Question

gridView编辑状态下某一列加入按钮

我想在gridView的编辑状态下在某一列加入一个Button，不知道具体如何做....请各位大侠指点
大家没明白我的意思吗？

Answer 1

要将gridview的某一列加入按钮方法：
取值方法如下：
string id = (GridView1.Rows[e.RowIndex].FindControl("TextBox2") as TextBox).Text;
将gridview的列转换成模板以后，在VS里面查看源代码，看你的gridview，结果就出现了。

Answer 2

不太明白，如果是覆盖在gridview上的话，可以用贞布局，放一个Button，先设为不可见，在需要加入是在设为可见，如果不是覆盖，而是在gridview 下面就不用贞布局，也是可见不可见的设置就可以解决了，不知道你是不是这个意思。

Answer 3

你想用那个button做提交按钮么？？
gridView在编辑状态下会有一个确定按钮，为什么你还要单放button

追问

我有一列的数据是存入数据库图片的路径，我想在编辑状态下的时候再这一列上添加一个浏览的button,然后可以通过这个按钮来更改图片的路径。 具体和 fileUpLoad相似。

前端：

onrowediting="GridView1_RowEditing"
onrowcancelingedit="GridView1_RowCancelingEdit"
onrowdatabound="GridView1_RowDataBound" onrowupdating="GridView1_RowUpdating" >
<Columns>
<asp:BoundField DataField="ID" HeaderText="ID" />
<asp:BoundField DataField="Name" HeaderText="Name" />
<asp:TemplateField HeaderText="Photo">
<EditItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# Bind("Photo") %>' />
<asp:FileUpload ID="FileUpload1" runat="server" />
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="lblPhoto" runat="server" Text='<%# Bind("Photo") %>'></asp:Label>

</asp:TemplateField>
<asp:TemplateField HeaderText="编辑">

</asp:TemplateField>
</Columns>
</asp:GridView>
后端：
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindData();
}
}

private void BindData()
{
DataTable dt = new DataTable();
dt.Columns.Add("ID", typeof(string));
dt.Columns.Add("Name", typeof(string));
dt.Columns.Add("Photo", typeof(string));

DataRow dr = dt.NewRow();

dt.Rows.Add(dr);
dt.Rows.Add(dr1);

GridView1.DataSource = dt;
GridView1.DataBind();

}

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

}
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
//更新数据的事在这里做
}
protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{

BindData();
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow && ((e.Row.RowState & DataControlRowState.Edit) > 0))
{
FileUpload fu = (FileUpload)e.Row.FindControl("FileUpload1");
Image image = (Image)e.Row.FindControl("Image1");
fu.Attributes.Add("onpropertychange", "javascript:document.getElementById('" + image.ClientID + "').src=document.getElementById('" + fu.ClientID + "').value");

}
}
