单击取消（重置）按钮后单击提交按钮时，验证未触发（未显示错误消息）。
当我在取消按钮之前首先单击提交按钮时，验证工作正常。我已经为两个字段包含了一些javascript验证，并为清除错误消息进行了一次验证。多数民众赞成
（两个文本框的JAVASCRIPT验证在上述条件下都有效）

ASPX.CS代码
我已经包含了明确的字段和许多基本功能！
protected void btnSave_Click(object sender, EventArgs e)
{
int a;
try
{
con.Open();
OracleCommand cmd = con.CreateCommand();
string interests = string.Empty;
foreach (ListItem item in this.chklProjectCompleted.Items) /*Populating selected checkbox values into interests STRING */
if (item.Selected)
interests += item + ",";
string ProjectCompletion= interests.TrimEnd('?', '.', ','); /*Method to trim trailing comma in database */
if (rblProjectStatus.SelectedIndex>0) /*populating radio button with 0 & 1 VALUES */
{
a = 1;
}
else
{
a = 0;
}
cmd.CommandText = "INSERT INTO CMPPOJECT(PROJECTNAME,DESCRIPTION,COMPANY,PROJECTSTATUS,WEBSITEURL,COMPLETEDIN,STARTEDIN)VALUES('" + txtProjectName.Text + "','" + txtDescription.Text + "','" + ddlCompanyName.SelectedIndex + "','" + a + "','" + txtWebsiteUrl.Text + "','" + ProjectCompletion + "','" + txtProjectDate.Text + "')";
cmd.ExecuteNonQuery();
Response.Write("<script>alert('REGISTRATION SUCCESS')</script>");
txtDescription.Text = "";
txtProjectDate.Text = "";
rblProjectStatus.SelectedIndex = -1;
txtProjectName.Text = "";
txtWebsiteUrl.Text = "";

}
catch(Exception ex)
{

}
finally
{

cmd.CommandText = " Select PROJECTNAME,COMPANY,PROJECTSTATUS,STARTEDIN,COMPLETEDIN FROM CMPPOJECT";
DataTable dt = new DataTable();

DataTable Dt = new DataTable();
da.Fill(Dt);
gdDisplay.DataSource = Dt;
gdDisplay.DataBind();
// return Dt;
