function divexpandcollapse（divname）{

以上方法用于显示gridview中的下拉列表。

GridViewRow rown =（GridViewRow）（（Control）e.CommandSource）.NamingContainer;

string Sg = gvSuggestion.Rows [rown.RowIndex] .Cells [2] .Text;
objMember.id = ID;

int index = Convert.ToInt32（e.CommandArgument.ToString（））;
DropDownList ddlICM =（DropDownList）gvSuggestion.Rows [index] .FindControl（ddlICM）;

if（ddlICM.SelectedIndex> 0）
{

}
else
{
ScriptManager.RegisterStartupScript（this，this.GetType（），Message，< SCRIPT LANGUAGE ='javascript'> alert（'Please选择创新委员会成员！'）;< / script>，false）;
返回;
}
以上代码在rowcommand上
但我不是
< asp：ImageButton ID = ibSubmit runat = server ImageUrl = 〜/ images / submit-button.png AlternateText = 提交 CommandName = 提交 onclick = ibSubmit_Click CommandArgument = <％＃（（GridViewRow）Container）.RowIndex％> />
按钮点击
解决方案
（＃ + img）.attr（src）==images / plus.png）{
（＃+ img）
.closest（tr）
.after（< tr > ; < td colspan =' 100％' > +
（＃+ divname）
.html（）+< / td > < / tr > ）;
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
function divexpandcollapse(divname) {
var img = "img" + divname;
if ($("#" + img).attr("src") == "images/plus.png") {
$("#" + img)
.closest("tr")
.after("<tr><td colspan = '100%'>" + $("#" + divname)
.html() + "</td></tr>");
$("#" + img).attr("src", "images/minus.png");
} else {
$("#" + img).closest("tr").next().remove();
$("#" + img).attr("src", "images/plus.png");
}
}
</script>
The above method is used to show the dropdownlist in gridview.
<asp:GridView ID="gvSuggestion" runat="server" AllowPaging="false" CssClass="grid"
AutoGenerateColumns="false" DataKeyNames="id"
onrowcancelingedit="gvSuggestion_RowCancelingEdit"

onrowupdating="gvSuggestion_RowUpdating"
onrowdatabound="gvSuggestion_RowDataBound" onselectedindexchanged="gvSuggestion_SelectedIndexChanged"

<asp:TemplateField ItemStyle-Width="20px">

<a href="JavaScript:divexpandcollapse('<%# Eval("suggestion_no") %>');">
<img alt="Details" id="img<%# Eval("suggestion_no") %>" src="images/plus.png" />
</a>
<div id="<%# Eval("suggestion_no") %>" style="display: none; padding-left:10%">
<table style="border-style:solid;border-width:1px;">

<asp:boundfield datafield="date_unauth" headertext="Date Unauth" />
</Columns>
</asp:GridView>
GridViewRow rown = (GridViewRow)((Control)e.CommandSource).NamingContainer;
ID = Convert.ToInt32(gvSuggestion.DataKeys[rown.RowIndex].Value);
string Sg = gvSuggestion.Rows[rown.RowIndex].Cells[2].Text;
objMember.id = ID;
GridViewRow CR = (GridViewRow)((ImageButton)e.CommandSource).NamingContainer;
int index = Convert.ToInt32(e.CommandArgument.ToString());
DropDownList ddlICM = (DropDownList)gvSuggestion.Rows[index].FindControl("ddlICM");
String yourValue = ddlICM.SelectedValue;
if (ddlICM.SelectedIndex > 0)
{
objMember.Pusername = ddlICM.SelectedValue.ToString();
}
else
{
ScriptManager.RegisterStartupScript(this, this.GetType(), "Message", "<SCRIPT LANGUAGE='javascript'>alert('Please select Innovation Committee Member!');</script>", false);
return;
}
the above code is on rowcommand
but i am not accessed dropdown selected item value on the
<asp:ImageButton ID="ibSubmit" runat="server" ImageUrl="~/images/submit-button.png" AlternateText="Submit" CommandName="Submit" onclick="ibSubmit_Click" CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" />
button click
解决方案
("#" + img).attr("src") == "images/plus.png") {
("#" + img) .closest("tr") .after("<tr><td colspan = '100%'>" +
("#" + divname) .html() + "</td></tr>");
