I have a grid view in which I want to show images whose paths are stored in a database. I have tried this code but it repeats only one picture in all rows. Can anyone help me to solve this problem? I don't want to use the customunboundcolumn event. My code is shown below
SqlCommand cmd = new SqlCommand("select * from picture", con);
SqlDataAdapter adp = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();
adp.Fill(ds);
gridControl1.DataSource = ds.Tables[0];
DevExpress.XtraGrid.Columns.GridColumn image = new DevExpress.XtraGrid.Columns.GridColumn();
gridView1.Columns.Add(image);
image.Caption = "Image";
image.Name = "img";
image.FieldName = "img";
image.Visible = true;
image.VisibleIndex = 3;
int row = ds.Tables[0].Rows.Count;
DevExpress.XtraGrid.Views.Base.ColumnView cgv = (DevExpress.XtraGrid.Views.Base.ColumnView)gridView1;
DevExpress.XtraEditors.Repository.RepositoryItemImageEdit rpic = new DevExpress.XtraEditors.Repository.RepositoryItemImageEdit();
rpic.NullText = "No Image";
rpic.SizeMode = DevExpress.XtraEditors.Controls.PictureSizeMode.Zoom;
DevExpress.Utils.ImageCollection images = new DevExpress.Utils.ImageCollection();
for (int i = 0; i < row; i++)
{
string imgpath = ds.Tables[0].Rows[i]["fpath"].ToString();
images.Images.Add(Image.FromFile(imgpath));
rpic.Images = images;
gridView1.Columns["img"].ColumnEdit=rpic;
gridView1.SetRowCellValue(i,"Image",rpic);
gridView1.SelectRow(i);
MessageBox.Show(gridView1.FocusedRowHandle.ToString());
// gridView1.SetFocusedRowCellValue("Image",gridView1.Columns["img"].ColumnEdit= rpic);
}
gridView1.BestFitColumns();
You need to make your ColumnEdit as a RepositoryItemPictureEdit
RepositoryItemPictureEdit rePictureEdit = gridControl1.RepositoryItems.Add("PictureEdit") as RepositoryItemPictureEdit;
rePictureEdit.NullText = " ";
rePictureEdit.SizeMode = PictureSizeMode.Squeeze;
columnName.ColumnEdit = rePictureEdit;
Then
columnName.Value = Image.FromFile($@"{imagePath}");
