Adding Values From ArrayList To Particular Column Of GridView?
Jan 24, 2011
I am trying to add values from Arraylist to particular column of grid view.
As:
If (Arr_NewContacts.Count > 0) Then
dgvStayout.Rows.Clear() ' **GETTING ERROR HERE**
dgvStayout.Rows.Insert(0, (Arr_NewContacts.Count - 1))
For i As Integer = 0 To Arr_NewContacts.Count - 1
dgvStayout.Rows(i).Cells("Name").Value = Arr_NewContacts(i).ToString
[Code] ......
Datagrid property like AllowUserToAddRows and AllowUserToDeleteRows is already set to true.I am using above code on lost focus event of one of text box.
Public Class BasicInformation Public maleFirstNames As New ArrayList Public maleFirstNames.Add("John") Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
I want to declare a set of arraylists and the base values so that they are available throughout the entire program. When I set the declaration for the array list as public and attempt to add a value to the array the add.("john")is underlined in blue and it says end of statement is expected.

I have been trying to modify the data going into a column by adding spacing to the start of the column before the Row ID, using the level to multiply the amount of spaces.Ie. ID is SVG00098 and is a Level 3 Asset, so it requires 6 spaces before the ID.
I just want to ask the following infor from you in relation to gridview... I have 3 Grids, Grid A Grid B Grid C
Grid a has already a data but aside from the data in my grid A I want to add another column for a checkBox. Next, when the checkbox is check and I hit the button "Transfer" the row in the grid in where the additional column checkbox has been check will be transfer to grid B and the remaining data will be move to Grid C?
I use GridView to show/edit data in the database. In the GridView there are two columns called mark1 and mark2. What I want to do is when user clicks update, the program should check if the values entered at mark1 and mark2 sum to 100. If they don't the program should cancel the update and show an error message. How do I do it? I use ASP.NET with VB.
Please can you translate the above line of C# into VB.NET?At runtime, I'm trying to update an existing GridView column, as opposed to adding new columns, just before a DataBind()

Rows no 1 to 4 has 'High', 'High'. I want make them gray bgcolor for those rows. Rows no 5 to 8 has 'High','Low'. I want make them white bgcolor for those rows Rows no 9 to 12 has 'High','Medium'. I want make them again gray bg color for those rows.
I have an unbound Gridview that is populated by a Linq to Entities query and would like to convert string values in a particular column to lowercase. In the Gridview's RowDataBound event, I have tried StrConv(e.Row.Cells(3).Text, VbStrConv.ProperCase) but this doesn't work. I have also tried StrConv(emp.Name, VbStrConv.ProperCase) in the LiNQ to Entities query but still the Name values returned are to converted to Lower-case.
Protected Sub GridView3_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView3.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then For i As Integer = 0 To e.Row.Cells.Count - 1 Dim cellDate As Date [Code] .....
I want to add all the values of a certain column. I already get the value of an exact cell value but when i add the loop code for it to continue,it doesn't performs well.
i have a datagridview and in one of the columns i m storing the amount on button click...i want to add the values of the amount at that time only i have done this but it is displaying 0 in the required textbox total += Form1.DataGridView1.Rows(counter - 1).Cells(6).Value
When I implement this code, the first time the button is activated, the values are placed in the array, and displyed in the list box. However if the user then selects more days and times to add to the list box, and activates the button again, the previously added entries in the array are erased, and only the new entries are displayed. How can I prevent previous entries from being erased? If the user wants to add values, they need to be added to the existing values.[code]
I have a datagridview that is populated from an Oracle 11g DB. What I would like to do is add the values of a column together and display the results in a textbox. What would be the easiest way to do this?
I have a function that returns a list of account numbers as an Arraylist. I am trying to use each account as a command parameter in another sub routine to get more data about each account number. This only returns the data for the last account number in the arraylist. I need to use each account number, call the database, get the additional information and store ALL of the data into a Gridview (databind). Example: If I had 3 account numbers in my arraylist return 3 rows of data to the gridview. I am struggling with how to get ALL of the information for each value (account number) in the Arraylist. Can someone point me in the right direction?? I think this can be done but I am not certain if my approach is correct or not. Perhaps I need to create datatables that contain the additional information for each value passed via the arraylist.
Private Function ReturnMultAccts(ByVal strAcct) As ArrayList Dim acctsDetail As New ArrayList Dim dsn As String = Configurati
am trying to calculate the values in rows in column 6 based on values of column 5. Bellow is the the code I am using I get a run time error about the string not formatted properly
VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.
I'm trying to do is take each item from an arraylist, that is populated through a structure read from textfiles, then loop through them adding each result from the arraylist to a new line in a textbox. What I'm getting is that it's adding only the last item to the textbox rather than listing them, yes I have multiline set to true. Because of the potential size of the arraylist I have it running in a background worker. Once it's complete then I'm trying to populate the textbox. All the code is working fine to that point it's just populating the textbox correctly is my problem.[code]I've tried adding vbnewline, vbcrlf, cblf at the end of the statement as well as placing the text statement in both the runworkercompleted sub as well as in the delegate with the same result.
I'm wondering if this is possible, I want to be able to call functions from within the program itself by means of an ArrayList? I want to be able to do something such as:
FunctionsList.Add(SomeFunction) FunctionsList.Add(SomeSub) For Each Function in FunctionsList Call Function Next
Would this be possible? It's important for a project I am working on.
i am trying to add items to a Listbox, but first i need to know if the item is already in ListBox. I know how to compare the selected item in a combo with the arraylist. I use this
If Indicadoreslist.Contains(Me.ComboBox2.SelectedValue) Then MsgBox("It exists") Else...
Channels is a dynamic arraylist which lists all the different channels of the fixture. A channel could be the lights colour or its intensity. A channel has the following properties:
Type, FeatureGroup, Value, Universe, Address, Slots and Offset.
Slots is the same again, breaking down to another ArrayList with more details.
Code:
Private Sub Patchingtest() Dim TestFixture As New Fixture_Structure Dim Intensity As New Channel
I have a function which iterates through the TextBoxes in my form (and its child controls) and adds each TextBox's name and text to an ArrayList using a structure I called valTxtBox.
Here's a snippet of the VB.NET Public Structure valTxtBox Public nome As String Public texto As String End Structure [Code] .....
Now, the problem is that if I call Clear() for valsTxtBox in the getctrls() function, not all the elements get added to the ArrayList. However, if I don't call Clear() it works just fine. BTW, I'm using VS2008 express which might be relevant.
I found that if using ArrayList, all clone/CopyTo/Add command are shadow copy, not separate copy. How can I do such that after an ArrayList A is "copied" to ArrayList B, change in ArrayList A will not reflect to ArrayList B?
I am struggling with a simple datatable issue. The following takes a data table that is on the form and adds an arraylist to it as the data source. The data that shows up in the datatable is the length of the value of the element in the arrayList.
How do I control what is displayed in the columns? What I am ultimately trying to do is have a datatable that the operator can edit and the changes reflect in the underlying data structure.
I'm completely new to VB.NET and this is likely a few steps over my head, but have managed to get myself this far with just Google.I'm reading an XML file and creating an arraylist of classes for the values in there, as seen:
Public Class yresults 'Dim xdate As XmlNodeList = xDoc.GetElementsByTagName("Date") 'Dim link As XmlNodeList = xDoc.GetElementsByTagName("Link")
