Extends DataGrid Functionalities

Sample Image - GridEx.jpg

Introduction

This is an enhanced DataGrid that built in with Auto Search, Auto Column Sizing and Row Select features. In addition, it supports multiple Tablestyles binding to single DataTable. New events such as CurrentRowChanged and OnHeaderClick also have been included.

Background

This component was created out of frustration with default datagrid controls. After searching around from web but could not find a Free datagrid control with the features that suit my needs. I decided to create one by myself. This is my first .NET component, feel free to give me feedbacks or comments so that I can learn something and improve my .NET skill. I hope this component is useful to those of you who are as frustrated as me.

GridEx

Property Description
AutoSearch Enable or disable auto search function in datagrid.
AutoSize Enable or disable column auto sizing in datagrid.
RowSelect Enable or disable row select in datagrid.
CurrentStyeIndex Gets or sets a value indicating current TableStyle. Default value is -1.
UseGridParentStyle Gets or sets a value indicating whether TableStyles should follow the grid style.

Method Description
OnHeaderClick Raises HeaderClicked event.
OnCurrentRowChanged Raises CurrentRowChanged event.

Event Description
CurrentRowChanged Occurs when current row has changed.
HeaderClicked Occurs when grid header is clicked.

How to use AutoSearch in GridEx

Set AutoSearch property to true during design time or use the following code during runtime:-

...
this.gridEx1.AutoSearch = true;

During runtime, simple click on the header column that you want to perform search and then type in search value and GridEx will perform incremental search for you. You may use [Backspace] to delete char or [Escape] to clear search value. If you search on DateTime column type, a datetime input box will appear.

Creating Multiple TableStyles

Create styles using datagrid TableStyles Editor. Set the style's MappingName to TableName of DataTable if you want GridEX to load this style first. If none of the styles has MappingName assigned, default style will be used.

Changing TableStyles at Runtime

To change style at runtime, set CurrentStyleIndex to a valid TableStye index.

...
this.gridEx1.CurrentStyleIndex = 1;

Setting CurrentStyleIndex to -1 will tell GridEx to use default style.

Limitation

AutoSearch only supports DataTable and DataView datasource. AutoSearch will be turned off automatically if you assign a DataSet to datagrid DataSource property.
