Resizing Palette programmatically

Thread ID:

Asked On February 2, 2020 11:45 AM UTC


i'd like to resize the diagram palette programmatically at runtime.
This is required because i'd like to offer a simple and an advanced toolset of shapes.

I tried all available state modifier for blazor, but no one seems to have an effect.

        public async Task AdjustPalette()
            optionalPalette.Expanded = !optionalPalette.Expanded;
            this.AdjustSize(); // recalculating size

            await this.Render();
            await this.InvokeAsync(this.StateHasChanged);

        protected void AdjustSize()
            var width = (requiredPalette.Symbols as List<object>)?.Count ?? 0;
            width += optionalPalette.Expanded ? (optionalPalette.Symbols as List<object>)?.Count ?? 0 : 0;

            base.Height = "70px";
            base.Width = $"{width * (base.SymbolWidth + 2)}px";

        protected override void OnInitialized()
            base.Palettes = new List

            base.SymbolWidth = 60;
            base.SymbolHeight = 60;

            base.SymbolMargin = new SymbolMargin { Left = 4, Right = 4, Top = 4, Bottom = 4 };

Hi Manuel, 
We need to bind the SymbolPalette’s Width/Height values to achieve your requirement in blazor component. Please refer to the below code example and sample. 
Code example: 
<input value="UpdateSize" type="button" @onclick="@UpdateSize" name="UpdateSize" /> 
  <EjsSymbolPalette id="symbolPalette" Width="@width" Height="@height" 
                      SymbolWidth="60" SymbolInfo="@SymbolInfo"> 
        <SymbolMargin Left="15" Right="15" Bottom="15" Top="15"></SymbolMargin> 
            <SymbolPalettePalette Id="flowShapePalette" Expanded="true" Symbols="@FlowShapeList" IconCss="e-ddb-icons e-flow" Title="Flow Shapes"> 
            <SymbolPalettePalette Id="connectorPalette" Expanded="true" Symbols="@ConnectorList" IconCss="e-ddb-icons e-connector" Title="Connectors"> 
    //Set width for the palette 
    string width = "20%"; 
    //Set height for the palette 
    string height = "700px"; 
private void UpdateSize() 
        width = "30%";
