View 3 RepliesComboBox Items From A DataGridView Column?
Jan 8, 2009I have a DataGridView control with two columns:
colName
colAnnounceURL
I also have a ComboBox that I need to bind to the colAnnounceURL in the DataGridView. So everytime I add new rows to the DataGridView, the ComboBox will be updated with the items in colAnnounceURL.
I have tried the following to no avail:
cboAnnounceURL.DataSource = dgvTrackers
cboAnnounceURL.DisplayMember = "colName"
cboAnnounceURL.ValueMember = "colAnnounceURL"
The code does not cause a crash but does nothing.
Both controls are visible to the user. The idea is to have DataGridView act as AnnounceURLs manager and ComboBox to set the active AnnounceURL.
Get All The Id (hidden Column) Of All Check Items?
Jun 18, 2012I have this issue right now. I have a listview with checkbox. Now what I want to achieve is get all the id (hidden column) of all check items and pass it to arraylist so that I can pass it to SQL like this:
dim intProductID as new arraylist
For i = 0 To lv_list_products.Items.Count - 1
If lv_list_products.Items(i).Checked = True Then
[Code].....
"DELETE * from t_products WHERE f_product_id in(" & intProductID & ")" The reason I do this is to have only one time open of database connection, One of the member suggested it is not good to open and close database specially if it is within the loop. One more issue is the command within the array I need to separate all id with commas so I will not have error on SQL.

View 5 RepliesVS 2010 - How To Get Number Of Items In Each Column In 2 Dim Array
Mar 14, 2011When you have a single dim array, you get number of items in with simple Ubound(array). What is the most efficient way, to get number of items in each "column" in 2 dimensional array? My code (part):
.NET
Public Shared LoopStock()() As LoopStockDef
Public Structure LoopStockDef
Dim EntID As Int32
Dim LoopNo As Int16
Dim LoopType As String
Dim loopStPtX As Int32
[Code] .....
You can't Ubound multidimensional array as you can do with single dimensional array, as the second dimension can have different number of items in each column (DimX in the following table)
DimX | (1) | (2) | (3) | (4) | (5) |
-----------------------------------------------
DimY | | | | | |
(1) | 45 | 41 | 15 | 48 | 49 |
(2) | 35 | 26 | 98 | 15 | 31 |
(3) | 12 | 23 | 36 | 69 | |
(4) | 88 | | 26 | 28 | |
(5) | 74 | | 89 | | |
(6) | 36 | | 25 | | |
If you do
.NET
UBound(LoopStock, 2)
You get size of 2nd dimension, not number of items in the table for particular column. The best solution which comes to my mind is to define another array, a multidimensional counter, like
.NET
LoopStockDims() As Int16
And count every added item for each column. Is this the best way?

View 1 RepliesVB GridView Control Does Not Allow Code To Access Column When Column Has Visible Property Set To False
Apr 1, 2010VB 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.

View 1 RepliesDatagridview - Sort Datagrid View Column With Numbers And Texts On Column Header Click?
Feb 13, 2012It 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?
