如何检查是否从GridView中选择了任何行
本文关键字:GridView 选择 任何行 是否 何检查 检查 | 更新日期: 2023-09-27 18:00:43
我在aspx页面中有一个网格视图:
<asp:GridView ID="gdvMainList" runat="server" CssClass="Grid1" SkinID="PagedGridView"
AutoGenerateColumns="false" OnRowDataBound="gdvMainList_RowDataBound"
DataSourceId="dtsConsumers" Visible="false" DataKeyNames="Id">
<Columns>
<asp:CommandField SelectText="Select" ShowSelectButton="true" ItemStyle-CssClass="HideButton"
HeaderStyle-CssClass="HideButton">
<HeaderStyle CssClass="HideButton" />
<ItemStyle CssClass="HideButton" />
</asp:CommandField>
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<span>
<%# Pc.PrecisionCare2.PL.Common.Utility.GetFullName("", Eval("LastName"), Eval("FirstName"), Eval("MiddleInit")) %></span>
</ItemTemplate>
<ItemStyle Width="200px" />
</asp:TemplateField>
<asp:BoundField DataField="Status" HeaderText="Status" SortExpression="Status"></asp:BoundField>
</Columns>
<SelectedRowStyle CssClass="SelectedItem" BackColor="#c9e0ee" />
<EmptyDataTemplate>
<div class="divEmptyGrid">
--- No Consumer Exists ---
</div>
</EmptyDataTemplate>
</asp:GridView>
rowDataBound
方法为:
protected void gdvMainList_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.gdvMainList, "Select$" + e.Row.RowIndex);
}
}
我有一个确定按钮,当它被点击时,我会从页面收集数据。我想在单击"确定"按钮时检查是否有从网格视图中选择的行。
我怎样才能做到这一点?
您可以检查如下。。。
if (GridView1.SelectedValue != null)
{
//Row is Selected
}
您可以尝试以下操作:
If GridView1.SelectedRows.Count > 0 Then
' yourcode here - a row is selected
Else
' yourcode here - NO row is selected
End If
更好的方法:
if(GridView1.SelectedIndex < 0)
{ its -1 and no row is selected.}
else
{its >= 0 and a row is selected}
如果选择的值是CCD_ 3,则对CCD_。
您也可以像这样检查
if(GridView.SelectedIndex >= 0)
{
string result = "Selected";
}
else
{
string result = "Not Selected";
}
