change datagridview row color (winform 2.0)

change datagridview row color (winform 2.0)

• DaveKoch

  Dear Friends
  
  I have a requirement to color data grid row back color based on a given condition ( that is for a given column).
  
  But when I run the code above it doesn't color grid cells. The event I am using is form's Load event or button click event.
  
  Please help me to solve this issue.
  
  Thanks

  I assume you mean "based" on condition of column What specific condition are you looking for. Are you looking to change the one cell in a column, or the whole row based on a column setting, or did you mean based on the condition of the row
  
  There are a ton of events for changes to columns as well as rows in the DataGridView class. Look through the list and you may find what you need. The DataGridViewRow class provides a DefaultCellStyle property that defines row-specific styles, and the DataGridView class has an AlternatingRowsDefaultCellStyle property that applies to every other row.
  
  These and other DataGridView members are discussed in chapter 21 of my new book, if you're looking for a paper reference.

  Hi,

  How can I change the color of the entire row based on a cell value.

  Lets say Column "CustomerID" in a Rowcell has value 4 and this row should become red on DataGridView at fill time.

  Ah, so you're looking to assign the row background based on the condition of a cell within that row.
  
  Again, there are all sorts of events to track what changes when. The most basic for this purpose might be the CellValueChanged event, which occurs when a cell's value changes. For example, the following code sets the background color to Red when the string value associated with a cell is changed to "High"
  
  private void myDataGridView_CellValueChanged(object sender, DataGridViewCellEventArgs e)
  {
  int colIndex = e.ColumnIndex;
  int rowIndex = e.RowIndex;
  
  if (rowIndex >= 0 && colIndex >= 0)
  {
  DataGridViewRow theRow = dataGridView1.Rows[rowIndex];
  if (theRow.Cells[colIndex].Value.ToString() == "High")
  theRow.DefaultCellStyle.BackColor = Color.Red;
  }
  }

  is there a way to check the char instead of whole string

  example. "High" , i want to check the letter H. if H exist then color this cell.

  Just change (theRow.Cells[colIndex].Value.ToString() == "High" from above to

  (theRow.Cells[colIndex].Value.Contains("H"))

  Hai

  private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
  {
  // If the column is the Artist column, check the
  // value.
  if (this.dataGridView1.Columns[e.ColumnIndex].Name == "Artist")
  {
  if (e.Value != null)
  {
  // Check for the string "pink" in the cell.
  string stringValue = (string)e.Value;
  stringValue = stringValue.ToLower();
  if(stringValue == "high")

  {
  e.CellStyle.BackColor = Color.Pink;

  }

  }

  }

  }
