I noticed that with some of the data controls (like gridview and listview) the page loses focus when you click edit, update, etc. So if your data control is somewhere lower on your page, you'd have to scroll down to get to it again. Is this normal or is there a way to keep the focus or location on where you were previously?
View 2 RepliesI have a GridView that has approximately 800 records. I have a search feature that finds a record and focuses to it. When I click Edit for that record, the Gridview flashes and goes back to the 1st row. If I search for the record again it is in edit mode. Is there some setting to keep focus where it is? I added the following code to try and keep focus, but it doesn't work.

I try to postback my page to the server using ctrl+Enter sequence.Without UpdatePanel it works well, but it works only two times inside updatepanel and then my control loses the focus. So I have some questions:
1. Why my control loses the focus if it is located inside updatepanel?
2. What is the best way to use ctrl+Enter sequence to post the page to the server?
Here is my code:

I have a webform that the user inputs a date via a javascript popup calander, then it auto populates a textbox with 45 days after the inputed date.
My question is is there a way to have a postback once the input date loses focus. Here is my page.

I have 4 buttons and 1 FormView.
The FormView has AllowPaging = true.
When you click on a button SQLDataSource1 is bind to the FormView.
So you always have 4 pages.
The data in the FormView has an ID.
When you click Button1 you know you want to see the data with ID=4.
When you click Button2 you know you want to see the data with ID=1.
When you click Button3 you know you want to see the data with ID=2.
When you click Button4 you know you want to see the data with ID=3.
What I want is: when you click on a Button you get the page in the FormView
that corresponds with the ID of the data.
So page 1 isn't ID=1!
What do I have to program to get this working?
Why I am unable to setfocus to my list box if the index > 820
My list box contains 2000 items and the index is not able to set the focus if the index > 820
I have a rather large datalist on which I have implemented an editing capability. When I click on my edit link, everything works as expected except that when I bind my data focus returns to to the top of the screen, so my user will have to scroll all the way back down to the item he wants to edit. Is there a way to keep the page centered on the item in question through the databind?
View 2 RepliesI have my data grid and sort on a column but the row formatting stops working. I simply selected a format using the autoformat option and picked classic. Am I meant to reapply the row formatting after the sort? And if so how?
View 1 RepliesThe new values entered by a user are lost when a error occurs.
I tried to solve this by catching the error in the item updated event as per the code below
[Code]....
however the data in the form gets set back to the original values.
It seams as though the object data source is rebinding the form. How can i determine if this is the case? Is there a way to stop the datasource from rebining?
I create a gridview dynamically to fit the contents of a datatable...This form will have other dataatbles thrown at it but for the moment I am only working on one to work out the details of the process.I will post all my code below...the problem is this. The code successfully geenrates the gridview the way I want however...whenever I select a row all the cells including the header cells dissapears

I have a Gridview with edit and update feature enabled. It displays the data correctly but when I click on the Edit linkbutton(to edit the data), I get the error "Object reference not set to an instance of an object".
I tried debugging and found that the row which I click (say editindex is 1) loses its value. I could identify this while debugging the code, when the code flow moves to the rowdatabound event, the label (or for that matter any control in the rowdatabound event) shows a null value and eventually errors out.
I am unable to figure out as to why the control specified in the rowdatabound event loses its value when editing. Note: The lost valueow data is the one which I tried editing.
I am attaching the code which I have written for the rowdatabound event.

In my access datasource, I have set the selectcommand to what the user desires via a DDL. So the user chooses say, all names beginning with "B". But as soon as user clicks to page to the next page, the filter is gone. What is the way to preserve the filter. I have only merely rebound the gridview in the Pageindexchanging event which obviously is not doing the trick. Does this call for a session var to hold the users choice?
View 8 RepliesI have a gridview with columns 'Edit', 'Delete', 'View Results' and other details. The 'Edit' column opens a modal popup to edit the record. The 'View Result' column is in a login view and this column is only visible to users belonging to the group 'Manager' as below:
[Code]....
When the page is first loaded, the hyperlinks are displayed correctly. however, after editing a record and saving the changes, the 'View Results' column loses the hyperlink.
I tried creating a temp hyperlink column outside a loginview control and this seems to work correctly.
I have a bound datagridview with the associated tableadapter, dataset and bindingsource. A different component in our application can add or delete rows displayed by the datagridview. When this happens, the underlying database edits are correct. The problem is that the datagridview seems to lose track of the data.
Currently, when we receive the event that our data has changed we do the following.
this.DataSet.Offers.Clear();
this.TableAdapter.Fill(this.DataSet.Offers);
this.BindingSource.ResetBindings(false);
this.DataGridView.Refresh();
If our example had something like 5 items displayed in the grid and a row was deleted, the grid refreshes with 3 items shown. If we manually refresh our grid through a button calling the exact same code, it displays the correct results. Is this an asynchronous call? Should we be refreshing the grid in a different area?
I am having a ASP.net application it having three pages ,page 1,page 2,page 3,when the user navigating between this pages I want to maintain the view state in page level after postbacks(i.e.) .If a user visits page 3, passing some query loads some data .then he moves to page 1 doing some entries .after that he once again moves to page 3 now I want to display the data previously available at the time he moves to page 1, same
way I want to do to my three pages up to the user logging out.
I have a custom radiobutton and it renders fine but loses state after postback.
How can it be modified?

