I have an user control which contains a textbox.... I want to first display it false inside usercontrol and then visible it at the calling page.
note that the textbox id is generated dynamically.
i have a grid view with all columns as TemplateFields( No BoundField). Based on certain condition i have to set Visibility of few columns false. Suppose when there is no column 'CaseList2' in the DataTable, then the second column of the grid (whose column index is 1 )should be invisible. But when the Gridview binds it gives error DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'CaseList2'
i googled it and found that
GridView1.Columns[1].Visible = false;
should work. But its not working actualy.

I have a div in checkout.aspx page. The contents of div are as follows:
<div id="PaymentDetails" runat="server" style="text-align:center" visible="true">

I have a GridView with a load of data in, there is an ID associated to the data that I would not like to be visible to the users. All worked fine when all the cells were visible, but as soon as I change the ID DataBound column to false, when I try to access the item in code I get "" instead of it's actual value (that worked perfectly when it was visible).
View 2 RepliesI have a gridview that displays entries from a data table. I am giving users the ability to select a subset of the data in the table by having a textbox and search button in the grid view header. The search button fires the gridview row command, and changes the underlying sqlDataSource's select command, and adds the text value from the text box as a parameter.
Also, I have a "Show All" button in the header, that clears out the select parameters, so all entries in the table are shown. Again, this works perfectly.
What is NOT working is controlling the visibility of the "Show All" button control. Below is the html markup for the data grid header template:
<HeaderTemplate>
<asp:Button ID="btnShowAll" runat="server" CausesValidation="False" CommandName="ShowAll" Text="Show All" />
<asp:Button ID="btnSearch" runat="server" CausesValidation="True" CommandName="Search" Text="Search" ValidationGroup="vldSearch" /><br />
<asp:TextBox ID="txtSearchName" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="vldSearchName" runat="server" ErrorMessage="You have to provide an attorney name to search for." Text="*" ControlToValidate="txtSearchName" ValidationGroup="vldSearch" ForeColor="White"></asp:RequiredFieldValidator>
</HeaderTemplate>
In the Row Command event handler, here is how I am setting the visibility of the button:
If Not Me.dgAttorneys.HeaderRow Is Nothing Then
Dim btnShowAll As Button = Me.dgAttorneys.HeaderRow.FindControl("btnShowAll")
btnShowAll.Visible = Me.sqlAttorneys.SelectParameters.Count > 0
Trace.Write("Show all status is " & btnShowAll.Visible.ToString)
End If
The trace statement is showing the correct visible status - if the "show all" button is clicked, I do a SelectParameters.Clear() on the sqlAttorneys sqlDataSource.
Is my problem due to a misunderstanding of how the "FindControl" method works - I had assumed my new btnShowAll that I define is actually a reference to the "physical" control on the aspx page, so any changes I make to my local object is reflected in the control on the page.
If this is not the case, what is the best way to get a reference to the button control in the header row of the grid view?
I have a validator that check an input.
i what that the validator displayed "valid" if the value is valid, and "invalid" if the value is hasnt passed the validation.
can manage without adding an additional label for the valid state(by setting the visibility: true/false)?
does the validator control has am alternative value, or i have to override it?

View 1 RepliesFirst off - has any recent .NET / Windows Service Pack / Windows Update changed the behaviour around the Visibility of Panels / User Controls? An area of our site has all of a sudden stopped working. The most recent change that I made was a few weeks ago, I've backed out the change from my development environment, but the issue is still happening.
I'll explain what is happening. I have a couple of forms where the same behaviour is happening, but they follow the same pattern:
On the form there is let's say 2 ASP:Panel controls. In each of these there is a separate ASP:UserControl. When the User first visits the page, they are shown the first Panel and User Control. On this control they complete a couple of steps and click Next. This fires an event on the main page, which hides the first panel and shows the second panel, at least that is what is supposed to happen - and if I debug and step into the code this is what is happening as normal. Except on screen, the first panel is no longer being hidden, so it would appear clicking the Next button does nothing.
I'm at a loss as to what has happening - nothing has changed, and stepping through the code it's working correctly, but the screen is not reflecting what is happening in the code.
My next step is to create an isolated set of test pages to recreate the issue. Will attach when done and investigated, hopefully this will solve it
similar topic to what i posted yesterday ttp://forums.asp.net/t/1580413.aspxBut what I'd like to do, is click a label, hide this label but enable another label (which has a color background) for this I have the following code - but ASP.NET doesn't like the 'click' handling function????Can someone please point me in the correct direction to acheieve this please?

