Example Diffrent Color For A Specific Value In A Datagridviewcombobox Column
Dec 23, 2010I wanted to visualize to the user the diffrence if they opted for certain values. In mycase certain choises would show phonenumbers on intranet.To show how I wil leave the control names default. To recreate the the project. Start a windows form application, place a datagridview, and 2 bindingsources on the form To start we need some data to show and a list to choose from.To make a simple example I chosen to make a person class containing an Id, Name and Position.Id If the Position is a staff position it should be blue others should remain the default style.But lets start with the colorScheme Interface so we can store the colorscheme we want to show for a certain positionitem in the datagrdview It wil need back and forecolors but also colors for teh item whilst selected. To show the Displaymember we want to see I've also added the toString property that should shadow the toString of the object.[code]
View 2 RepliesMade A Database.mdf That Contains A Table That Includes 3 Diffrent Column Names
Jan 27, 2012I have made a Database.mdf that contains a table that Includes 3 diffrent Column Names.
1:"ID" This one i set to an primary key and i have also made it automaticlly put a number in order to the list. Like 1,2,3,4,5 for each data added. Data Type for this is int.
2:"WordCombination" Were i enter my word combination that i want it to look for)
3."TypeofCombination" Were i enter what the program should add to what i typed in texbox1 if it contains the WordCombination.
I want my program to se if texbox1 contains any of those WordCombinations in my database. And if thats true, Then i want it to show whats in the TypeofCombination + the text in texbox1 in texbox2. If i enter "What do you want ?" in Textbox1 i want the program to find that "What do you want ?" contains "you want" like in ID:1 WordCombination:you want. So becuse this is ture it should enter TypeofCombination in this case "Question:" + what i entered in Textbox1 to show in Textbox2.So if i write "What do you want ?" and click start. Textbox2 should show "Question: What do you want ?" If i Write "My name is Jake" and click start. Textbox2 should show "Answer: My name is Jake".If I Write "hello you Hi there Jacob" and click start. Textbox2 should show "Greeting: hello you Hi there Jacob".And i Should be able to add and delete Word Combinations Without having to change the program.
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
xx|C201 |02300877 |Samsung |....
xx|C201 |02300877 |Toshiba |....
xx|C213 |02300877 |Samsung
[code]....
p.s. For the fourth column, Manufacturer information , I want to do the same and I'd probably get something like this for the final table:
xx| C201,C213,C606,C619 |02300877 | Samsung
xx| C201,C213,C606,C619 |02300877 | Toshiba
xx| C303, C305,C712 |02301163
xx| C207, C209, C708 |02301165

This should go on until he presses Save button when all these values will go in the database table.

Query Dataset Column For Only Rows With Text?
Sep 19, 2009I have a dataset column that I am keeping comments in. If the row has no comment in it(defualt string value is "", not NULL), I don't want it to show up on my report. How can I fill only the datarows that have text in them and not the ones that are empty. I've tried to filter the columns results by Not Nothing, but everything shows up. I'm guessing because it's actually not NULL since the string is "". How can I filter these results correctly?
View 2 RepliesC# - 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.
