问题描述
大家好，
我试图通过使用复选框将数据行从一个gridview复制到另一个gridview。因此，只要在gridview1上检查了一行，它就会自动添加到gridview2中，无论何时取消选中，都会将其删除。我确实找到了一些示例代码，并根据我的要求进行调整，但似乎没有正常工作。当我检查一行时，页面确实刷新了，但它没有添加到gridview2。以下是我的代码：
我的主要网格视图：
Hi guys,
I am trying to copy rows of data from one gridview to another gridview by using a checkbox. So whenever a row is checked on gridview1, it will automatically be added to gridview2 and whenever it is unchecked, it will be removed. I did find some sample code and I adjust it to my requirements but it doesn't seem to be working properly. When I checked a row, the page did refresh but it is not added to gridview2. Below is my code:
my primary gridview:
<asp:GridView ID="PrimaryGrid" runat="server" AutoGenerateColumns="False"
BackColor="#DEBA84" BorderColor="#DEBA84" BorderStyle="None" BorderWidth="1px"
CellPadding="3" CellSpacing="2" DataKeyNames="SubActivity"
DataSourceID="SqlDataSource2" EmptyDataText="No data selected">
<Columns>
<asp:TemplateField>
<HeaderTemplate>
<asp:CheckBox ID="checkAll" runat="server" onclick="checkAll(this)" AutoPostBack="true" OnCheckedChanged="CheckBox_CheckChanged" />
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="check" runat="server" onclick="Check_click(this)" AutoPostBack="true" OnCheckedChange="CheckBox_CheckChanged" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="ActivityID" HeaderText="ActivityID" SortExpression="ActivityID" HtmlEncode="false"/>
<asp:BoundField DataField="SubActivity" HeaderText="SubActivity" SortExpression="SubActivity" HtmlEncode="false"/>
<asp:BoundField DataField="Budget" HeaderText="Budget" SortExpression="Budget" HtmlEncode="false"/>
</Columns>
<FooterStyle BackColor="#F7DFB5" ForeColor="#8C4510" />
<HeaderStyle BackColor="#A55129" Font-Bold="True" ForeColor="White" />
<PagerStyle ForeColor="#8C4510" HorizontalAlign="Center" />
<RowStyle BackColor="#FFF7E7" ForeColor="#8C4510" />
<SelectedRowStyle BackColor="#738A9C" Font-Bold="True" ForeColor="White" />
<SortedAscendingCellStyle BackColor="#FFF1D4" />
<SortedAscendingHeaderStyle BackColor="#B95C30" />
<SortedDescendingCellStyle BackColor="#F1E5CE" />
<SortedDescendingHeaderStyle BackColor="#93451F" />
</asp:GridView>
我的次要网格视图：
my secondary gridview:
<div style="removed: absolute; z-index: inherit; removed 185px; removed 765px; height: 215px; width: 249px;">
<asp:GridView ID="FinalReport" runat="server" AutoGenerateColumns="False"
EmptyDataText="No records selected" BackColor="LightGoldenrodYellow"
BorderColor="Tan" BorderWidth="1px" CellPadding="2" ForeColor="Black"
GridLines="None">
<AlternatingRowStyle BackColor="PaleGoldenrod" />
<Columns>
<asp:BoundField DataField="RouteID" HeaderText="Route ID" />
<asp:BoundField DataField="ActivityID" HeaderText="Activity ID" />
<asp:BoundField DataField="Budget" HeaderText="Budget" />
</Columns>
<FooterStyle BackColor="Tan" />
<HeaderStyle BackColor="Tan" Font-Bold="True" />
<PagerStyle BackColor="PaleGoldenrod" ForeColor="DarkSlateBlue"
HorizontalAlign="Center" />
<SelectedRowStyle BackColor="DarkSlateBlue" ForeColor="GhostWhite" />
<SortedAscendingCellStyle BackColor="#FAFAE7" />
<SortedAscendingHeaderStyle BackColor="#DAC09E" />
<SortedDescendingCellStyle BackColor="#E1DB9C" />
<SortedDescendingHeaderStyle BackColor="#C2A47B" />
</asp:GridView>
</div>
这是我获取数据并将其存储到数据表中时的代码将其保存到viewstate：
This is my code to when get the data and store it into a datatable saves it into a viewstate:
private void GetData()
{
DataTable dt = new DataTable();
if (ViewState["SelectedRecords"] != null)
dt = (DataTable)ViewState["SelectedRecords"];
