在Postback后取消选中CheckBox

问题描述

我在用户控件的ItemTemplate（gridview）中使用复选框。我在CheckedChanged事件中写了一些代码。它正在运行。完成活动后，我的页面加载时取消选中复选框。

Hi,
I am using check box in ItemTemplate(gridview) in User Control. I wrote some code in CheckedChanged event. It is Running. after completing the event my page is loading with uncheck checkbox.

<asp:TemplateField ItemStyle-Width="4%">
                                        <ItemTemplate>
                                            <asp:CheckBox Width="10%" ID="chkDocumentName" runat="server" OnCheckedChanged="chkDocumentName_CheckedChanged" AutoPostBack="true"/>
                                        </ItemTemplate>
                                        <ItemStyle Width="3%" />
                                    </asp:TemplateField>

protected void chkDocumentName_CheckedChanged(object sender, EventArgs e)
    {
        for (int i = 0; i < gvDocumentTemplatestatus.Rows.Count; i++)
        {
            CheckBox chkbox = (CheckBox)gvDocumentTemplatestatus.Rows[i].FindControl("chkDocumentName");
            if (chkbox.Checked == true)
            {
                Label lblTemplateId = (Label)gvDocumentTemplatestatus.Rows[i].FindControl("lblTempID");
                Label lblDocumentNumberID = (Label)gvDocumentTemplatestatus.Rows[i].FindControl("lblDocumentNumberID");
                 Label lblTemplateName = (Label)gvDocumentTemplatestatus.Rows[i].FindControl("lblTemplateName");
                 Session["rownumber"] = i.ToString();
                Session["TempID"] = lblTemplateId.Text;

            }
            else
            {
                if (Session["rownumber"] != null)
                {
                    if (Convert.ToInt32(Session["rownumber"].ToString()) == i)
                    {
                        strcolumnnumber = "0";
                        Session["SubJobID"] = strcolumnnumber;
                    }
                }
            }
        }
    }

这是我的代码在回复后我的复选框未经检查。







如果有人知道这个告诉我。

推荐答案

<updatepanel>
<contenttemplate>
<asp:checkbox width="10%" id="chkDocumentName" runat="server" oncheckedchanged="chkDocumentName_CheckedChanged" autopostback="true" xmlns:asp="#unknown" />
</contenttemplate>
</updatepanel>

如果仍然无法正常工作

然后使用异步回发触发器与此更新面板

if still not working
then use asynchronous postback trigger with this updatepanel
