Forms Data Controls :: ListView Not Recognizing ItemType Correctly?
Sep 20, 2010
I thought I finally had this cracked but now I want iterate through the records in my listview and do different things depending on whether the record is displaying existing data or is a blank, new record. Easy, right? Here's my code:
[Code]....
The problem is that the listview doesn't seem to recognize the insertitem as such. Obviously I don't really want that message box in there but it was just to test whether the insertitem was being picked up. The message box is never displayed.I also tried a simple iteration through the listview items with a message box popping up on each item displaying the item type. It said 'DataItem' every time, never 'InsertItem', even though there is definitely and insert item there!!
I have a ListView (table inside) and it's first row are some TextBoxes for filtering actions.
In the last column I have a button that calls my Search function and filters the records according to the inputs.
[Code]....
My Search function for now only displays a text inside a Label at the top of the page.
When I load the page, I'm using ListViewPesquisa.DataBind() so it shows it's EmptyDataTemplate, but when I click the button inside the event isn't called at all. If I do put some data (any data) in the ListView and it shows it's LayoutTemplate instead, the event is called properly.
I can get around this issue by moving the filter line out of the table, but I'd like to know why is that the button inside the EmptyDataTemplate doesn't work.
I have created an imageurl and label ids inside an itemtemplate which is inside a datalist but when I want to do some programming based off of those two ids, the code behind files do not recognize anything inside an item template.
Is there a way I can retrieve from an itemtemplate onto say like a string in a code behind file?
To make my explanation easier this is what I'm trying to do:
I have two div tags, one on the left and one on the right.
The div tag on the left contains a datalist of an Itemtemplate of various pictures.
When you click on one of these pictures, the same picture you clicked on will display in the right div but larger width and height.
I am using listview and datapager for display. I use two level of listview, where inner listview item can be 6 types. I use my own datasource. I only need to display 1 inner listviewitem per page. It display each page correctly, but page number is not set right, eg, when 2nd page (other as well) is click, 2nd page number is not disabled while 1st page number is still disabled. Here is the code:
I am simply trying to change the listView template based on a value in the listview data. I do have this displaying the information correctly. Except when I try to change the item template based on a value in the listview. My code is below ....
I have a ListView, I've setup to use an ObjectDataSource, I've created my Layout and Item templates, and I'm able pull and view a list of my data no problem. However I want to add delete capabilities to my ListView and my reference material tells me to go into the "Configure ListView..." option under the ListView's smart tag, the only problem is I don't have that option, the only three options in my smart tag are "Choose DataSource", "Configure DataSource..." and "Refresh Schema", what am I doing wrong?
I have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?
Does anyone have an example for how to create a Dynamically Templated Listview with prefernces page to specify which columns & column order)? Also the listview would also have Edit, delete and insert options if possible. And uses the n-tier approach with Bus Layer and does NOT use LINQ.
Is there any way to enable alternative ListView (LV2) or any other control in case when ListView (LV1) returns no records from DB? I already have emptydatatamplate designed for this case, but I need to enable a new ListView below in this particular case and I don't know how to achieve this!
I try to datbind a listview which is inside another listview InsertItemTemplate.
[Code]....
I'm binding the listivew in the parent listview onitemcreated events. I receive the error Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
I am having trouble finding how to solve the following issue :
I am using nested listviews to display Sales and Sales details.
The main ListView displays General Information about Sales and the child ListView displays the detailed information about one sale. the child listview is shown only when the user clicks on a link (see included code, DataBind is made on PageLoad) :
ASPX Markup Code :

C# Behind Code :

If I removed the datapager part, I can manage show/hide the child list view on the button click event. but if I want to use the DataPager with the PreRender event handling, the child listview is not longer shown on button click.
The form allows a user to create and edit one estimate.
Each estimate can contain multiple Jobs, which are represented in a ListView.
Each Job can contain multiple Parts, which are contained in a ListView that sits in each item of the Jobs ListView.
A user can add and remove as many Jobs as they want.
A user can add and remove as many Parts to/from each Job as they want.
I have no issues adding to each of these, but I do have a problem removing a single part from a single job.
