.aspx页面

.cs页面
受保护 void Timer1_Tick（ object sender，EventArgs e）
{
Newmsgbind（）;
ModalPopupExtender3.Show（）;
}
public void Newmsgbind（）
{
SqlDataAdapter da_newmsg = new SqlDataAdapter（ 从Newmessage中选择Id，Clientname，Boardtype，Date，其中Readstatus =' + 0 + '，con）;
DataSet ds_newmsg = new DataSet（）;
da_newmsg.Fill（ds_newmsg）;
rptnewmsg.DataSource = ds_newmsg;
rptnewmsg.DataBind（）;
}
protected void lnkbtnmsg_Click（ object sender，EventArgs e）
{
string lnkbtnmsg =（sender as LinkButton）.CommandArgument;
con.Open（）;
SqlCommand cmdupdatemsg = new SqlCommand（ 更新Newmessage set Readstatus =' + 1 + '其中Id =' + lnkbtnmsg + ' ，con）;
cmdupdatemsg.ExecuteNonQuery（）;
con.Close（）;
}
解决方案
更改
< asp：repeater id = rptnewmsg runat = server xmlns：asp = ＃unknown >
到
< asp：repeater id = rptnewmsg <温泉n class =code-attribute> onitemcommand = rptNewMsg_ItemCommand runat = 服务器 >
和
< asp：linkbutton id = lnkbtnmsg runat = server causevalidation = true commandargument = <％ Eval（ Id ）％> validationgroup = hoo onclick < span class =code-keyword> = lnkbtnmsg_Click text = 未读 > < / asp：linkbutton >
to
< asp：linkbutton id = lnkbtnmsg runat = server causevalidation = true commandargument = <％ Eval（ Id）％> validationgroup < span class =code-keyword> = hoo commandname = 点击 text = 未读 > < < span class =code-leadattribute> / asp：linkbutton >
protected void rptNewMsg_ItemCommand（ object source，System.Web.UI.WebControls.RepeaterCommandEventArgs e）
{
if （e.CommandName == 点击）
{
string lnkbtnmsg = e.CommandArgument;
con.Open（）;
SqlCommand cmdupdatemsg = new SqlCommand（ 更新Newmessage set Readstatus =' + 1 + '其中Id =' + lnkbtnmsg + ' ，con）;
cmdupdatemsg.ExecuteNonQuery（）;
con.Close（）;
}
}
更改代码如下
< pre lang =HTML> < asp：linkbutton id = lnkbtnmsg runat = server causevalidation = true commandargument = <％ Eval（ Id）％> validationgroup = hoo < span class =code-attribute> onclick = lnkbtnmsg_Click text = 未读 xmlns：asp = ＃unknown > < / asp：linkbutton >
TO
< < span class =code-leadattribute> asp：linkbutton id= lnkbtnmsg runat = server causevalidation = true commandargument =' <％ #Eval（ Id）％>' validationgroup = hoo onclick = lnkbtnmsg_Cli ck text = 未读 xmlns：asp = ＃unknown > < / asp：linkbutton >
希望上述变更有效。

</asp:ModalPopupExtender>
</asp:ModalPopupExtender>
.cs page
protected void Timer1_Tick(object sender, EventArgs e)
{
Newmsgbind();
ModalPopupExtender3.Show();
}
public void Newmsgbind()
{
SqlDataAdapter da_newmsg = new SqlDataAdapter("select Id,Clientname,Boardtype ,Date from Newmessage where Readstatus ='" + 0 + "'", con);
DataSet ds_newmsg = new DataSet();
da_newmsg.Fill(ds_newmsg);
rptnewmsg.DataSource = ds_newmsg;
rptnewmsg.DataBind();
}
protected void lnkbtnmsg_Click(object sender, EventArgs e)
{
string lnkbtnmsg = (sender as LinkButton).CommandArgument;
con.Open();
SqlCommand cmdupdatemsg = new SqlCommand("update Newmessage set Readstatus ='" + 1 + "' where Id = '" + lnkbtnmsg + "'", con);
cmdupdatemsg.ExecuteNonQuery();
con.Close();
} 解决方案
change
<asp:repeater id="rptnewmsg" runat="server" xmlns:asp="#unknown">
to
<asp:repeater id="rptnewmsg" onitemcommand="rptNewMsg_ItemCommand" runat="server">
and
<asp:linkbutton id="lnkbtnmsg" runat="server" causesvalidation="true" commandargument="<%Eval("Id") %>" validationgroup="hoo" onclick="lnkbtnmsg_Click" text="unread"></asp:linkbutton>
to
<asp:linkbutton id="lnkbtnmsg" runat="server" causesvalidation="true" commandargument="<%Eval("Id") %>" validationgroup="hoo" commandname="Click" text="unread"></asp:linkbutton>
protected void rptNewMsg_ItemCommand(object source, System.Web.UI.WebControls.RepeaterCommandEventArgs e) { if(e.CommandName == "Click") { string lnkbtnmsg = e.CommandArgument; con.Open(); SqlCommand cmdupdatemsg = new SqlCommand("update Newmessage set Readstatus ='" + 1 + "' where Id = '" + lnkbtnmsg + "'", con); cmdupdatemsg.ExecuteNonQuery(); con.Close(); } }
Change the code as follow
<asp:linkbutton id="lnkbtnmsg" runat="server" causesvalidation="true" commandargument="<%Eval("Id") %>" validationgroup="hoo" onclick="lnkbtnmsg_Click" text="unread" xmlns:asp="#unknown"></asp:linkbutton>
TO
<asp:linkbutton id="lnkbtnmsg" runat="server" causesvalidation="true" commandargument='<%#Eval("Id")%>' validationgroup="hoo" onclick="lnkbtnmsg_Click" text="unread" xmlns:asp="#unknown"></asp:linkbutton>
Hope the above change works.
