Forms Data Controls :: Unhiding Control In FormView Based On Another Control's Value?
Feb 8, 2010
I am attempting to show/hide a control (txtInpatientType) when a user views individual records on a FormView (frmData) depending on the value stored in another control (txtPatientType). For example, if txtPatientType.Text = "Inpatient" then txtInpatientType.Visible needs to be True. Very simple code follows.
[Code]....
txtPatietType and txtInpatientType are both ReadOnly. txtInpatientType.Visible = false by default.
i have the following scenario: one formview. when in editmode there is a child formview linked to the other by a column value. i need to take the value of one of the values of parent formview controls and set it to a textbox of child formview in insert mode. I wish to know which event should I use in codebehind to bind both controls? (that escenario will have paging and must keep the binding as if it was master detail)
I am using a form view control which has two binded textbox. Now at this level it works fine and the textboxes show the values from database. But when i insert a panel inside the form view and move these two textboxes inside the panel, they dont show any values. What could be the reason for this?
I have a formview with an insert item template. I have added two dropdown controls that are databound to two different database tables to this insert template. However, when I click the 'InsertQuery' for the Accessdatasource neither of these controls are available as 'Parameter source options'.Out of interest, if I take these dropdown controls out of the formview and put them on the page they then become available to use.
I have a calendar control where a user selects a date and then inputs info into a FormView control. Underneath the FormView is a GridView that shows all data from the SelectedDate on the calendar control. However, when the date is selected, all the information from the table ( from all dates ) is displayed.

i'm trying to develop a ASP.Net control. If it based on System.Web.UI.Control id doesn't work correctly with Ajax.Net updatePanel. If I change it to System.Web.UI.WebControls.WebControl the it works fine with Ajax controls. What is the difference between them and how I implement it on Control based Control?
I use a GridView control to select the row to display within the FormView. The FormView contains a RadioButtonList to facilitate the selection of one of its values. My C# codebehind contains a "selected_index changed event to grab the values from any of the modified FormView controls. My problem is that it is not picking up the selected radio button. Here's some code:
I have a dropdown in the InsertItemTemplate of a FormView that I need to add code to it's SelectedIndexChanged property, however I can't seem to find any way to do this.
For example, if the dropdown was not in the FormView I would simply use...
[Code]....
...but because it's inside the FormView I can't use the above.
Couple quick questions:What's the difference between FormView1_ItemUpdating and FormView1_OnUpdating? Do they occur at different times in the update process?Still can't get my code to upload the file...what am I missing?
Instead of usng FormView with SQLDataSource control, I like to use it with LINQ-to-SQL. For example, can I write my own LINQ to SQL for Edit and Update? Will FormView control work in this way?
I've been searching on this question for hours and not finding a solutionI simply want to access a FileUpload control in the EditItemTemplate of a FormView.When the FileUpload control is outside of the FormView, I can access it like this:
[Code]....
Visual Studio says:"The name 'UploadImage1' does not exist in the current context" It says this about any controls I've put in the FormView.How do I access these controls in my c# code behind?
I have a textbox in Formview inserttemplate and I want it be invisible on click of a button.In Visual Studio the intelligensense for this textbox does not show up at all - meaning it is not accessible. However, the control eg textbox OUTSIDE the Formview is accessible.How to modify the code so that we can modify property of a textbox WITHIN inserttemplate WITHIN the formview ?
How would I go about populating a textbox within a FormView with the SelectedValue of a GridView? I'd like to know how to do this with the GridView on the same page as the FormView or a GridView passing a parameter from another page.
I am doing a library application. I am using a formview control to display and edit the details of an existing borrower.
What I wish to do is to allow the user to enter the borrower barcode into a textbox and select the details of the borrower corresponding to the barcode.
At present I have kept the textbox and a button outside the formview. Once the user enters the barcode in the texbox and clicks the button, the data is displayed in the formview control.
Now, my doubt is that is there a way to keep the textbox inside the formview control itself and use the value(Which should be user input) for selecting the details?
I want to add some functionality into a formview when it is in its "editable" state. I want to have a check box and if a user clicks the checkbox then it makes certain text areas and labels appear inside a table. Seems straightforward except that I am not sure how to access a formview in a code behind and do it when its in the editable state and then I have the consideration of the ProfileDataSource which shouldn't matter because thats not part of manipulating the visual elements inside the Formview.
I have a Formview ('formview1') with a pager. I also have a gridview ('gridview1') linked to a SQL datasource ('History'). I need to set the SelectParameter ('Serial') of the datasource to be the value of a field on the current page in the formview. The value i need to get is in the ItemTemplate and is a label called 'SerialNumberLabel'. So, something like:
<SelectParameters> <asp:ControlParameter Text = "Eval fromview1.currentpage.itemtemplate.SerialNumberLabel" >
I also need to ensure that the SQL source and gridview rebind when the pager is activated.
How to write code in vb.net to control the Dropdown which is inside FormView EditItemTemplate. FormView named "frmFaultsReg" DetailsView named "lstStatus" Actually what i want to do that there is a textbox inside FormView EditItemTemplate and ItemTemplate to insert Closing date. lstStatus has a value PENDING and CLOSED. If a user select CLOSED from lstStatus then the date textbox named "ClrDateTimeTextBox" should show current date time and to insert into database and if user again selects PENDING from lstStatus then the date textbox should show empty. I think the postback of lstStatus should work but lstStatus is inside the FormView thats why I am unable to hook it.

I have a FormView and I want to set a default value from the database. I can't get it to bind to the value in the database. My FormView looks like this:
[Code]....
The EditItemTemplate does not even load when I click the edit button on my FormView control, but I don't get an error message either.
I've got a FormView control for which I'm Viewing, Inserting and Updating to a MS SQL Database.
Instead of adding a SqlDataSource control to the page, I've created it in the code behind and declaring the properties/attributes for it during Page_Load.
At the moment, everything is bound and working fine, but I'm having an issue Databinding to the child controls in my FormView with parameters set in the code behind.
This is where I'm at.

So, I need to be able to bind the DS.InsertParameters.Add("PageTitle", ---) with the txPageTitle control in the Insert Template, same with the PageURL to txPageURL. Is there any easy way to do this from the code behind? I can't seem to find a way to add a parameter without needing to assign it a value.
I have created a formview with 4 dynamic controls fields that LINQ to a database.

There's an event handle for each of the first three fields whenever a text change with following codes:
' extract textbox from both SubTotal and the modified field tboxSubtotal = FormViewAssistance2.FindControl("totalTextBoxEdit") tboxModifier = FormViewAssistance2.FindControl("foodTextBoxEdit") 'extract string from those textboxes txtSubtotal = tboxSubtotal.Text txtModifier = tboxModifier.Text 'convert text to double and add them together Double.TryParse(txtModifier, dblModifier) Double.TryParse(txtSubtotal, dblSubtotal) dblSubtotal = dblSubtotal + dblModifier 'post the changes back to SubTotalTextBoxEdit 'totalTextBoxEdit 'EditorPart.ReferenceEquals("totalTextBoxEdit", dblSubtotal) 'PostBackTrigger.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal) 'EditorZone.ReferenceEquals("SUBTOTRECTextBoxEdit", dblSubtotal)
I'm stuck on how to post/update totalTextBoxEdit to reflex changes in first three fields without having user clicking Update button to save the information into database. I've tried above 3 statements but none of them is working.