View 6 RepliesI would like to programmatically hide/unhide Individual Menu items.
How is this best accomplished. I see that intellisense does not have a visibility attribute for Menu1.Items(1).
One task that I would like to make a lot easier, is to be able to toggle a control's visibility to off/false if a particular database field is null. Is there an expression I can put in the visibility='<%# %>' part of my code that could handle this?
IsDBNull(DataBinder.Eval(Container.DataItem, "expLeaflets")
I have developed my application using Visual Web Developer 2008 express with Visual Basic code.
If I am working with 2 textboxs on a form, and I set the "Autopostback" to "true" for the first texbox then on the "changed" event, I can just add code to set the visibility to "true or "false" for the second textbox - it works fine. However, I do not seem to be able to figure out how to do the same thing when I am using a Dataview.
I have a table called "Customer" that contains 4 fields "CustomerName", "BasePrice", "LevelOfActivity", and "Discount".
My user enters information into this table using a Dataview form that displays the 4 fields.
When the user enters the value "L" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "false" - (I want to hide the field as this customer should not get a discount). If the user enters the value "H" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "true" - (I want to show the field so the user can enter the "Discount").
I have a checkbox in a formview in "edit" mode. I want the check to fire an event and toggle a different command imagebutton based on the state of the checkbox. It doesn't seem to be working.

How to check the field value which is assigned to the text box is empty or not.
I need to set the visibility of the text box to false when the field value is empty.
I have Table named PRODUCTS , that have 4 column productid, productprice,productname & discount( type numeric(18,0)) .. i am using datalist with itemtemplate that have 4 label to display all ..
I am binding datalist on pageload, now i want that Label4 with "discount" should only visible for those product that have discount , otherwise it remains hidden,
Problem in my code is that when i run it , label becomes invisible for all products whether they have discount or not. Here is my code i am using for it:
ds1 is my dataset
foreach (DataListItem item in DataList1.Items) {
for (int i = 0; i <= ds1.Rows.Count - 1; i++) {
double[] arr = new double[ds1.Rows.Count];
double temp = double.Parse(ds1.Rows[i]["discount"].ToString());
arr[i] = temp;
Label lbl = item.FindControl("Label4") as Label;
if (arr[i] == 0)
lbl.Visible=false;
} }
I have a Menu control in MasterPage based on web.sitemap file. My website has roles enabled (AspNetWindowsTokenRoleProvider) and uses Windows authentication mode. So, user has to be in a specific Windows Group to be able to access the site. I need to allow some users to see all menu nodes and some restricted set of nodes. How do I do that?
I would like to be able to create, say following Windows groups:
domain_namemy_app_users
domain_namemy_app_superusers
domain_namemy_app_admins
and code sitemap nodes this way:
<siteMapNode url="~/MOC_Masterdata_MOC_Approvers_Plain.aspx" title="MOC Approvers" description="MOC Approvers" />
I have a formview that displays user info from a dropdownlist. One account may have many users, but one account Primary. I am trying to disable the Edit/Delete button in the formview if the selected ID is the account primary. The problem I get is this.
Step 1: page_load - the primary user is displayed by default, but the delete button is enabled - not right
Step 2: I use the dropdownlist to select another user (not the primary) - everything's fine
Step 3: I then select the Primary User, the Delete Button is disabled - perfect
Step 4: select another user, delete button still disabled - Not right.
[Code]....
1. As you can see my sqlSelect Parameters are bound to the DropDownList.SelectedValue, but is t seems like my if statement for comparing selecteduser to varAdminID doesn't work except once.
So to help debug, i added a label control that displays the selected userID, but on page load the label is blank. but it displays the first record on the list anyway. so if this is the reason for not disabling the delete button on page load then why later does it not reable the button when the user is not the primary, and the UserID is displayed on the label and it is not the primary userid?
[Code]....
and im not getting the result i expected =
