how can you reset asp control inside a form using javascript?

</form>
I have a couple of fields on a form that will be populated with default values. I would like to put a button that will allow me to reset those fields to their default values if they have been modified. However I would like to avoid the postback so that I don't have data being sent to the database. Is it possible to add a javascript hook such that when that button is pressed I can pull the default values and populate those fields in javascript?

How do I reset an asp.net validation control via JavaScript? The current code sample clears the error message text but does not reset the validation control for the next form submission.
var cv= document.getElementById("<%= MyValidationContorl.ClientID %>");
cv.innerHTML = '';
Update:Here is the full code sample of the form. I can not seem to get the validation controls fire off on another form submission:

cv.innerHTML = ''; [code]....
I have a javascript to enable text boxes when called, I want to trigger this code when a user picks value "Custom" from a dropdownlist, so that I can display/Hide these new textboxes.
function setVisibility(DropDownListID) {
var element = document.getElementById(DropDownListID);
var element1 = document.getElementById("TestBox1");
if (element.value == "Custom") {
element1.visible = !element1.visible ;
}
<asp:DropDownList ID="DateRangeDropDownList" runat="server" Enabled="True" onChange="setVisibility('DateRangeDropDownList');">
<asp:ListItem>Some Value</asp:ListItem>
<asp:ListItem>Custom</asp:ListItem>
</asp:DropDownList>
<asp:TextBox ID="TestBox1" runat="server"></asp:TextBox>
For some reason it doesn't seem to work.

I have FileUpload Control; I need to remove the file content from the control once the operation is done. I am trying to dispose the Filecontrol object but no luck.

I'm a new developer here, working in VB. Have a question that is stumping me as well as some others.
I have a gridview control built. I am not using an <sqldatasource> tag, so I can't use it's autoGenerateSelect/Update/Delete functionality. I have built a template field that has an "edit" link button in it, and by clicking it will fire the grdName_SelectedIndexChanged event of the gridview.
Now, it's in this event where I'm having trouble. I have it coded so that when this event fires, it will build a textbox and button control. Code:
Protected Sub grdResults2_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdResults2.SelectedIndexChanged
Dim row As GridViewRow = grdResults2.SelectedRow
Dim cell As TableCell = row.Cells(6)
Dim txtSeq As New TextBox
Dim btnUpdate As New Button
'build the textbox in the Search_Seq cell
txtSeq.ID = "txtSeq"
txtSeq.Width = Unit.Pixel(20)
txtSeq.Text = row.Cells(6).Text
cell.Controls.Add(txtSeq)
'build the "update" button in the Search_Seq cell
btnUpdate.ID = "btnUpdate"
btnUpdate.Text = "Update"
cell.Controls.Add(btnUpdate)
End Sub
So the textbox and button populate perfectly. I can run it in the browser and it works fine.
How do I go about setting up the event for this button now? Because it's being manually built here in the gridview event, there is no button for me to "double_click" on in the design view to auto-build this event. There are some properties that need to be set on this button to link it up to a new event....and that's where I'm lost.
Hopefully I don't leave any additional information out.
how to find Textbox Control inside DetailsView Control Using Javascript, I tried below but gives an error OBject reference not found
document.getElementById('<%=DetailsView1.FindControl("TextBox1").ClientID%>');
I have written a web usercontrol (ascx). Inside, there is a Panel that I want to show/hide on click of a hyperlink inside the usercontrol.
Normally, this is easy just by doing something like this (the onclick attribute is added to the hyperlink on prerender):
var PanelToShow = document.getElementById('<%=PanelInvoiceHasBeenCreated.ClientID %>');
if (PanelToHide != null) {
PanelToHide.style.display = 'none';
}
but because the ascx control is held within the gridview, the above will assess all the controls (of which there are many in the gridview) with the name 'PanelInvoiceHasBeenCreated'. The only time it will work is when there is 1 row in the gridview. Currently, with my existing code, if I click the hyperlink in any row, it shows/hides the panel in the bottom row of the gridview!
Therefore, my question is how do I get the actual, unique ID I need to show/hide on the correct control in the correct row?

View 4 RepliesScenario:Own rolled jQuery Ajax post to validate an input field on unfocus Standard submit button for post on form
If I cause validation to fire and wait until I see it complete in firebug then click save all is fine. If however I leave a change in a field and then click the submit button directly (so both ajax and standard post happen at almost the same time) the request hangs in the browser before returning a 'connection reset'. If running in VS debug I see nothing unless I hit pause. I am then presented with the following callstack:

Background:ASP.NET 4 MVC 2 Web application with some legacy webforms pages (the page involved in both the ajax post and standard post is the same webforms page) running locally on Win7/IIS7.
I could potentially disable the submit button while the ajax validation fires. However even if I do that I'm intrigued to know what has caused this seemingly time based/concurrent request problem.

I'm working on a web where i have a Tabcontainer in which I only use two tabs, and what i do there is that I added a control to show virtual keyboard (VK) for use with tablet PC or mouse, it will appear when a textbox is onFocus.
The problem is that when I add the control VK inside a Tabpanel, run the page, and when I focus the textbox inside the Tabpanel, it doesn't appear the VK, but i try using outside the tabpanel and it work. I also added an updatepanel inside the Tabpanel, and moved the textbox and VK control there, but is the same, it doesn't appear the VK.
i will show my web code and a link to the VK control web, cause I think it have to be a way to call the keyboard in client-side mode, but i tryed all i know and nope, isn't showing the VK.

I have Telerik RadGrid with a custom edit form. In my edit form there is a RadDatePicker to which I have added a custom footer template containing a 'Today' button. In the OnClick event of the button I call a Javascript function which takes the control ID to set the selected date. However, because the control is inside the edit form there is no variable created for it and the compiler throws an error when I try getting the client ID. The RadDatePicker is declared with:
<telerik:RadDatePicker ID="ControlName" runat="server" SelectedDate='<%# Bind("Field") %>'>
<Calendar ID="Calendar1" runat="server">
<FooterTemplate>
<div style="width: 100%; text-align: center; background-color: Gray;">
<input id="Button1" type="button" value="Today" class="button"
onclick="GoToToday('<%= ControlName.ClientID %>')" />
</div>
</FooterTemplate>
</Calendar>
</telerik:RadDatePicker>
The error I get is CS0103: The name 'ControlName' does not exist in the current context on the line referencing the ClientID. Is there another way in which to get the ID to pass to the Javascript function?
