Question

我有使用itemTemplate的gridview包含一个在onCheckChanged触发的复选框。我想要捕获gridview所在的gridview列和行。

我该怎么做？

public void PM_chkbx_Chacked_Changed(object sender, EventArgs e)
{
     //What to write here?
}

Answer 1

我在gridview中使用了 datakeys ，并且能够获取行和特定列。这里gridview id是 grdrequestlist 。

public void PM_chkbx_Chacked_CheckedChanged(object sender, EventArgs e)
{
//here you can get row on whcih you checkbox chnged event called

GridViewRow Row = ((GridViewRow)((Control)sender).Parent.Parent);
string requestid = grdrequestlist.DataKeys[Row.RowIndex].Value.ToString();
string cellvalue=Row.Cells[1].Text;
}

此gridview的.aspx页面设计，您可以在列部分添加列。

<asp:GridView ID="grdrequestlist" runat="server" DataKeyNames="RequestId" >
<Columns>
 <asp:TemplateField HeaderText="Actions" >
                 <ItemTemplate>
 <asp:CheckBox ID="PM_chkbx_Chacked" AutoPostBack="true" runat="server" oncheckedchanged="PM_chkbx_Chacked_CheckedChanged" />
                 </ItemTemplate>
                </asp:TemplateField>
                    </Columns>
</asp:GridView>

希望这会对你有所帮助。

我找到了解决方案：

public void PM_chkbx_Chacked_Changed(object sender, EventArgs e)
    {
        GridViewRow gvr = ((GridViewRow)((Control)sender).Parent.Parent);
        int index_row = gvr.RowIndex;
        string role_name = gv_permissions_management.DataKeys[index_row].Value.ToString();
        string fileld_name = ((DataControlFieldCell)((Control)sender).Parent).ContainingField.HeaderText;
        ((DataControlFieldCell)((Control)sender).Parent).BackColor = Color.Red; //Color the Cell

     }

从itemtemplate复选框事件中获取gridview列和行
