I have a listview to display items from database and I need to automatically select the first item when the page first loaded, how can I do it?My listview is in one of the steps of a wizard control, and this wizard control is inside a popcontrol extender with updatepanel.
I have a "report" the users can run it basically creates a simple gridview. In the gridview the user can click on a claim ID. The claim id is then passed via url querystring to a claim management page. The claim management page uses a listview to display the various claims and allow users to edit them. I want to use the claim id passed in the url to locate the listview row to open in edit mode, so the user can make changes / alterations to the claim.
I have a C# VS2008 web app that uses a gridview control to display data, and have found a bug in the command postback processing, as follows:
This problem occurs when there is more than one page of data in the grid, and the user navigates to the last page. If the last item on the last page is clicked, the associated command event code for the grid is not fired. A postback occurs and the "__EVENTTARGET" parameter for the item seems to be corrent, but the page eats the postback, and therefore the last item in the list cannot be accessed. Instead, the web app will return a gridview display of the top n-1 items from the last page with no pager control at the bottom of the grid.
This problem does NOT occur if there is only one page of data - only if paging is being done.
I have records in a Gridview, when I click on the NAME of each item I want to open up and new page and display a more detailed view of the record, i.e. the extra details from the table. I have the following code setup:
I have a 3 text boxes. When i enter datas in and click the button it displays the gridview with filtered data. Now my problem is if there is no data in gridview it has to show "no data" so I used emptydatatext property.. The problem is, in the page load itself it shows "no data"
i m working on application that works similar to our email i.e when user enter his emailid and password his inbox should be display and those unread should be in bold and i have a treeview forinbox,sent,deleted .when inbox is selected the inbox detail should be displayed using gridview by default like in email the inbox data shoul be display on pageload so i have written databind code for grid view in page load event
I have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.
The InsertItem Template is in the first position, making it easy to insert a new record.
And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.
I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:
Page.Validate() If Not Page.IsValid Then e.Cancel = True End If
which works fine also.
The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:
Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating Page.Validate() If Not Page.IsValid Then e.Cancel = True End If End Sub
This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.
Here is the code for a typical entry of the InsertItem Template:
All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"
How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?
I have a gridview in which I have the autopaging option set to true, when i load the grid everything works on the first page, i can even go to second page , but when i click the edit button nothing happens and after that any click blows up the page giving me error Faile to load view state.
I have come from MS Access and am working through a couple of textbooks on ASP.NET 4. I am using the Gridview control connected to an SQL data source control.
As an exercise I am converting my simpliest MS Access page which is simple a form to request a new stock item in our engineering stores. I have a normalised table called [stock_requests] and part of this is a field calle [failure_mode]. This field is an integer and there is another table listing the possible values for this field.
This other table is called [failure_modes] and has two field:
[id] < the primary key
[mode] < the text to be displayed
In my main table [stock_requests] in the field [failure_mode] I store the [id] from the [failure_modes] table for the applicable record in the [failure_modes] table. So for example if someone wanted to select "Catastrophic" as the failure mode the [stock_requests].[failure_mode] field would be 1; if the user selected "Gradual" as the failure mode the [stock_requests].[failure_mode] field would be 2 etc.
Now, the gridview wants to display "1" or "2" but I want to display "gradual" or "catastrophic" without using views and all the headaches that brings. I have managed to sort out editting by using a templated field where I have a drop down list in this cell and I databind to a second SQL data source (imaginatively called SqlDataSource2).
what is the best method for displaying the text 'Catastophic' or 'Gradual' etc. when in normal mode (view mode)? Is it another templated field and what is the basic approach I should use? I reckon I should be able to work it out once someone points me in the right direction.
I have an issue that I've spent quite a bit of time trying to solve. I have a Detailsview and a Gridview that I have linked using the ID field, It has now been decided that they want to have individual pages for each Unit. I have this working for the most part, however the detailsview is not being displayed until I hit select the row in the gridview.
How do I get this to automatically display on page load?
ASP.Net Nested GridViews – GridView inside GridView with Expand and Collapse feature this artical works for me but i want to expand first row when page is loaded all the other record show as same as it is collapse. may be it is happen in this nested gridview
I have gridview control. visit [URL] but when i change page index of this i get error the following error
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
