gridview的编辑模式编程 [英] gridview edit mode programatically

问题描述

我有一个基本的GridView到我从背后code从SQL存储过程绑定的数据。

I have a basic gridview to which I am binding the data from the code behind from a SQL stored procedure.

<asp:GridView ID="gvCheckResults" runat="server" OnRowDataBound="gvCheckResults_RowDataBound" RowStyle-CssClass="gridViewRow" CssClass="gridView"
AlternatingRowStyle-CssClass="gridViewAlternatingRow" HeaderStyle-CssClass="gridViewHeader">
</asp:GridView> 

数据绑定：

gvCheckResults.DataSource = dataContext.GetResults(Name, Address);
gvCheckResults.DataBind();

if (!IsPostBack)
    {
        //Add Edit column.
        CommandField cField = new CommandField();
        cField.EditText = "Edit";
        cField.ShowEditButton = true;
        gvCheckResults.Columns.Insert(0, cField);
    }

我如何编程方式添加编辑按钮，每个结果行？
我知道该怎么做时，数据源对象是设置在aspx页面，但从来没有编程这样做。

How can I programmatically add Edit button to each result row? I know how to do it when the datasource object is setup in the aspx page, but never done it programmatically.

推荐答案

尝试像这样

      <asp:TemplateField HeaderText="Edit>
 <ItemTemplate>
        <asp:LinkButton Id="lnkEdit" runat="server" CommandName="Edit" Text="Edit"/>
</ItemTemplate>
<EditItemTemplate>
            <asp:LinkButton Id="lnkEdit" runat="server" CommandName="Update" Text="Update"/>
            <asp:LinkButton Id="LinkButton1" runat="server" CommandName="Cancel" Text="Cancel"/>
            </EditItemTemplate>
        </asp:TemplateField>

OnRowEditEvent（）设置gridview的编辑索引e.newrowindex并再次绑定像这样。

OnRowEditEvent() set the gridview edit index to e.newrowindex and bind it again like this.

    protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
    {
        GridView1.EditIndex = e.NewEditIndex;
        GridView1.DataBind();

    }
    protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
//Write code TO UPDATE YOUR DATABESE THEN WRITE BELOW CODE IN LAST
// To Find Text of TextBox to get updated value....you get it in string like this.
//string strName = ((TextBox)grdview1.Rows[e.RowIndex].Cells[YourColumnIndexInWhichTexBoxAppear].Controls[0]).Text;
    GridView1.EditIndex = -1;
            GridView1.DataBind();
        }
        protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
        {
            GridView1.EditIndex = -1;
            GridView1.DataBind();
        }
