I have an SqlDataSource object, linked to a GridView, which receives data from a database when executed.I'd like to add the values of the "Cost" column, to get the "TotalCost", and place it in a TextBox or Label on top of the GridView.Is it possible to just use (recycle) the data in the SqlDataSource object, instead of using another SqlDataSource object to just get the TotalCost"?
View 1 RepliesI have a asp.net page that has several SqlDataSources defined that feed data into some graphs. The problem is that the graph product does not handle "no data" very well, and throws an error. I'd like this to handle the situation more gracefully-- so I need to check whether the SqlDataSource returned data or now before rendering the graph (and if not, just post a message saying "No Data" or something).
Is there an easy way to check if the data source returned data, and do this if/then without a bunch of code behind?
I have a SqlDataSource and a GridView.
What I want to do is, while the query is executed (i.e. for inserting a data), then after the data has inserted successfully, it should appear a message sounds: "The data deleted successfully". I've solved it by using GridView1_RowDeleted method.
Now the problem is, I want to catch the error while the query is failed to executed. If the query has failed to execute, then it should appear a message: "The data failed to insert."
I have a basic page which has fields that I read from the database and write to it. I would like to know where I should call the insert and read commands. I know about age_load but heard about page_loadcomplete.I noted that when the user refreshes the page, for some reason the sqldatasource loads the old data(before the write) even though new data has been loaded on the form.

View 1 RepliesI am writing a clean up program to use in my computer repair business. I have been searching this site as well as Google to find an answer for how to get the size of the recycle bin.

View 4 RepliesI'm trying to set the format of a column in a datagridview.When I put the format statement in the on load event for the form, it has no effect. When I put it in the cellformatting event I get the "Object reference not set to an instance of an object" error. I checked the column name. What I am doing wrong?
This is the code:Private Sub MeetingTblDataGridView_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles MeetingTblDataGridView.CellFormatting
Me.MeetingTblDataGridView.Columns("Starttime").DefaultCellStyle.Format = "HH:mm:ss"

I am writing a program to manage some of my files. I already know when I want to send a file to the recycle bin, so I don't need the system to prompt me each time. How do I tell it to back Off, and just do it?
Here is my

My.Computer.FileSystem.DeleteFile(strFilename, FileIO.UIOption.AllDialogs, FileIO.RecycleOption.SendToRecycleBin, FileIO.UICancelOption.DoNothing)

Some of my research has pointed me to FileIO.UIOption.AllDialogs.
Right now this can only delete one file, how can I change it so that it can Empty the TEMP folders contents into the recycle bin?

How do you move multiple files to the recycle bin all at once? I want the recycle dialog box to show that says "Are you sure you want to send X items to the Recycle Bin" I have tried the API functions with SHFileOperation and have tried the My.Computer.FileSystem.DeleteFile but i can only delete one file at a time. I do not want to delete an entire directory but rather just a selection of files that i specify just like what can happen in windows explorer.

I want to call a Stored Procedure using SqlDataSource. I've been reading the library documentation of the classes but i'm getting slightly confused. To call a stored procedure, I understand that I have to change the selectcommandtype and then set the selectcommand property to the name of the procedure.

I'm making a cleaning program and one of the things it does is cleans the recycle bin. How do I do it for Xp, Vista, and 7? I'm on Visual Basic 2010. Also, how do I make it so that it automatically finds the username and uses it when the program deletes a folder. Right now I have it so that you need to enter your username in a textbox and then it uses that for the directories. I know it's something with SystemInformation.UserName.
