如何在Textbox文本上过滤Gridview使用Ajax更改值 [英] How to filter Gridview on Textbox text Changing value using Ajax

问题描述

朋友，我想使用Asp.net中的Ajax在文本框文本更改值上对gridview进行排序或过滤.

friends I want to sort or filter the gridview on textbox text changing value using Ajax in Asp.net

推荐答案

进行排序，对源数据表进行排序.这更有用

例如:

受保护的void gridView_Sorting(对象发送者，GridViewSortEventArgs e)
{
DataTable dataTable = gridView.DataSource作为DataTable;

如果(dataTable！= null)
{
DataView dataView =新的DataView(dataTable);
dataView.Sort = e.SortExpression +" + ConvertSortDirectionToSql(e.SortDirection);

gridView.DataSource = dataView;
gridView.DataBind();
}
}

for sorting, sort source data table. which is more helpful

Eg..

protected void gridView_Sorting(object sender, GridViewSortEventArgs e)
{
DataTable dataTable = gridView.DataSource as DataTable;

if (dataTable != null)
{
DataView dataView = new DataView(dataTable);
dataView.Sort = e.SortExpression + " " + ConvertSortDirectionToSql(e.SortDirection);

gridView.DataSource = dataView;
gridView.DataBind();
}
}