else
dt = CreateDataTable();
CheckBox checkAll = (CheckBox)PrimaryGrid.HeaderRow
.Cells[0].FindControl("checkAll");
for (int i = 0; i < PrimaryGrid.Rows.Count; i++)
{
if (checkAll.Checked)
{
dt = AddRow(PrimaryGrid.Rows[i], dt);
}
else
{
CheckBox check = (CheckBox)PrimaryGrid.Rows[i]
.Cells[0].FindControl("check");
if (check.Checked)
{
dt = AddRow(IntelToIntelDistiGrid.Rows[i], dt);
}
else
{
dt = RemoveRow(PrimaryRecord.Rows[i], dt);
}
}
}
ViewState["SelectedRecords"] = dt;
}
这是设置数据的代码：
This is the code for setting the data:
private void SetData()
{
CheckBox checkAll = (CheckBox)PrimaryRecord.HeaderRow.Cells[0].FindControl("checkAll");
checkAll.Checked = true;
if (ViewState["SelectedRecords"] != null)
{
DataTable dt = (DataTable)ViewState["SelectedRecords"];
for (int i = 0; i < PrimaryGrid.Rows.Count; i++)
{
CheckBox check = (CheckBox)PrimaryGrid.Rows[i].Cells[0].FindControl("check");
if (check != null)
{
DataRow[] dr = dt.Select("RouteID = '" + PrimaryGrid.Rows[i].Cells[1].Text + "'");
check.Checked = dr.Length > 0;
if (!check.Checked)
{
checkAll.Checked = false;
}
}
}
}
}
这个是选中复选框时触发的事件：
and this is the event fired when the checkbox is checked:
protected void CheckBox_CheckChanged(object sender, EventArgs e)
{
GetData();
SetData();
BindPrimaryGrid();
BindSecondaryGrid();
}
我在选中复选框时使用的javascript：
javascript that i use when a checkbox is checked:
function Check_click(objRef)
{
//Get the Row based on checkbox
var row = objRef.parentNode.parentNode;
//Get the reference of GridView
var GridView = row.parentNode;
//Get all input elements in Gridview
var inputList = GridView.getElementsByTagName("input");
for (var i = 0; i < inputList.length; i++)
{
//The First element is the Header Checkbox
var headerCheckBox = inputList[0];
//Based on all or none checkboxes
//are checked check/uncheck Header Checkbox
var checked = true;
if (inputList[i].type == "chckbox" && inputList[i] != headerCheckBox)
{
if (!inputList[i].checked)
{
checked = false;
break;
}
}
}
headerCheckBox.checked = checked;
}
javascript i used if all the checkbox is ticked:
javascript i used if all the checkbox is ticked:
function checkAll(objRef)
{
var GridView = objRef.parentNode.parentNode.parentNode;
var inputList = GridView.getElementsByTagName("input");
for (var i = 0; i < inputList.length; i++) {
var row = inputList[i].parentNode.parentNode;
if (inputList[i].type == "checkbox" && objRef != inputList[i])
{
if (objRef.checked)
{
inputList[i].checked = true;
}
else
{
if (row.rowIndex % 2 == 0)
{
row.style.backgroundColor = "#C2D69B";
}
else
{
row.style.backgroundColor = "white";
}
inputList[i].checked = false;
}
}
}
}
add row function:
add row function:
private DataTable AddRow(GridViewRow gvRow, DataTable dt)
{
DataRow[] dr = dt.Select("RouteID= '" + gvRow.Cells[1].Text + "'");
if (dr.Length <= 0)
{
dt.Rows.Add();
dt.Rows[dt.Rows.Count - 1]["RouteID"] = gvRow.Cells[1].Text;
dt.Rows[dt.Rows.Count - 1]["ActivityID"] = gvRow.Cells[2].Text;
dt.Rows[dt.Rows.Count - 1]["Budget"] = gvRow.Cells[3].Text;
dt.AcceptChanges();
}
return dt;
}
remove row function:
remove row function:
private DataTable RemoveRow(GridViewRow gvRow, DataTable dt)
{
DataRow[] dr = dt.Select("RouteID = '" + gvRow.Cells[1].Text + "'");
if (dr.Length > 0)
{
dt.Rows.Remove(dr[0]);
dt.AcceptChanges();
}
return dt;
}
there’s a few more functions left but i think this 3 is the main one.
p/s : sorry for the long post.

one easy way is there
fetch all data of gridview1 in dataset then gridview2.datasource = dataset;
$ b$b its easy just think
