將gridview中的數據添加到會話變量中

我有一個帶有條目，圖書標題和圖像的gridView。將gridview中的數據添加到會話變量中

如何在buttonField單擊事件中將選定的索引書標題和imageUrl分別添加到會話變量，以便我可以在不同的頁面上使用此信息。

我認爲像

string title = (string)GridView1.Rows[GridView1.SelectedIndex].DataItem["Title"]; 
     Session["Title"] = title; 
     Response.Redirect("RateBook.aspx");

上面的代碼是不正確的。在按鈕點擊事件時，如何真正選擇所選行中的單個項目並將其添加到變量中？

你必須這樣做在你的GridView你行命令事件。像...

假設您的按鈕的CommandName是StoreValue但你設置任何

if(e.CommandName == "StoreValue") 
{ 
    GridViewRow row = (GridViewRow)(((Button)e.CommandSource).NamingContainer); 
    string title = row.Cells[ColumnIndex].Text; 

    Session["Title"] = title; 
    Response.Redirect("RateBook.aspx"); 
}

試試這個代碼：

string title = GridView1.Rows[GridView1.SelectedIndex].Cells[ColumnIndex].text; 
Session["Title"] = title; 
Response.Redirect("RateBook.aspx");

用的數代替「ColumnIndex」參數「標題「欄。

試試這個它的工作對我來說

protected void OnSelectedIndexChanged(object sender, EventArgs e) 
      {   
       foreach (GridViewRow row in GridVIew1.Rows) 
       { 
        if (row.RowIndex == GridVIew1.SelectedIndex) 
        { 
         row.BackColor = ColorTranslator.FromHtml("#A1DCF2"); 
         row.ToolTip = string.Empty; 
        } 
        else 
        { 
         row.BackColor = ColorTranslator.FromHtml("#FFFFFF"); 
         row.ToolTip = "Click to select this row."; 
        } 
       } 
       //suppose your index is in cell[0]// 
       Session["Index"] = GridVIew1.SelectedRow.Cells[0].Text; 
}

//你可以使用這個會話//

通過索引獲取詳細信息
