I have few textboxes outside the update panel. The text boxes can''t be inside the panel because it contains code that doesn''t run within an update panel. When i click submit button it shows modal pop box which includes two buttons(btnyes and btnNo). I have called "cleartext()" function (which clears all the text box text) for few textbox and also i ll get some values from database to some other textbox in btnyes click event. The problem here is i can''t clear my text box when i click my btnyes. IS it because ,my textboxes are outside the update panel. how can i clear my textboxes? My submit button and modalpopextender was with in content template of update panel and i added trigger for btnyes 解决方案 First write a javascript function in the head of your page.function setTextBoxValues(firstValue,secondValue){document.getElementById('FirstTextBoxID').value() = '';//to clear text of first text boxdocument.getElementById('SecondTextBoxID').value() = '';//to clear text of second text boxdocument.getElementById('FirstTextBoxID').value() = firstValue;//to set new valuedocument.getElementById('SecondTextBoxID').value() = secondValue;//to set new value}On click of button inside update panel write this lineprotected void Button1_Click(object sender, EventArgs e){string firstValueFromDatabase = "valueFromDatabase";//get value from databasestring secondValueFromDatabase = "valueFromDatabase";//get value from databaseScriptManager.RegisterClientScriptBlock(this, this.GetType(), "ClearControls", "setTextBoxValues('" + firstValueFromDatabase + "','" + secondValueFromDatabase + "');", true);} 这篇关于如何访问updatepanel外部的控件的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云! 09-02 19:51
