c# - 搜索特定行时未处理的 GridView 触发事件 RowEditing
问题描述
我有一个带有 2 列的网格视图,一列用于文本框,另一列用于编辑图标。如果我单击编辑图标,它会打开文本框进行编辑,第二列将包含更新图标和取消图标。网格视图上方还有一个搜索文本框,允许用户搜索特定行。
第一种情况:例如,当我有 5 行并单击任意行中的编辑图标时,它将打开编辑框,我可以进行编辑。
第二种情况:当我在搜索字段中键入文本并单击搜索按钮时,它将检索相应的行并将其单独显示在网格视图中。
问题是 当我单击该行的编辑图标(搜索结果)时,它显示: GridView 触发了未处理的事件 RowEditing
这是我的网格视图:
<asp:GridView ID="PSGridView" runat="server" AutoGenerateColumns="False" DataKeyNames="StatusID" DataSourceID="PSSqlDataSource" ShowFooter="True" BorderStyle="None" BorderWidth="1px" Width="100%" ShowHeaderWhenEmpty="True" EmptyDataText="No protocal status."

var exist = 0;
if (e.CommandName == "DeletePS" )
{
some code
}
else if (e.CommandName == "UpdatePS")
{
var exist1 = 0;
//When update, check if the new name is already exist in the database
//*******************************************************************
var index = Convert.ToInt32(e.CommandArgument);
if (index >= 10)
{
index = index % 10;
}
var pageSize = PSGridView.PageSize;
GridViewRow row = PSGridView.Rows[index % pageSize];
TextBox txt = row.FindControl("PSBind") as TextBox;
string t = txt.Text;
exist1 = check_exist(t);
if (exist1 == 1)
{
errorboxactions.Attributes.Add("style", "display:block");
errormsgactions.InnerHtml = "This name already exist ! type another name";
}
//if not exist
//*************
else
{
PSGridView.UpdateRow(index, true);
PSGridView.DataBind();
updateboxactions.Attributes.Add("style", "display:block");
updatemsgactions.InnerHtml = "Protocol Status has been updated successfully";
}
}
}
解决方案
只需为 gridview 做一件简单的事情即可触发 RowEditing 事件.... 按照步骤
select gridview
go to properties
select events and then double click on row editing and then run the page again.
