问题描述

Quote：

我有一个网格，其中我有7列，其中所有复选框都被禁用。如何禁用删除按钮？



如果取消SO行项目列中的所有复选框都被禁用，则应禁用DEL按钮。

I have a grid in which I have 7 columns where all the checkboxes are disabled. How do I disable the delete button?

if all the checkboxes in the Cancel SO Line Item column are disabled then the DEL button should be disabled.

.Aspx文件

.Aspx File

<asp:TemplateField HeaderText="Cancel SO Line Item">
        <ItemTemplate>
        <asp:checkbox ID="cbSOCan" runat="server" ViewStateMode="Enabled" EnableViewState="true"></asp:checkbox>
         </ItemTemplate>

     <asp:LinkButton CssClass="btn btn-primary" ID="btnCancelItem" runat="server" CausesValidation="False"OnClientClick="return Confirmationbox();"> Cancel 
Item</asp:LinkButton>
 <asp:HiddenField id="hdnval" value=0 runat="server"/>

bool oneCheckBoxIsEnabled = false;
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
    {
CheckBox cb = e.Row.FindControl("CheckBox1") as CheckBox;
        if (cb.Enabled == true)
        {
            oneCheckBoxIsEnabled = true;
        }
    }
    else if (e.Row.RowType == DataControlRowType.Footer)
    {
        //use the footer row to enable or disable the button
        DeleteButton.Enabled = oneCheckBoxIsEnabled;
    }
}
