问题描述
大家好，我有一个gridiview，称为父Gridview，在父下还有一个gridview，称为子Gridview.在父" Gridview下，我有一个名为展开/折叠"的图像按钮.如果我单击展开"，则对应的行将展开并显示intter gridview.假设我没有打开更多的内部网格视图，现在我想一次关闭所有内部网格视图.通过在父gridview标头使用一个图像对接.请给我脚本想法，一次折叠所有内部gridview.谁能帮我.

Hi all, I have a gridiview, called parent gridview, under parent one more gridview is there called as child Gridview. Under Parent gridview I have an image button called Expand/Collapse.

C#代码
C# code
protected void grvRecords_RowDataBound(object sender, GridViewRowEventArgs e)
{
try
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DataTable dtChildTable = BindChildGridview();
DataTable dtCloneChildTable = dtChildTable.Clone();
//Image img = (Image)e.Row.Cells[1].FindControl("img1");
Image img = (Image)e.Row.FindControl("img1");
Literal ltrl = (Literal)e.Row.FindControl("lit1");
ltrl.Text = ltrl.Text.Replace("trCollapseGrid", "trCollapseGrid" + e.Row.RowIndex.ToString());
string str = "trCollapseGrid" + e.Row.RowIndex.ToString();
e.Row.Cells[1].Attributes.Add("OnClick", "OpenGridTable('" + str + "','" + img.ClientID + "')");
e.Row.Cells[1].RowSpan = 1;
System.Web.UI.WebControls.GridView gvChild = (System.Web.UI.WebControls.GridView)e.Row.FindControl("gvChild");
Label lbliPatId = (System.Web.UI.WebControls.Label)e.Row.FindControl("lbliPatientId");
//DataRow[] gvChildRows = dtChildTable.Select("iPatientId = " + e.Row.Cells[0].Text);
DataRow[] gvChildRows = dtChildTable.Select("iPatientId = " + Convert.ToInt32(lbliPatId.Text));
foreach (DataRow gvChildRow in gvChildRows)
{
dtCloneChildTable.ImportRow(gvChildRow);
}
gvChild.DataSource = dtCloneChildTable;
gvChild.DataBind();
}
}
扩展单个内部gridview的脚本
Script for Expand individual inner gridview
<script language="javascript" type="text/javascript">
//debugger;
function OpenGridTable(trRow, imgId) {
object = document.getElementById(trRow);
if (object.style.display == "none") {
object.style.display = "";
document.getElementById(imgId).src = "Images/Collapse.gif";
}
else {
object.style.display = "none";
document.getElementById(imgId).src = "Images/Expand.gif";
}
}
</script>
推荐答案
将命令名称设置为父gridview标题处的按钮，名称为"CollapsAll".处理"CollapsAll"命令的方法如下:
Hi,
Set the command name to the buttion at parent gridview header as "CollapsAll". Handle "CollapsAll" command as follows:
protected void gvEmpDetails_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "CollapsAll")
{
fnCollapsAll();
}
}
现在在fnCollapsAll中，将所有子网格视图数据源设置为null，如下所示:
Now in fnCollapsAll set the all child grid-view data source to null as follows:
private void fnCollapsAll(){
foreach(DataRow row in grvRecords.Rows){
GridView gv=(GridView)row.FindControl("gvChild");
gv.DataSource=null;
gv.DataBind();
//If you don't want to set the datasource as null just make it
//gv.Visible = false;
}
}
祝一切顺利.
