I have an array that I need to display using a feature like listview. Is that possible? I need to be able to display a "temporary" list of information that the user may add or delete entries. Once they approve the list I will loop through the list and store the information in a table.
View 4 RepliesI 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'm new to asp.net, php had this function that could store sql date in an array, I can't find something similar in .net, so this is what I came up with so far.
Sub Compareid()
Dim queryString As String = "Select top 2 id from my_videos order by id desc"
using connection As New SqlConnection(ConfigurationSettings.AppSettings("sqlacct")

First time using a ListView control, I have it inside an UpdatePanel:
[Code]....
[Code]....
[Code]....
[Code]....
When the UpdatePanel Loads, it feeds the data to the ListView. Whenever the user clicks on a row in the ListView, a new window displaying a "note" pops up, the ItemDataBound event ties it all together. What I'm trying to do is add a button to each row so that the user can delete the row. This would call a Sql statement and then the row should disappear. I followed a couple of articles I found on ListView on how to do this, so I added a button called imgBtnDeleteNote (see markup above) and set the CommandName = "Delete", hoping that it would trigger the ItemCommand and ItemDeleting event (I have some bogus code in them, first I wanted to see if they would trigger).
The problem is that they don't seem to get triggered when I click on the delete button. All the rows in the listview disappear, and when I manually refresh the page they come back. My guess is that the events are not firing because I'm not using a DataSource object in the aspx code, but I'm not sure.
I want to compose data myself without using any DataSources. I want to display it in ListView. How to implement the DataPager to function properly? I tried implementing PagePropertiesChanged of ListView, but it doesn't work.

I am using a ListView and i want to get my datatables sorted by clicking table headers. I am binding my ListView to DataSet via DataSource peoperty of ListView.I donot want to use ObjectDataSource or SQLDataSource Controls.
View 2 Repliesi would like to sort a listview. i don't have a datasourceID. i bind the datasource manually. i think of using jquery(tablesorter) but i don't know how to use it.
View 1 RepliesI have a user control, named productslist.ascx. On pruductslist.ascx, I am using Entity Datasource and a QUERY EXTENDER and LISTview. I have a page Defualt.aspx. On Defualt.aspx, I have a TEXTBOX with a SUBMIT button for searching the site. Everthing works fine so far, AS LONG as the results of the Search is posted back to Default.aspx. What I want is for the results of the search to be posted on a different page.
So I created a new page, Results.aspx and set the postback url to it.
What I want is that when a user clicks the Submit button, after entering a search string, the text the entered is used to execute the query on Productslist.ascx and the results displayed on RESULTS.ASPX. Again, everything works fine as long as the results are posted on same page hosting the usercontrol, BUT I want the postback url to be a different page. I am coding in VB and VS 2010.
I have a listview which has a complicated Item template that contains a repeater, an objectdatasource and some other controls. On the first run I am only showing 10 Items of the listview. The user has an option to show 10 more ListView Items. If user clicks on show older items; the listview shall add another 10 items. how to go around this since my list view already has a datasource and I don't want to rebind the whole listview all over again. Instead; I just want to add another 10 items.
View 7 Repliesso instead of a datasource control, I have a Data Access class that I'm using to populate the ListviewI added a datapager and everything pretty much works until I hit the first or last button. Then, I get the following error: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/>Also, Something was mentioned about ClientScriptManager.RegisterForEventValidation - - couldnt' really find an implementationI tried setting:EnableEventValidation="false", but then, all I got was squirelly interaction with all the numbered links (sometimes having to double click them, etc) - no matter what I tried from there on out, even when I removed the enableEventValidation property altogether.
View 7 RepliesMy original code was in classic vb. and could use redim array to resize them. I was porting the code to c# now and lately i have run into an issue to resize a 2 dimensional array. The thing here is I have a 2 dimensional array whose 2nd dimension needs to be increased dynamically as needed to accommodate the data. For say
String[,] ary1=new String[2,10];
I'm doing some operation in a loop and filling in the data in ary1. And if the loop still continues, on reaching the ary1 upper bound i need to increase the size further to accommodate 10 more rows. I tried couple of ways to copy it to a bigger array and assign it back to the current array. but somehow dint work.
I'm using VS2008. When a dataset is bound to the DataSource of a ListView, SelectedIndexChanged event does not fire. If I used DataSourceID instead, it has no problem. But SelectedIndexChanging event fires for both.
why and how I can get SelectedIndexChanged event fired when DataSource is used?
I have a listivew that is assigned a datasource in the code behind based on query string options. From what i have found out, once there is no datasource assigned in listview html then the sort feature stops working automatically and you must put the code in the _Sorting event. I cannot find a good example of this logic.
good example of the listview manual sort logic?
I am working on setting up an aspx page using access datasource in web eepression. Access Datasource is having image source information from other resources feed. I am using listview to display all the images.
The problem I am facing is that all the images are displaying in different sizes. I tried to customize Layout template by specifying the td height and width but it's not working. Is there any way to autosize the pictures in listview once page is displayed.

View 6 RepliesI 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?
