Hello everyone,
I am calling function for generating excel on click event of button.It works fine and generating the desired output.But,i have one text box on the page,i want to clear it after generating the excel.it is preserving the values even after the excel generation. I tried string.empty after function call but it did not worked. I want to know about the way how to forcefully clear the text box at certain time?Any help would be greatly appreciated.

0	I think you need to share your function code to get idea where you are clearing textbox.. and find cause for same.. You can write a javascript function to clear your textbox in page and call it from code behind file using ClientScriptManager.RegisterClientScriptBlock, after creating Excel File. http://hashtagakash.wordpress.com/ Rohanleuva, if this helps please login to Mark As Answer. \| Alert Moderator

Create a javarcipt function something like this: function A(){ alert(document.getElementByID("textbox1.text")); document.getElementByID("textbox1.text").value = ''; } Write one line code after Excel() in your function to call that javascript Method ClientScript.RegisterOnSubmitStatement(this.GetType(), "ConfirmSubmit", "A();"); http://hashtagakash.wordpress.com/ Rohanleuva, if this helps please login to Mark As Answer. \| Alert Moderator

Try textbox1.text = "";
R u Using ASP.Net ?

Create a javarcipt function something like this:
function A(){
alert(document.getElementByID("textbox1.text"));
document.getElementByID("textbox1.text").value = '';
}

Write one line code after Excel() in your function to call that javascript Method

ClientScript.RegisterOnSubmitStatement(this.GetType(), "ConfirmSubmit", "A();");

document.getElementByID("TextBox1.text").value = '';
}

0	None of the implementations worked...I am not able to figure out the problem....Why the textbox is preserving the values even after the string.empty command. It means that,this command doesnt affect the state(value) of the textbox,want someone to answer it...WHY? Rohanleuva, if this helps please login to Mark As Answer. \| Alert Moderator

0	Hi, Here, you have to clear your textbox using PreRender event, try the below code protected void Page_PreRender(object sender, EventArgs e) { textbox1.text = string.Empty; } Thanks Lakhan Singh Tech Lead BeyondKey System Pvt.
