View 3 RepliesGridControl - How To Get Total Number Of Master And Grouped Rows
Jan 25, 2012I found out how to keep track of the currently expanded grouped rows by using 2 events:
- gridview.GroupRowExpanded
- gridview.GroupRowCollapsed
Where I increase or decrement an integer that keeps track of how many group rows are currently expanded. I am now tackling the problem of what to do if the user expands or collapses all of the group rows. I currently know when this is done by checking the e.RowHandle. Any way to find the total number of groups rows currently in the GridView (something like rowcount for normal rows) so I know how many to set the tracking integer to.
For Example: If my current count is 2 and the total number of groups are 15 then when the Expand All is fired the current count is set to 15 rather than 3.
Datagrid With One Column And Dynamic Number Of Rows?
Feb 2, 2009I am trying a small application here. It is a windows mobile application. I have to create a form with one drop down and a datagrid.Once a value is selected in the dropdown. The focus goes to the data grid.I know before hand that there is only one column. But I dont know how many rows the user will enter.When the foucs comes to datagrid then one row is created where the use will enter a number. When he hits tab or enter a new row is created and the cursor goes there and the user can enter second number. When he tabs or etnerts a new row is created. This should go on until he presses Save button when all these values will go in the database table.

View 2 RepliesOrdering Excel Rows By Particular Column Programatically?
Jan 25, 2012I am trying to order 7 rows in descending order of data from a particular column.
The data in the excel spreadsheet looks like this:
Name---Actual----Budget---Budget%
Name1--$2000-----$5000--------40%
Name2--$5000-----$4000-------110%
I want to order the rows by the 'Budget%' column in descending order.

C# - Retrieve Not Empty Rows In First Column Of Excel Sheet
Feb 4, 2011My requirement is to read all rows of an excel-sheet in first column that are not empty, are numeric and have a length between 15 and 20.
For example:
358218033354974
359473035499561
358218036156129
354022038366247
358218032490035
359473030516492
353210040325399
This column might have a header that is not numeric and there might be empty rows. This would cause an exception when importing them via SqlBulkCopy. So i want to prefilter the correct rows via OleDbCommand.
What I have tried so far is following(C# is also appreciated):
Using connection As New OleDbConnection(sExcelConnectionString)
connection.Open()
Dim schemaTable As DataTable = _
connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, _
New Object() {Nothing, Nothing, Nothing, "TABLE"})
[Code] .....
But this throws an exception if there are empty rows or the format of the value is incorrect. So my question is: How to restrict the rows of OleDbCommand to:
Get only first column of every worksheet
All values that are numeric
Skip empty values
Ideally only the values with a length between 15 and 20
Any way how to skip the empty rows, Or do I have to to select the whole datatable? I hoped it would be possible to do that only with one query because of performance reasons.

Get Excel Cell By Row NUMBER And Column Letter?
Jul 19, 2011In VB.NET, using Interop.Excel, I need to access a cell based on a row number and column letter. I tried my luck with...
pages.title = DirectCast(wksht.Cells(rows, "D"), Excel.Range).Value
Since the parameters took type object, I figured maybe this would work, but got no luck. I also thought of enumerating each letter to a number, but the columns in the spreadsheet aren't as normal. Meaning, they're not
A B C D E F G
They're actually...
A B C D E T AZ
I don't know if this makes a difference in the numbering of the columns. The question should be obvious, but just to reiterate, how can I get a cell based on a row number and column letter?

VS 2010 : Combine Similar Rows In A Datatable (the Rows Only Differ By One Column)?
May 8, 2012I have three sub tables that I want to process. For each I want to combine the rows, as they are only different by contents in the second column(I want to do the same to the fourth column, later):
'Sub table 1