For a reference, here is one Job in the Jobs ListView on the form:
I want to make sure that no matter what a user does, the part of the form they are working on saves what they have. Removing a row from that Parts ListView is no exception. What I want it to do is save the values in each of those textboxes and then delete the necessary row.
Here's what I have in the codebehind:
[Code]....
The EstimateRow variable I create does not get a value from theListView)HFERID.Parent.FindControl("LVEstimateRow") bit of code. There must be another level of nesting that I'm not accessing correctly, because it can't seem to find that nested ListView.
I have a datakey defined on my outermost ListView. When I click on a linkbutton in a row in this listview, the second listview is displayed. This inner listview has several controls and also a linkbutton. When I click this linkbutton, it gets handled by its own event; linkbutton_click. In this event all the data is collected from the innermost listviews' controls, and sends it to the database. The only thing I need within this event is the datakey from the outermost listview.
how to do this when the checkbox in listview layout template check select all checkboxes in listview itemtemplate.I dont give 'Eval 'field to checkbox present in itemtemplate.
I'm using a GridView to retrieve data from a stored procedure using a SQLDataSource (db is SQL Server 2008). When I compile my application and go to my website, all the data is loaded and shown fine. If I was to add a new entry to the table however (a seperate page on my website has a Wizard control to facilitate this) and then return to the page with the GridView, the new entry doesn't show up.
Looking from SQL Server, the data has been added, but the GridView isn't updating to show it. If I were to recompile the project with F6 and refresh the page, the new data will show up. I tried calling DataBind() on the GridView in the Page Load event, however the issue still remains.
I have a GridView in ASP.NET. I have an Edit CommandButton for every line in the GridView to edit the data on that line. All of this works fine except for the fact that when the user clicks on Update, it does not update with the correct value that the user entered. I have this as a Template field with the textbox to edit bound to the field, so it updates when the user changed the value and clicks Update. However it does not work. I have tried almost everything and its very frustrating. Here is the code for the Data Source:
<asp:SqlDataSource ID="Table1DataSource" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString2 %>" InsertCommand="INSERT INTO TABLE1(ProjectId, WBS, WBSTitle, VersionId) VALUES (@ProjectId, @WBS, @WBSTitle, @VersionId)" DeleteCommand="DELETE FROM TABLE1
I have problems with GridView control which has template field with checkbox in it. My primary concern is that same code works for all the other GridView controls I have in different webforms, but not in this one.
This code is supposed to get the identities (ID column in GridView) and then get the values of first two selected and finally redirect them to another webform as querystrings. I double checked the GridView and they are identical (except they are binded to different datasource).
I want to display a warning message and then open a panel on my form in response to a button click in my gridview.
I have used this on another form with a delete command in a gridview column and it work perfectly.
Why isn't it working with my select command ?
Here is the code:
<asp:LinkButton ID="LinkButton3" runat="server" CommandName="Select " OnClientClick = "return confirm='Are you sure that you want to delete this record ?');">Select</asp:LinkButton> </ItemTemplate> </asp:TemplateField>
have created a data table as global data table for the session. So when the user selects the drop down Address Type Main , Street, Emergency - I want the Address text fields to display based on user selects. So, for my dropdown i have datavaluefield column as addressid. And the datasource for this is datatable. I was having problems converting from datatable to dataview. Does anyone know how to do this? I was geting errors cant convert from datatable to dataview. I was choosing dataview because you have the filter option. But then I saw you could also select in data table. So I am trying to select a row in datatable with select with expression like this:
Dim dtAddress As New DataTable dtAddress = GlobalVariables.AddressTable
I have 2 gridview controls gathering data from 2 different tables and I want them to line up on the screen so they look like one big table.
Each table has the same number of columns but the 1st columns on each grid view don't line up. Both are set to 200px, all other columns are 40px. The data in one has say 5 letters in the 1st one and 25 letters in the second one.
Is there a setting I need to use to make each column 200px?
I have a GridView with a Template Field set to Checkbox. Issue is; when I click the asp:button I placed beneath the GridView to update the database, I do not get a checked value on the returned button. So it just skips my code and nothing happens.
[Code]....
Then I have my Method.
[Code]....
So when the code gets to this line if (cb != null && cb.Checked == true), the value is always False even for the checked box.
