Rowdata绑定方法未被执行。 [英] Rowdata bound method is not being executed.

问题描述

protected void gvIssuedetails_RowDataBound（object sender，GridViewRowEventArgs e）

{

if（e.Row.RowType == DataControlRowType.DataRow）

{

SqlConnection con = new SqlConnection（ConfigurationManager.ConnectionStrings [IssueTracker] .ConnectionString）;

DropDownList ddlupdatestatus =（DropDownList）e.Row.FindControl（ddlupdatestatus ）;

标签lblupdatestatus =（标签）e.Row.FindControl（lblupdatestatus）;

if（ddlupdatestatus！= null）

{

SqlCommand cmdselect = new SqlCommand（）;

SqlDataAdapter sda = new SqlDataAdapter（cmdselect）;

cmdselect.CommandType = CommandType.StoredProcedure ;

cmdselect.CommandText =usp_getstatusclient;

cmdselect.Connectio n = con;

DataTable dt = new DataTable（）;

sda.Fill（dt）;

if（dt.Rows.Count > 0）

{

ddlupdatestatus.DataSource = dt;

ddlupdatestatus.DataTextField =StatusName;

ddlupdatestatus .DataValueField =StatusId;

ddlupdatestatus.DataBind（）;

ddlupdatestatus.Items.Insert（0，new ListItem（ - SELECT--，0 ））;

}

else

{

ScriptManager.RegisterStartupScript（this，this.GetType（） ，script，alert（''Source Not Available''）;，true）;

}

ddlupdatestatus.SelectedValue = lblupdatestatus.Text;

}

}

}





当我放置它不会转到这个方法的断点，它不会执行，tha t是为什么我无法在网格项目中绑定ddl。



请建议我解决一些问题。

<在aspx页面中的blockquote> OnRowDataBound =gvIssuedetails_RowDataBound

protected void gvIssuedetails_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["IssueTracker"].ConnectionString);
DropDownList ddlupdatestatus = (DropDownList)e.Row.FindControl("ddlupdatestatus");

if (ddlupdatestatus != null)

SqlCommand cmdselect = new SqlCommand();
SqlDataAdapter sda = new SqlDataAdapter(cmdselect);
cmdselect.CommandType = CommandType.StoredProcedure;
cmdselect.CommandText = "usp_getstatusclient";
cmdselect.Connection = con;
DataTable dt = new DataTable();
sda.Fill(dt);
if (dt.Rows.Count > 0)
{
ddlupdatestatus.DataSource = dt;
ddlupdatestatus.DataTextField = "StatusName";
ddlupdatestatus.DataValueField = "StatusId";
ddlupdatestatus.DataBind();
ddlupdatestatus.Items.Insert(0, new ListItem("--SELECT--", "0"));
}
else
{
ScriptManager.RegisterStartupScript(this, this.GetType(), "script", "alert(''Source Not Available'');", true);
}
ddlupdatestatus.SelectedValue = lblupdatestatus.Text;
}
}
}


when I place the breakpoint it doesnot goes to this method and it is not executed , that is why i am unable to bind the ddl in griditem.

Please suggest me some solution.
