GridView中的问题，排开ModalPopupExtender的onclick [英] ModalPopupExtender open onclick of GridView row problems

问题描述

（我使用Lukinha RS的解决方案，该行的onclick功能）

当我在GridView我收到了回发ModalPopupExtender打开之前在某一行上单击，我不想回发但是当你看到我使用的方法是原因。不幸的是我已经能够得到一个onClick应用到一个gridview排开MPE的唯一途径。

我的另一个问题是与MPE开放 - 我点击它只是重新加载使用相同的弹出PANAL开放所产生的页面弹出一个PANAL关闭按钮

 保护无效GridView1_RowDataBound（对象发件人，GridViewRowEventArgs E）
{
    GridViewRow排= e.Row;
    如果（row.DataItem == NULL）
    {
        返回;
    }    尝试
    {
        开关（e.Row.RowType）
        {
            案例DataControlRowType.Header：
                打破;            案例DataControlRowType.DataRow：
                e.Row.Attributes.Add（的onmouseover，this.style.cursor ='手'）;
                e.Row.Attributes.Add（onclick事件，Page.ClientScript.GetPostBackEventReference（GridView1，选择$+ e.Row.RowIndex.ToString（）））;
                打破;
        }
    }    抓住
    {
        返回;
    }
 

和这里是我的SelectedIndexChanged

 保护无效GridView1_SelectedIndexChanged（对象发件人，EventArgs的发送）
{
    GridViewRow行=（（GridView的）发件人）.SelectedRow;
    ModalPopupExtender MPE =（ModalPopupExtender）row.FindControl（ModalPopupExtender1）;
    mpe.Show（）;
}
 

解决方案

  

不幸的是我已经能够得到一个onClick的唯一途径
  适用于一个gridview行打开MPE

不正确。其实，你可以打开模式扩展没有回发。
更改的onclick 属性值如下：

  e.Row.Attributes.Add（onclick事件，的String.Format（JavaScript的：$找到（'{0}）显示（）;，ModalPopupExtender1.ClientID ））;
 

(I'm using Lukinha RS's solution to the row onclick functionality)

When I click on a row within the gridview I get a postback before the ModalPopupExtender opens, I dont want the postback however as you see the method I use is the cause. Unfortunatly it is the only way I have been able to get an onClick applied to a gridview row to open the MPE.

Another problem I have is with the MPE open - I click a 'close' button on the popup panal it simply reloads the page resulting with the same popup panal opening.

 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    GridViewRow row = e.Row;
    if (row.DataItem == null)
    {
        return;
    }

    try
    {
        switch (e.Row.RowType)
        {
            case DataControlRowType.Header:
                break;

            case DataControlRowType.DataRow:
                e.Row.Attributes.Add("onmouseover", "this.style.cursor='hand'");
                e.Row.Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(GridView1, "Select$" + e.Row.RowIndex.ToString()));
                break;
        }
    }

    catch
    {
        return;
    }

And here is my SelectedIndexChanged

    protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
    GridViewRow row = ((GridView)sender).SelectedRow;
    ModalPopupExtender mpe = (ModalPopupExtender)row.FindControl("ModalPopupExtender1");
    mpe.Show();
}

解决方案

Incorrectly. Actually, you CAN open modal extender without postback. Change onclick attribute value as below:

e.Row.Attributes.Add("onclick", String.Format("javascript:$find('{0}').show();", ModalPopupExtender1.ClientID));
