gridview行颜色 [英] gridview row colors

问题描述

我正在使用GridView模板显示数据，这里我有两列实际值，估计费用.如果实际成本超过了估算成本(然后是估算的实际成本)，我必须在GridView中动态更改该行的颜色.

I am using GridView templates for displaying data, Here i have two columns actual, estimate costs. If there actual cost cross the estimate cost(actual cost grater then estimated), I have to change that row color dynamically in GridView.

推荐答案

Handle RowDataBound GridView事件，然后在那儿应用您的逻辑.

RowDataBound 事件将在DataBound

Handle RowDataBound event of the GridView and apply your logic over there.

RowDataBound event will fire at every row which is created while DataBound

创建的每一行触发，对于Datagrid事件为"ItemDataBound"，对于Gridview事件为"RowDataBound" '.

样本:

For Datagrid the event is ''ItemDataBound'' and for Gridview the event is ''RowDataBound''.

sample:

protected void DataGrid_ItemDataBound(object sender, DataGridItemEventArgs e)
{
     Textbox tbx1 = (TextBox)e.Row.FindControl("ActualCostTextbox");
     Textbox tbx2 = (TextBox)e.Row.FindControl("EstimatedCostTextbox");
     if (tbx1 != null & tbx2 != null)
     { 
         // compare, validate the values of tbx1 & tbx2
         // you got tbx1.Text & tbx2.Text value here. 
         // Do any calculation desired.
         // based on it logic, set the CSS of the row.
     }
}

尝试一下

protected void CustomersGridView_RowDataBound(Object sender, GridViewRowEventArgs e)
  {
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
      Textbox tbx1 = (TextBox)e.Row.FindControl("ActualCostTextbox");
      Textbox tbx2 = (TextBox)e.Row.FindControl("EstimatedCostTextbox");
      if (tbx1 != null&&tbx2 != null)
      {
         // Your code.....
      }
    }
  }
