I\'m developing user control in C# Visual Studio 2010 - a kind of \"quick find\" textbox for filtering datagridview. It should work for 3 types of datagridview datasources:
You could create a DataView object from your datasource. This would allow you to filter and sort your data without directly modifying the datasource.
Also, remember to call dataGridView1.DataBind(); after you set the data source.
dataGridView1.DataBind();
