后台弹出删除框根据结果选择执行【转】

转自http://blog.csdn.net/yiqijinbu/article/details/8432099 csdn上的博客被封了，进不去，博客园中留着备份以后会有用的

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：

[csharp] view plain copy

print?

<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：

[csharp] view plain copy

print?

/// <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);

}
