Forms Data Controls :: RowDataBound Event Calculations-sum(field) Where ClientID=@clientID; Date + Int = Date?
Oct 26, 2010
I have a databound gridview that displays basic customer information. I have added a template field to the gridview, but I am having trouble with the coding for the RowDataBound event. I need to take the sum of all payments made by the customer in each row and store it in a variable for further calculation. Also, I need to take an integer value (say 30, representing 30 days) and add it to a date, and return a date.

I get the ClientID of a control in ItemCreated event like this: 'ctrl0_spanLoader'
and when it is rendered like this (from view source of IE): 'CtlCategory1_ProfiledBasedSearchResult1_ListViewSearchResult_ctrl0_spanLoader'
This happens in Asp.Net 4 and I have no problems in Asp.Net 3.5.
How do I get the real clientID from ClientID property of my control? Is it a matter of configuration or anything else?

In the XHTML for a page I have:-
<asp:Button ID="bookNowButton" runat="server" CssClass="bookNowButton"
OnClientClick="showHideLoggedInDiv('<%=bookingFormDiv.ClientID%>')" />
This breaks. I need the correct syntax or method to insert the bookingFormDiv.ClientID into the control.

I'm having a problem with <%= obj.ClientID %> expansion, in a .ascx user control.
I have a .js file, containing a javascript function:
function doSomething(objectId)
{
...
}
I have a .ascx file, with some html elements, and in one element's onclick= I want to call doSomething(), passing the ID of an element in that .ascx file, where the passed ID is of an element other than the one being clicked on, so I can't use "this.".
Maybe it'd be clearer with an example.
This works:
<script type="text/javascript">
function redirect()
{
doSomething('<%= top.ClientID %>');
}
</script>
<div id="top" runat="server">
<img src="..." alt="..." onclick="redirect();"/>
</div>
But this does not:
<div id="top" runat="server">
<img src="..." alt="..." onclick="doSomething('<%= top.ClientID %>');"/>
</div>
When I look at the source, I see that the <%=%> substitution has not happened, instead of "doSomething('ctl00_myControl_top');" I get "doSomething('<%=top.ClientID %>');"
For some reason, the script expansion happens in the former case, but not in the latter. The work-around, of course, is not acceptable because it will break if I include multiple copies of the control on a page - only one instance's "redirect()" function will be accessible.

I have a page with a FormView on it. The page is strictly for adding records to a Table. I have the FormView bound to an EntityDataSource and everything works greate except for one thing.
I want to initialize a date field in the FormView to today's date. So, in my page_load event I have:
if (!Page.IsPostBack)
{
//Initialize SetupDate to today.
TextBox setupdate = (TextBox)fvJob.FindControl("txtSetupDate");
setupdate.Text = DateTime.Now.ToShortDateString();
}
The first time this page loads, the txtSetupDate field is initialized.
Although, and subsequent loads of the page doesn't initialize the Text Box. I step through the code in the debugger and I can see that the code is executig, but something (the FormView bind?) is "clearing" the Text Box.

I have a databound gridview in which i have added a template field to display a calcultion. I have created a rowdatabound event in which I want to perform a calculation, but don't know how. The calculation is as follows:
First, it should take the sum of all the payments made by a given customer. It then should divide this value by a daily membership rate, returning a days paid variable. Finally, it should add that variable to the customer since field and calculate the date that the customer is paid through.

I am filtering dataview using my Date Column but the result is not proper because the Field value also stores time, so I want to convert this Date Field to only Date during Filter. How can I achieve this? Here is my code. And the actual value I am getting in the Dataset Field "CreationDate" is a DateTime field which is like
2010-01-21 14:35:25.203
2010-01-22 12:55:18.033
2010-01-26 12:10:06.990
But I only want to neglet time value and want to compare Date only.

found that when I get the Request.Form("__EVENTTARGET") on a postback and compare it to Control.ClientId it is not equals.
ctl00$ContentPlaceHolder_MainContent$DropDownList_CantidadAcompanhantes
ctl00_ContentPlaceHolder_MainContent_DropDownList_CantidadAcompanhantes
My Code:

This line "If ctrlName = DropDownList_CantidadAcompanhantes.ClientID Then" is never equals.

I know that variations of this same question have been posed numerous times - but I can't quite seem to find the exact solution.
I would like any row in my gridview where the boolean field "Approved" is True to be shaded gray. Here is the code that I'm using, but every row ends up being gray, regardless of the value in that "Approved" field. My guess is that I'm not correctly evaluating the boolean value in this field (which is actually a yes/no field in MS Access), Not sure if I should be reading that value as "-1", "Yes" or "True" or "NotNull"? Anyway, here is the code:

I like to know how to get the ClientID/UniqueID of a control inside a Detailsview controls EditItemTemplate element and when DetailsViews changing to Edit mode and DetailsView is inside a AJAX UpdatePanel. Without UpdatePanel, during PostBack I can get the ClientID's control, but now with an UpdatePanel.
[Code]....
As you see, the EditItemTemplate contains a Checkbox control. So i'm trying to get the ClientID of this checkbox when Detailsview is changing to the Edit mode. I need this value for handling Javascript.
Catching the events ChangingMode/ChangedMode doesn't work; chkbox is null:
[Code]....
Maybe i'm using the wrong event? Someone can give me a tip about this?

I have an "effectivedate" field that is displayed using a label inside a detailsview control... In the code behind I need to add 12 months to this to check if a policy is up for renewal or not...
To find the control I use this code... Dim EffectiveDate As Label = DetailsView1.FindControl("EffectiveDatelbl").ToString
But when I try and convert the label to datetime type using this... Dim ExpireDate As DateTime = EffectiveDate.AddMonths(12)
I get the error - Cannot convert string to date, addmonths is not a member of label etc...

I have a gridview that has a field called TargetDate which is formatted as dd/mm/yyyy. I want to substring the numbers out of the date. So basically remove the '/'. How do I do that? can't just substring(0,2) because sometimes the date is single digits, sometimes 2 digits. I am using vb.net.

I have a formview. Inside, there is a textbox where user can input a date(txtAccepDt). Then the user will choose one item from a radiobutton list which has values like 60 days, 90 days and 150 days. If the user select the 60 days I need to add that to the Accept date and show it in a abel(lblShowFrstOp). Same will apply with other two day

I am trying to create a listing for a ticket company. When the user(client) adds a new ticket to the listing, all the ticket info is saved into the database table, but I can't figure out how to get their clientID in the table with that post. For example, I have event, date, venue, row, section etc...all this info gets stored, but I need to have the clientID stored also, so the gridview can show the post when the client logs in/out from the app. Right now the only way the clientID is in the DB is because I manually put it there for development reasons. But, when the client adds a new item to their listings, it does not show until I put the ID in myself. I need the ID to insert in the CID column at the same time the rest of the info is stored.

I have a page that belongs to a master page, and I'm having trouble getting the correct clientId to use in javascript. I have a textbox defined as:
<asp:TextBox ID="ui_tbDOB" runat="server" Width="75px" onchange="SetAge();"></asp:TextBox>
In my javascript SetAge() function I go to get the field by doing this:
var ui_tbDOB = document.getElementById('<%=ui_tbDOB.ClientID %>');
When I view my page source my textboxId ends up being:
<input name="ctl00$cphMainBody$ui_tbDOB" type="text" value="06-06-1983" id="ctl00_cphMainBody_ui_tbDOB" onchange="SetAge();" style="width:75px;" />
All good so far, except that my javascript ends up being: var ui_tbDOB = document.getElementById('ctl00_cphMainBody_ui_tbDOB');
, the two don't match up, and my javascript fails:
'ctl00_cphMainBody_ui_tbDOB' is not equal to 'ctl00$cphMainBody$ui_tbDOB'
