I am looking for a method to format gridview bound data using javascript.
I know you can have custom formating in Eval using:
[Code]....
But I am looking for a way to perform this task on client side, rather than doing it on the server.
For example if I want to format a date field being bound in a custom way, something like emails date received in gmail. (Only show time if it is today's date [15:30] and only show day and month if it is this year date [14 Jan] and show the full date if it is not this year [10/10/2009].
So, how I use javascript to format a field (ie. custom date format or setting a control visibility)?
i want a confirm box from server side code but it's not working
a= a+", "+texbox1.text;
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "confirm", "<script>return confirm('"+a+"'File Already Exists do you want to replace!');</script>");
To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".).aspx
I have an Objectdatasource configured with Select, Insert, Update & Delete queries in a Dataset. This datasource is linked to my Gridview. I do not require all fields in the table to be displayed or updated in my grid so i have turned off the Visible property on several.
However, when i go into Edit mode and trigger the UPDATE to the database table, i get NULL values updated in the columns i set False for the Visible property.
How can i remove these columns from the GridView and the Edit mode and still have them UPDATE with their current values instead of being overwritten with NULL's?

ASP.NET Buttons are not firing OnClink() events if it is placed in content page. There is no problem for master page buttons. This problem I am facing only in windows xp home edition.
i am new to asp.net and need some help with writing a user control that fits the following specification:
i have a list of properties. each property is a string triplet (type, name, value). TYPE can be "boolean", "string", "int" with VALUE taking appropriate values.
so a list of properties would look like: {("boolean", "isMember", "true"), ("int", "age", "39")} .
i need to display the list of properties in a table with a corresponding control for each value type
("boolean" in a CheckBox, "string" "int" in a TextBox)
and be able to to edit the values. I wrote a small control that displays a single property. It puts the NAME in a Label and depending on the TYPE inserts
the value in a TextBox or CheckBox and then puts that in a PlaceHolder. I could afterwards display the list in a table when a button is clicked.
i am added one button on user control it is working fine locally but not working on server my error is CS1061: 'ASP.templates_categories_productsingrid_ascx' does not contain a definition for 'dl_viewall' and no extension method 'dl_viewall' accepting a first argument of type 'ASP.templates_categories_productsingrid_ascx' could be found (are you missing a using directive or an assembly reference?)
I have a form representing a survey that is dynamically generated based on some database configuration. I have a custom server control for rendering the survey (SurveyRenderer) which contains custom server controls for rendering questions (QuestionRenderers). I dynamically add RequiredFieldValidators for questions if they are flagged as being required. I add these validators to the SurveyRenderer's control collection.
The gist of the code...
// In SurveyRenderer.CreateChildControls()... foreach (QuestionRenderer questionRenderer in questionRenderers) { if (questionRenderer.Question.IsRequired) [code]...
The client-side validation works fine -- if someone has omitted a required question, the validators catch it and the form doesn't validate. However if I turn off JavaScript and submit an invalid form, the validators do not seem to work.On the server-side I am calling Page.Validate() and checking Page.IsValid in the submit button click event handler. Despite submitting a form where required questions have been left blank - something that would be caught client-side - on the server-side Page.IsValid remains True.
// In SurveyPage.aspx... public void btnSubmit_Click(object sender, EventArgs e) { Page.Validate();[code]....
Should I be adding the validators to the Page's Control collection, rather than the SurveyRenderer? How come it works on the client-side but not server-side?
UPDATE: My QuestionRenderer is annotated with:
[ValidationProperty("IsValid")]
And the IsValid get method is like so:
// QuestionRenderer.IsValid public bool IsValid { get [code]... If I set a breakpoint and step through, I can see that QuestionRenderer.IsValid is being fired OK. It is returning false when it should do. If I go fine-grained and call in btn_submitClick:
// In SurveyPage.aspx... public void btnSubmit_Click(object sender, EventArgs e) { foreach (IValidator validator in Page.Validators)[code]....
So validator.IsValid is true, even though the call to QuestionRenderer.IsValid returns false. So maybe I haven't wired something up correctly? Is using [ValidationProperty("IsValid")] not enough?

I have a div called address which as a textarea. When I click a hyperlink, it toggles the div up and down. After clicking a an asp.net button the div collapses which is fine, but I noticed the url turns from [URL] to [URL] and now the toggle does not work. Here is the script:
If I enable client side validation in the view I'll get the error per the Attributes from the metadata class. If I take clientside validation out, error gets thrown from saving to the DB rather than return the view with an Error Summary.
This is the top portion of my view....
<% using (Html.BeginForm()) {%> <%: Html.ValidationSummary(true) %>
I've tried running without debugging (ctrl + f5) in debug and release mode as well as setting breakpoints and Debugging (f5) but it just seems weird to get Client side validation without server side validation. What am I missing here?

I have a hidden variable and its value is being updated using javascript(client side) which I make a call from server side code. After making the call I am not able to retrieve the updated value from Server side variable. I went through this forum [URL] but not able find a way how to implement functionality with IFRAME. I am trying to call the client side code and retrieve the updated value from server side in page_load event.
I have created dynamic control with both server and client side events.. if i set client side event server side event is not firing.. I have created the link button which will validate and do some necessary actions.. Validation is working but click event of link button is not firing .. if we remove the client side event , server side event is firing.. how to avoid this.. I want both events..
How could i call a javascript function in server side. I have to call the javascript function on the click of a linkbutton which inside a repeater control.
I have a requirement in which I have to call a JavaScript function in between my server side event and in that JavaScript function code I have to set hidden field value and in next line of that same event i have to use that hidden field value.
I was reading about the fact that you can turn an IFrame control into a server object if you give it the runat="server" attribute. So I did that, for the purpose of running a website WITHIN our network. What I mean is that I want the site that loads INSIDE the frame to be loaded from WITHIN our network's IP address, and not the remote location's (browser's) IP address.Does this not work this way or am I barking up the wrong tree with IFrames?
I have a situation with dozens of remote locations, many of which I cannot easily get static IPs for, using a web based service that has IP restrictions in their hosting environment. I am essentially trying to, via our web server, FUNNEL all the users in the field through our network via an IFrames webpage, so that they can access this service which requires static IPs. They are okay with this, at the service we are using, if I can get this idea working.
VPN is not an option. These users are ehhhhh... no comment. For that matter, I don't feel comfortable with these remote users being on my network as anything but a port 80 web user, because of the potential for viruses.
I have a gridview with several ItemTemplates. The first contains a checkbox the rest contain textboxes. I then added dynamically some bound controls like this:
BoundField bdfPrivName = new BoundField(); clsUtilities.SetBoundFieldCenter(ref bdfPrivName, "PrivName", "Priv Name"); BoundField bdfDescription = new BoundField(); clsUtilities.SetBoundFieldLeft(ref bdfDescription, "PrivDesc", "Description"); BoundField bdfLive = new BoundField(); clsUtilities.SetBoundFieldCenter(ref bdfLive, "Live","Active?"); grdExisting.Columns.Add(bdfPrivName); grdExisting.Columns.Add(bdfDescription); grdExisting.Columns.Add(bdfLive);
I then use FindControl() to locate the checkbox and textboxes and perform my logic based the result foreach (GridViewRow gvr in grdMissing.Rows) { mckbAny = (CheckBox)gvr.FindControl("ckbAdd"); mtxtApplyDate = (TextBox)gvr.FindControl("txtAddApplyDate"); mtxtDateToAdd = (TextBox)gvr.FindControl("txtAddDateToAdd"); mtxtDateToRemove = (TextBox)gvr.FindControl("txtAddDateToRemove"); } etc.
This all worked fine. I then got a request to put the bound fields as the second, third and fourth columns, after the check box and before the textboxes. I found that this was easy to do by changing the Add's to Inserts as follows: grdExisting.Columns.Insert(1, bdfPrivName); grdExisting.Columns.Insert(2, bdfDescription); grdExisting.Columns.Insert(3, bdfLive); It looked fine of the page, but the FindControl(), all of them fail to work.
On my main page, prices are written for different products On another page, i change price of product which is listed on main page I want this change to be affected on main page instantly without postback Ajax Timer control is not a good method for checking value again and again.
