对另一列的超链接引用DevExpress Gridview ASP.Net Webform [英] Hyperlink Reference to another column DevExpress Gridview ASP.Net Webform

问题描述

我正在使用for循环，使用VB.Net将列添加到DevExpress ASP.Net WebForms GridView中。我能够获得一个超链接来引用相同的列值：

I'm using a for loop to add columns to the DevExpress ASP.Net WebForms GridView using VB.Net. I was able to get a hyperlink to reference the same column value:

Dim newColumn As New DevExpress.Web.GridViewDataHyperLinkColumn
newColumn.PropertiesHyperLinkEdit.NavigateUrlFormatString = "TrendView.aspx?CurrentID={0}"

我需要以编程方式将超链接设置为另一列的值...即，第三列需要具有引用同一行中列1值的超链接。您如何在运行时使用VB或C＃访问该行的另一列？

I need to programmatically set the hyperlink to another column's value... i.e. column three needs to have a hyperlink that references the column 1 value in the same row. How do you access another column in that row using VB or C# during runtime?

将填充的网格逻辑更改为

change your populate grid logic as

ASPX：

<dx:ASPxGridView ID="ASPxGridView1" runat="server"></dx:ASPxGridView>

CS

protected void Page_Init(object sender, EventArgs e)
{
     ASPxGridView1.KeyFieldName = "ID";
     ASPxGridView1.DataSource = GetData();
     if (!IsPostBack && !IsCallback)
     {
         PopulateColumns();
         ASPxGridView1.DataBind();
     }
}

public DataTable GetData()
{
    DataTable Table = new DataTable();
    Table.Columns.Add("ID", typeof(int));
    Table.Columns.Add("ItemName", typeof(string));
    Table.Columns.Add("ItemValue", typeof(string));
    Table.Rows.Add(1, "A","AA");
    Table.Rows.Add(2, "B","BB");
    return Table;
}

public void PopulateColumns()
{
    GridViewDataTextColumn colID = new GridViewDataTextColumn();
    colID.FieldName = "ID";
    ASPxGridView1.Columns.Add(colID);

    GridViewDataTextColumn srk = new GridViewDataTextColumn();
    srk.FieldName = "ItemValue";
    ASPxGridView1.Columns.Add(srk);

    GridViewDataHyperLinkColumn colItemName = new GridViewDataHyperLinkColumn();
    colItemName.FieldName = "ItemValue";
    colItemName.PropertiesHyperLinkEdit.NavigateUrlFormatString = "~/details.aspx?Device={0}";
    colItemName.PropertiesHyperLinkEdit.TextFormatString = "{0}";
    colItemName.PropertiesHyperLinkEdit.TextField = "ItemName";
    ASPxGridView1.Columns.Add(colItemName);
}

此处列itemName将itemValue称为url字符串参数

here column itemName refer to itemValue as url string params
