Forms Data Controls :: FormView Doesn't Work In InsertMode Or EditMode
Mar 29, 2011
by default, my formview loads up to Editmode and it looks like this:
My Page_load looks like this:
Problem is if binding is not ran during postback here, buttons on the ItemInsert mode DO work, but the button on the ItemEdit mode DON'T work. However, if I don't bind the fv1 here during postback, controls will not load on the formview ItemEdit mode and databinding will not occur.
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 want to preset the value of a textbox within a databound formview. Tried it within codebehind on onModeChanging and onItemInserting. Method onModeChanging was fired but the textbox.text shows not the expected text. Method onItemInserting was not fired at all.
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
... just to make sure if is in the right mode.
Nothing yet has resulted in anything but the same old error.
I have a Listview showing my data from the DB.And i have a Formview in INSERTMODE.I added a linkbutton the my Listview, in order to EDIT the data.How could i use the same Formview to Edit the item ? Will i have to change the DEFAULTMODE ? And how can i pass the Id to it ? Will i have to alter the SELECT COMMAND aswell to that it gets the querystring "ID" ?
Buying books, googling, reading these and other forums. I should have gone through beginners before jumping into advanced, so please forgive the question if it is an obvious error (which I am sure it must be).I have a list bod whic has a list of roads in it. The user selects a road (and since I dont know how to just make a selection send to the formview by clicking on a road in the listbox, the user then must click on a SUBMIT buttonave 2 different surface types, you are either hauling on aggregate roads or bituminous roads - but most hauls will only have one surface type.I followed the instructions for doing my listview edit/update/insert/delete from (http://basgun.wordpress.com/2007/12/29/listview-control-in-aspnet-35-4/)
What does work: I do see the right info if the formview is shown but when I click on the Update button it just doesnt fire the corresponding itemupdating event.
Can someone see what is wrong or missing?
What do I want to archieve: Just update the subscription's credits and its type: Upgrade, Prolong.
New finding: I added 'onitemcommand="fvSubscriptionEdit_ItemCommand"' to the formview and a corresponding event method with a simple code that throw a exception(just testing) but it doesnt enter the method but does whine when the method is missing. So why does it whine if the method is not there but doesnt enter the method if it does exist? I presume that this is the same problem.
I placed one FormView and one GridView conrtrols on the same page with one linqdatasource that is connected to both controls via their DataSourceID properties. While the GridView works without any problem (on updating) the FormView doesn't update the record.I traced the FormView events and found that in FormView1_ItemUpdating the argument e.NewVaues.Count = 0 as well as e.OldVaues. Count (also zero). Getting items from e.NewValues[index] or [key] causes an obvious exception. However, all the bound contolsn this wa
I've got in a gridview with two EditItemTemplate, which are dropdownlist. for the fisrt one I need autopostback because it's used in the second.So to bind the second dropdownlist, I'm useing the GridView1_ItemUpdating, but it doesn't work. It never goes into this funktion and so on updating the column with the second dropdownlist has Null values.What's wrong?That's my code:
i have a gridview that binds data after changes were made (delete,update..) and it's all done with the c# method DataBind() and i don't know why FF shows the changes but in IE8 the grid remains the same and only if i navigate back and refresh, then i see the changes.
I am making checkbox in datagrid, no matter what I try, I cannot get the right result from checkbox. Even I check or not check the checkbox, the result is false. It is like somehow the result is always the default value of the checkbox.
I have a gridview connected to my objectdatasource, i wrote a class for the database queries.Now when i do an update of record i get the id form the grid, when i click on delete i don't get the id, its 0.Is there an option to set the id? i can't find it in the gridview.
I have a listview and inside the listview I have a gridview. I'm binding data to the listview, then on the listview itemdatabound I'm binding the gridview. I want to make the gridview editable so I have an edit template and an edit command button. I have the event rowediting and inside there I set the edit index. Now normally I rebind the control and everything works. But if I rebind this gridview, nothing happens.
I can trace through the rowediting and everything is working. It's setting the edit index, it goes through the databind and gets the right data and binds it to the control. What is happening? Why isn't my rebound edit mode gridview showing up?
I'm using a Gridview in VS2008 framework 2.0 to edit a field with standard edit/save/cancel buttons on each row. I have a textbox named TextBox1 in an EditItemTemplate tag, it's value is binded to my field with '<%#Bind("LOGIN_NM")%>'. This is a simple form a took from an old project. My problem is when I try to read the textbox in the GridView1_RowUpdating event, it keeps returning the original value and not the modified value. I spent some time figuring the cells, controls and all so I'm sure I'm reading the right textbox, I have only one. I also tried using:
CType(row.FindControl("TextBox1"), TextBox).Text but I can't get the modified text to store in the database. The exact same thing works in the old project.
No matter how I set the width in the EmptyDataRowStyle in a GridView, it gets ignored. The width of this construct always takes on the width of the text instead of what is asigned to the width property. This is also true if the property is set as a CSS style width.
If the width is assigned to the GridView construct then the EmptyDataRowStyle will take on that width.
Im using File Upload Control in every row of a GridView.... Like tis
