WPF GridControl Input Message

This repository contains the samples that demonstrates various options in input message feature of WPF GridControl.

Input Message Tip for row and column

The input message tip can be displayed for any row or column by setting the ShowDataValidationTooltip and the message tip can be customized by setting DataValidationTooltip property.

//Adding input message tip for specific row
grid.Model.RowStyles[1].DataValidationTooltip = "Hello";
grid.Model.RowStyles[1].ShowDataValidationTooltip = true;

//Adding input message tip for specific column
grid.Model.ColStyles[1].DataValidationTooltip = "Hello";
grid.Model.ColStyles[1].ShowDataValidationTooltip = true;

An another way to set the input message tip for specific row and column.

//Add input message tip for specific row
for (int i = 1; i <= 4; i++)
{
    string comment = grid.Model[1, 0].CellValue + " :\nPopulation rate in " + grid.Model[1, i].ColumnIndex + " is " + grid.Model[1, i].CellValue;
    grid.Model[1, i].DataValidationTooltip = comment;
    grid.Model[1, i].ShowDataValidationTooltip = true;
}

//Add input message tip for specific column
for (int i = 1; i <= 4; i++)
{
    string comment = grid.Model[i, 0].CellValue + " :\nPopulation rate in " + grid.Model[i, 2].RowIndex + " is " + grid.Model[i, 2].CellValue;
    grid.Model[i, 2].DataValidationTooltip = comment;
    grid.Model[i, 2].ShowDataValidationTooltip = true;
}

Set Input Message Tip using QueryCellInfo event

You can set the input message tip for specific cell or row or column by using QueryCellInfo event.

private void Grid_QueryCellInfo(object sender, Syncfusion.Windows.Controls.Grid.GridQueryCellInfoEventArgs e)
{
    e.Style.ShowDataValidationTooltip = true;

    //Show message tip for specific cell
    if (e.Cell.RowIndex == 1 && e.Cell.ColumnIndex == 1)
        e.Style.DataValidationTooltip = e.Style.GridModel[1, 0].CellValue + ": \nPopulation rate in " + e.Style.ColumnIndex + " is " + e.Style.CellValue.ToString();
    
    // Show message tip for row.
    if (e.Cell.ColumnIndex > 0 && e.Cell.RowIndex == 1)
        e.Style.DataValidationTooltip = e.Style.GridModel[1, 0].CellValue + ": \nPopulation rate in " + e.Style.ColumnIndex + " is " + e.Style.CellValue.ToString();
        
    // Show message tip for column.
    if (e.Cell.RowIndex > 0 && e.Cell.ColumnIndex == 2)
        e.Style.DataValidationTooltip = e.Style.GridModel[e.Style.RowIndex, 0].CellValue + ": \nPopulation rate in " + e.Style.RowIndex + " is " + e.Style.CellValue.ToString();
}

Customize the Input Message Tip

The input message tip can be customized by defining DataTemplate. The DataTemplate can be assigned to the GridStyleInfo.DataValidationTooltipTemplateKey property. If you are using inputTextmessage1 then you need to assign template to its corresponding template key property namely GridStyleInfo.DataValidationTooltipTemplateKey.

GridStyleInfo which holds cell information is the DataContext for data template of input message tip.

XAML

<Window.Resources>
    <DataTemplate x:Key="inputTextmessage1">
        <Border BorderBrush="Gray" BorderThickness="2.5" CornerRadius="5">
            <TextBlock Width="Auto" Height="Auto" HorizontalAlignment="Left" VerticalAlignment="Center" Background="LightBlue" FontSize="14" Foreground="Black" Text="{Binding DataValidationTooltip}" />
        </Border>
    </DataTemplate>
</Window.Resources>

C#

// Set template key to a particular index 
grid.Model[1, 2].DataValidationTooltipTemplateKey = "inputTextmessage1";

// Using QueryCellInfo event
private void Grid_QueryCellInfo(object sender, Syncfusion.Windows.Controls.Grid.GridQueryCellInfoEventArgs e)
{
    if(e.Cell.RowIndex == 1 && e.Cell.ColumnIndex == 2)
    {
        e.Style.DataValidationTooltip = e.Style.GridModel[1, 0].CellValue + ": \nPopulation rate in " + e.Style.ColumnIndex + " is " + e.Style.CellValue.ToString();
        e.Style.ShowDataValidationTooltip = true;
        e.Style.DataValidationTooltipTemplateKey = "inputTextmessage1";
    }
