Hello Steve,
Thank you for contacting us.
There was an issue in the layout of
RadPanorama which was causing such exception when you dynamically add items. You can workaround it by suspending the layout of the
RadPanoramaElement while adding tiles. The issue is no longer present in the latest version.
I have also noticed a small issue in the sample code you have posted. Please note that the
RadPanorama.RowsCount property sets the number of rows when you are not using groups. In grouped view, each group has its own
RowsCount property and in your case you should use
tileGroupElement1.RowsCount.
The following code snippet demonstrates how to overcome the above mentioned issue:
public Form1()
{
InitializeComponent();
this.tileGroupElement1.RowsCount = 5;
}
private void radButton1_Click(object sender, EventArgs e)
{
this.radPanorama1.PanoramaElement.SuspendLayout(true);
foreach (string img in Directory.GetFiles(@"C:\images", "*.png"))
{
AddNewImageTile(img);
}
this.radPanorama1.PanoramaElement.ResumeLayout(true, true);
}
private void AddNewImageTile(string ImagePath)
{
if (File.Exists(ImagePath))
{
RadTileElement newTile = new RadTileElement();
newTile.AutoSize = true;
newTile.AutoSizeMode = Telerik.WinControls.RadAutoSizeMode.Auto;
newTile.GradientStyle = Telerik.WinControls.GradientStyles.Linear;
newTile.Image = Image.FromFile(ImagePath).GetThumbnailImage(64, 64, null, IntPtr.Zero);
newTile.ImageAlignment = System.Drawing.ContentAlignment.BottomLeft;
newTile.Padding = new System.Windows.Forms.Padding(15);
newTile.TextImageRelation = System.Windows.Forms.TextImageRelation.TextAboveImage;
newTile.Row = tileGroupElement1.Items.Count % this.tileGroupElement1.RowsCount;
newTile.Column = tileGroupElement1.Items.Count / this.tileGroupElement1.RowsCount;
this.tileGroupElement1.Items.Add(newTile);
}
}
