I have Change your code please,

'Bind GridView Method
Public Sub BindGridView()

Dim oDS As New DataSet

strSql = "Your Query"

oDS = db.ExecuteDataSet(strSql)
DG_CheckBox.DataSource = oDS
DG_CheckBox.DataBind()

End Sub

'Return Dataset
Public Function ExecuteDataSet(ByVal strsql As String) As DataSet
Dim dtad As SqlDataAdapter
Dim dtst As DataSet
dtst = New DataSet
dtad = New SqlDataAdapter(strsql, GetConnection)
' GetConnection Get the sql connection
dtad.Fill(dtst)
CloseConnection()
Return dtst
End Function

Protected Sub DG_CheckBox_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles DG_CheckBox.PageIndexChanging
Try
DG_CheckBox.PageIndex = e.NewPageIndex()
BindGridView()
Catch ex As Exception

End Try
End Sub

U Can use EmptyDataText if your query doesnt returns any records.
eg: EmptyDataText = "No Record Found"
Else u can use your code also for showing error "No Record Found"

Hope this helps u...

Hi,

I am looking for a rental system like for videos or property, it must be open source. Does any one know of something like this?? It must preferably have a back office and must be integrated into a payment gateway, like Pay Pal for example. But the payment gateway is not required, I'm also looking for a rental calendar, where a user can look at what dates a property has been booked for.

Please can someone help me out.

you can add item at run time

<br />
 DropDownList1.Items.Add(new ListItem("text","Value"));<br />

I think you can't do it using drop down list .
You can go with different approach by Adding one more TextBox
When user selects item from drop down list it will get into text where you can Edit it and After editing Add back to drop down list ...

COM componenets are very usefull if you want to use other OS applications in your own projects such as Excel,Winword , Internate Browser etc

vijay_83 wrote:

Yes Actually DOT NET interanally uses COM+ technology COM is used to communicate with different languages.
Also COM has a major role in MSIDL Microsoft Interface defination Language

No thats not true Using COM objects makes application bulky causing high memory usage.

Asp.Net Ajax 1.0 was previously called Atlas. They are mostly the same, but as development went along some things were changed so the former is not compatible with the latter.

Could nay one tell me or give me clear idea about the difference between Abstract and virtual keyword.i searched google but i cuoldnt get satisfiable solution.this was an interview question
thanks in advance

Virtual keyword is used to declare methods which allow derived classes to override the implementation, as some default implementation is already specified in the base class method. Where as abstract keyword is used to declare methods with empty body and derived classes have to write the implementation. This is the basic difference.

Prakash Kalakoti

Re: Interview Question

Sandeep Akhare9-May-07 0:38

Sandeep Akhare

Virtual Keyword :

<br />
The virtual keyword is used to modify a method, property, indexer or event declaration, and allow it to be overridden in a derived class. <br />
When a virtual method is invoked, the run-time type of the object is checked for an overriding member. The overriding member in the most derived class is called, which might be the original member, if no derived class has overridden the member.<br />
<br />
<br />

Abstaract Keyword

<br />
The abstract modifier can be used with classes, methods, properties, indexers, and events. Use the abstract modifier in a class declaration to indicate that a class is intended only to be a base class of other classes. Members marked as abstract, or included in an abstract class, must be implemented by classes that derive from the abstract class.<br />

Virtual properties behave like abstract methods, except for the differences in declaration and invocation syntax

Maintaining viewstate of a grid.

Hi,

How to maintain the viewstate of a datagrid which is updated using javascript.
If i do a postback then the updated values are not maintained.

Can anyone tell me how to do it.

Regards,
Riz

Unless there is a component out there for Javascript to be able to update the viewstate then you will have to find another way to alert the server that changes have been made. You can probably include a hidden field that the javascript can change at the same time as the grid. The Server will then pick up the value of the hidden field which you can then act on.

Hi,

I am using a listbox in the grid so there can be many records in the listbox in each row of the grid.I am updating the entire grid with all the values in the list boxes in the end.The values in the listboxes for each row in the grid can be different. It is not possible to use a hidden field here so there can be any number of records in the listboxes.
Do u have any other alternative?
