I have a list view with a label that shows "Step #x", another label with the instructions, and then 2 linkbuttons for editing or deleting. At the footer of the ListView is another button "Add New Step" which opens up an empty TextBox and two buttons to save and cancel. I would also like it to increment the label, but I can seem to find the control in the code behind to change it's text. How do I do this?
While running ItemDetabound upon load of a listivew, I am trying to access the text in a label of the LayoutTemplate of a different Listview. It works fine if I try access the same labels under the same names if they are in the same listview, but not if they are in a different one. It was working for a while, can't figure out what I changed, but now says that object doesn't exist.
Here is a perplexing issue I have not seen a good answer to on StackOverflow, although there a couple stabs at it... I have a situation where I'd like to do this:
<asp:Repeater ID="MyRepeater" runat="server" OnItemDataBound="MyRepeater_ItemDataBound"> <ItemTemplate> <li id="id?"> All the other stuff </li> </ItemTemplate> </asp:Repeater>
is how do I get the ID of my <li> elements to be id1, id2, id3, etc., based on the ItemIndex they are bound to? So far the most... er..."elegant" solution I've come up with is to replace the <li> with an asp:Literal and dump the <li...>' text. But that just feels... so wrong. And no, I'm not using ASP.NET 4.0, which I've read will provide this functionality.
Once the template is loaded and cast back to the TabHeader class, it's null. How can I load that control, set the properties, and use it as the template? Or is the only way to go about doing this to create a custom class?
I need to access the controls dynamically created template fields at run time in datagrid in post back event. Is there any way to retrieve the values in post back event? Or else give the ideas to acheive my requirement. I need to create no of rows and columns as text box as per user input. After fill the values to text box , i need to access the values in submit button.
I have a dropdownlist in EditItemTemplate and InsertItemTemplate which I want it to populate at the runtime while Inserting an item or Editing an item.
I am facing an issue regarding populating a dropdownlist dynamically while in Edit and Insert mode. There are 0 Records in my table and it shows "Empty Data message" in my Listview control. Even the ItemDataBound event does not fire. So I am not able to find the dropdownlist in that listview.
This is my Aspx code which shows only InsertItemTemplate and EditItemTemplate.
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.
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 ....
From what I can tell the listview doesn't have a header template. I'd like to be able to list and line up the column names with the data on my list view, but there doesn't seem to be a straightforward way to do this. If I put it in a table in the item template, it lines up like I want it, but it of course repeats which is what I don't want.
The listview's datasource is a datatable. lets say that data when presented looks like "SOME COMPANY NAME T4220" I only want to write to the screen "T4220" and trim off the stuff before it. How do I go about doing this?
I would like to change the listview template on a button click event. for example if your in edittemplate i would like to switch to ItemTemplate.i am trying to do this because im writing my own custom update function for the list view. so after i successfully update the row, it doesn't switch back to the default view.
In my edit template I want a dropdownlist containing a list of possible customers. The list is populated from a database table containing existing customers. If the main record has customer "XYZ", then I want that customer to be the default in the dropdown. I'm using VS 2008 and C# My markup for the dropdownlist is currently:
The dropdownlist is populated but the problem is it shows the first customer in the list. I don't want the user to have to rechoose customer if that is not what they are changing.
I am using the ItemDataBound event of a ListView to attach data for the different kind of templates I am using. Well, actually, want to use - I have not yet figured out how to know which template is coming in in the ItemDataBound event. I want to figure out if it is the edititemtemplate, insertitemplate, itemtemplate, etc. All these templates have different controls (edit and insert are the same though) and I need to set the controls contained in them.
In my listview object insert/edit template, I have two dropdownlists (category, subcategory). When a user selects a category (autopostback), I would like the subcategory dropdown to filter to only the those that match the categoryID from the category ddl. This seems to be complicated by the fact that it is in a listview object. I'm currently using a queryextender on the subcategory datasource, but I'm not sure how to apply the selectedvalue of the category to the queryextender. The subcategory just shows all items and is not filtered. How do you accomplish this?
I have a ListView Which displays Customer, product, price, Quantity and comments from database.The User can either edit it or Insert new items. In Edit Item template and Insert item template, i need to add a image button next to the textbox, which when clicked, will display a pop up window with list of customers or products.I have been doing it with the normal aspx page with textboxes. I use click handler to pop up the windows.i'm not able to do with listview Please help to give a solution to it.How else can i add an image icon and click it and get the values back to the textboxes?i will post what i'm doing without listview first and then the part of the relavant code of Listview.
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?
I am trying to do this with many issues of data binding doubling the amount and not setting selectedValue on dropdownlist. I have read some posts and they help but I am missing a crucial piece. My problem is that my dropdownlist is doubling the amount of records for the dropdownlist. Instead of "YES;NO;SELECT A VALUE", I am getting "YES;NO;SELECT A VALUE;YES;NO;YES;NO". My database is correct with the UPDATE part but the rebind after update is failing horribly.
Background: I'm populating lots of asp.net c# GridViews and ListViews from a database and subsequently users may export them to Excel. I want export as native Excel (not html). I can't use office automation, and I'm using JET which works fine. I have no control over users' machines. Question: When doing the export, you have to tell Jet what type each field is, in my case "text" (varchar) or "numeric" (double). The difference is that if you export a numeric column, the users can sum the data in Excel, where as strings are exported with a leading apostrophe and so are not much use in arithmetic.
Currently I parse the first data row of the Grid/ListView, check if each value is numeric or text, and assign a type to the column accordingly. That works, except for when I have something in the first column which looks numeric but in fact is a text string. I don't want to parse every row in order to be sure I have the correct data type as some of these exports are quite large. When I load the Grid/ListView from the database, the database certainly knows what type each field is. So my question is... how do I extract the type of the database item behind a a Grid/ListView item? I could explicitly code it as an attribute on the item, but that's duplicating information I already have, if only I can get to it. I know that where I have a DataTable then I can get the underlying type from that, but mostly I don't have tables handy, just the Grid/ListView. Note that Jet will throw if you try to insert an empty string into a nullable numeric column. The way to do this is to omit that column name from the insert statement, or output a zero.
