.net - LINQ Query For Filter By Selected Items In Checkbox List?

Jun 30, 2011

Could not find this through Google or in SO questions.I have a checkbox listbox on my form. I want to filter my List by the list of selected Ids from that listbox that are checked, in SQL I would have done this like "Where TypeId In (1, 4, 5, 7)"... how do I do that in LINQ?

I feel like I am missing a really obvious answer, but cannot get it.

For argument sake... here is the what I have for sample data:

In Colors (List<of currentColors>)
ID, Name, TypeId
1, Red, 1
2, Blue, 1
3, Green, 2
4, Pink, 3

Selected Types 2 and 3 in CheckboxList: filteredColors

Sep 28, 2010

Certain areas of my tab control have become what seams to be transparent using Visual Basic Express 2010. I can rearange items in the tab, except in certain blackhole like areas. When I move a item within the blackhole area or move a item to the blackhole area it disapears to another tab. I can move items out of the blackhole region and they sit where I put them.

DataGridView Get Index Of Selected Column?

May 15, 2010

I have a DataGridView containing a large number of columns. I want the users to be able to select multiple columns and then select a menu item to hide the selected columns. For example a user might selected columns 5 through 10 and I want the program to hide those columns. I know how to hide columns, one at a time. I can get the count of selected columns but I have not figured out how to get the index to the left-most selected column. Trial and error is such a slow process.

Considering the huge number of options offered by the DataGridView tool, it would be nice if this forum had a special category for the DataGridView (common to VB and C#).

Finally I got the desired results but it took a lot of coding, looping through the selected cells to find the one with the lowest column index, then a second loop to count previously-hidden columns, then a third loop for hiding the selected columns, stepping past previously-hidden columns and declining to hide frozen columns.

Validate Selected Column In Datagridview?

Mar 6, 2010

I'm trying to validate that a particular column in a datagridview has been selected.

I've created this code which transfers the value of the selected Customer ID cell in the datagridview to another form.

Private Sub mnuFileEdit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuFileEdit.Click
'Define variable for the current selected cell value

[Code]....

It's working fine but at the moment any column in the datagridview can be selected and transferred which causes an error.

So I want to create an If Then statement which confirms that the selected column with the dgv is the PK_ID (customer ID) column before processing the rest of the code. I've tried playing around with "If dgvCustomerSearch.SelectedColumns("PK_ID") Then" but a "Value of type...cannot be converted to Integer" error occurs.

ComboBox Items From A DataGridView Column?

Jan 8, 2009

I 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.
