Forms Data Controls :: Editing Populated Textbox From A Dataview?
Sep 28, 2010
I have a dataview running a stored procedure that's populating a textbox. I then want to edit (or not) that text and insert it using another query. However, whenever I populate the text box, it will always insert the original text. If i don't populate it, it will insert whatever text I input.
I am tryingto update my data on a gridview.... i have two ddl's and two textbox...when i click on the one ddl it post the value of the selectedvalue into the textbox and this happens the same for the other one..... I am using the rowupdating event handler... and here is what i have so far...
[URL] .... I Need to search record from GridView by using the textbox but not want to configure this with SQLDataSource Manually (Front End) therefore how to filter gridview from Codebehind.
HOW TO specify which columns are in a DataView from a DataTable. I want to create a DataView, that only has the columns from a DataTable that I choose, and in the order I want.
Example: // DataTable_MyTable ~~ Column #0 is for ID. I do not want my view to get this column. // DataTable_MyTable ~~ Column #1 is for TYPE. I want this column to come in 2nd place in my view. // DataTable_MyTable ~~ Column #2 is for NAME. I want this column to com in 1st place in my view.
DataView DataView_MyView = new DataView(DataTable_MyTable ~~ some how only get the columns I want, and in the order I want ~~);
// DataView_MyView now has only 2 columns. // DataView_MyView ~~ Column #0 is NAME. // DataView_MyView ~~ Column #1 is TYPE.
I have a datatable which contains the summery row as well. I just assign the datasource property of a gridview and call databind method to fill and display the records.
Now, when I applied sorting through dataview to the gridview, the sorting happens along with the summery row, which is a normal behavior. As a result the "Total" - column took place inside the data some times. I want to prevent this.
The best way out for that can be done by creating the summery row at grid view row databound. But unfortunately I could not change the datatable as per this requirement.
Can the dataview sorting exclude the last row of the datatable through any process?..
I know how to do this in a datatable but I would just like to learn how to do it in a dataview.
I have a dataview which is used to populate a gridview. It has the following column
userid Location 123 New York 124 Chicago 125 London
Now, I would like to know how to determine the 124 row and highlight it to a blue in a dataview used to populate a gridview. kindly note, i can do this in a datatable but not a dataview. I would like to learn how to do it in a dataview.
I have tried the online converters, and none of them that I have tried will accurately convert this. It still tries to add a .Item property to the dataview and that does not exist in c#. I know this is simple...
I'm trying to export a filtered dataview to excel. The code to export works just fine but it exports all the records, not just the ones I filtered on. For example, I have three dropdowns and the dataview seems to work just fine filtering on the dropdown parameters because it shows up correctly in my datagrid on my screen.
Im trying to populate my formview from a dataview in the codebehind and the order in which things are happening is causing it to fail.my formview itemtemplate is setup with some eval("fields") which is initially not populated (nothing bound to it) and the page loads ok. i think click on my graph which generates a query and populates a dataview.i then assign that dataview to the formview and run the bind.what happens when i actually run the app is that it says no data is bound to it.i set the debugged to stop at the point where my DV is assigned to my FV and the FV shows a data item count of 1 (as expected) if i keep stepping it puts me in to the eval statements on the aspx page says the data isnt bound. the error i get is
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
I am using a dataview to read a certain record from a database and then adding these values to different elements on a form (label, textbox) ..
One of the fields is a date/time and i only want to display the date without the time..
code:
{on page load} Dim dv As System.Data.DataView = CType(DEDS.Select(DataSourceSelectArguments.Empty), System.Data.DataView) lbl_startdate.Text = dv.Table.Rows(0).Item("'<%# Eval("evt_startdate","{0:d}")%>'").ToString() ' DEDS is my SqlDatasource .. 'evt_startdate is the date field coming from the DEDS datasource
.. It's not working .. I'm not sure how i should alter the date format ..
I have developed my application using Visual Web Developer 2008 express with Visual Basic code.
If I am working with 2 textboxs on a form, and I set the "Autopostback" to "true" for the first texbox then on the "changed" event, I can just add code to set the visibility to "true or "false" for the second textbox - it works fine. However, I do not seem to be able to figure out how to do the same thing when I am using a Dataview.
I have a table called "Customer" that contains 4 fields "CustomerName", "BasePrice", "LevelOfActivity", and "Discount".
My user enters information into this table using a Dataview form that displays the 4 fields.
When the user enters the value "L" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "false" - (I want to hide the field as this customer should not get a discount). If the user enters the value "H" in the field "LevelOfActivity", I would like to then set the visibility of the field "Discount" to "true" - (I want to show the field so the user can enter the "Discount").
I've got a Gridview bound to an objectdatasource. Sorting is enabled in gridview, but objectdatasource isn't doing any sorting. I can pick up the unsorted datatable from the Selected event of the objectdatasource, but I really want the sorted version. Is there any event on the gridview where I can access the sorted dataview it must be using internally?
Why am I asking? We're using paging as well (i.e. truncated data in gridview) and I want to loop through the full sorted dataview to find the primary key value to set selectedindex.
in my asp.net_vb web there is a text box (textbox1) in which a date is dispalyed from database (eg 21-Mar-2012) in another text box (textbox2) i want to display
if the date is less than 30 Jun then the textbox2 should display 1 Jul+the year of textbox1
if the textbox1 date is greater than 30 Jun the text box2 should display 1 Dec + the year of textbox1
i'm creating a webpage that contains a text box, whenever i type something in the textbox, i used to show some suggestions like google suggest.
I'm using a div tag to show suggestions and each suggestions is a div tag, so on clicking any of the suggestion, it will be loaded into the textbox, but i can't able to edit the suggestions easily, whenever i want to modify the selected suggestion in textbox, clicking the mouse pointer at some place of the suggestion and pressing backspace removes a single character from the suggestion and return to the end of the suggestion.
what is my ip
when i want to remove "my" in it, it will remove "y" from "my" and return the cursor to end of suggestion (i.e.,) after ip,
whenever there is a keyup event occurs on the textbox, then i use show suggestions that is similar to the entered character.
