Identify A Datagridview Column Based On Column Name?

Dec 13, 2010

I have a data gridview on my windows form with 4 columns. Now I identify a column as followed:

Dim item1 as String = DataGridView1.Item(1, index).Value

So now I use a number ( In this case: 1 ) for the column index, but I want to make it a bit more readable so now I want to obtain the column index based on the datagridview column name.[code]...

VS 2010 : Select A Column From A Dataset Based On The Value In Another Column?

Nov 15, 2010

I'm writing a help application for the Customer support team at my company to help agents ask better questions when customers report problems. In it, I've got a SQL database that contains all the products, topics, and questions. The layout is similar to the following:

Products Table:
Product_ID Product Name:

Topic_ID Product_ID Topic

I don't know if I'm making myself clear, but I basically need to do the equivalent to the following SQL statement: "SELECT PRODUCT_ID FROM Products WHERE PRODUCT_Name = LstProducts.SelectedValue"

May 30, 2011

I have a datagridview with several columns, but what I�m trying to do is sum km2 column based on date. I�m using the following

DataGridView Cell Formatting To Display Image Based On Another Column Value?

May 7, 2012

I have a SQL database, with some "status" strings. For every status I need to display a .bmp image .

I'm displaying the data from the database via DataGridView with LINQ. In order to display the DGV I have this code:

Me.MyTableAdapter.Fill(Me.TestdbDataSet.MyStatusList)

I was thinking to add another column named "Symbol" and based on the "Status" column to format the cells of the "Symbol" column to display an image.

I edited the DGV, and add a new image column.

I created a directory in my solution called "references" where I put all the .bmp files

I don't know how to do this. My first thought was to put an expression in the DataTable Properties, but I didn't manage to make that work. Another way is to format the cells in the "Symbol" column, and again I don't know how to do that. I tried with "Select Case ... Case ... End Select" with no success.

LE: Should I Insert the .bmp files into SQL database (varbinary(MAX)) If yes, how?

Open Form Based On Value (inside Column) In DataGridView Control

Jun 9, 2011

I am developing a software using microsoft visual studio basic 2010. I used a datagridview control to display a list of data from product table. What I want to do (actually I am not sure how to do it, or is there a way to do it), when I choose one of the value in one of the column inside the table, I want it to open a form that contain data(details) based on that value.
How to do it? How to call the value that I pressed, so it can be used to open a new form containing the details of that value

Example of the data: (the "system" column) SYSTEM
topaz
nex1300
Nec
If I pressed "topaz" system, it will prompt me to a new form containing the details of that "topaz" system.

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?

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

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

Show And Hide Data Based Off Of A Value In A Column?

Feb 16, 2009

I would like to know how I can show and hide data based off of a value in a column.

Example. My table has 3 columns Name, Password, and Tel#

:Pseudo Code
if Name or Column(0).Row(0) = "Shawn" then
. Column(1).Row(0).Forecolor = System.Highlight
. Column(2).Row(0).Forecolor = System.Highlight

[Code].....

I placed my code in the rowprepaint event of the datagridview and on start up I get the results I am looking for. However, if the user selects the row or a cell in the row then the value will display.

I don't want the value to show even if the row is selected.

VS 2008 DGV Display A Column Based On Logic?

Jan 12, 2010

I have a DGV which is part of an inventory system. I have several columns but the ones i need to resolve are Quantity, Name and Plural Name. essentially if quantity is 1 i need to display the Name data if greater than one the plural data. Is this possible? would i need to resolve this earlier in the process (the data is extracted from an xml file using LINQ to bind it to a rowObject) or can i do this with the completed dataset, say by hiding the Name and Plural Name colums and creating a custom column? ideally i would like to keep the data untouched.
