:CheckBox ID="chkAgency" runat="server" />
            </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField>
            <ItemTemplate>                     
            
            <asp:Label ID="lblid" runat="server" Text='<%# Eval("ID")%>'></asp:Label>
            </ItemTemplate>
            </asp:TemplateField>
            <asp:BoundField DataField = "ID" HeaderText = "ID" InsertVisible="False" 
                ReadOnly="True" SortExpression="ID" />
            <asp:BoundField DataField ="Descr" HeaderText = "Descr" SortExpression="Descr"/>
            <asp:BoundField DataField = "LongName" HeaderText = "LongName" 
                SortExpression="LongName"/>
            <asp:BoundField DataField="Capacity" HeaderText="Capacity" 
                SortExpression="Capacity" />
            <asp:BoundField DataField="Note" HeaderText="Note" SortExpression="Note" />
     </Columns>
    </asp:GridView>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
        ConnectionString="<%$ ConnectionStrings:TTBLv3MasterConnectionString %>" 
        SelectCommand="select * from dbo.TBL_VENUE"></asp:SqlDataSource>
<asp:Button ID="btntest" Text="Test" runat="server" onclick="btntest_Click" />

and the server side

protected void btntest_Click(object sender, EventArgs e)
   {
       foreach (GridViewRow row in GridView1.Rows)
       {

           CheckBox chk = (CheckBox)row.FindControl("chkAgency");


           Label lblid = (Label)row.FindControl("lblid");

           List<string> lstList = new List<string>();

           if (chk != null && chk.Checked)
           {
               //Response.Cookies["thistestcookie"].Value = row.Cells[0].Text.ToString();
               lstList.Add(lblid.Text);
           }
       }
   }

Thanks

I create a gridview with runtime columns. after that add textbox in this column.
Here the code.
protected void grdOne_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
TemplateField T = new TemplateField();
grdOne.Columns.Add(T);
GridViewRow gvr = e.Row;
TableCell tcell = new TableCell();
for (Int32 i = 0; i < columnCounter; i++)
{
TextBox tb = new TextBox();
tb.Width = 30; tb.Text = "0";
tb.ID = "tb_" + i.ToString();
tcell.Controls.Add(tb);
}
gvr.Cells.Add(tcell);
grdOne.Controls[0].Controls.AddAt(0, gvr);

}

}

But when i fetch textbox value from this grid that comes with error.
can any one tell me how to fetch textbox value from my grid
m using these line of code to fetch textbox values

public void GetArray(GridView grd)
{
String[,] ar = new String[rowCounter, columnCounter];
for (int i = 0; i < grd.Rows.Count; i++)
{
for( int j=1; j<= grd.Columns.Count; j++)
{
String tId = "grdOne_ctl03_tb_" + j.ToString();
String t = ((DataControlFieldCell)(grd.Rows[i].FindControl()).text;
}

}
}

Something issue with control Id, it's not able to find the exact control id. It may be issue with control hierarchy. I have some suggestion for you:
1. If you want to follow the same code then view the page source and see what is name of control id and under which parent control has created.

2. Other way, Create a template column at design time and put there a panel. On runtime find the panel and add the all textbox control inside the panel.
same way, during retrieval find the Panel and traverse the all child control.

Hi!
I don't know how you keep session in app_code folder. Anyways Create the static class for session under the app_code folder and use it where you want.
Class should be like that..

public static class SessionManager
{
private static string _Id= "DefaultID";
public static string ID
{
get
{
if (HttpContext.Current.Session[SessionManager._Id] == null)
{
return string.Empty;
}
else
{
return HttpContext.Current.Session[SessionManager._Id].ToString();
}
}
set
{
HttpContext.Current.Session[SessionManager._Id] = value;
}
}

}
///////////////////////////////
and use like that
SessionManager.ID="testId1213"; //set

string idValue =SessionManager.ID; //get

in a Class Library or in a Class you cant just access the Session Variable like that, so you will need to do it like this

HttpContext.Current.Session["MySession"].ToString();

The feature that you are looking for is provided by Forms Authentication[^]. There are lots of information on web[^] regarding the same.

OR

You can do this yourself. Keep a session flag in your application. Set it to true/logged-in, once someone logins. Orelse keep it as false/not-logged-in. On any other page load, check the value of this session and move accordingly. If you find its value as false then do a hard Response.Redirect yourself in the code to login page.

Look at this

http://www.dotnetfunda.com/articles/article808-how-to-write-a-simple-login-page-in-aspnet-.aspx[^]

Now to extend this , you will need a Session variable that will carry the username of the Successful login and every page you must check if the Session is null , if its null redirect the user to the Login Page like this

if(Session["Usernane"] == null)
{
response.redirect("Login.aspx",false);
}

and when you are done with the session, meaning when the user logs out then you must abandon the session. or set it to null

I want to keep the Data access layer in a different class library project, but how can I manage Web.Config file ?

Hi,

I want to encapsulate the Data Access Layer in a class library project where the class library will contain LINQ to SQL classes and Business Logic Layer. For my ASP.NET Web application, I will add that class library reference so that the ASP.NET Web application just behave like the Presentation Layer. I am highly tempted to implement this architecture. But I just got one challenge. As the Data Access Layer will maintain the Connection String of the SQL database in Web.Config file, when I reference that class library DLL to my ASP.NET Web Application, how will the Web.Config file of that class library project get integrated to my web.config file of the presentation ASP.NET Web Application ?

At this moment, I am using ASP.NET 4.0 which has a cool feature : Web.Config.Debug, Web.Config.Release, so I can place the connection string of my production server website at Web.Config.Release. But, now, looks like, I will have to miss that feature as I am not sure how Web.Config (or App.Config) file will behave in my Data Access Layer class library project.

Would you please give me some idea ?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
