複選框工具提示數據庫

Question

好的，所以我需要一些幫助。我在我的數據庫中有一個表格AgileFactors，它具有以下字段：AgileFactorID，Name和Description。我使用checkboxlist將Name作爲DataTextField，將AgileFactorID作爲DataValueField進行綁定。我想要做的是使用db中的Description域作爲懸停時的工具提示，以顯示每個複選框旁邊顯示的信息圖標。請看下面我的代碼。此刻，我在span標籤內傳遞了一個很長的字符串，這是毫無意義的。任何人都可以幫助我確保工具提示從數據庫中檢索？提前謝謝了！

"SELECT Name, AgileFactorID, Description FROM AgileFactors" 

agile_factors.DataSource = ds2; 
agile_factors.DataTextField = "Name"; 
agile_factors.DataValueField = "AgileFactorID"; 
agile_factors.DataBind(); 


protected void agilefactors_DataBound(object sender, EventArgs e) 
{ 

    var checkBox = sender as CheckBoxList; 
    if (checkBox != null) 
    { 

     foreach (ListItem listItem in checkBox.Items) 
     { 

      listItem.Text = string.Format("{0} <span class='link'><a href='javascript: void(0)'><font face='verdana,arial,helvetica' size='2'><img src='{1}' Height='15' Width='15' /></font><span><b>Project Duration:</b><br/>Ideally, the project should be close to 6 months: much shorter means less iterations, and much longer tends towards long term planning.</span></a></span>", listItem.Text, GetImageFor(listItem.Text)); 

     } 
    } 
} 

private string GetImageFor(string text) 
{ 

    // return image url for check box based on text. 
    switch (text) 
    { 
     case "Project Duration": return "images/iicon.gif"; 
     case "Customer Involvement": return "images/iicon.gif"; 
     case "Acceptance of Change": return "images/iicon.gif"; 
     case "Team Size": return "images/iicon.gif"; 
     case "Skill of Team": return "images/iicon.gif"; 
     case "Organisational and Reporting Structure": return "images/iicon.gif"; 
     case "Process": return "images/iicon.gif"; 
     case "Documentation Requirements": return "images/iicon.gif"; 
     case "Layout of Workspace": return "images/iicon.gif"; 
     case "Empowered Team": return "images/iicon.gif"; 
     default: return null; 
    } 
} 

Answer 1

就像你有一個GetImageFor函數一樣，創建另一個函數來「GetTooltip」。 像其他字段一樣提取工具提示並將其分配給工具提示屬性。

你真的有所有的代碼，所有你所要做的就是去做。我不會爲你做數據庫端，因爲你自己可以做到這一點，你已經證明了這一點。

但這裏要補充的工具提示你去：

int i = 0; 

      foreach(ListItem l in this.CheckBoxList1.Items) 
      { 
       i++; 
       l.Attributes["title"] = "Tooltip " + i.ToString(); 
      } 

下面是結果的屏幕截圖。

格式，因爲你需要，但在這裏你去 -

protected void agilefactors_DataBound(object sender, EventArgs e) 
{ 
    var checkBox = sender as CheckBoxList; 
    if (checkBox != null) 
    { 
     foreach (ListItem listItem in checkBox.Items) 
     {     
      listItem.Text = string.Format("{0} <span class='link'><a href='javascript: void(0)'><font face='verdana,arial,helvetica' size='2'><img src='{1}' Height='15' Width='15' alt='{2}' /></font><span><b>Project Duration:</b><br/>Ideally, the project should be close to 6 months: much shorter means less iterations, and much longer tends towards long term planning.</span></a></span>", listItem.Text, GetImageFor(listItem.Text), GetToolTip(listItem.Value)); 
     } 
    } 
} 

private string GetToolTip(string value) 
{ 
    var x = (from y in ds2.AsEnumerable() 
      where y["AgileFactorID"] == value 
      select y["description"]).FirstOrDefault(); 

    return x.ToString(); 
} 

你將需要修復了，你有什麼，但這應該幫助的一種方式。
