Using JQuery Highlight When A Field Is Updated?
Feb 7, 2011
I am working on a web application and I want to incorporate the jQuery Highlight functionality. The way it is set up now is there is a gridview with a link button to add an entry. When you select the link button to add an entry a form appears to fill out all of the information. Once the information is filled out and the user selects "Insert" I would like to have the insert onClick function in the code behind somehow activate the jQuery Highlight command. I can not seem to get this to work.

I'm using a hidden field to store a value in an asp.net page. Basically I set the value of the hidden field whenever a value on the form is changed i.e. first name, date etc. The field is on a webform that has a master page and is in the content section:
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
<asp:HiddenField ID="hdnDirtyFlag" runat="server" Value='false' />
I change the value of the field in javascript by calling a function whenever an onchange event fires in other controls on the web form:
<asp:TextBox CssClass="niceInput" ID="tbFirstName" runat="server" MaxLength="40" Width="150" onchange='SetHiddenVariable();'></asp:TextBox>
<script type="text/javascript">
function SetHiddenVariable() {
// Set the value of the hidden variable so we know a field has been updated
var hiddenControl = '<%= hdnDirtyFlag.ClientID %>';
document.getElementById(hiddenControl).value = 'true';
}
</script>
So far so good. When the page loads the hidden field value is 'false', and if I don't change any values on the webform it remains false. Whenever I do change another control the javascript function gets called and the hidden field value gets updated to 'true'. Again this is all fine.
After I submit the form and update the database, I set the hidden field value back to 'false' in the code behind:
hdnDirtyFlag.Value = "false";
But when I click another button and do a postback, the hidden field value is still at 'true'.
Can anyone explain why this is? I stepped through the code behind and immediately after changing the value I can see the value is 'false'. There is an asp:UpdatePanel on the page but the hidden field is not part of this panel.
EDIT:
This is the code I use to check the value of the field in code behind in the second postback, after it has been set to false in the last step of the first postback. The value remains at true for some reason in the second postback, after it has been set to true in javascript on the client side then set back to false in code behind as shown above:
if (hdnDirtyFlag.Value == "true")
{
UpdateSecurityObject();
}

I am using C# for my programming. I am facing issue, that my hidden variable value is not being updated when it is in update panel. Please see below code for aspx:
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:Timer ID="Timer1" runat="server" Interval="10000" OnTick="Timer1_Tick">
</asp:Timer>
<input type="hidden" runat="server" id="hidCurrentDate" value="" />
<input type="hidden" runat="server" id="hidTripIds" value="" />
<input type="hidden" runat="server" id="hidTripDetails" value="" />
<asp:UpdateProgress ID="uprogTrips" runat="server">
<ProgressTemplate>
<span style="display: block; text-align: center">
<p style="font-family: Verdana; font-size: larger; font-weight: bold;">
<img src="../../Images/ajax-loader.gif" alt="Processing..." /><br />
<br />
Processing...</p>
</span>
</ProgressTemplate>
</asp:UpdateProgress>
<asp:UpdatePanel ID="upTripsGrid" runat="server" UpdateMode="Always">
<ContentTemplate>
<asp:GridView ID="gvAllTrips" runat="server" OnRowDataBound="gvAllTrips_RowDataBound"
OnPageIndexChanging="gvAllTrips_PageIndexChanging" AllowPaging="true" AutoGenerateColumns="false">
<PagerSettings Mode="NumericFirstLast" PageButtonCount="35" Position="TopAndBottom" />
<PagerStyle CssClass="GridPager" />
</asp:GridView>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
<asp:AsyncPostBackTrigger ControlID="ddSortBy" EventName="SelectedIndexChanged" />
<asp:AsyncPostBackTrigger ControlID="ddFilterBy" EventName="SelectedIndexChanged" />
<asp:AsyncPostBackTrigger ControlID="cbPageOptions" EventName="CheckedChanged" />
</Triggers>
</asp:UpdatePanel>
and below is the code where I am trying to update one of the hidden field with my CS code. Interesting, when I am trying to debug its showing all the values, however when I see it f on page source it doesn't give any value. Here is my aspx.cs code:
protected void Timer1_Tick(object sender, EventArgs e)
{
DataTable dtTrips = null;
WEX.Prototype.Data.TripDA tripDA = new WEX.Prototype.Data.TripDA();
string tID = hidTripIds.Value;
string[] tripIDs = new string[1000];
tripIDs = tID.Split(',');
foreach (string tripID in tripIDs)
{
TripSummaryBO tripSummaryBO = tripDA.getTripSummary(Convert.ToInt32(tripID));
if (tripSummaryBO.tripLastEditedOnDate > Convert.ToDateTime(hidCurrentDate.Value))
{
WEX.Prototype.Service.WSProxies WSProxies = new WEX.Prototype.Service.WSProxies();
dtTrips = WSProxies.Build();
Session["AllTrips"] = dtTrips;
dtTrips = (DataTable)Session["AllTrips"];
if (dtTrips != null)
{
if (cnt==0)
{
hidTripDetails.Value = ("Trip name-" + tripSummaryBO.tripName + " was modified by user " + tripSummaryBO.tripLastEditedBy);
}
else
{
hidTripDetails.Value = hidTripDetails.Value + " <br/> " + ("Trip name-" + tripSummaryBO.tripName + " was modified by user " + tripSummaryBO.tripLastEditedBy);
}
BuildGridViewControl(dtTrips);
cnt = cnt + 1;
}
}
else
{
//upTripsGrid.Triggers.Clear();
PageInit();
}
}
}

Im trying to highlight a different element based on the result of a validator.
My form looks like this in structure:
LABEL TEXTBOX VALIDATION CONTROL
When the validation control becomes invalid, I also want the label to change colour.
There are examples of code on the MS website - here is a javascript sample:
[Code]....
isValid always defaults to false and therefore always displays red.

i have two update panels as follows (when linkbutton is clicked i'm trying to highlight div)
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Linkbutton id="btnChange" runat="server"
[code]...
I'm overriding OnLoadComplete and registering this script on page as follows
ScriptManager.RegisterClientScriptBlock(Me, Me.GetType(), "divHigh", "$('#shdr').effect('highlight', {}, 3000);", True)
This highlights the div after postback but the timeout value doesn't work it continues to show highlighted color and doesn't change back.

I'm adding hotkeys to a web application in order to enable keyboard shortcuts for our CSRs to use, to reduce injury and increase calls-per-hour. I'm using an ASP.net UserControl to inject javascript into the page and it's working great. I want the control to "just work", so that when hotkeys are assigned, using a declarative syntax, if the hotkeyed letter exists in the link text, it will be highlighted automatically, so the developer doesn't have to do anything, and also to maintain consistency in visual cues. Here's the code to assign hotkeys, if it matters:
<uc:HotKeysControl ID="theHotkeys" runat="server" Visible="true">
<uc:HotKey ControlName="AccStatus$btnInvoiceEverBill" KeyCode="ctrl+v" />
<uc:HotKey ControlName="AccStatus$btnRefund" KeyCode="ctrl+u" />
<uc:HotKey ControlName="thirdControl" KeyCode="ctrl+p" />
</uc:HotKeysControl>
I want something like:
<a href="whatever" name="thirdControl">Make a <span class=hotkey">P</span>ayment</a>
but I'm not married to the idea of injecting a <span/> in there if there's a better way. How can I do this in CSS or JQuery? Is there a way to pass in a letter to a CSS style and have it change the color of the text displayed? Should I generate javascript to highlight the text when the page loads? What would/did you do in this situation?

i have in my asp.net page a textarea where users type an article="long text" to be saved in the database. In another page i display these articles(textarea) in a :
<p class="p-article">
the text of the article goes here.
</p>
I'd like to filter these articles by search keywords .for example when a user search for "Startup Marketing".
I want to apply the keywords as a filter and get articles and bring those that contain "Startup" or "Marketing" or "Startup Marketinbg".And this in client side by jquery if possible.

I would like to get a field value using an index on an json object.
The json object looks like : {PartList:[{Field1:"echo",Field2:"bravo"},{Field1:"yes",Field2:"no"}]}
I know that if I would like to have the Field1 value it is on the index 0, and for example for the first item in the array:
jsonObject.PartList[0][0] , here the first index is working but the second index given is not. But is it possible to do this ?
