View 6 RepliesHow to access lable control inside the EmptyDataTemplate in Listview while dataset is empty to show message?
View 6 RepliesI have the following setup, but i would like to make the empty text more specific, so just looking to have it display the same message but with the selected value text from the drop down as part of the messages.
so if you select say the 2nd item from the drop down, then i would like to have the empty label(if empty of course) display "There are No Records for Last 24 hrs"

All the writeups on ListView's EmptyDataTemplate say that it's for displaying the fact that no data records exist, which is logical; but the bad thing is that I've found nothing as a follow-up. In other words, I haven't been able to find any "now what?" once you (as the site user) find that there aren't any data records. I am led to then ask what the real purpose of the EmptyDataTemplate is if you can't do anything with it.
I added a button called "Add Your Photo" on the EmptyDataTemplate, which activates a ModalPopupExtender with an AsyncFileUpload. All this works fine in terms of uploading the file but nothing happens after that. I wonder if I should be starting instead in the InsertItemTemplate.
So, I need to know how to accomplish a couple of options: I need to start out in either the InsertItemTemplate or the EmptyDataTemplate. If I do the latter, I will need to know how to get from there to the ItemTemplate so the rendering can be displayed.
What code should I use to display the data--that is, how do I move from the EmptyDataTemplate to the ItemTemplate?
There have been a few datapaging questions tonight, but mine is a bit different..
I have a regular datapager, in a seperate project it seemed to work fine with the same query and templates, but when I use it in my page, whenever the I try to page I get the emptydatatemplate when there should be data..
Here is my current ListView
[Code]....
I have tried binding data OnPreRender and setting the page properties under the OnPagePropertyChanging events.. still only getting my empty template whenever i navigate through the pages when there should be plenty of data..
I often have some controls (like TextBoxes) for input parameters at the top of a page followed by a ListView to show the results.
When submit is hit, the LIstView shows the results using ControlParameters in the SqlDataSource.
My problem is when you first navigate to the page, the EmptyDataTemplate is shown. This can confuse users.
What is the Best Practice for not showing the ListView or EmptyDatatemplate until there has been a Submit button press?
Here I've a listview control whose datasourceid is set to one sqldatasource, listview contains a panel in a itemtemplate region. In the panel there are some lables which are bounded to the column present in sqldatasource. But In one label I have to assign some other value dynamically. can any body tell me how to access that label and assign value to it. Here's the code
<asp:ListView DataSourceID="sqldtsrcsrchre" ID="srchrelst" runat="server">
<LayoutTemplate>
<ul class="productlist">
<asp:PlaceHolder ID="itemPlaceholder" runat="server">
</asp:PlaceHolder>
</ul>

View 6 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 have a set of controls that enable the user to search one of two fields in a given SQL Server table. The ddlSearch dropdownlist specifies the field to search. The txtSearch textbox contains the search string. I have the following code working fine, except search string isn't being passed to my listview:

I tried adding a DataBind after End Using, but the listview still won't provide the search results. Note that I also have an EntityDataSource on page.
Am I adding this to the wrong event? Should this code be added to PageLoad instead of click event of Submit button? What other issues should I address? Is it possible for ListView to handle the search by itself? That is, do I even need other dropdownlist and textbox controls, or is there functionality builit into the listview control to search? Finally, can I enable a checkbox for each returned item? I will need this so that the user can select items to add to their order.

I'm working on a job seeking website where the job seeker can search for a job , the search box is located in the master page, that's why i passed the keywords as a query string, and then the matching jobs will be displayed in a listview.
the keywords will be taken from two controls: a drop down list which the user can choose the location of the job, and a text box where he can type a keyword.
the select command of the sqlDataSource of the data list is as the following:

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?

The situation: a FormView with an EditItemTemplate and an Insert Item Template. When the page is entered and a record exists in the datasource, everything is fine with the Formview in Edit mode and the Edit ItemTemplate being used. But when no record is present, the FormView uses the EmptyDataTemplate even though it was switched it to Insert mode. Here is the code used to switch modes, fired in the OnDataBound event:
protected void SetModeAndHeadings(object sender, EventArgs e)
{
if (FormView1.DataItemCount == 0)
{
FormView1.ChangeMode(FormViewMode.Insert);
}
else
{
FormView1.ChangeMode(FormViewMode.Edit);
}
etc...
}
Is the problem that it switched to Insert mode too late? What has to be done differently here to automatically switch between Edit and Insert modes?
i want to disable some buttons in my emptydata template. i tried using this code but it cant find the control. thus returning an error Specified argument was out of the range of valid values.

btnsaveini.Enabled = false;
There is user selected search criteria used to display both a FormView (Invoice header information such as ship_id, vendor, date, store, etc...) and cooresponding GridviewDetails (product details such as upc, description, unit cost, qty ordered, qty received, etc...) There is a one to many relationship between 1 invoice (formview) and many product details (gridview). I need to add the ability to insert product details to a particular invoice (ship_id is the link between the 2 tables) if an invoice currently doesn't have any. I have the emptydatatemplate programmed with dropdownlists and textboxes to capture the user entered information along with a submit button. However the insert doesn't occur.
I know the problem is how I am (incorrectly) using the findcontrol, but for the life of me I can't seem to find the correct syntax (been searching the forums for nearly a weeks implementing different syntax and testing to no avail!)
I have successfully implemented the ability to insert a new row using the footertemplate and was banking on some of that code to assist me with the insert of new details in the emptydatetemplate. Grrrrr....still not working. Below is the current version of the test page programming.
