生成复选框列在网格视图新列 [英] generating new column in grid view for checkbox column

问题描述

我使用数据表作为网格视图数据源

i am using datatable as data source for grid view

     DataTable table = new DataTable();
    table.Columns.Add("Dosage", typeof(int));
    table.Columns.Add("Drug", typeof(string));
    table.Columns.Add("Patient", typeof(string));
    table.Columns.Add("Select",typeof(bool));


    //
    // Here we add five DataRows.
    //
    table.Rows.Add(25, "Indocin", "David");
    table.Rows.Add(50, "Enebrel", "Sam");
    table.Rows.Add(10, "Hydralazine", "Christoff");
    table.Rows.Add(21, "Combivent", "Janet");
    table.Rows.Add(100, "Dilantin", "Melanie");


    GridView2.DataSource = table;


    GridView2.DataBind();   

在页面加载
，我想在网格创建新列添加单选按钮

at page load and i want to create new column in grid to add radio button

其实我想在数据库提交的行值选中的复选框。

actually i want to submit row values for selected check boxes in database..

推荐答案

如果您希望将新列添加到 GridView控件你应该把它添加到它的数据源。无论是从数据库，或者选择另一列如果您使用的内存数据表作为这里 - 通过添加另一个的DataColumn 。但我相信，你已经添加列（选择）。

If you want to add a new column to the GridView you should add it to it's DataSource. Either by selecting another column from the database or, if you use an in-memory DataTable as here- by adding another DataColumn. But i assume that you already have added the column(Select).

然后用模板列添加单选和eval /其绑定到列。

Then use a TemplateField to add the RadioButton and eval/bind it to the column.

<asp:GridView ID="GridView2" runat="server" AutoGenerateColumns="False" OnRowDataBound="GridView2_RowDataBound" >
         <Columns>
            <asp:TemplateField HeaderText="Select">
                  <ItemTemplate>
                     <asp:RadioButton ID="rbSelect"   runat="server" />
                  </ItemTemplate>
            </asp:TemplateField>

您可以使用的RowDataBound 根据数据源检查：

You can use RowDataBound to check it according to the datasource:

protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        var rbSelect = (RadioButton)e.Row.FindControl("rbSelect");
        var row = ((DataRowView)e.Row.DataItem).Row;
        rbSelect.Checked = row.Field<bool>("Select");
    }
}
