Count Particular DataGrid Column Values And Add To Textbox?
Mar 23, 2010
I am using vb.net and WPF. In a wpf window I am showing a datagrid in the load event while in the load event itself, I need to count grand total amount from a single datagrid column and add it to a textbox in same page .
My page looks like this:
My DataGrid:
Item Quantity Total
Shirt 2 200
Pant 1 500
Tie - -
Belt 2 100
My Textbox ---> Grand Total amount : - 800
How do I do that if I am counting from a ((Total Column )) DTG
And adding it and showing it in my (( GRAND TOTAL AMOUNT)) TEXTBOX

Protected Sub invokePagination(ByVal table As DataTable)
'CallPagination() As PagingControlDTO
If table.Rows.Count > 0 Then
Me.DataGridPaging1.Visible = True
[code].....
The code which is underlined is to be replaced.Instead of this I want to use column name to get the total count , since it contain the total count.Column Name is "TOTALROWCOUNT"

I have a DataTable that has several hundred rows.I want to get a row count of distinct values in a particular column.For example, I have a DataTable of Product Orders, but I want to get the number of unique Customers.
I was using this code, but I can't rely on it because my binding source is filtered from time to time.If my binding source has filtered out all rows datatable.DefaultView returns 0 rows.

I have a database and a dataset as the image shows in the link, how would i add the values of the colums "amount1" and "amount2" for every row and entry as the user make entries to be automatically displayed in the "total" column. Meaning that every time values are entered in those amount columns, they will be added and the total displayed in the "Total" column.

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?
Private Sub DataGridView1_ColumnHeaderMouseClick(sender As Object, e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles DataGridView1.ColumnHeaderMouseClick

I have a List of String from which I get all values and the count of each value. This is stored into an IEnumerable variable. So I get a (Value, Count) pair in the IEnumerable. I wish to get only the count from the Value, Count pair depending on the Value. Can I get this in one line of code using LINQ? I did manage to get the value. But how do I display this in the console? Here is my code.
