如何在不使用处理程序类的情况下在gridview模板字段内显示图像？ [英] How to display image inside gridview template field without using handler class?

问题描述

我想在gridview的模板字段中显示图像。我想知道如何传递Image控件的Image url。
这就是我所做的 -
ASPX页面：

I want to display image within template field of the gridview. I want to know how can I pass Image url for the Image control. This is what I am doing- ASPX Page:

<asp:GridView ID="GridView1" runat="server" Width="1000px" CellPadding="4" 
                    ForeColor="#333333" GridLines="None" AutoGenerateColumns="False">
                    <AlternatingRowStyle BackColor="White" ForeColor="#284775" />
                    <Columns>
                        <asp:TemplateField>
                            <ItemTemplate>
                                <asp:Image ID="Image1" runat="server" Height="122px" 
                                    ImageUrl="" Width="148px" />
                                <br />
                            </ItemTemplate>
                            <ItemStyle HorizontalAlign="Left" VerticalAlign="Top" Width="300px" />
                        </asp:TemplateField></asp:GridView>

.CS代码：

public void show()
{
    try
    {
        dt = g1.return_dt("select * from tbl_item_post where Ref_No is not null order by company");
        if (dt.Rows.Count > 0)
        {
            pic1 = Convert.ToString(dt.Rows[0]["image_url"]);
            adsource = new PagedDataSource();
            adsource.DataSource = dt.DefaultView;
            adsource.PageSize = 10;
            GridView1.DataSource = adsource;
            GridView1.DataBind();
        }
        else
        {
            GridView1.DataSource = null;
            GridView1.DataBind();
        }
    }
    catch (Exception ex)
    {
        ex.ToString();
    }
}

请指导我如何做到这一点。

Please Guide me how to do this.

推荐答案

您可以像这样直接绑定gridview中的图片url

You can directly bind the image url in the gridview like this

<asp:Image ID="Image1" runat="server" Height="122px" ImageUrl='<%# Eval("image_url","~/Images/{0}") %>' Width="148px" />

您可以随时创建正确的网址，具体取决于您在数据库中保存的值图片。

You can always able to create the correct url depending upon what values are you saving in the database for the image.
