Hi Jim,
Initially, please remove the symbolpalette’s DiagramId property which you have defined in aspx.cs file and set it in the diagram create event, so that you can drag the shapes from the palette once the diagram is rendered. Please refer to the code example.
Code example:
SymbolPaletteProperties symbolpalette = new SymbolPaletteProperties();
//remove the diagramId property
//symbolpalette.DiagramId = "DiagramContent";
DiagramContent.OnClientCreate = "create";
function create() {
$("#symbolpalette").ejSymbolPalette({
diagramId: "DiagramContent",
});
}
Regards,
Shyam G
