一个 gridview 有 “edit”按钮，可以编辑数据，
我想实现一个点击一行任何地方时就选中当前行的功能，
添加了如下代码：
protected override void oninit（eventargs e)
{
base.oninit（e);
initializecomponent（);
}
private void initializecomponent（)
{
gv_master.rowcommand += new gridviewcommandeventhandler（gv_master_rowcommand);
}
protected void gv_master_rowdatabound（object sender, gridviewroweventargs e)
{
// set single_click event to every column
if （e.row.rowtype == datacontrolrowtype.datarow)
{
// get the linkbutton control in the first cell
linkbutton singleclickbutton = （linkbutton)e.row.cells[0].controls[0];
// get the javascript which is assigned to this linkbutton
string jssingle = clientscript.getpostbackclienthyperlink（singleclickbutton, " ");
// add events to each editable cell
for （int columnindex = m_ifirstcolumn; columnindex < e.row.cells.count; columnindex++)
{
// add the column index as the event argument parameter
string js = jssingle.insert（jssingle.length - 2, columnindex.tostring（));
// add this javascript to the onclick attribute of the cell
e.row.cells[columnindex].attributes[ "onclick "] = js;
// add a cursor style to the cells
e.row.cells[columnindex].attributes[ "style "] += "cursor:pointer;cursor:hand; ";
}
}
}
#region render override
// register the dynamically created client scripts
protected override void render（htmltextwriter writer)
{
// the client events for gridview1 were created in gridview1_rowdatabound
foreach （gridviewrow r in gv_master.rows)
{
if （r.rowtype == datacontrolrowtype.datarow)
{
for （int columnindex = m_ifirstcolumn; columnindex < r.cells.count; columnindex++)
{
page.clientscript.registerforeventvalidation（r.uniqueid + "$ctl00 ", columnindex.tostring（));
}
}
}
base.render（writer);
}
#endregion
protected void gv_master_rowcommand（object sender, gridviewcommandeventargs e)
{
gridview gridview = （gridview)sender;
int rowindex = int.parse（e.commandargument.tostring（));
switch （e.commandname)
{
case （ "single_click "):
gv_master.selectedindex = rowindex;
break;
default:
break;
}
}
选中的功能实现了，但是“编辑”按钮不起作用了。请赐教 |
