初学asp.net应该记住的东西

e.Item.Attributes.Add( "onmouseover","this.style.backgroundColor=\""+ "#EFF3F7"+"\"");

}

}

16.模板列

<ASP:TEMPLATECOLUMN visible="False" sortexpression="demo" headertext="ID">

<ITEMTEMPLATE>

<ASP:LABEL text='<%# DataBinder.Eval(Container.DataItem, "ArticleID")%>' runat="server" width="80%" id="lblColumn" />

</ITEMTEMPLATE>

</ASP:TEMPLATECOLUMN>

<ASP:TEMPLATECOLUMN headertext="选中">

<HEADERSTYLE wrap="False" horizontalalign="Center"></HEADERSTYLE>

<ITEMTEMPLATE>

<ASP:CHECKBOX id="chkExport" runat="server" />

</ITEMTEMPLATE>

<EDITITEMTEMPLATE>

<ASP:CHECKBOX id="chkExportON" runat="server" enabled="true" />

</EDITITEMTEMPLATE>

</ASP:TEMPLATECOLUMN>

后台代码

protected void CheckAll_CheckedChanged(object sender, System.EventArgs e)

{

//改变列的选定，实现全选或全不选。

CheckBox chkExport ;

if( CheckAll.Checked)

{

foreach(DataGridItem oDataGridItem in MyDataGrid.Items)

{

chkExport = (CheckBox)oDataGridItem.FindControl("chkExport");

chkExport.Checked = true;

}

}

else

{

foreach(DataGridItem oDataGridItem in MyDataGrid.Items)

{

chkExport = (CheckBox)oDataGridItem.FindControl("chkExport");

chkExport.Checked = false;

}

}

}
