Can Someone explain why this doesn't work here, when it works in another formview?
[Code]....
I Get Object Reference Not Set, but its all there. I see no reason why it shouldn't work. Same error happens if i remove the first if statement and leave the second it Gives an error on LocationAddButton.Visible = false;
I have a simple FormView (fvDespatchPart) which updates the status of an order and it's despatch date; the despatch date being retrieved from a textbox (txtRentalDespatchDate)
held within the FormView. The FormView's DefaultMode is set to Edit.
I have been trying to set the default entry for txtRentalDespatchDate to today's date in the code behind, using:
Dim dtNow As Date = Today()
Dim txtRentalDespatchDate As Webcontrols.Textbox = fvDespatchPart.FindControl("txtRentalDespatchDate") [code].....
I have had no trouble doing this in the past with FormViews whose default mode is set to Insert or Item, but in Edit mode it just does not seem to want to co-operate. I have read a few help posts, and have tried:
Putting that code in LoadComplete, PreRender, PreRenderComplete Page events, as well as the FormView's databound event. I've also tried nesting it within a ...
If fvDespatchPart.CurrentMode = FormViewMode.Edit Then
End If
... just to make sure if is in the right mode.
Nothing yet has resulted in anything but the same old error.
In my Application, I am using User control which contains one GridView and few Buttons. GridView Contains CheckBox in Item Template of first Column for Selection purpose. Now on one of the Button's click Event I am traversing through the GridView and find which row is selected.
Following is my Code for traversing which is not working:
foreach (GridViewRow row in gvCallSheet.Rows)
am working with form view for the first time.My issue here is i have an insert item template and edititem template where i have dropdownlist to insert and edit data in to databasemy code below

DataSourceID="ods_ChildPhysicalActivite"
onitemcommand="fv_ChildPhysicalActivites_ItemCommand"

I have a formview and data source that opens in the edit template and allows the user to update a few free form text fields. I also have some drop down boxes that allow a DOB to be built and populate another text box. All of this was working fine yesterday, and today somehow I hosed it and can not find the cause. I have rebuilt this page three times to get it working again, but I can't figure out what I am doing wrong to break it.

Here is the DataSource....

I'm having a problem with a FormView control that I have bound to an ObjectDataSource. The problem is that the FormView control is not automatically filled in with the public properties of the object linked by an ObjectDataSource control when I select refresh schema. Everything compiles and I can add fields manually, but there are a lot of properties in the class and I do not want to deal with adding all the fields by hand. It's not the end of the world of course if I have to add them manually, but I'm bothered more by the fact that it doesn't act the other formviews.
Has anyone ever experienced a problem like this? I have other objectdatasource controls with other formviews that properly refresh their schemas. I noticed that in the objectdatasource control that is giving me problems, the DataObjectTypeName field is not automatically set as it is in the others. However, after adding it manually it still doesn't refresh the schema. I'm using Visual Studio 2010. Defined in .aspx page:

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?
Two text boxes on a formview need to be prefilled with data (coming from session variables) on page load. The formview is in Insert mode by default. Is that the reason why it shows blank fields...
How do I get two fields filled in with data on page load.. the user will enter the rest of the fields and Click on Insert.
[Code]....
I put break points and saw that the data was coming in as expected...but when the page loads with formview, the text boxes do not show any data.
I was able to get the formview bound to the objectdatasource, it works great for the first record, but when i select the next record it gives me error below is all my code, if there is something else that i need to post .

View 2 RepliesI have a Gridview and when the edit button is clicked the details of that row is displayed using a detailsview. While displaying, I need to find a control in detailsView, and then bind it with a Datasource. First of All I'm not sure about the event to be used but have used DetailsView1_DataBound. However, if I have to find the control using:
var control=(ControlType)DetailsView1.Findcontrol("ID");
Always returns null. May be I am not using the right event, and it couldn't find the control at that point.
I have a dynamic gridview in which i need to add textbox, checkbox, imgButton in the cell dynamically.
At the moment user click on the imbgutton, a click event fire and i need to capture the user input on the checkbox and textbox of the particular cell.

I have try gridview.Fincontrol but fail.
using the GridView FindControl.
What I've done is I've setup a Gridview with a datasource to show only 1 of the columns I need from the datasource, but I also have another ItemTemplate Column in which I have a dropdownlist with another datasource that I've bound to the dropdownlist.
What I need to do is have the dropdownlist show the selected one when compared to a id from datasource in the gridview.

View 5 Repliesthis is probably very simple but I'm tearing my hair out!I'm using the FindControl method to try and grab the text in a textbox inside a DetailsView Template Field and display it on a label. Here is my code:
[Code]....
The word text has a squiggle underneath though and it causes an error as "System.Web.UI.Control' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type 'System.Web.UI.Control' could be found (are you missing a using directive or an assembly reference?)". I know the problem is that I'm treating this Control as a TextBox when it isn't, it's a Control. So how do I get from Control to TextBox so I can take the String and use it in code?
I thought I had this all figured out, in fact the following is similar to another page I have that works, but dinged if I can see what is wrong with this.I have a FormView with the InsertItem Template as the default. I have a label "UserId" that is assigned the logged on user's userid on page load with:
LblUserID.Text = Membership.GetUser.ProviderUserKey.ToString , which I am certain works.
There is a textbox "User_IDTextbox" within the InsertItem Template of a FormView, and I am trying to write the UserID into that text box using this VB code in a subroutine:
Dim TxtBxUserIDParent As TextBox = DirectCast(FVAddTradeResort.FindControl("User_IDTextbox"), TextBox)
TxtBxUserIDParent.Text = LblUserID.Text
This does not result in populating the textbox within the InsertItem Template of the Formview template with the UserID
