[英]How can I set a table row color in my repeater based on the values databound to that row in ASP.NET?
[英]How to set row color based on column condition in asp.net website
protected void MyGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Image img = (Image)e.Row.FindControl("Status");
int msgid;
int.TryParse(Convert.ToString(DataBinder.Eval(e.Row.DataItem, "MsgID")), out msgid);
string status = Convert.ToString(DataBinder.Eval(e.Row.DataItem, "MessageActive"));
if(status.Equals("No"))
{
e.Row.BackColor = Color.Red;
}
//Based on some condition I am assigning images to the row
if (value >= Toptarg)
{
img.ImageUrl = "Styles/Images/GreenBox.jpg";
img.ToolTip = "Met Top Target";
img.AlternateText = "Met Top Target";
}
else
{
img.ImageUrl = "Styles/Images/AmberBox.jpg";
img.ToolTip = "In Progress";
img.AlternateText = "In Progress";
}
}
}
我有一個gridView,它有一個名為MessageActive的列,在databind行中,我得到了messageActive的值。 如果messageActive值為“Yes”,則不需要進行任何更改。 如果為“否”,我想以紅色顯示特定行,如何設置行數據綁定中的行背景顏色
網格視圖的某些屬性
<RowStyle BackColor="White" />
<AlternatingRowStyle BackColor="MistyRose" />
<FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
<HeaderStyle BackColor="#696969" Font-Bold="True" ForeColor="White" />
命名空間使用System.Web.UI.WebControls; 使用System.Drawing;
我收到了這個錯誤
'Image' is an ambiguous reference between 'System.Web.UI.WebControls.Image' and 'System.Drawing.Image'
Source Error:
Line 56: if (e.Row.RowType == DataControlRowType.DataRow)
Line 57: {
Line 58: Image img = (Image)e.Row.FindControl("Status");
Line 59: int msgid;
Line 60: int.TryParse(Convert.ToString(DataBinder.Eval(e.Row.DataItem, "MsgID")), out msgid);
嘗試這個:
string status = Convert.ToString(DataBinder.Eval(e.Row.DataItem, "MessageActive"));
if (status == "No")
{
e.Row.BackColor = Drawing.Color.Red
}
在您的方法中添加:
if(status.Equal("No"))
{
e.Row.BackColor = Color.Red; // or Color.FromName("#FF0000");
}
作為旁注,我會操縱PreRender
事件處理程序中的顏色或其他樣式,而不是RowDataBound

編輯:您應該將引用添加到.NET程序集System.Drawing,默認情況下它不包含在ASP.NET Web項目模板中...
您需要更改此行:
Image img = (Image)e.Row.FindControl("Status");
要明確引用所需的圖像類,例如:
System.Web.UI.WebControls.Image img = (System.Web.UI.WebControls.Image)e.Row.FindControl("Status");
或者如果你想使用那個類,可以到另一個類。
