However the onclick does not fire the ListView.Command or ListView.SelectedIndexChanging event? If I add a button with CommandName="Select" it works as expected? The POST data is the same!
when i click on the textbox which is inside the item template of gridview then onclick event should fire and then call the javascript function but my problem is that there no onclick event option in item template's textbox
I've implemented a ListView to display selected data from a DataTable. My listview is one row high and 4 columns wide. I've setup a DataPager to the left of it and another to the right to allow the user to access any item in the ListView.My problem is simple: When the user adds a new item to the DataTable, I rebind the data again { e.g. listView1.DataBind() }, and then I proceed to select that newly added item. BUT no matter what I try, nothing works! More precisely, I do this: listView1.SelectedIndex = #; where "#" is the appropriate index number.
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 simply am trying to add a color to the select item background within the select elm after a user makes a selection from the select elm. The result right now is that in firefox, the colors will change, but only during selection ... after the selection has been made the background for the individual selection is still white.
This code works fine in IE but so far my efforts have been thuarted in FireFox.
[code]....
P.s I made an equivalent javascript method and made some attempts at it, but the result is still the same. The background color of the item is changed ... but only is visible when making a selection, NOT after the selection is made.
// Select item in first DropDownList myCascadingDropDown_1.SelectedValue = itemValue_1+":::"+itemText_1; // Select item in second DropDownList myCascadingDropDown_2.SelectedValue = itemValue_2+":::"+itemText_2;
How can I do this in JavaScript?
EDIT:
I can select my desired item in the first dropdownlist. The problem is however, that new values based on that selected item (it is a CascadingDropDown, remember?) don't show in the second dropdown so I can't select anything there. I would need to somehow invoke the update method of the second dropdown manually.
i have a listview. The listview contains a usercontrol with ID="ucEquationBuilder1" which is added only! in the SelectedItemTemplate.I've came along some post which stated you can't find the control in the SelectedItemTemplate unless it is also in the the ItemTemplate.
To me this sounded ridiculous. Untill i ran some tests, and indeed i was able to find all other controls (TextBox's Labels) which where both inside the itemtemplate and the selecteditem template.
To me this is quite frustrating. Is there a way to retrieve the control which is only inside the SelectedItemTemplate without adding it to the itemtemplate?
I have this control on a page. The selections are static. The "maximumlevels" is set to 6. When I click on an item at the 4th level, I can see the postback occur but the "click" event doesn't fire! I'm totally baffeled. I've tested this in the Page Load event. At this point the PRIOR menu selected value shows. On the next menu_click, the previous selection shows. The first menu item is "selected" and has a value of "Overview". The fourth level item has a value of "Child". No matter how many times I selected that item, my check in the Page Load shows the value to be "Overview". I've tested the 3rd level items and on click, I can see the prior menu item value. When I click a 4th level item, the value never changes from the last 3rd level or higher item selected.
How can I use required field validators in the insert item template in a listview control? The empty fields in the insert item template are preventing the user from deleting or updating ay other row.
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:
[code]....
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 project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.

I am trying to get a drop down and a form view to work together. I've never used form views before. I also am using the entity framework to do everything. This is also my first time with it.
I want to be able to have a drop down, that is populate from the same data source as the form view. So far that works fine.
I then want to be able to change the drop down item, and it change the form view item that is displayed. I cannot figure out how to make this work.
how to do this when the checkbox in listview layout template check select all checkboxes in listview itemtemplate.I dont give 'Eval 'field to checkbox present in itemtemplate.
My situation is a little strange I guess, suggestion of engineering is acceptable.I have a DropDownList, on my "user" creation, called "city". When I'm creating the user I can create other city, but for this I have a button which redirect to other page.So, ok. I've created the new City and now I click on my DropDownList of cities and guess what?! The field is not reloaded.My first idea is every that I click on DropDownList, reload the data, but I can't find some OnClick action for Asp.Net DropDownList.
One of my webpages has an asp.net ListView control, with an insertitem template defined. I would like to allow the users of the page to enter data in a text field in the insertitem template, press the enter key, and trigger the insert event (which normally happens when you click the 'insert' button). I've tried simulating the button click event in javascript, but that doesn't seem to be working.
