Datagrid With One Column And Dynamic Number Of Rows?

Feb 2, 2009

I 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.

VS 2010 : Combine Similar Rows In A Datatable (the Rows Only Differ By One Column)?

May 8, 2012

I 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

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

Get The Column Name From Column.ColumnName And The Value From Rows(0).Item(0)?

Jul 13, 2011

I have a DataSet that contains 1 DataTable, and the DataTable contains only 1 row of data. I want to loop through all columns in that row and say:

Column name = column value

so for example if the column name is FAVORITE_FOOD and the value is pizza, I should display FAVORITE_FOOD = pizza I can get the column name from column.ColumnName and the value from Rows(0).Item(0), but for the life of me I can't put it all together in a simple loop.

Hide Rows In A Datagrid?

Oct 13, 2011

Our site is developing against a 3rd party API (Wonderware) that returns datasets and datatables from certain calls. The issue we are having with some of the calls is the data returned is more than we want to show to the end users. We are binding the data to a datagrid, and will sometimes get back 20+ columns of data we don't need to show. Is there a way to filter the datatable of columns before binding it to the datagrid? Right now we are using the datagrid to hide the columns, but I think it would be better to strip out the columns of data we don't need before binding to the grid.

Looping Through Rows In A Datagrid?

Mar 27, 2012

For Each row As DataRow In dgrFarms.Rows
Dim sendtroopid As Integer
sendtroopid = row("idColumn")
'Do Something
Next

I've been trying to get a loop through a row in just one column in VB.NET for a while now, and i've done my homework on it too. When i use that code above I get:

Unable to cast object of type 'System.Windows.Forms.DataGridViewRow' to type 'System.Data.DataRow'.

I saw another guide which told me to do:

For Each row As DataGridView In dgrFarms.Rows
sendtroopid = row("idColumn")
'Do Something
Next

But that gives me the error:

Overload resolution failed because no accessible 'Item' accepts this number of arguments.

(That's a blue underline on 'Row("idColumn") )

Numbering Rows In Datagrid?

Jun 9, 2011

numbering rows in datagrid. I have a column that should number 1,2,3 so on when adding a new row. When I delete a row, those numbers should re-number still to 1,2,3. So when I delete row 2, the row that's been added as 3 should now number to 2. Then when I add new rows, these should re-number again, and so on..

My code:
'when adding a new row

My problem is with the for loop when deleting a row.

DataGrid - How To Update Multiple Rows

Feb 27, 2012

I am new to vb.net as well as programming. (Windows application) I have only one data grid, one submit button on form. Datagrid has three columns name, age, salary

User will enter data directly in a row of datagrid. After clicking on save button data will get displayed in grid as well as stored in database.
User also can update data in any row, just by changing cell data of selected row and clicking on save button.

How I can update data in datagrid just by above way? How to guess which row data has changed? If user changes data in multiple rows, how to update multiple rows in this scenario? Can I have to take one extra column in database?

Deleting Rows In Datagrid View?

May 22, 2009

I bring data in from an access database using a sql query and then assign the data to a datagrid view. When i try to delete data from the table, it is removed from the datagrid, but the change is not showing up in the actual table.As a second question, is there a way to tag the specific row and send that back to the actual database for deletion? The way i have it set now, i think would delete all instances where digit, day, and office match, instead of just the selected record.

I have the following code in which it supposed to remove rows that have the first column checkboxes checked, but it only removes one row at a time.If you have more than one checkbox checked, you have to click the command button each time to remove the row.It seems that the logic is correct to remove multiple rows if more than one checkbox is checked, but it doesn't work.
