Web Forms :: Finding The Right Textbox In Listview?
Jan 31, 2010
I built an application where I use the ListView control to display data from my database. The user will be able to see a product image, product name, a dropdown list that contains various sizes of the product, a textbox and a button. All these controls are shown for each product from my database. The user is going to be able to select the size from dd-list and enter how many pieces he wants, and click the button. I wonder if there is someone out there who knows how I can check if the user has typed in the correct textbox. I have been using the findcontrol to find the correct textbox. But it turns out that it is not working properly. I want to verify if the user typed in the corresponding textbox, where he has chosen the size of the dd-Llista.
Here is what a bit of my code looks like now:

I have a gridview with a template field column. In the edittemplate of that column i have a textbox. In the next column of the gridview i have a button. When i click the button i need to find the value of the before mentioned textbox. I do it like this:
gridview1.selectedrow.findcontrol("textbox1"). This sometimes work just fine and without a problem but sometimes it seems it can't find that control and throws a null reference object. The error it's random like i said, sometimes just work and other just don't work...

I have a listview control which is bound to DataTable object. When a user clicks "Add", I am creating a new row in the underlying datasource and refreshing the datatable so that it includes the new row and displaying the listview. My requirement is to "select" the newly added row after listview is refreshed. I have the ID of the newly created row and it is bound as one of the columns in the datatable.Now my question is, how can I get the index of that particular row which was newly created from the Listview so that I can set its SelectedIndex.

I know this not the right place to ask javascript related questions.
But I dont understand how else to get the answer.
I have built an application using asp.net 4.0 and entity framework. I have implemented the routing feature introduced with the .Net 4.0 version.
Now, I have a page which will fetch products from the database and display them in a listview. For the paging purpose I have used the DataPager.
I had a really hard time making the paging feature work with DataPager as it is not fully compatible with the Routing feature(asp.net 4.0).
Now I want to give the user the option to select multiple products to compare. For this purpose I have placed a checkbox with everyproduct.
Now the problem:
I dont know how to find which checkbox was selected. i want to find the checked checkbox using javascript.
I have binded the list of products to the listview at two occasions; once directlly to the listview in page load and second time during the pre_render event of the dataPager. (As I said I had a really hard time to get this combination to work; Listview+DataPager)

I have 2 textboxes that I am using for StartDate and EndDate in DateTime format, I am using DetailsView with Insert and Edit Templates, I was provided this code by "compguy2100", in order to make sure that the EndDate comes after the StartDate by at least 1 Minute. What I can't figure out is how to get the code to find the textboxes in question so it can validate them. I've used Detailsview.findcontrol with other controls however they are used with Item updating or inserting. I need this to run once the user has either entered a Date and Time and tabbed to a different dataentry cell. I've tried to use this code in the TextChanged event with no luck.
Dim StartDate As Date
Dim EndDate As Date
Dim Difference As TimeSpan
StartDate = CDate(txtStartDate.Text.ToString())
EndDate = CDate(txtEndDate.Text.ToString())
Difference = EndDate.Subtract(StartDate)
If Not Difference.Seconds >= 1 Then
lblDifference.Text = "Please make sure the end date is greater than the start date"
Return
End If

Is there a plugin that can group data and present it in a tiled format? I'd like to implement JQuery in place of the .NET Listviews that I am currently using. My current Listviews dynamically group three fields per div, with each div presented in two columns by three rows with paging.
I've looked at many plugins through numerous Google searches, and have yet to find one.

I have a listview that is retrieving some values from a database and showing them. The information are; product name, price, etc. At the end of each row, I have a textbox and a button. Within the textbox the user is able to insert how many items he wants of that particular item and by clicking the button I want the value from the textbox retrieved. It may be relevant to mention that
with the button is a event attached (OnClick) which is where I want the value of the textbox to be retrieved. The part that is giving me problem is retrieving the textbox value for that specific row when the button is clicked.

I have a ListView control that makes use of a DataPager. In each row of the ListView there is a text box where the user will enter some notes relevant to that particular record. Then they use the DataPager to navigate to the second page of records. If they then return back to the first page in the ListView the text they entered is gone.
Question: Is there a way (through use of a paging event or databound event maybe?) to retain the textbox values between paging events ?
I would like the user to be able navigate backward or forward and still see the text heshe has entered.

I have a listview that has n rows.
Within the EditItemTemplate and InsertItemTemplate I have a cell that has a textbox and a button.
When the button is clicked a popup window is shown, where the user can upload a picture. The name of the uploaded picture is retrieved.
Now I want to send that picture name back to the textbox within the listviews EditItemTemplate or/and InsertItemTemplate (that is ofcourse one at a time depending on what the user is doing, inserting or editing a row).
The code I have written so far looks like this. The below code has been abbreviated
[Code]....
The code behind looks like this (also abbreviated). Actually I don't think the code behind is needed, since its mainly javascript from the popup window (child page), but nevertheless here it goes.
[Code]....
And at last the child page / popup page.
Well there is not anything to see here, cause I'm using the Telerik RAD upload control, which is doing everything for me.
However the line below may be of interest. Here I'm taking the name of the uploaded file (picture) and printing it to a label.
