Create Asp.net Reset Button - asp.net

Question

Is there any ways to create reset button to clear all text in text fields in asp form? When user hits the reset button, all text entered by them will clear and they are enable to enter back text in the area.

Answer 1

As per my knowledge there is no such reset functionality provided by Asp.Net.
We can achieve the reset like this
btnReset.Attributes.Add("onClick", "document.forms[0].reset();return false;");
Or
Like this
<input type='button' id='resetButton' value='Reset' onclick='theForm.reset();return false;'/>
Or OnClientclick of asp.net button use this theForm.reset();return false;

Answer 2

try this create a button with reset and in click event write ClearInputs(Page.Controls); and event will call this method.
protected void Button2_Click(object sender, EventArgs e)
{
ClearInputs(Page.Controls);
}
void ClearInputs(ControlCollection ctrls)
{
foreach (Control ctrl in ctrls)
{
if (ctrl is TextBox)
((TextBox)ctrl).Text = string.Empty;
ClearInputs(ctrl.Controls);
}
}

In the button click method, set all textbox.text.length values to 0. either do it one by one, which is the simple way, or do it by getting all controls of type textbox on the page, which is tad bit more sophisticated, but could be much less typing, depending on the number of textboxes. Definitely more maintainable.
private void ChangeBtn_Click(object sender, EventArgs e)
{
foreach(Control c in Page.Controls)
{
if (c.Controls.Count > 0)
{
foreach(Control c2 in c.Controls)
{
if (c2.GetType().ToString() == "System.Web.UI.WebControls.TextBox")
{
myspan.InnerHtml = ((TextBox)c2).Text;
((TextBox)c2).Text = ""; //or ((TextBox)c2).Text.Length = 0;
}
}
}
}
}

Answer 4

Create a Click event to the Button control and use the following codes below:
foreach (Control control in Page.Controls)
{
if (control is TextBox)
{
TextBox txt = (TextBox)control;
txt.Text = "";
}
}
This will save you some time to clear all the textboxes inside the web form.

Answer 5

Use Jquery the easiest way to find any type of control and will not have post back event.
$('input[type=text], textarea')
Use foreach loop for clearing value.

Answer 6

Please note that
btnReset.Attributes.Add("onClick", "document.forms[0].reset();return false;");
will not work in clearing pages that are posted back, i.e. If a text box had a value "Silly me" and has been posted back, this code will reset to the post back value which is "Silly me".
The workaround is to repost the page with cleared values - try the following code (it worked for me)
OnClientClick="document.location.href=document.location.href;"
will reload the page with cleared values...

I have multiple type of inputs in my page (TextBox, DropDownList and CheckBox), so here is how I reset them all
Put an <asp:Panel> that wraps my inputs
Run BtnClear_Click on Clear button click
Loop each inputs and reset text/selection/checked value by types
The codes
Default.aspx
<asp:Panel ID="PanelReport" runat="server">
...
<asp:TextBox ID="fldSpeedoMula" runat="server"></asp:TextBox>
<asp:DropDownList ID="ddlPlateNo" runat="server" CssClass="form-control"></asp:DropDownList>
<asp:CheckBox ID="cbCard" runat="server" />
<asp:CheckBox ID="cbCash" runat="server" />
<asp:Button ID="BtnClear" runat="server" Text="Clear" CssClass="button" OnClick="BtnClear_Click"/>
...
</asp:Panel>
Default.aspx.cs
protected void BtnClear_Click(object sender, EventArgs e)
{
// Clear all inputs
foreach (DropDownList ddl in PanelReport.Controls.OfType<DropDownList>())
{
ddl.SelectedIndex = 0;
}
foreach (TextBox fld in PanelReport.Controls.OfType<TextBox>())
{
fld.Text = string.Empty;
}
foreach (CheckBox cb in PanelReport.Controls.OfType<CheckBox>())
{
cb.Checked = false;
}
}
