可点击的gridview行 [英] Clickable gridview rows

问题描述

我正在使用gridview .i需要使gridview行可点击，因为在选定的索引更改事件我需要执行数据库操作。所以我使用以下代码。

  protected   void  GridView1_RowDataBound（ object  sender，GridViewRowEventArgs e）
 {
  if （e.Row.RowType == DataControlRowType.DataRow）
 {
  if （e.Row.RowType == DataControlRowType.DataRow）
 {
  //  < span class =code-comment>获取gridview中按钮字段的引用。 
 LinkBut​​ton _singleClickButton =（LinkBut​​ton）e.Row.Cells [ 0 ].Controls [ 0 ]; 
  string  _jsSingle = ClientScript.GetPostBackClientHyperlink（_singleClickButton， 选择$ + e.Row.RowIndex）; 
 e.Row.Style [  cursor] =   hand; 
 e.Row.Attributes [  onclick] = _jsSingle; 
} 
} 
} 
 受保护  void  GridView1_SelectedIndexChanged （ object  sender，EventArgs e）
 {
 GridViewRow selectedRow = GridView1.SelectedRow; 
 lblSelectedRow.Text = GridView1.SelectedIndex.ToString（）; 
 lblName.Text = selectedRow.Cells [ 2 ]。文字; 
 lblEmpId.Text = selectedRow.Cells [ 3 ]。文字; 
} 
 
 受保护 覆盖  void  Render（HtmlTextWriter writer）
 {
  foreach （GridViewRow row  in  GridView1.Rows）
 {
  if （row.RowType == DataControlRowType.DataRow）
 {
 ClientScript.RegisterForEventValidation（（（LinkBut​​ton）row.Cells [ 0 ]。控件[ 0 ]） .UniqueID， 选择$ + row.RowIndex）; 
} 
} 
  base  .Render（writer）; 
} 

我能够点击该行，但我无法控制所选索引更改事件，即控件不会执行此事件我获得此代码的链接在那里工作正常。唯一的区别是我的页面包含附加到它的母版页。我也没有使用更新面板。我错过了什么。什么都出错了。

帮我..

帮助我..

请参阅我的提示 - 没有选择按钮的Fire GridView SelectedIndexChanged事件 [ ^ ]。

试试这个。调试时会转到 SelectedIndexChanged 事件。





问题用你的代码



我认为问题在于以下代码...

  string  _jsSingle = ClientScript.GetPostBackClientHyperlink（_singleClickButton， 选择

i m using gridview .i need to make gridview rows clickable since on selected index changed event i need to perform database operations.So i m using the following code.

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            // Get reference to button field in the gridview.
            LinkButton _singleClickButton = (LinkButton)e.Row.Cells[0].Controls[0];
            string _jsSingle = ClientScript.GetPostBackClientHyperlink(_singleClickButton, "Select$" + e.Row.RowIndex);
            e.Row.Style["cursor"] = "hand";
            e.Row.Attributes["onclick"] = _jsSingle;
        }
    }
}
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
    GridViewRow selectedRow = GridView1.SelectedRow;
    lblSelectedRow.Text = GridView1.SelectedIndex.ToString();
    lblName.Text = selectedRow.Cells[2].Text;
    lblEmpId.Text = selectedRow.Cells[3].Text;
}

protected override void Render(HtmlTextWriter writer)
{
    foreach (GridViewRow row in GridView1.Rows)
    {
        if (row.RowType == DataControlRowType.DataRow)
        {
            ClientScript.RegisterForEventValidation(((LinkButton)row.Cells[0].Controls[0]).UniqueID, "Select$" + row.RowIndex);
        }
    }
    base.Render(writer);
}

I m able to click the row but i am not able to get control over the selected index changed event i.e. the control doesnt go to this event while debugging.The link from which i got this code works fine there.the only difference is that my page contains master page attached to it.I m not using update panel too.Am i missing something.whats going wrong.
help me..

Refer my Tip - Fire GridView SelectedIndexChanged Event without Select Button[^].
Try this. It goes to the SelectedIndexChanged Event while debugging.


Problem with your code

string _jsSingle = ClientScript.GetPostBackClientHyperlink(_singleClickButton, "Select
