Try the following code
试试下面的代码
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
Button btn = (Button)e.Row.FindControl("btnItem");
btn.Attributes.Add("OnClick","SearchReqsult(this.id);");
}
}

Try with String.Format Class
尝试使用 String.Format 类
<asp:Button ID="btnCheque" runat="server"
OnClientClick=<%#String.Format("return SearchReqsult('{0}');", Eval("ID")) %> />

Can't you do this is databound. Maybe something like this:
你不能这样做是数据绑定的。也许是这样的：
protected void Page_Load(object sender, EventArgs e)
{
yourGridView.RowDataBound += (s, ev) =>
{
if (ev.Row.RowType == DataControlRowType.DataRow)
{
var btn= (Button) ev.Row.FindControl("btnCheque");
btn.OnClientClick = "javascript:SearchReqsult(" +
DataBinder.Eval(ev.Row.DataItem, "Id") + ");";
}
};
}

Enclose your 'id' field in single quotes.
用单引号将您的 'id' 字段括起来。
just replace
只需更换
btn.OnClientClick = "javascript:SearchReqsult(" +
DataBinder.Eval(ev.Row.DataItem, "Id") + ");";
with
和
btn.OnClientClick = "javascript:SearchReqsult(" +
DataBinder.Eval(ev.Row.DataItem, 'Id') + ");";
your code will come as
您的代码将作为
protected void Page_Load(object sender, EventArgs e)
{
yourGridView.RowDataBound += (s, ev) =>
{
if (ev.Row.RowType == DataControlRowType.DataRow)
{
var btn= (Button) ev.Row.FindControl("btnCheque");
btn.OnClientClick = "javascript:SearchReqsult(" +
DataBinder.Eval(ev.Row.DataItem, 'Id') + ");";
}
};
}

Try enclosing javascript function call in single quotes:
尝试用单引号括起 javascript 函数调用：
OnClientClick='javascript:SearchReqsult(<%#Eval("Id") %>);'
OnClientClick='javascript:SearchReqsult(<%#Eval("Id") %>);'
Maybe the problem is with missing/wrong quotes.
也许问题在于缺少/错误的引号。

Try with single quotes instead of double and string.Format()
尝试使用单引号而不是双引号和 string.Format()
<asp:Button ID="btnCheque" OnClientClick=<%# string.Format("javascript:SearchReqsult('{0}');return false;",Eval("id")) %> CssClass="Save" runat="server" />
