后台弹出删除框根据结果选择执行

在使用服务器端控件的情况下，不能在页面上直接使用在js中用confirm进行删除判断

操作方式：在页面放置两个删除按钮控件，一个是可见的，用于触发后台的confirm判断，一个是隐藏的真正删除按钮，

我们还需要一个隐藏控件，用于保存confirm的选择结果

源码如下：

aspx界面：

<cc2:DcjetButton UseSubmitBehavior="false" OnClick="btnDelete_Click" Text="删 除" runat="server"
ID="btnDelete" />

<!--隐藏控件存值-->
<cc2:DcjetButton UseSubmitBehavior="false" OnClick="btnHiddenDelete_Click" Width="0px"
Height="0px" ID="btnHiddenDelete" runat="server" />
<asp:HiddenField ID="hidField" runat="server" />
<asp:HiddenField ID="hidFieldOid" runat="server" />

后台：

/// <summary>
/// 获取选中行的OID
/// </summary>
/// <returns></returns>
private string GetSelectedOid()
{
string strOid = string.Empty;
for (int i = 0; i < this.gvInfo.Rows.Count; i++)
{
CheckBox chk = (CheckBox)this.gvInfo.Rows[i].FindControl("chkSelected");
if (chk.Checked == true)
{
strOid += chk.ToolTip + "|";
}
}
if (!string.IsNullOrEmpty(strOid))
{
strOid = strOid.Substring(0, strOid.Length - 1);
}
return strOid;
}
/// <summary>
/// 删除弹框
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void btnDelete_Click(object sender, EventArgs e)
{
strOid = GetSelectedOid();
this.hidFieldOid.Value = strOid;
if (string.IsNullOrEmpty(strOid))
{
ScriptManager.RegisterStartupScript(this, this.GetType(), "", "alert('请选择您要删除的[" + this.PageReportName + "]！');", true);
return;
}
string js = string.Format("document.getElementById('{0}').value=confirm('确定要删除已选的记录?');document.getElementById('{1}').click();", this.hidField.ClientID, this.btnHiddenDelete.ClientID);
ClientScript.RegisterStartupScript(GetType(), "confirm", js, true);
}

/// <summary>
/// 真正的删除操作
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void btnHiddenDelete_Click(object sender, EventArgs e)
{
if (bool.Parse(this.hidField.Value) == true)
{
strOid = this.hidFieldOid.Value;
HbViewCostManageDao hbcDao = new HbViewCostManageDao(DataConstCm.PARA_PLAT_DB_TYPE, objPageParaMessage.CompanyDBConn);
hbcDao.Delete(strOid);
DataLoadInfo(GetModelInfo(), strSorting);
}
}
