I have a gridview with a template column that causes a postback on check changed in order to change display. It works fine:
[Code]....
And the code behind:
[Code]....
Works great, right? Well I wrote a small javascript file to make the checkboxes mutually exclusive, but now, while the post back refreshes and the javascript works, it does not show the popup extender anymore - it doesn't even enter the codebehind function.

i have a column in a gridview with an imagebutton in a column. i added an onclientclick event so that a html confirm dialog shows with ok and cancel button, so that if you click cancel, the event should not continue, but if you click ok, the gridviews onrowcommand should fire. The grid is as follows:
[Code]....
[Code]....
but when i click the button on the grid, the alert comes up and if i select ok, i get the following exception:
[Code]....
I'm using the OnClientClick to return the confirm message box. This is what i have so far:
[Code]....
I want to be able to pass one of the fields to it, such as a name, to enhance the confirmation. I want it to be more informative by adding the product or customer name. This should make it read more like this "Are you sure you want to delete the customer Jones?" I suspect I will have to use the {0} but don't understand what I will need to do to get this to work.
I have a datagrid that has 3 checkboxes (checkbox1, checkbox2 and checkbox3). Before i update a record to the database i want to run a validation script on The checkboxes. The function should check that CCheckbox is checked or Unchecked if not checked any all checkboxes sshould fire Validation mssg like "Please check box" any custom validations or javascript validation i am using asp.net with C# very Urgent.

View 2 Replies I have a page for a product listing using a datalist control. I have customized the item template and added a link button that says Click to Order. I then databound that linkbutton with the onclientclick to the "ProductID" field, but I would like to set a variable or use some method of getting the productID of which item they clicked so I can add that product to an order. I cannot understand how to find out which item was clicked though... here is my code:

Why doesn't my "return confirm ()" work in my gridview template control ?
When I click on select the row the onclick event happens but the OnClientClick never happens.

I want to display a warning message and then open a panel on my form in response to a button click in my gridview.
I have used this on another form with a delete command in a gridview column and it work perfectly.
Why isn't it working with my select command ?
Here is the code:
<asp:LinkButton
ID="LinkButton3"
runat="server"
CommandName="Select "
OnClientClick
=
"return confirm='Are you sure that you want to delete this record ?');">Select</asp:LinkButton>
</ItemTemplate> </asp:TemplateField>
I want to Add, edit, delete and update the records using gridview with validations.
I am not using any default datasources like sqldatasource or accessdatasource.
Want to do it in code behind.
Validations should be used as if some one try to update the value as blank or do not enter characters/numbers like that.
I have an image button in my gridview which I'm using to open a new window.
The code for my image button is:
[Code]....
This works fine, in that a new window is opened correctly, however, clicking the button causes a blank row to be added to the top of my grid.
I have a GridView with a couple of buttons (asp:Button) in it (last row). Both of them have a CommandName attribute on them and this is handled server side in a grid_RowCommand event handler. Now, this works fine. However, I need to add client side code (Javascript/jQuery) to disable the two buttons when someone clicks on or the other. This is to prevent the user from double-clicking and creating potential havoc.
The way I have done this is by adding OnClientClick on both buttons which calls a javascript function that uses jQuery to disable the two buttons. This works fine, it's just that the page doesn't post back and so the RowCommand event handler never fires.
[code]....
To me this should be much easier, but I can't seem to retain the values that are put in the Insert template upon a validation failure or when the sql fails. This will prevent the user from having to retype everything agin in the event of a failure.
As you can see I am using the Sub Insert_Click and not using an insert through the wizard. so the fields are unbound textboxes on the form. There are 2 dropdowns that provide choices for the other fields.
I pasted in the code using the text only option becuase the format was getting messed up. I probably need more background on why the fields are blanking out.

