Are you going through your spec one step at a time and asking us to write your code for you ?

Hi,
I am using an objectdatasource with gridview. I have enabled paging for my datasource and gridview. It works great but there is one problem. On same page, i also have brands dropdownlistbox so one can chose between different kinds of laptops. The first item is "All". All selects quite a number of rows and there can be upto 20 pages. For dell laptops, i have only 2 models in table. What happens is that if a person navigates to page 10 in All devices and then changes the dropdown to Dell, there are no records in the grid. I have debugged and it happens because startrowindex is not 0. I am using mysql and have used limit. If a person is on page 1, one can see the 2 dell models.
How would i be able to solve this problem?. Sorry if its a stupid question, Is there anyway in which i can change the startrowindex to 0 in DropDownlistbox change index event?
Thankyou in advance.

When binding the grid view after changing drop down list, try setting the PageIndex property of GridView to 0.

Please, I want to know how to create warning yes/no message boxes using C# and ASP.NET. For example, Are you sure you want to delete this?
|
|
|
|
|
Use the JavaScript method; confirm
if(confirm('Are you sure you want to delete this?'))<br />

Thanks Mark.
But please, explain to me how to use the confirm method. When I used it an error is displayed on compilation "The name confirm dosen't exist in the current context"?? Do I have to provide code for this method before calling it?
|

You use it as I've given within a JavaScript block on your page, nothing more. Perhaps you could show a sample that is giving you problems, or search this site or others for examples.

Hi Mark,
The problem is that I'm using C# to write my code. On confirming the delete message, my program should delete all information related to a student. So I create a new SQLDataSource and then write the delete command as follows.
SQLDataSource DeleteStudentInfo = new SQLDataSource();
DeleteStudentInfo.DeleteCommand = "Delete From Student Where StudentID = @StudentID";
Then I identify my delete parameters.
How to insert javascript code before my C# code shown above?
Thanks Mark

You don't. JavaScript is run on the client, C# code is run on the server. I think you should reread a couple chapters in the book or ask the professor or TA for help, your missing some concepts.

Honstly, I don't know anything about javascript, only heard about it.
But you don't have any suggestions for me? Actually I don't know where to insert the code you have given me?
Do you know a professor or TA that I can ask? Also, Do you have a good book that I can work with it easily?
Thanks very much for help and sorry for any inconvenience I'm causing.
