+# WPF GridControl input message
+
+This repository contains the samples that demonstrates various options in input message feature of [WPF GridControl](https://help.syncfusion.com/wpf/gridcontrol/overview).
+
+### Input Message Tip for row and column
+
+The input message tip can be displayed for any row or column by setting the [ShowDataValidationTooltip](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Controls.Grid.GridStyleInfo.html#Syncfusion_Windows_Controls_Grid_GridStyleInfo_ShowDataValidationTooltip) and the message tip can be customized by setting [DataValidationTooltip](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Controls.Grid.GridStyleInfo.html#Syncfusion_Windows_Controls_Grid_GridStyleInfo_DataValidationTooltip) property.
+
+``` csharp
+//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.
+
+``` csharp
+//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](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Controls.Grid.GridModel.html#Syncfusion_Windows_Controls_Grid_GridModel_QueryCellInfo) event.
+
+``` csharp
+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](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Controls.Grid.GridStyleInfo.html#Syncfusion_Windows_Controls_Grid_GridStyleInfo_DataValidationTooltipTemplateKey) property. If you are using inputTextmessage1 then you need to assign template to its corresponding template key property namely `GridStyleInfo.DataValidationTooltipTemplateKey`.
+
+[GridStyleInfo](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Controls.Grid.GridStyleInfo.html) which holds cell information is the `DataContext` for data template of input message tip.
+
+#### XAML
+
+``` xml
+<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#
+
+``` csharp
+// 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";
+    }
+}
+```
