如何将Onclick Gridview单元格的值插入到Hiddenfield中
这里我想要检索GridView ColumnIndex [1]单元格值而不管行。排可以是任意一行
我尝试过：
< pre lang =Javascript> function fnGethdnVal（hdnCC）{
document .getElementById（< span class =code-string> hdnCC）。value = hdnCC;
}
< input id = hdnCC type < span class =code-keyword> = hidden runat = server / >
protected void TranGrid_RowDataBound（ object sender，GridViewRowEventArgs e）
{
if （e.Row.RowType == DataControlRowType.DataRow）
{
eR ow.Attributes.Add（ onclick， return fnGethdnVal（ + e.Row.Cells [ 1 ]。文字+ ））;
}
}
解决方案
试试这个
e.Row.Attributes.Add（ onclick， fnGethdnVal（' + e.Row.Cells [ 1 ]。文字+ '））;
function fnGethdnVal（hdnCC）{
alert（hdnCC）;
document .getElementById（' <％ #hdnCC.ClientID％>'）。value = hdnCC;
}
示例：
< html < span class =code-attribute> xmlns = http://www.w3.org/ 1999 / xhtml >
< head runat = 服务器 >
< title > < / title >
< ; 脚本 >
function fnGethdnVal（hdnCC）{
alert（hdnCC）;
document .getElementById（' <％ = hdnCC.ClientID％>'）。value = hdnCC;
}
< / 脚本 >
< / head >
< body >
< 表单 id = form1 runat < span class =code-keyword> = server >
< asp：GridView runat = 服务器 ID = TranGrid OnRowDataBound = TranGrid_RowDataBound AutoGenerateColumns = true >
< / asp：GridView >
< asp：HiddenField ID = hdnCC < span class =code-attribute> runat = server / > ;
< / form >
< / body >
< / html < span class =code-keyword>>
public partial class WebForm2 ：System.Web.UI.Page
{
受保护 void Page_Load（ object sender，EventArgs e）
{
if （Page.IsPostBack） return ;
DataTable dt = new DataTable（）;
dt.Columns.Add（ 品牌）;
dt.Columns.Add（ Model）;
dt.Columns.Add（ ID）;
dt.Rows.Add（ Moto， Nexus， 1 ）;
dt.Rows.Add（ Apple， Iphone， 2 ）;
dt.Rows.Add（ Sony， Vaio， 3 ）;
dt.Rows.Add（ Samsung， Edge， 4 ）;
TranGrid.DataSource = dt;
TranGrid.DataBind（）;
}
受保护 void TranGrid_RowDataBound（ object sender，GridViewRowEventArgs e）
{
if （e。 Row.RowType == DataControlRowType.DataRow）
{
e.Row.Attributes.Add（ onclick， fnGethdnVal（' + e.Row.Cells [ 1 ]。文本+ '）） ;
}
}
}
这是给你的一个例子。我添加了行功能的突出显示，以便您可以轻松区分您所在的行。它还将保留回发中的选择：
ASPX：
< head runat = server >
< title > < / title >
< script src = http： //ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js\" type = text / javascript > < / 脚本 >
< script type = text / javascript >
var prevRowIndex;
function HighlighRowAndGetValue（row，rowIndex，cellValue）{
var parent = < span class =code-sdkkeyword> document .getElementById（row）;
var currentRowIndex = parseInt （rowIndex）+ 1 ;
if （prevRowIndex == currentRowIndex）
return ;
else if （prevRowIndex！= null ）
parent.rows [prevRowIndex] .style.backgroundColor = ＃FFFFFF;
parent.rows [currentRowIndex] .style.backgroundColor = ＃FFFFD6;
prevRowIndex = currentRowIndex;
（' ＃<％= Label1.ClientID％>'）。text（cellValue）;
How to insert Value of Onclick Gridview Cell into Hiddenfield
Here I want to retrieve the GridView ColumnIndex[1] Cell Value irrespective of row. Row can be any row
What I have tried:
function fnGethdnVal(hdnCC) {
document.getElementById("hdnCC").value = hdnCC;
}
<input id="hdnCC" type="hidden" runat="server"/>
protected void TranGrid_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
e.Row.Attributes.Add("onclick", "return fnGethdnVal(" +e.Row.Cells[1].Text+ ")");
}
} 解决方案
try this
e.Row.Attributes.Add("onclick", "fnGethdnVal('" + e.Row.Cells[1].Text + "')");
function fnGethdnVal(hdnCC) { alert(hdnCC); document.getElementById('<%# hdnCC.ClientID%>').value = hdnCC; }
Example:
<html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <script> function fnGethdnVal(hdnCC) { alert(hdnCC); document.getElementById('<%= hdnCC.ClientID%>').value = hdnCC; } </script> </head> <body> <form id="form1" runat="server"> <asp:GridView runat="server" ID="TranGrid" OnRowDataBound="TranGrid_RowDataBound" AutoGenerateColumns="true" > </asp:GridView> <asp:HiddenField ID="hdnCC" runat="server" /> </form> </body> </html>
public partial class WebForm2 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { if (Page.IsPostBack) return; DataTable dt = new DataTable(); dt.Columns.Add("Brand"); dt.Columns.Add("Model"); dt.Columns.Add("ID"); dt.Rows.Add("Moto", "Nexus",1); dt.Rows.Add("Apple", "Iphone",2); dt.Rows.Add("Sony", "Vaio",3); dt.Rows.Add("Samsung", "Edge",4); TranGrid.DataSource = dt; TranGrid.DataBind(); } protected void TranGrid_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes.Add("onclick", "fnGethdnVal('" + e.Row.Cells[1].Text + "')"); } } }
Here's an example for you. I've added the highlighting of row feature so you can easily distinguished which row you are on. It will also retain the selection across postbacks:
ASPX:
<head runat="server"> <title></title> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js" type="text/javascript"></script> <script type="text/javascript"> var prevRowIndex; function HighlighRowAndGetValue(row, rowIndex, cellValue) { var parent = document.getElementById(row); var currentRowIndex = parseInt(rowIndex) + 1; if (prevRowIndex == currentRowIndex) return; else if (prevRowIndex != null) parent.rows[prevRowIndex].style.backgroundColor = "#FFFFFF"; parent.rows[currentRowIndex].style.backgroundColor = "#FFFFD6"; prevRowIndex = currentRowIndex;
('#<%= Label1.ClientID %>').text(cellValue);
