如何使用datatable作为数据源向gridview动态添加链接按钮

Question

在这里，我完成了codeehind中的每一件事。我动态地创建了一个网格视图。

DataTable dt=null
dt=loadDynamicGrid（列名，ds）；

GridView grdnew=新建GridView（）；

grdnew.DataSource=dt；

grdnew.DataBind（）；

private DataTable loadDynamicGrid(string [] column,DataSet ds)
{       
    #region Code for preparing the DataTable
    DataTable dt = new DataTable();
    //Create an ID column for adding to the Datatable
    DataColumn dcol ;//= new DataColumn(ID1, typeof(System.Int32));
    ButtonColumn btncolm;
    HyperLinkColumn hplink;
    for (int i = 0; i < column.Count(); i++)
    {
        if (column[i] != "" & column[i]!=null)
        {
            if (column[i] == "BUY" || column[i] == "Buy" || column[i] == "BuyNow" || column[i] == "Details" || column[i] == "ViewDetails" || column[i] == "BuyQty" || column[i] == "Purchase")
            {
                //btncolm = new ButtonColumn();
                //btncolm.HeaderText = column[i];
                //btncolm.Text = column[i];
                //dt.Columns.Add(btncolm.Text);
                hplink = new HyperLinkColumn();
                hplink.HeaderImageUrl = "http://www.google.com";
                hplink.HeaderText = column[i];
                hplink.Text = column[i];
                dt.Columns.Add(hplink.Text);
            }
            else
            {
                dcol = new DataColumn(column[i], typeof(System.String));
                dt.Columns.Add(dcol);
            }
        }
    }
    int k=0;
    foreach (DataRow dr in ds.Tables[0].Rows)
    {
        DataRow myrow = dt.NewRow();
        for (int j = 0; j < column.Count(); j++)
        {
            if (column[j] != "" & column[j] != null)
            {
                string sdfsd = Convert.ToString(dr[column[j]]);
                if (column[j] == "BUY" || column[j] == "Buy" || column[j] == "BuyNow" || column[j] == "Details" || column[j] == "ViewDetails" || column[j] == "BuyQty" || column[j] == "Purchase")
                {
                   //myrow[column[j]] = "http://www.google.com1/";
                   myrow[column[j]] = dr[column[j]];
                }                    
                else
                {
                    if (Convert.ToString(dr[column[j]]).TrimEnd() == "&nbsp;")
                    {
                        myrow[column[j]] = "";
                    }
                    else
                    {
                        myrow[column[j]] = dr[column[j]];
                    }
                }
                if (column[j] == "Stock" || column[j] == "QtyInStock" || column[j] == "Qty" || column[j] == "Available" || column[j].ToLower() == "onhand" || column[j] == "QuantityOnHand" || column[j] == "QtyAvailable" || column[j] == "InStock" || column[j] == "Avail" || column[j] == "Inventory" || column[j] == "Quantity" || column[j] == "Availability")
                {
                    if (Convert.ToString(dr[column[j]]) != "0" && Convert.ToString(dr[column[j]]) != "" && dr[column[j]] != null && Convert.ToString(dr[column[j]]).TrimEnd()!="&nbsp;")
                    {
                        stock = dr[column[j]].ToString();
                    }
                }
            }
        }
        k++;
        dt.Rows.Add(myrow);          
    }       
    #endregion
    column = null;
    return dt;      
}

然后我每次都添加到div中，比如：

mydiv.Controls.Add（grdnew）；

如上所述，我重复循环不同的数据表以绑定到gridview。这里我需要一个链接按钮到网格。所以我添加了一个超链接列到数据表，但我没有得到任何链接按钮在网格。我有20多个数据表要绑定到网格。所以我更喜欢动态创建网格。

Answer 1

只需将网格替换为datagrid，并将hyperlinkcolumn添加到datatable中，并将数据作为click me 提供给该列

DataTable dt=new DataTable();
HyperLinkColumn hplink = new HyperLinkColumn();
hplink.Text = column1[i];
dt.Columns.Add(hplink.Text);
DataRow myrow = dt.NewRow();
myrow[column1[l]] = String.Format("<a href='" + imageUrl(gettablename(tablename)) + "' target='_blank'>" + dr[column[j]] + "</a>");
 dt.Rows.Add(myrow);
 DataGrid1.DataSource=dt;
 DataGrid1.DataBind();

这就是问题的解决。

Answer 2

    TableCell tc1 = new TableCell();
tc1.Wrap=true;
this.lnkRecvGpNo=new LinkButton();
lnkRecvGpNo.Text="RecvGp No";
this.lnkRecvGpNo.Click+=new EventHandler(lnkRecvGpNo_Click);
tc1.Controls.Add(lnkRecvGpNo);
