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.

Hidden Column In ListBox?

Jun 22, 2010

I select four columns(those are informations about payed fee for each member...so it could have zero or more rows) from my database (from two different tables), one record as "ID" and other three (i've band them together) as "Rest".Then, I've put that column "Rest" as a DisplayMember for my first ListBox...because I couldn't find a solution to put that "ID" column in the same ListBox, and make it invisible for user (I need "ID" column for accessing those fields about payed fee) I've made another ListBox and set DisplayMember = "ID".

I've put that ListBox on Visible=False and when I select rows from first ListBox "ID" is also changing and on event "SelectedIndexChange" for first ListBox I'm trying to get this "ID", store it into Integer variable and then put it into another select query that will select only selected pay fee from database...everything of this works fine but when I try to put that data from the last select query (something like this: TextBox3.Text = dataTablePodaci.Rows(0).Item(1) ) to a different textboxes (because there are three columns in select) here comes the problem, suddenly. The thing is that I can't see my real records in the main ListBox anymore...and instead of that for all rows I get:

Get All The Id (hidden Column) Of All Check Items?

Jun 18, 2012

I 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.

Datagridview Seems To Cause Startup Form To Appear Even After Been Hidden?

Feb 15, 2010

I have created a DB with access and imported it into my application. What I am trying to do is startup with regi.vb and test to see if there are any entries into the DB and if so, hide the startup form(regi.vb) and show the login.vb form. have done a test and it loads regi.vb then I enter some details into the textboxes and then after clicking a button, it inserts the info from the textboxes into the DB. It then loads login.vb, which is fine, but then if i exit the app and reload it, it tests to see if there is anything in the DB and when it finds that there is, it reloads the bloody regi.vb(startup form)!!So why, when it discovers that the DB is not empty, it re-opens the startup form??

I have used login.show()
me.hide()
Here is the code for the startup form (regi.vb)

Datagridview - Sort Datagrid View Column With Numbers And Texts On Column Header Click?

Feb 13, 2012

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?

Show Bit Column As A Checkbox Column In Unbound Datagridview

May 14, 2010

Dim Comp = From C In db.Table1 _
Select C.Completed, C.Taken, C.Namne
Datagridview1.DataSource = Comp

Am using the Entity Framework and Columns Completed and Taken are of bit Datatype. When the query results are displayed in the datagridview, these bit columns are returned as of ColumnType Textbox - so i get a Datagridview textbox column with true or false string values.

I want to display Completed and Taken as Checkbox columns (either ticked for True or un-ticked for false) but ofcourse i can't do this in EditColumn dialogue because the Datagridview is unbound.

how can i change this in code at runtime