Ive added checkbox to each gridview row like this:
[Code]....
I grab value of selected checkboxes like this:
[Code]....
So. It works fine, but when i change page of gridview, previous page loses selection and set all checkboxes to false.
Probably this is because paging causes postback, but still, is there an easy solution to rewrite my code, so it will work with paging?
Maybe theres a way to disable postback on page change?
I have the following simple code:

So when i select "Yes" from the first drop down, the "hiddenDetail" label becomes visible and when i select "No" from q1 the "hiddenDetail" label becomes invisible.The problem is that because i am using AutoPostBack when you select "No" the "hiddenDetail" loses its children (i.e. the label inside it) which is obvious why but i am wondering, is there anyway i can make the "hiddenDetail" invisible (sort of like display:none in style) in VB without losing its children. Or is my only option to work with this in
Currently I'm designing a web page which will be used for touch screen device. In my gridView it got one button ItemField column so when this button is clicked it will update another column value. So if I got more than 30 records and I want to update the last record I need to scroll down the page to the end and do update. Up to here everything is fine. But the problem is after I have successfully updated the last record; the page will refresh and back to the first record again. So when user wants to view record which they updated they got to scroll down and check. So I just want to know is there any way that allow me to set focus on the updated record. So each time user done update they can straight a way check the result and no need to scroll down.Cos this will be very troublesome for them.
I got think of using Paging, but the page number size is too small ,I don't think it is good to use on touch screen device.
I'm playing around with storing application settings in my database, but I think I may have created a situation where superfluous roundtrips are being made. Is there an easy way to view roundtrips made to an MS Access (I know, I know) backend?
I guess while I'm here, I should ask for advice on the best way to handle this project. I'm building an app that generates links based on file names (files are numbered ints, 0-5000). The files are stored on network shares, arranged by name, and the paths change frequently as files are bulk transfered to create space, etc.
Example:
Files 1000 - 2000 go to /path/1000s
Files 2001 - 3000 go to /path/2000s
Files 3001 - 4000 go to /path/3000s
etc
I'm sure by now you can see where I'm going with this. Ultimately, I'm trying to avoid making a roundtrip to get the paths for every single file as they are displayed in a gridview.
I'm open to the notion that I've gone about this all wrong and that my idea might be rubbish. I've toyed around with the notion of just creating a flat file, but if I do that, do I still run into the problem of having that file opened and closed for every file displayed in a gridview?
I have created a async search of a gridview, where the displayed data only shows items that match whatever is typed into the text box. After i type the search the grid refreshes the results, but the focus goes away from the textbox itself, which gets really annoying. is there any way to keep the focus on it?

how to focus on grid Row while editing , i mean preserve position after clicking editing or updating
i have gridview of 5000 rows i don t want to scroll up or down after editing or updating, i want to return to the same row to make sure that this row is updating
I have an windows application, in this i have one grid view and am filling the grid view rows dynamically.
Now I would like to focus the last row of the grid while filling in which it is focusing the first row in the grid.
I am trying to set the focus to a control in a gridview (QTY).
<asp:TemplateField HeaderText="Quantity Needed">
<ItemTemplate>
<asp:Label ID="id" Text='<%# Eval("id") %>' runat="server" Visible="false" />
<asp:TextBox Width="30px" MaxLength="4" ID="QTY" runat="server" AutoPostBack="true"
OnTextChanged="check_qty" />
</ItemTemplate>
</asp:TemplateField>
I need to set the focus on the QTY control in the next row in check_qty. I was able to set the focus on the control in the current row by using:
row.FindControl("QTY").Focus()
but I need to set it on QTY in the next row.
