Pass GridView Cell Value To Sub Routine In ASP.NET?
Feb 15, 2011
I have a GridView with Cell 0 containing the ID that I need to pass to a Public Sub.
I cannot figure out how to pick the value from Cell 0 in order to pass it to the Sub. I have tried experimenting (see the Dimmed EventID below) but have failed. Here is my code:
Protected Sub gvAppointmentsCalls_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvAppointmentsCalls.RowCommand

Isn't there a way in VB to pass an array literal? Say the subroutine ask for an array of integers and you have just one. Can't you do something like
DoSomething({MyNum})
instead of
Dim MyNums as Integer() = {MyNum}
DoSomeThing(MyNums)
I'm thinking I'm just missing some adornment to the array literal inorder pass it.

Is it considered bad practice (VB.NET or any language) to code a function with both ByVal and ByRef parameters as used in my getFile function below?
Function getFile(ByVal channel As Integer, _
ByRef Filename As String, _
ByRef Filesize As String) As Integer
End Function
Dim status As Integer

I am using sockets to send message between computers. I send the messages alright. What I want is when the message "x0x" comes, the client must be closed within 5 minutes. Teh admin can cancel the request by sending message "-xx" as well. The routine that checks for incoming connections and accepts messages uses WHILE TRUE...END WHILE since it must always listen. Once I get a message, I need to fire a timer control or other that fires within 5 minutes. But the program cant leave the WHILE TRUE at all. If i exit it early, the timer fires and the program does get exit. How do I fire the timer or other routine while still the WHILE TRUE routine checks for incomin connections and messages?

is there any way to reference a particular code routine in VB.net external to the current loop/routine?Example:
If Var01 < 5
[Routine A]
Else
[Routine B]
End If
where Routine A and Routine B are code sequences at the end of the entire program -- such as outside of the current sub or class? The idea would be to reference an otherwise repetitive code.

I know this will be easy, but I can't seem to find it anywhere. How do you SET the current row in a gridview? I find tons of ways to get data from it, but I what to set a current row or cell programatically. I'm using VB 2008 express. I also find lots of promising properties like Selected... but these are all read only and i can't set them.

I have a gridview and use a session to pass the variables from the page to an edit page. This works perfectly, until you search for a number. When you search the correct record displays in gridview, but when you click edit, it passes the wrong record.
Private Sub gridview1_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridView1.RowEditing
Session("wr_id") = GridView1.Rows(e.NewEditIndex).Cells(2).Text & "~/~" & _
GridView1.Rows(e.NewEditIndex).Cells(3).Text & "~/~" & _
GridView1.Rows(e.NewEditIndex).Cells(4).Text & "~/~" & _
[Code] .....
I realize not all of the code is pasted in here, because it would take too much space. Any Ideas? I'm guessing it has something to do with e.NewEditIndex

I have a sub routine where I pull in information from a database. I want to use variables from this sub routine in another sub routine. I tried making everything public but it doesn't want to be friendly and share.
Dim strEmail as String
Public Sub readDB()
strEmail = "whatever@doohikcy.com"
[Code]....
The readDB would read the database and set the variables and do whatever it needs to do. Then when they submit the form it would e-mail the form to whatever the email address was.

I could really use some help on this. I have been searching for a solution on the web but haven't been able to find much help.I need to add textboxes to a gridview edit cell, based on the number of rows of text in one of the cells. I have coded the capture of the number of textboxes I need to add.
But I am not sure which Gridview event to add the code, when going into edit mode, to run the loop that will insert additional Textboxes in a specific column of the row selected to edit.
The user sees colA that has text with line vbCRLF's embedded say:
"This is sample text."
"Line2"
"Line3"
My code reads three Carriage Return, Line feeds. So when the user goes into Edit mode I want to provide one text box for each line or more accurately, add two more as one will already exist.

In C# when I programmatically need to get a specific control from a GridView, I insert in my RowDataBound event handler:
HyperLink hl = e.Row.Cells[n].Controls[0] as HyperLink;
How can I get the same result in VB? I tried:
Dim hl = CType(e.Row.Cells(n).Controls(0), HyperLink)
and
Dim hl as HyperLink = CType(e.Row.Cells(n).Controls(0), HyperLink)

I also have a bunch of event handlers set up for each item in the context menu. I now want to pass the location of the cell in the datagridview to the event handlers.Do I have to pass the NewPoint() to a public variable and then translate that into a cell location within the event handler?