1. Is it always required to use javascript to do client side validation.
2. If we dont want to use the script then can I write the code in c# for validating a control like text box using the events.
3. If I write the code in c#, does it always requires a postback?
how can I implement validations for controls in c#. I am not familiar with javascript, so is it good to write the validations in c#
I am facing problem related asp.net validations controls. validations are working at only one machine. During troubleshooting I have check configuration settings like web.config ,machine.config file, client side source as well as server side source code but all are the same.
View 9 Replies have a page that has a validation summary control. On this page I have a nested user control (Control1). nside Control1 is another nested control (Control2). I have a CustomValidator on a textbox inside Control2.
Although the validation works on this textbox, the error message doesn't get bound to the ValidationSummary control. Is there limitations to the ValidationSummary control with nested controls?
Validation controls are good to use but plz guide is there a way that I can prevent validation controls to be validate on input and force them to validate on button press ?
e. g. In a textbox if a reqular expression validator is applied requirment is to make validator fire on button press not on entering text.
i need required field validators for few of textboxes and if everything is filled then on clk of submit btn i want to display an alert msg with sme text.so i kept required field validatiors for all txtboxes and in for alert i wrote javascript function...so first the script gets triggered and then the validators?? wat is the soln:?
View 4 RepliesI have a form that uses ASP.NET validations. I am using some inline C# in the aspx to show/hide certain controls depending on a user's role. I would use the Visible property, but there are so many of them, I just decided to do inline C# to show and hide (I know, not best practice, but bear with me for a second). I am having an issue where Page.IsValid is always set to False when I submit my form (when certain fields are being hidden). Will the validations still fire off even if the controls are not even rendered on the pag? Also, if this is not the case, is there an effective way of breaking down Page.IsValid to find out what is setting it to False?
View 2 RepliesI have to customize a validation scheme for my form because required validation is only necessary if 2 other conditions are met; I have this figured out, but is there a way to add the messages to the ValidationSummary Control using C#
View 2 RepliesI have a Gridview control on my webpage which is loaded using a GridViewTemplate dynamically. I have added FormatValidators toemailaddress, date type data fields. I also have a ValidationSummary control to show the error summary at the bottom of the page.Now, on the webpage, when a user enters incorrect data into two emailaddress fields, the ValidationSummary control summarizes the error messages and shows same error message twiceone per row. I think this is a standard behavior of the ValidationSummary control.
My question is, is there anyway to show the error message only once per column i.e. even if two email address fields are incorrect, the error message shown by validationsummary will appear only once instead of twice? I am referring to showing the validationsummary once per column of gridview instead of once per row...
I'm trying to get a textbox to validate onblur. I have the following code:
myPage.aspx:
<asp:TextBox ID="txt1" runat="server" /> <asp:Button ID="btn1" runat="server" Text="Submit" OnClick="SubmitForm"/>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="No text" ControlToValidate="txt1" Display="None">
<asp:ValidationSummary ID="ValidationSummary1" runat="server" />
myPage.aspx.cs:
protected void Page_Load(object sender, EventArgs e)
{
txt1.Attributes.Add("onblur", string.Format("CheckForValue('{0}');", RequiredFieldValidator1.ClientID));
}
protected void SubmitForm(object sender, EventArgs e)
{
if (Page.IsValid)
{
// process ...
}
}
myPage.js:
function CheckForValue(sender) {
var control = document.getElementById(sender);
ValidatorValidate(control);
}
The validation control will validate if I set the Display to Dynamic or Static, but it won't display the error text in the ValidationSummary when the onBlur event is fired (its fine if the form is submitted using the button). Does anyone know if this is a restriction of using the ValidatorValidate function or am I doing something wrong?
I'll try to make it short. I have two validation summarys on one page (one for the LOGIN and one for the REGISTER).
But when i click on the LOGIN button, it shows not only the missing fields from the LOGIN part but also the ones from the REGISTER part.
I was woundering if I could use two validations summaries without that problem ?
And if no, is there any alternative ? Like how do all the websites in Asp.NET do to have two forms or more per page ?
