[英]Want to show data for a specific row in the gridview when that row's buttonfield is clicked
我看到了與此主題類似的帖子,但無法解決我的問題。 我正在使用Access數據庫。 因此,此頁面將從數據庫中加載數據,但是在單擊該特定行的按鈕之前,它將不會顯示任何數據。 目前,它正在顯示所有數據。 這是我的代碼,請給我一些建議。
<columns>
<asp:buttonfield buttontype="Button"
commandname="Select"
headertext="Select Customer"
text="Select"/>
<asp:boundfield datafield="Customer ID" readonly="true" headertext="Customer ID"/>
<asp:TemplateField HeaderText="First Name" AccessibleHeaderText="FirstName">
<ItemTemplate>
<asp:Label ID ="txtEmployeeName" runat ="server" Text='<%# Eval("firstName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</columns>
public partial class DisplayCustomer : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
DataLayer.DataConnector dat = new DataLayer.DataConnector(@"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Users\Ovich\Documents\Visual Studio 2013\WebSites\WebSite3\App_Data\Customer.accdb");
DataTable dt = dat.DataSelect("SELECT* from Customer");
GridView1.DataSource = dt;
GridView1.DataBind();
}
public void CustomersGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
{
// If multiple ButtonField column fields are used, use the
// CommandName property to determine which button was clicked.
if (e.CommandName == "Select")
{
// Convert the row index stored in the CommandArgument
// property to an Integer.
int index = Convert.ToInt32(e.CommandArgument);
// Get the last name of the selected author from the appropriate
// cell in the GridView control.
GridViewRow selectedRow = GridView1.Rows[index];
}
}
}
如果您可以像使用“客戶名稱”一樣用模板字段替換“ Customer Id
綁定字段”,那么它將非常簡單:-
<columns>
<asp:Buttonfield buttontype="Button" commandname="Select" headertext="Select Customer"
text="Select"/>
<asp:TemplateField HeaderText="Employee Id" AccessibleHeaderText="FirstName">
<ItemTemplate>
<asp:Label ID ="lblEmployeeId" runat ="server"
Text='<%# Eval("EmployeeId") %>' Visible="false"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="First Name" AccessibleHeaderText="FirstName">
<ItemTemplate>
<asp:Label ID ="txtEmployeeName" runat ="server"
Text='<%# Eval("firstName") %>' Visible="false"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</columns>
您可以像我一樣簡單地將控件的可見性設置為false
,並在RowCommand
事件中單擊按鈕時將其顯示:
protected void CustomersGridView_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Select")
{
int index = Convert.ToInt32(e.CommandArgument);
((Label)grdCustomer.Rows[index].FindControl("lblEmployeeId")).Visible = true;
((Label)grdCustomer.Rows[index].FindControl("txtEmployeeName")).Visible = true;
}
}
使用BoundControls
您將必須顯式隱藏數據和標頭,這會使事情變得復雜。
