<asp:ButtonColumn Text="Resend" ButtonType="PushButton" CommandName="Resend"></asp:ButtonColumn> </Columns>
But I don't know where to access the event of this Button, also I would like to know how to retrive the row data of this button .
I have a table with two columns (id and number1). How can i get from the datagrid or the dataset the data of one column (number1) in one variable?
View 7 RepliesI have a datagrid and set of collection of columns for the datagrid. I have added cloumnname and headertext using column collections in design time. I have made false of autogenerated column. I was unable to load the data in datagrid from datatable. If i remove the collection and add bind data in datagrid means working fine but not for the column collections.VB.net windows application.

View 14 RepliesFinally got to the point of having a work webservice using php and nusoap. I can retrieve values and send. Now what I want to do retrieve multiple values into a data grid, I think. What I want to do is retrieve various messages specific to that user. At the moment I retrieve values individually but as there may be more than one result I assume the datagrid may be the way forward. Now the question is how can I retrieve this information. Currently my data returns in the following format.
name.Text = returnData.name
I have encountered a problem where in my database I have a column that is a bit either 0 or 1 specifying if a user is an admin or is account suspended or not. And in my VB code I am trying to retrieve that bit. Example code:
Dim dtRequests As DataTable
dtRequests = New DataTable("Users")
dtRequests.Columns.Add("SESLoginID", System.Type.GetType("System.Int32"))

I tried getting rdr.GetByte(3), this tells me cast not valid, but there is no function of which will say GetBit, and if such exists I could not find it.
It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

View 2 RepliesI'm making a timer program, that I want to be able to store "unlimited" timer profiles, that someone can load and use. Now I've created a form that you fill with data, which then gets saved to a .xml file in a pre-defined directory. I'm now working on some sort of code that will:
1. Search the directory for .xml files
2. Find any .xml files and convert names to strings
3. Store the strings in a dropdown menu, so that when one is chosen, it loads that profile.
I think I have 1 down:
System.IO.Directory.GetFiles("C:Simple Timer")
Dim di As DirectoryInfo
di = New DirectoryInfo("C:Simple Timer")
di.GetFiles("*.xml")
