find A row in DataGridview using datarow values

Posted 08 July 2010 - 06:49 AM

hi ,
i have a Datagridview which am populating from a datatable, am not using databinding here , jsut populating from the datatable column by column.
1. if the value is not present in the datagridview then add the row and make the row as some green color.
2. If the datarow of datatable is present in the datagridview mark it as Gold color.

I have seen so many topics in the net ... but they all use datagridviewrow.indexof(datagridviewrow) to find out if row in present in the datagridview , provided the row has been selected by the user.
Queries

1 .how to find that a particular row is present in the datagridview?
                                            DataGridViewRow row1 =new DataGridViewRow();
                                            row1.CreateCells(datagridview1, someObjectarrayValuesAlsoPresentinDataGridView[]);
int ind = datagridview1.Rows.IndexOf(row1);
datagridview1.Rows[ind].DefaultCellStyle.BackColor = Color.Gold;



this doesnt work...
ind values always comes as -1.
datagridview1.Rows[ind].DefaultCellStyle.BackColor = Color.Gold;

throws as exception Index value out of range.
Is there any way it can be implemented.
bool value = datagridview1.Rows.contains(row1);


this also returns false all the time.

Y the indexof(row) nt working.... though the row gets populated with correct cell values.
Note: My row is not selected by the user.

Is This A Good Question/Topic? 0

This had me thinking for a while as it's been a while since I've used a DGV, and don't have VS to test.

This *should* work to select the row number

int rowNumber = dgvdata.CurrentCell.RowIndex;


Also theres a property to select the entire row when the cell is clicked, the property SelectionMode can be used for this if that's what you want.

Feel free to post again if you need help, I'm a tired atm so I only briefly read your post :sleep1:
