I'm working on a .NET 3.5 web application which shows/hides table rows contained in ascx files via an interface implementation (the controls containing the table implement the interface).So, given this markup in the .ascx:
<asp:Table id="MyTable" runat="server">
<asp:TableRow ID="Foo" runat="server">
<asp:TableCell ID="FooCell"
[code]...
What i am having trouble doing is set the current parameter to the current row at a specific column like e.row[column index]
For Each trow As TableRow In table.Rows
cmd1.CommandText = "dbo.directway"
cmd1.CommandType = CommandType.StoredProcedure
cmd1.Connection = conn [code]....
Class 'System.Web.UI.WebControls.TableRow' cannot be indexed because it has no default property.
The Get of the Visible property of a control recursively looks up the tree to indicate if the control will be rendered or not.
I need a way to see what the "local" visible value of a control is regardless of what its parent controls are set to. i.e. Whether it itself was set to true or false.
I have seen this question, How to get the "real" value of the Visible property? which uses Reflection to obtain the local state, however, I have not been able to get this working for WebControls. It's also a rather dirty method of getting the value.
I have come up with the following extension method. It works by removing the control from its parent, checking the property, then putting the control back where it found it.
public static bool LocalVisible(this Control control)
{
//Get a reference to the parent
Control parent = control.Parent;
//Find where in the parent the control is.
[Code]....
Is this an acceptable way of doing this? It works fine and I haven't come across any performance issues. It just seems extremely dirty and I have no doubt there could be instances in which it might fail (for example, when actually rendering).
I have the following div:
<div visible="false"
style="background-image:url('../Contents/Images/item-background-selected.png'); width:113px; height:58px; background-repeat: no-repeat; position: absolute;" />
<div>
It's still visible in spite of the visible property is set to false. but when I remove the background-image from the style it's hidden.
How can I hide it with keeping its background?
The Visible property, as I understand it, helps to enable or disable the visibility of a control.
But what is its use in the case of the HiddenField control in ASP.NET?
I need show/hide radiobutton control depends on boolean property

How to bind property visible?
how to retrieve the selected row cell value if it is visible property is false in gridview?
View 1 RepliesI have a form with a ton of gridview controls on it. All of which are driven by a dropdown list control. When I select a value from the dropdown list control it populates the 5 gridview controls with data from the database.If there are no rows associated with the record from the dropdown list then I am going to set the visible property of all of the gridview cotrols to false.
I know how to set the property I just need to know where I would set it and what I would check.I can put my code in the selectedindexchanged event for the dropdownlist control but how do I check to see if there are no rows associated with that value? Maybe some sort of If gridview1_rowdatabound = 0 then...
I have a Sidemenu item in my ASP.NET application like below. There are two types of users in my application (Associates, Managers).When ever Associate Login then I have to disable Manager link. I am not able find visible property in codebehind since it is a HTML control. So need your support how to handle this
<ul>
<li><a href="Associate.aspx?val=Tests&index=0" id="lnkAssociates">Associate</a></li>
<li><a href="Manager.aspx id="lnkManager">Manager</a></li>

I'm getting this error when my Create.aspx view is called and steps over that line:
<%=Html.TextBoxFor(Function(model) model.NO_DEMND, New With {.class = "txtbox", .disabled = True})%>
<%=Html.ValidationMessageFor(Function(model) model.NO_DEMND)%>
The message is there in the Ressources file, I think the problem is deeper than that but i'm having a hard time finding it. It pops this error very early on the ASPX page. It's the first model component it goes thru, i tried removing this one and it's the same message for all the model.xxxx components. I guess it's an error somewhere in the linkage. The .EDMX is correct and I get no build errors,
I have a problem that in DetailsView Edit Mode, if I go to edit fields, and set a fields visible property to false, when I update the record through the built in update options it sends a null value. If I change the field back to visible, it passes the data just fine.
Consequently, I tried just setting the field to Read Only = True, and got the same result even though the current values do show up in the edit mode, just read only.Is there anyway to hide the field but still allow it to pass the data it currently has "BACK" into the record.
Hi I have a situation where I want to set the initial visible property of an Image to False and then in my code change it to True and then run a sub routine. My problem is that no matter how I order the code the sub runs before the image becomes visible. When I debug the image only becomes visible when it hits End Sub. Is there any way around this? Here's my code:

I'm working on some basic form validation styles for an ASP.Net website. I need to select all span elements that are visible, and add a css style to another element. (Just to indicate which input fields are invalid.) The below code works like a charm in FF and Safari, but fails in IE. I've narrowed the problem down to the :visible selector. Here's the jQuery code. IMPORTANT NOTE: Production site is running jQuery 1.3.1 There were changes made to the :visible selector in 1.3.2 release notes
$('span.inputError:visible').each(function() {
$(this).parent().parent().prev('td').children('label').children('span').css('color','red');
});
Here's the rendered HTML it's intended for:
<table width="100%" cellspacing="0" cellpadding="3" border="0">
<tbody>
<tr>
<td valign="top" style="text-align: right;" class="address_labels">
<label><span>*</span> First Name: </label>
</td>
<td>
<span id="ctl00_CMain_txtFirstName_wrapper"><input type="text" style="width: 190px;" invalidstyle="inputError" class="radEnabledCss Input" name="ctl00_CMain_txtFirstName_text" id="ctl00_CMain_txtFirstName_text" size="20" value=" zdogg"><input type="text" value=" zdogg" style="border: 0pt none ; margin: -18px 0pt 0pt; padding: 0pt; overflow: hidden; visibility: hidden; width: 1px; height: 1px;" name="ctl00$CMain$txtFirstName" id="ctl00_CMain_txtFirstName"><input type="hidden" name="ctl00_CMain_txtFirstName_ClientState" id="ctl00_CMain_txtFirstName_ClientState" autocomplete="off"></span>

We have an asp.panel that by default is set to visible=false. When a checkbox is clicked the panel is set to visible=true. The checkbox is set to autopostback and viewstate=true as well as the panel's viewstate =true. This code has worked perfectly for several years and suddenly it has started throwing an error on the built in .net java function below. It doesn't do it in the IDE when you run it either. The bold line is where the exception is being thrown.
function
ValidatorCommonOnSubmit() {
var result = !Page_BlockSubmit;
Page_BlockSubmit = false;
event.returnValue = result;
return result;
}
I have an ASP.NET page that uses a repeater to populate a grid. There will eventually be a dozen or so columns, one of which is a linkbutton that does a postback (it removes the row). The rest of the row I want to be clickable and navigate to the specified url I set up at runtime.
<tr class='normal' onmouseover="this.className='highlight'" onmouseout="this.className='normal'"
onclick="location.href='<%#DataBinder.Eval(Container.DataItem, "url") %>';">
<td><%# DataBinder.Eval(Container.DataItem, "parcel")%></td>
<td><%# DataBinder.Eval(Container.DataItem, "address")%></td>

This "works" ok, but it won't show nothing, since I need the page to be "refreshed" in an "ajax-way" like an UpdatePanel, which I can't use because the Trigger is in another page, right?I really need this to work.. even if you have another completely different way to do this,
How can I trigger the click event of the button if the property Visible="false".
The event will be triggered after the window is close. I am using popup window to trigger click event of the button.
I have a database field called ImageLocation, I have the ImageUrl property bound to: Eval("ImageLocation", "{0}")I would like to bind the Visble property to false if the ImageLocation is null data. I can not figure out how to set the control properly, currently the Datalist shows me all the data and when the image location is null it shows me the name of the Hyperlink control which happens to be Hyperlink2.
View 2 RepliesI'm iterating through a collection of asp:tablerows to be able to get or set the text in a textbox that is nested in the third cell of the row; I'm doing this by type rather than by ID because the cell ID's in that column aren't totally consistent--thus I can't really call FindControl() to achieve this. I've resorted to casting the third control in the TableRow to a TableCell and then Casting the first control in that cell to a TextBox. Not quite correct, as I'm getting an index out of range exception thrown. The problem mainly lies in the Controls.Count() property of the third cell, which comes to zero. Not sure if there's a better way to access the textbox---should I resort to FindControl()?
foreach (TableRow row in tblProviders.Rows) {
string value = ((TextBox)((TableCell)row.Controls(2)).Controls(0)).Text;
...
}
My searches here only yielded use of FindControl(), so that may be the only way...
I have a label1 in my aspx page, which property is set to visible = "False".
In the view source of the browser i cant able to find that label1.But using some other third party tool like "Burp Suite" etc ...
Can those label1 value could be seen or not using tools like "Burp Suite" etc ?
I have two Repeater controls, each hosted in a user control. Both user controls are contained in the same aspx page. Only one User Control is visible at any one time. The repeaters are comprised of checkboxes, and text boxes for user input.
The aspx page is configured with an Ajax ScriptManager; and contains several Ajax UpdatePanels. These UpdatePanels result in partial page post backs when text is changed in a textbox control in controls on the aspx page (this is not the behaviour for the Repeaters in the User Controls). Through use of several AsyncPostBackTriggers, various controls contained in the other UpdatePanels on the page have their content refreshed in response to the partial page post backs they are configured be notified about.
Depending on a radio button group selection, I set the visible property to true or false - as appropriate for the User control containing a repeater control. The Repeater control is then populated with data using databinding. All of this works.
However, when the Submit button is clicked, the Repeater control contains no data.
Given that I am not dynamically adding the Controls containing the Repeater controls (but using Visible true / false). I would have thought that the State of the fields and the data in the visible control would be preserved during the post back.
The User Controls are contained within the UpdatePanel that contains the Submit Button.
I have explicitly Enabled View state without any effect.
Am I correct in assuming that I should not have to do any explicit handling of data changes the user makes (via client side script and manipulation of an Data Structure Representing the Repeater Data); and the View State should maintain the data I need to access on the server when submitted?
I do not believe that it is the User Control visible state changes that are causing the issue because when the page is initially loaded on of the User controls is populated with dummy rows (so it displays).
I am suspicious that because the visible state of the controls is changed during partial page post back, that the Page View State ends up with no knowledge of the User Control and therefore cannot track its data (or changes).
I want to create a TableRow with a TextBox. I want when click a Button a TableRow add to asp:table. in Button_Click event code I can add a row by a TableRow & TableCell & TextBox Objects and with help a HiddenField. My problem is that: after add first row that has a textbox, next row doesn't add by click button. I think Controls delete after post back in server and first textbox delete and new textbox add same position. what is solution after every click, a row with textbox add to the table?

I would like to be able to toggle all checkboxes in a tablerow base upon the value of the first checkbox.
If a user clicks on the checkbox at the beginning of the tablerow all other checkboxes in that same row need to get the same value.
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?
I have a composite user control consisting of three standard table cells (a legend, an image with a tool tip, and a text field control). If I add these to a TableRow in my aspx page it works fine and produces legal HTML in my source. The below works fine ...
<tr><MyControl:dataField
ID="txtEmail"
DataType="Email"
runat="server"
/></tr>
However when I try to do the same programmatically (C#) the TableRow won't accept anything in its Controls collection that isn't a TableCell. I could make my control a nested table in its own right but I lose the alignment of my form items on the page with multiple controls, as each table aligns itself according to its contents. Is there anyway I can make the TableRow accept my control as collection of cells or do I need to do some casting or making my user control inherit some kind of TableCell attributes? I can also dynamically add my controls to a TableCell item which actually displays OK in IE but creates illegal HTML (<td><td></td><td> ... </td></td> - I assume this is illegal) in my resulting source. The code below DOES NOT work ...
