Let's say I have a ListView with DataPager like this:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="List.ascx.cs" Inherits="Lnow.Applications.CompanyManagement.Gui.Clients.List" %>
<asp:ListView runat="server" ID="itemsList" ItemPlaceholderID="item">
<LayoutTemplate>
<table class="simpleList">
<thead>
<tr>
<td>
<asp:Literal runat="server" Text="[Id]" meta:resourcekey="Id" />
</td>
<td>
<asp:Literal runat="server" Text="[Name]" meta:resourcekey="Name" />
</td>
</tr>
</thead>
<tfoot>
<tr>
<td colspan="2">
<asp:DataPager runat="server" ID="itemsPager" PagedControlID="itemsList" PageSize="5">
<Fields>
<asp:NumericPagerField />
</Fields>
</asp:DataPager>
</td>
</tr>
</tfoot>
<tbody>
<asp:PlaceHolder runat="server" ID="item" />
</tbody>
</table>
</LayoutTemplate>
<ItemTemplate>
<tr class="row">
<td>
<%# DataBinder.Eval(Container.DataItem, "Id") %>
</td>
<td>
<%# DataBinder.Eval(Container.DataItem, "Name") %>
</td>
</tr>
</ItemTemplate>
<AlternatingItemTemplate>
<tr class="row-alt">
<td>
<%# DataBinder.Eval(Container.DataItem, "Id") %>
</td>
<td>
<%# DataBinder.Eval(Container.DataItem, "Name") %>
</td>
</tr>
</AlternatingItemTemplate>
</asp:ListView>
Now I want to use DataPager to page search results. How do I do it?
I found two answers to this question, both have an issue I want to avoid:
1. Create method to support ListView's PagePropertiesChanging event.
2. Create method to support DataPager's PreRender event.
The issue, that I want to avoid is that both those methods require me to store collection of retrieved data somewhere. And I don't want to do it, cause I can't do it. Objects, that are bound don't have Serializable attribute, so I can't throw them into ViewState. Is there any other way to do this? Or do I have to create my own control for paging?
Don't forget to rate answer, that helped you. It will allow other people find their answers faster.

Hello, reviewing ASP.NET to handle printing of a worksheet.
Any suggestions as to what technology to use to handle it?
I had Crystal Reports in mind (have previous experience using it on Windows Forms) however in vs2010 and .net4 it seems to be in beta.
Any suggestions to handle this functionality? doesnt have to be a reporting tool.
Any help or tips are appreciated, thanks in advance!

Yes sure, we can use some code written in VB and some in C# in same Asp.net application. But they must be in different files.
For that, you need to have vb and c# files in different folder in App_code folder.and you need to make the entry in web.config in CODESUBDIRECTORIES tag.
For details, Have a look

Hi,
Thank you for your answers that worked fine
but there are a small problem
When you create a C# project and create App_Code and add in it for example cscode & vbcode Classes
you can call vb classes in cs classes but not the opposite, if you try to call cs classes in vb classes that not work.
Why?
i hope that not a problem 
another question: Can we apply it on windows form applications?? 
Thanks

Hi all,
I have one query like in business logic layer of catch block i want to create log file for handling the exceptions and in UI layer i want to redirect to error.aspx page . how to do that ?
Regards
Rama

Make your method return a value which you can use to determine wether the business logic code succeeded or not
public bool DoSomething()
{
bool result = false;
try
{
result = true;
}
catch
{
result = false;
}
return result;
}
and then on your asp page check wether the function failed or not
if (DoSomething())
{
}
else
{
Respone.Redirect("Error.aspx");
}

Hi,
I want to populate Month like Nov-2010,Dec-2010 etc.. in DropDownList. It will show current financial year and so on....
Can any one help me regarding this.
Thanks...
|
|
|
|

I dont know, Might be some third party control can provide you month in this format. You your self can create the month like this and bind it to the dwopdown,
Or you can hardcode it in a file and bind it from there when require.
|

|
|
|
Thanks for reply. But, I don't want to hardcodeit. I simply want to read system date.
|
|
|
|
|
TRy like this in Database
select convert(varchar(3),datename(mm,getdate()),24) + '--' + convert(varchar(4),datename(yy,getdate()),24)

Hi,
I have a gridview with Edit And Delete buttons.
Here is one of the columns:
<asp:TemplateField HeaderText="החל מ-">
<EditItemTemplate>
<asp:TextBox ID="txtStart" Width="150px" ReadOnly="true" BackColor="LightSteelBlue" runat="server" Text='<%# Bind("startHour") %>'></asp:TextBox></EditItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtStartNew" Width="150px" runat="server"></asp:TextBox></FooterTemplate>
<ItemTemplate>
<asp:Label ID="lblMStart" Width="150px" runat="server" Text='<%# Bind("startHour") %>'></asp:Label></ItemTemplate>
</asp:TemplateField>
I've set the TextBox in the EditItemTemplate to ReadOnly.
My Problem is-
that i want to change the property (ReadOnly) to False after i pressed on the Edit button if some cell has a value.
I've tried to do this in the RowEditing event -
TextBox txtStart = (TextBox)GridViewIpTab.Rows[e.RowIndex].FindControl("txtStart");
but i got "Object reference not set to an instance of an object".
Can some one please help me with this problem?

Have you debugged it?
I would more than likely handle this on the client-side with some JavaScript.

You might try doing this in RowDataBound event:
if (e.Row.RowType == DataControlRowType.DataRow)
{
if (GridViewIpTab.EditIndex == e.Row.RowIndex)
{
TextBox txtStart = (TextBox)GridViewIpTab.Rows[e.Row.RowIndex].FindControl("txtStart");
}
}
In RowEditing do:
GridViewIpTab.EditIndex = e.NewEditIndex;
BindYourGrid();

Code, follow, or get out of the way.

You can reference this example:
protected void gv4PPdata_RowDataBound(object sender, GridViewRowEventArgs e)
{
if((e.Row.RowState & DataControlRowState.Edit) > 0)
{
TextBox curText;
for (int i = 1; i <= 6; i++)
{
curText = (TextBox)e.Row.Cells[i].Controls[0];
curText.Width = Unit.Pixel(60);
if (i == 1)
{
curText.Enabled = false;
}
}
}
}

Hi.
I'm creating a web app with ajax.
I added tab control(from jquery ui) that enables to add tabs dynamically.
So if the user wants for example to add a new customer he will open a new tab with the "add customer form".
Now, if i open a couple of this tabs i have a problem with conflicting id's because each tab that opens receives from the server a chunk of ready html that contains a form with controls that some of them have a id's.
My question is , what are the main techniques to add lots of html to a single aspx page that avoids confilicting id's and etc.
Thanks.
