Forms Data Controls :: PreRender Content In ListView Missing In Excel Extract?

Jan 13, 2010

Whenever I try to export a ListView with formatting or dynamic content in the PreRender event to an Excel file, I lose all of the changes from the PreRender event. Here's the ListView code:

<asp:ListView ID="ListView1" DataSourceID="profileData" runat="server" DataKeyNames="ROW_NUM">
<LayoutTemplate>
<table cellspacing="0">
<thead>

[Code]....

I've done some reading and found that RenderControl possibly ignores anything in PreRender for a control, but I'm thinking there has to be a way to get those PreRender changes in there before extracting the ListView to Excel.

The only workaround I've found so far is to copy and paste all of my preRender code into the Page_Load, and then everything looks fine in Excel. However, then I have to duplicate my code, as I still need it in the preRender event to display it on the screen properly. I don't want to maintain the code twice.

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?

Forms Data Controls :: Listview & Missing Vbcrlf's?

Jul 31, 2010

I had an excel data I converted to an access database. I did some vba to insert vbcrlf's into the excel and re-converted the data to access. It seems as if it did convert over until I printed on screen cell contents into a message box.So, I'm 100% sure my data has the cr & lf's but in my asp.net application's listview control they are not being rendered. I used easyfrom to convert from access to mysql.The application works fine except all the data is clumped together.

Forms Data Controls :: Export To Excel Missing Some Records?

Apr 22, 2010

I've programmatically generated an ASP.NET Table that is then added to a page. There is also a Button on the same page where a user can export the Table data into Excel. Very standard stuff. The data that is displayed on the page is correct but after exporting 10 rows are missing. I've checked encoding. I've compared character input: nothing unusual. Has anyone ran into this before?Here's the export code (see comment at the table...)

protected void btnExport_Click(object sender, EventArgs e)
{
string attachment = "attachment; filename=Abstracts.xls";

Forms Data Controls :: DetailsView - PreRender Event Bug?

Mar 7, 2010

I have a DetailsView on my page, bounded throught ObjectDS (but I think it's not important). Some field is readonly for some users - based on role membership and other paramaters. I've tried to use the PreRender event to manage these field's readonly state. Everything is working - except one template field: when I click first time on Edit button the dropdown list stay readonly independently the role membership. When I click on Cancel than Edit again the control state is good. Code of PreRender event handler:

Forms Data Controls :: PreRender Takes Upto 13 Seconds?

Jan 8, 2010

At the first loading of my page, duration of PreRender takes upto 13 seconds. That page has basically a gridview control which bind to SqlServer query by SqlDataSource. When I execute query seperately, it takes only 0.02 second.

On the other hand, for the next loadings of same page by postback, duration of PreRender varies from 0.5 second to 3-4 seconds.

In addition to gridview, there are several dropdownlist, update panel, ImageButton in gridview. I use paging for Gridview.

Which strategy should i follow to increase performance of this page?

Extract / Convert Information From A Listview To A DataTable?

Jan 4, 2010

I have a relatively simple Listview that suddenly needs (due to new requirements) to have it's 'layout' extracted to a DataTable so that a common routine can convert it to an Excel spreadsheet for export purposes.

The ItemTemplate is just a series of Table Rows with some text, data-bound labels and textboxes with validators in the cells.

Usually, when trying to pull out a particular value (like what was entered into a text box), I use the ListViewItem's .FindControl method.

For Each objItem As ListViewItem In lvwOptions.Items
Dim objTextHrsLabor As TextBox = CType(objItem.FindControl("txtHrsOptByLabor"), TextBox)
decHours = CDec(objTextHrsLabor.Text)
Next

In this case, however, I'm trying to take all the data displayed - all the 'rows and columns' of the table that was created.

Inside the ForEach / Next loop of ListViewItems, I started a ForEach/Next loop of Controls for each instance's controls but I got some really strange results returned (like controls that had a couple of table cells in them).

I get the sense I'm headed in the wrong direction. All I want is for the nicely-formatted 5-line, 6 column table to be converted to a 5-line, 6-column data table.

Forms Data Controls :: How To Push Down Outer ListView From Nested ListView Control

Mar 13, 2011

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?

Forms Data Controls :: Referencing A Nested ListView In A ListView?

Aug 17, 2010

Ok, background first:

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.
