分页时使GridViewRows突出显示 [英] Keep GridViewRows highlighted when paging

问题描述

我有一个问题，不确定如何相应地解决.
我有一个GridView，如果您在RowCommand事件中使用select命令选择了一行，我会将行的颜色更改为橙​​色，但是当我在Gridview中翻页时如何保持选择的行为橙色?以及如何取消选择行，以使它们不再突出显示?

这是我在RowCommand事件中使用的:

Hi I have a problem and not sure how to do it accordingly.
I have a GridView and if you select a row using the select command in the RowCommand event I change the color of the row to orange but how do I keep the rows that I have select orange when I page through the Gridview? And how do I unselect the rows so that they are not highlighted no more?

This is what I am using in my RowCommand event:

index = Convert.ToInt32(e.CommandArgument)
          If selectedRow.BackColor = Color.Orange Then
            selectedRow.BackColor = System.Drawing.ColorTranslator.FromHtml("#738A9C")
            strPanr = selectedRow.Cells(1).Text
          Else
            selectedRow.BackColor = Color.Orange
            strPanr = selectedRow.Cells(1).Text
          End If

我尝试制作所有选定行的ArrayList并将其存储在Session变量中，但是每次我选择新行时，ArrayList都是空的，Session变量也为空.

I tried to make an ArrayList of all the selected rows and store it in a Session variable but everytime I select a new row the ArrayList is empty and also the Session Variable.

Any help would be much appreciated

推荐答案

您可以在上述代码中使用viewstate....

You can use viewstate for above code ....

Dictionary<int,> dictionary = new Dictionary<int,>();

if(!Session["ListValue"])
{
       dictionary =(Dictionary<int,bool>)Session["ListValue"]
}

index = Convert.ToInt32(e.CommandArgument)
          If selectedRow.BackColor = Color.Orange Then
            selectedRow.BackColor = System.Drawing.ColorTranslator.FromHtml("#738A9C")
            strPanr = selectedRow.Cells(1).Text
         if(dictionary.ContainsKey(index))
          { 
        dictionary[index]=false;
          } 
else
{
dictionary.Add(index,false)
}
          Else
            selectedRow.BackColor = Color.Orange
            strPanr = selectedRow.Cells(1).Text
 if(dictionary.ContainsKey(index))
          { 
          dictionary[index]=true;
          } 
else
{
       dictionary.Add(index,true)
}

          End If
Session["ListValue"]=dictionary;
