搜索gridview的文本框； GridView中文本框内容的onkeypress更改 [英] searching textbox of a gridview; onkeypress of a textbox contents in gridview change

问题描述

我有一个gridview和一个文本框

我想做的就是在每个onkeyup上更改gridview内容的搜索文本框

我做了这部分，虽然

问题是当页面回发时，对文本框的关注丢失了.
当我在代码后面以textbox.focus()的形式编写代码时，文本内的所有元素都将突出显示，而当我再次在textbox Disapper中键入文本时.

有没有办法专注于文本框并取消突出显示?

请帮忙！

对不起，我的英语不好

aspx

i have a gridview and a textbox

all i wanna do is a searching textbox that on each onkeyup the gridview contents changed

i did this part although

the problem is when the page postback, the focus on textbox lost.
And when i write code in code-behind as textbox.focus(), all the element inside the text are highlightened, and when i type again the text inside textbox disapper.

is there a way to focus on textbox and unhighlightened it?

please help!

sorry for my poor english

aspx

function __doPostBack(eventTarget, eventArgument)
        {
            document.Form1.__EVENTTARGET.value = eventTarget;
            document.Form1.__EVENTARGUMENT.value = eventArgument;
            document.Form1.submit();
        }

<asp:TextBox ID="txtLike" runat="server" Width="240px"

                 AutoPostBack="True" onkeyup="javascript:__doPostBack('txtLike','')"

             ontextchanged="txtLike_TextChanged"></asp:TextBox>

代码隐藏

code-behind

protected void Page_Load(object sender, EventArgs e)
    {
            if (Request.Form["__EVENTTARGET"] == "txtLike")
            {
                txtLike_TextChanged(this,new EventArgs());
            }
    }

protected void txtLike_TextChanged(object sender, EventArgs e)
    {
        GridView1.DataBind();
        //SetFocus(txtLike) or txtLike.Focus();
    }

嘿，这个Java脚本对我来说很好用

Hey This Javascript work fine for me

//for serching gridview on keyup
        function Filter(Obj) {

            var grid = document.getElementById('cntPlcHolder_gvDisplay');
            var terms = Obj.value.toUpperCase();
            var cellNr = 0; //your grid cellindex like name
            var ele;
            for (var r = 1; r < grid.rows.length; r++) {
                ele = grid.rows[r].cells[cellNr].innerHTML.replace(/<[^>]+>/g, "");
                if (ele.toUpperCase().indexOf(terms) >= 0)
                    grid.rows[r].style.display = '';
                else grid.rows[r].style.display = 'none';
            }
        }

//调用函数
< input type =''text''onkeyup =''Filter(this);''id ="txtSearch" class ="SmallTextBox" runat ="server"/>

祝你好运

//calling of function
<input type=''text'' onkeyup=''Filter(this);'' id="txtSearch" class="SmallTextBox" runat="server" />

Best Luck
