</asp:GridView>
在我的CS我有...
in my cs I have...
private static string strColorUrgente = "#FF525D";
private static string strColorEnCurso = "#FFDE00";
private static string strColorHoy = "#3ECF00";
和这里的rowbounddata功能
and here's the rowbounddata function
protected void grdvEventosVendedor_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowIndex >= 0 && e.Row.Cells[11].Text == "Pendiente")
{
string strFecha = (e.Row.FindControl("lblFecha") as Label).Text;
int intYear = Convert.ToInt32(strFecha.Split('/')[2]);
int intMonth = Convert.ToInt32(strFecha.Split('/')[1]);
int intDay = Convert.ToInt32(strFecha.Split('/')[0]);
DateTime dtmFecha = new DateTime(intYear, intMonth, intDay);
if (dtmFecha < DateTime.Today)
{
e.Row.BackColor = Color.FromName(strColorUrgente);
}
else if (dtmFecha == DateTime.Today)
{
DateTime dtmHoraInicio = Convert.ToDateTime(e.Row.Cells[9].Text);
if (dtmHoraInicio > DateTime.Now)
{
e.Row.BackColor = Color.FromName(strColorHoy);
}
else
{
e.Row.BackColor = Color.FromName(strColorEnCurso);
}
}
}
}
每当我进入这个页面或我使用一个搜索引擎，我刷新了数据源的gridview的，当然，在的RowDataBound被触发......并最终某些行'颜色将改变...
Whenever I enter to this page or I use a search engine, I refresh the gridview with a datasource, and of course, the RowDataBound is triggered... and eventually some of the rows' colors will be changed...
您会发现，在GridView，在最后一列有一个名为按钮imgBtnVerMas ...
You'll notice that in the gridview, on the last column there's a button called imgBtnVerMas...
在pressed，它会触发下面的函数
When pressed, it triggers the following function
string strMensaje = "";
try
{
//Method that brings back data from a specific client (returns a datatable)
//intIdCliente was defined in the CommandArgument
DataTable dtDatosCliente = ConexionBD.GetInstanciaConexionBD().GetClienteEspecifico2(intIdCliente);
//Assigning to a string a message that needs info from the previous datatable
strMensaje += "DATOS DEL CLIENTE\\n\\nNombre:\\t" + dtDatosCliente.Rows[0]["Cliente"] + "\\nEmpresa: " + dtDatosCliente.Rows[0]["Empresa"];
}
catch
{
if (strMensaje == "")
{
strMensaje = "Hubo Un Error Al Traer Los Datos Del Cliente";
}
else
{
strMensaje += "\n\nERROR!!!!!!!";
}
}
ClientScript.RegisterStartupScript(this.GetType(), "Mensaje", "alert('" + strMensaje + "');", true);
此后，显示消息，但是，所有的行颜色dissapear ......我不知道......我怎能GridView的行的颜色，甚至是回发后...
Afterwards, the message is displayed, however, all of the rows colors dissapear... I was wondering... how can I keep the colors of the gridview's rows even after a postback...
感谢
推荐答案
您需要设置在prerender事件你的颜色，而不是的RowDataBound，这样设置的事件在GridView的
You need to set your colors on the event of onprerender and not on RowDataBound, so set the event on GridView
onprerender="gvMyLista_PreRender"
和code后面
protected void gvMyLista_PreRender(object sender, EventArgs e)
{
// loop your data, and fix your colors.
for (int i = 0; i < gvMyLista.Rows.Count; i++)
{
// get your data as...
// gvMyLista.Rows[i].Cells[2].Text
}
}
