Forms Data Controls :: Editmode On GridView Inside Of ListView
Aug 31, 2010
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 have a Gridview that shows my data, I allowed it to have Editing and Sorting. I have achieved refreshing my GV with <META HTTP-EQUIV="Refresh" CONTENT="15">. however, when I Edit and it hits the time to refresh, I loose the Edit mode and starts at the beginning of the grid (I need to find the data again.) Is it possible to still have the refresh (15secs) then when Iam in EditMode, the Refresh stops, then after I have clicked UPDATE. the refresh time starts to count again. (i use VB)

I don't know how to do this, I think I need to find the control first.

I've been working with ListView for a long time, but I haven't been using it's built-in events so far. Now I was trying and was stuck. Until I moved both LinqDataSource and ListView to another page, without a master page.
Then it worked. Same happened with GridView as well.
I do not use Update Panel. Just master page. And if I use manual methods for edit, insert, delete then it doesn't fire OnItemCommand.
Is there a known uncompatibility with databound controls and master pages? Because I couldn't find anything about it on Google.

I have a checkbox placed inside a gridview:
<GridView><asp:TemplateField HeaderText="Driver"> <ItemTemplate> <asp:CheckBox ID="CheckBoxDriver" AutoPostBack="true" OnCheckedChanged="GridView_Persons_SelectedIndexChanged" ValidationGroup='<%# Eval("ID") + "-" +((GridViewRow)Container).RowIndex %>' CssClass="CXDriver" runat="server" Checked='false' /> </ItemTemplate> </GridView>
For example: A listViewItem 1 has 3 drivers are checked, A listViewItem 2 has 2 drivers are checked.
Therefore, if changing the selectedIndex of the list, the checkbox indexChanged event will be fired.
How could I disable the autopostback of the checkbox during the listview item changed.

I have a class
public class MyClass
{
public int id {get; set;}
public string name {get; set;}
}
I store objects of type MyClass in list: List<MyClass> listOfObjects {get; set;}
I want user to edit data. To display data I am using ListView control - I am binding listOfObject list to ListView:
<asp:ListView runat="server" ID="ListView1">
<LayoutTemplate>
<table runat="server" id="table1" >[code].....
So far so good, and everything works fine. I see the data in ListView.I do not know how I can edit data in ListView without entering EditMode - I do not have Edit button, I have only textboxes to enter new data.All I want is to bind data edited in textboxes in the opposite direction - into listOfObject list. I have tried many solutions and nothing was working correctly...
I thought that I can read data this way:
var listItems = ListView1.Items.Cast<ListViewDataItem>().Select(a => new MyClass
{
id = ((TextBox)a.FindControl("tb1")).Text,
name = ((TextBox)a.FindControl("tb2")).Text
}).ToList<>();
but with this I get data which were in textbox before editing..., how to make it working(maybe it would be better to use ObjectDataSource?)

I have the following (abbreviated) code:
<asp:FormView ID="FormView1" runat="server" DataKeyNames="ItemID" DataSourceID="LinqDataSource1">
<EditItemTemplate>
<asp:DropDownList ID="ddlCategory" runat="server" SelectedValue='<%# Eval("Category") %>'
DataSource="<%# GetCategories() %>" DataTextField="Text" DataValueField="Value" />
</EditItemTemplate>
<ItemTemplate>
<asp:ListView ID="lvParticipants" runat="server" DataSource='<%# Eval("Participants") %>' >
<InsertItemTemplate>
<asp:DropDownList ID="ddlCountry" runat="server" SelectedValue='<%# Eval("Country") %>'
DataSource="<%# GetCountries() %>" DataTextField="Text" DataValueField="Value" />
</InsertItemTemplate>
</asp:ListView>
<ItemTemplate>
</asp:FormView>
When the FormView is in Edit mode, ddlCategory is populated as expected by calling GetCategories(), which returns a List of categories. However, when the ListView is in Insert mode, ddlCountry is empty. I put a break point in GetCountries(), but it never gets called. If I change the name of the method, I get an error. So it recognizes the method at compile time, but does not call it at run time. I'm guessing this is an embedded binding issue of some kind, but I'm hoping someone can save me a lot of time by pointing out the solution.

I am loading the autocomplete extender properly but I need the PK from the selectedValue. I have looked at other examples and they do NOT show how to drill into the tabcontainer, then drill into the listview, and then locate the extender value. Here is what I have so far. My "TABCONTAINER" value shows the extender correctly but I am unable to locate it.

I have a listview that is showing its result by using a linq query. The linq query goes like this.
[Code]....
* db.Varer: Varer is a table that contains basic product information like proudct name, product nr. etc. ** a.fk_kategori_id == CatParamId : I'm just saying limit the result according to the Category ID (a.fk_kategori_id). The category id is coming from a dropdownlist (CatParamID) *** Join: Besides the Varer (Product) table I also have another table, Sizes. This Sizes table contains 6 columns (ID_Sizes (int) primary key and the columns: OneSize, S, M, L, XL, XXL all are bit (true or false)). There is a relationship between Varer table and Sizes table. It says that I can only insert a value into the "fk_sizes_id - column" of varer table if that value already exists as primary key within the Sizes table. **** I'm starting by picking basic product values like productId, ProductName etc from the Varer (a) table ***** Then I'm picking the corresponding Sizes values (onesize, s, m, ...) from the Sizes table. Now within my ListView I'm showing the above result by using Eval, like this.
[Code]....
And this works perfectly, but now comes the thing that is causing me trouble. I have the below drop down list (still within the ListView ItemTemplate):
[Code]....
I want this drop down list to be populated with only those of the "linq query's Sizes table result" that are true. By "Sizes table result" I mean these

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.

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'm trying to do a validation for checkboxlist on a server side as all java approaches didn't work. However, probably due to the checklistbox is inside a listview the FindControl is empty. how to find a control inside a listview on a button click event when the button is outside of the listview.
<asp:CustomValidator
ID="rfchblAnswers"
runat="server"
ErrorMessage="* Please, select at least a one checkbox."
OnServerValidate="cblCustomValidator"
EnableClientScript="false"
ValidationGroup="EnterData"
Display=
"Dynamic" />
Public
Sub cblCustomValidator(ByVal objSource
As Object,
ByVal objArgs As ServerValidateEventArgs)
Dim chblAnswers As CheckBoxList = _
CType(lv_qstns.FindControl("chblAnswers"), CheckBoxList)
If CType(lv_qstns.FindControl("chblAnswers"), CheckBoxList)
IsNot Nothing
Then 'it's not working here as it cannot find the control inside a listview
Dim boolFlag As
Boolean = False
For Each li
As ListItem In chblAnswers.Items
If li.Selected Then
boolFlag = True
End If
Next
If boolFlag Then
objArgs.IsValid = True
Else
objArgs.IsValid = False
End If
End If
End Sub

I have a ListView showing just a list of concatenated strings obtained from different field of the objects of the datasource.
A LinkButton (with CommandName="Edit") in each row Event handlers for OnItemDataBound and OnItemEditing
A UserControl in EditTemplate.
Now the problem is, I don't know how to use Bind expression in the UserControl. I mean, how to populate this usercontrol when the linkbutton is clicked? (I tried capturing the control in theOnItemEditing handler. But FindControl returned null, as that handler is called before going to edit mode.)
