Hi,

I want to change the control dynamically in the grid. In my grid there are two columns. By default 1st column displays label with some text. In second column will be having a check box. If I select the check box, I need to change the label to textbox and I want to edit in 1st column. How to do it in C#.net. It's urgent. Please help.

Thanks in advance,
Reddy.

In RowCreated event
1. Goto the column where you want to add the new control.
2. Find the label control and remove it from ControlCollection.
3. Create a textBox and add it to the column's ControlCollection

Hi,

ComponentOne's Chart for .NET allows you to draw various 2D and 3D charts. The following link http://www.componentone.com/products.aspx?ItemType=1&TabTypeID=1&PanelIndex=12&TabMapID=120&Itemid=21&Tabid=146&SubCategoryTypeID=3[^] shows some of the possible 2D chart types. You can also create Gantt charts, but they are not pictured on that page. To see some of the possible 3D charts, please visit this link http://www.componentone.com/products.aspx?ItemType=1&TabTypeID=1&PanelIndex=12&TabMapID=121&Itemid=21&Tabid=148&SubCategoryTypeID=4[^]. If you install the evaluation, there will be many samples to show you how to work with the Chart control.

From what i understand in your question is that you will implement exit(0) function in an asp.net web page...From my point of view is that there is no equivalent of exit(0) in an asp.net webpage since the browser is not an application of the asp.net..if you want to exit in an asp.net page use the response.redirect or if you want to close the browser you can use the javascript window.close().

You got multiple threads? Make sure they marked as background threads otherwise they'll keep your app alive.

hi,
i have a certain internet based program running on this computer, and i'd like to check it's network i/o.
i've tried to do it with basic tcplistener/tcpclients like i used to do with web programming, but apperently when its a program and not a webpage, the port is declared as 'used' and i cant listen to it.
i know there is probably some easy way to do it and i sound pretty much like a 1-day-user, but i truely have no experience with actual 'exe-programming'.
all im basicly looking for is a code to list all i/o from the selected port, and write it to console screen or whatever available.

thanks for any help.

gridview select error

Hi all!!

I have the following gridview error, and I am not sure how to fix it.

I have the following object datasource:

<asp:ObjectDataSource id="odsOrders" TypeName="MyName.BusinessLogicLayer.Order" runat="server">
</asp:ObjectDataSource>

And here is my gridview (part of it):

<asp:GridView id="gdvWineries" DataSourceID="odsOrders" DataKeyNames="ID" AutoGenerateColumns="False"
AllowPaging="true" PageSize="10" Width="100%" runat="server">

<Columns>

All my coloumns here.

</Columns>

</asp:GridView>

I have the select statement in my Page_Load event handler because the select statement can use onr of 2 methods to populate the gridview, depending on the roles of the user.

if (!Page.IsPostBack)
{
if (Role.IsInRoles("SystemAdmin"))
{
odsOrders.SelectMethod = "GetAllOrders";
}
else if (Role.IsInRoles("WineryAdmin"))
{
odsWineries.SelectParameters.Add(new Parameter("strMemberUsername", TypeCode.String,
User.Identity.Name));
odsWineries.SelectMethod = "GetWineryByMemberID";
}
}

Then at the bottom of the gridview it displays 1 2 3 4.. for the page numbers, but when I click on one of these numbers I get the following error:

The Select operation is not supported by ObjectDataSource 'odsOrders' unless the SelectMethod is specified.

Can someone please help me why I get this error and how to fix it?

Regards,
ma se
