获取按钮点击行的DataKeyNames [英] Getting DataKeyNames for row on button click

问题描述

我在每行都有一个带有按钮的gridview：

这些按钮位于模板字段中：

 < asp：GridView ID =storyGridViewrunat =serverAllowSorting =TrueAutoGenerateColumns =False
 BackColor =#DEBA84BorderColor =＃DEBA84BorderStyle =None BorderWidth =1pxCellPadding =3
 CellSpacing =2DataKeyNames =PK_NonScrumStoryDataSourceID =SqlDataSource1> 
 ... 
< asp：TemplateField HeaderText =Actions> 
< ItemTemplate> 
< asp：Button ID =viewHoursButtonrunat =serverText =View HoursOnClick =viewHoursButton_OnClick/> 
< asp：Button ID =addHoursButtonrunat =serverText =Add HoursOnClick =addHoursButton_OnClick/> 
< asp：Button ID =editButtonrunat =serverText =EditOnClick =editButton_OnClick/> 
< asp：Button ID =deleteButtonrunat =serverText =DeleteOnClick =deleteButton_OnClick/> 
< / ItemTemplate> 
< / asp：TemplateField> 
  

如何在点击时获取数据键名称？

  protected void viewHoursButton_OnClick（object sender，EventArgs e）
 {
 //获得点击行的PK_NonScrumStory 
} 
  

解决方案

我发现：

  protected void viewHoursButton_OnClick（object sender，EventArgs e）
 {
 Button btn = sender as Button; 
 GridViewRow row = btn.NamingContainer as GridViewRow; 
 string pk = storyGridView.DataKeys [row.RowIndex] .Values [0] .ToString（）; 
 System.Diagnostics.Debug.WriteLine（pk）; 
} 
  

I have a gridview with buttons in each row:

The buttons are in a templatefield:

<asp:GridView ID="storyGridView" runat="server" AllowSorting="True" AutoGenerateColumns="False" 
      BackColor="#DEBA84" BorderColor="#DEBA84" BorderStyle="None" BorderWidth="1px" CellPadding="3"    
      CellSpacing="2" DataKeyNames="PK_NonScrumStory" DataSourceID="SqlDataSource1">
...
        <asp:TemplateField HeaderText="Actions">
            <ItemTemplate>
                <asp:Button ID="viewHoursButton" runat="server" Text="View Hours" OnClick="viewHoursButton_OnClick" />
                <asp:Button ID="addHoursButton" runat="server" Text="Add Hours" OnClick="addHoursButton_OnClick" />
                <asp:Button ID="editButton" runat="server" Text="Edit" OnClick="editButton_OnClick" />
                <asp:Button ID="deleteButton" runat="server" Text="Delete" OnClick="deleteButton_OnClick" />
            </ItemTemplate>
        </asp:TemplateField>

How do I get the data key name on click?

protected void viewHoursButton_OnClick(object sender, EventArgs e)
{
    //get PK_NonScrumStory for clicked row
}

解决方案

I figured it out:

protected void viewHoursButton_OnClick(object sender, EventArgs e)
{
    Button btn = sender as Button;
    GridViewRow row = btn.NamingContainer as GridViewRow;
    string pk = storyGridView.DataKeys[row.RowIndex].Values[0].ToString();
    System.Diagnostics.Debug.WriteLine(pk);
}
