Forms Data Controls :: ListView NewEditIndex Always Returns Zero 0?
Jan 6, 2010
I have a listview control on a page. Every item in the ItemTemplate has a LinkButton control with CommandName="Edit". When I click one of these links, the listview goes into edit mode. However, it only goes into edit mode for the first item on the list, because the NewEditIndex is always 0, regardless of which item I click on. I can click on the third item and the NewEditIndex will still be 0, so the first item will go into edit mode. Below is some code.
One selects items from the dropdown lists and click the Search button.
The ListView displays all the entries that match the criteria.
STEP 2:
Each entry in the ListView is clickable to select more details in the FormView.
Everything works perfectly well. However I'm testing the selected values after each postback based on the following script:
[Code]....
Now after STEP 1 (Search button) I get the selected ddl values. GREAT so far.
However in STEP 2 and in order to get the selected value of theListView I have to click twice on the same entry in the ListView. The ListView1.SelectedValue is returning 0 after the first click. The correct value is displayed after the second click.
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.

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) :

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 have a listview and a dropdownlist that is pulling from an SQLTable that I am using to insert data into the ListView, which is associated with the SQLTable. For the life of me I cannot figure out how to get this thing to not allow duplicate entries into the listview.
If I could get at the data that is inside the ListView I think my problem would be solved. At the moment all the code I have is to simply find if I can at least get the data down to something I can compare, from that step I will have no problem writing something functional, at least functional for my needs. I really could use a hand with this:
[Code]....
I don't personally have access to the SQLTable, but I can have somebody make changes if this should/needs to be done from that end, but I would rather do it from this end in VB. I've been digging through the MSDN Libraries
I am using a Gridview binded to a LinqDataSource that represents a database view. The gridview paging is enabled. When navigating from page 1 to page 2, it displays the right count of rows in this page (assume pagesize is 10 and page 2 should have 4 rows only to have total of 14 rows in the view; the datasource), however, it populates wrong data (from the previous page). On the contrary, when I disable paging, everything works ok.
I have a gridview. In the rowupdating event, the txtbox returns null. I have enabled viewstate for the gridview. But still it does not work. I have made this in Kentico.
Since I am not using a DataSourceId at the markup I am having to create my own Sorting handler. I found a sample on MSDN but the variable 'dataTable' always returns null why?
When i go to my detailsview itemtemplate, the checkbox returns the value correct, but every time i update it, it always returns 0.I'm using a MySQL db and the type of "grabbelpas" is tinyint(1).If more code is needed just ask. But my other textboxes are updated correctly, it's just the checkbox that doesnt update well.
I have in my code a gridview that I redirect to excel, it works fine when I have data in the data set. waht I want is to show column headers when there is no data right now what i get is empty sheet.
I am trying to populate the ListView using LinqDataSource data source but the issue I am having is.I need to load the listview on Search button click action.
IN the page_load I kept like this: =========================================== LinqDS.Selecting += new EventHandler<LinqDataSourceSelectEventArgs>(LinqDS_Selecting);
protected void LinqDS_Selecting(object sender, LinqDataSourceSelectEventArgs e) { e.Result = ObjectDS; } ============================================= This works fine but this happens on page load,i want this binding to happen on button click?is there a way to do this?
I am tryting to reach controls in the gridview rows by RowCommand event. I can take values of controls which are binded to gridview source successfully . But for all other controls which is not binded to gridview returns NULL value. All controls run at server. Why is that?
I have a store procedure that loops through items and returns multiple 1 row returns.The gridview will only show the first return, and no more because each return from the SP is labeled as row 1. Is there a way to change my SP or have gridview assign a new row number to the returns?My SP:
