One way you can do this is to use the CellsPainting event to draw the bitmap for a particular header cell. Here is code that does this assuming the bitmap is in an imagelist. //this.images is an ImageList with your bitmaps void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e) { if (e.ColumnIndex == 1 && e.RowIndex == -1) … Read more
private void dataGridView1_KeyDown(object sender, KeyEventArgs e) { e.SuppressKeyPress = true; int iColumn = dataGridView1.CurrentCell.ColumnIndex; int iRow = dataGridView1.CurrentCell.RowIndex; if (iColumn == dataGridView1.Columncount-1) { if (dataGridView1.RowCount > (iRow + 1)) { dataGridView1.CurrentCell = dataGridView1[1, iRow + 1]; } else { //focus next control } } else dataGridView1.CurrentCell = dataGridView1[iColumn + 1, iRow]; }
Well, since this is a datagridview… Sorry for the ‘winforms’ in the question… but I could just do this.. scrolling up or down one row. Scroll up: this.FirstDisplayedScrollingRowIndex = this.FirstDisplayedScrollingRowIndex – 1 Scroll Down: this.FirstDisplayedScrollingRowIndex = this.FirstDisplayedScrollingRowIndex + 1; You’ve gotta make sure to check that the numbers don’t go out of bounds though.
Show Image On Button You can add a DataGridViewButtonColumn, then handle CellPainting event of the grid and check if the event is raised for your button column, then draw an image on it. At the end of event, don’t forget to set e.Handled = true;. In the below code I suppose you have an image … Read more
There are many ways to do this, but the following is the simpliest and it will do what you want and get you started. Create a public method on your main form. Modified constructor of second form to take a main form. Create an instance of the second form passing the main form object. When … Read more
Take a look at this MSDN page and this blog post. In principle, you need to configure the sorting at the data source (whether its an ObjectDataSource or a SqlDataSource) not at the GridView. As far as I can tell the DataView class doesn’t support anything other than a simple ascending/decending sort. Without seeing the … Read more
ListChanged notifications for item value changes are only raised if the list item type implements the INotifyPropertyChanged interface. Taken from: http://msdn.microsoft.com/en-us/library/ms132742.aspx So my first question would be: Implements your item the INotifyPropertyChanged properly?
I added class DataGridViewProgressColumn.cs (source: MSDN) using System; using System.Collections.Generic; using System.Text; using System.Windows.Forms; using System.Drawing; using System.ComponentModel; namespace Sample { public class DataGridViewProgressColumn : DataGridViewImageColumn { public DataGridViewProgressColumn() { CellTemplate = new DataGridViewProgressCell(); } } } namespace Sample { class DataGridViewProgressCell : DataGridViewImageCell { // Used to make custom cell consistent with a DataGridViewImageCell … Read more
Here’s your code fixed up. Next forget bindingsource var select = “SELECT * FROM tblEmployee”; var c = new SqlConnection(yourConnectionString); // Your Connection String here var dataAdapter = new SqlDataAdapter(select, c); var commandBuilder = new SqlCommandBuilder(dataAdapter); var ds = new DataSet(); dataAdapter.Fill(ds); dataGridView1.ReadOnly = true; dataGridView1.DataSource = ds.Tables[0];
You can do like this: private void datagridview1_SelectionChanged(object sender, EventArgs e) { if (datagridview1.SelectedCells.Count > 0) { int selectedrowindex = datagridview1.SelectedCells[0].RowIndex; DataGridViewRow selectedRow = datagridview1.Rows[selectedrowindex]; string cellValue = Convert.ToString(selectedRow.Cells[“enter column name”].Value); } }
