Forms Data Controls :: Updating The Datasource / Mark All The Values In The Binding Column Of Datasource If Checkbox In Headertemplate Is Checked?
Sep 29, 2010Scenario:
I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is:
I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.

DataSource Controls :: Sqldatasource Insert Method - Copy Data To The Other Datasource By Selecting Checkbox
Feb 25, 2010i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?

DataSource Controls :: Inserting Data With Object Datasource?
Aug 9, 2010This is the first time I have been working on databases and I am trying to insert data using an object datasource but no data is being inserted and no exception is thrown.

Feb 25, 2011I am familiar with populating a gridview with data. I am able to bind the Data pulled from the database into the gridview

View 4 RepliesForms Data Controls :: Getting The Value Of Checkbox From Datasource?
Mar 17, 2010Presently I am binding the grid using the SqlDataSoruce by a stored procedure.
The output of the stored procedure contains more columns as compared to the columns in the datagrid.
In the grid there are some checkboxes also.While saving the checkboxes in the database I differeniat them in different columns as checked and unchecked.
Now while retrieving I need to check if the record that is being returned is coming from a checked column or unchecked column.
Once I have that I need to check or uncheck the checkbox on the datagrid.
Now My problem is I am not able to get the checked or uncheked column value from the sqldatasource.
How can I get that?The below code is for binding the grid with the datasource.

Jan 19, 2011I have an application that needs to read data from a view and do some extensive manipulation prior to delivering it to a chart control (without modifying the original data in the database).

Forms Data Controls :: GridView And Swap The Datasource
Feb 10, 2010I have a GridView and can swap the datasource just fine with code. However, The GridView also has a TemplateField with a dropdown connected to a different datasource. How can I swap that one with code too? I don't see how to drill down to find it. I've found stuff on line about accessing the TemplateFields with code, but it seemed to complex for the simple task I am trying to do.
View 3 RepliesForms Data Controls :: Gridview And Excel As Datasource?
Mar 26, 2010im using an excel file as a datasource for my gridview...i can pull all the data into the gridview fine. i am now hoping to allow the user to update the data in the excel file through the gridview. is it possible to update the excel file in this format i.e. allow the user the read/update the excel file as if its a database. i see some references in google that its not possible to update the excel file as the writeout causes problems. does anyone have this working...or should i look into trying to use another datasource.
i was hoping to use an excel file as the app is on a shared server and it would be handy just to have the excel file in the app folder as there is not much data involved.

View 9 RepliesForms Data Controls :: Delete Row From ListView With No DataSource?
Apr 28, 2010First time using a ListView control, I have it inside an UpdatePanel:
[Code]....
[Code]....
[Code]....
[Code]....
When the UpdatePanel Loads, it feeds the data to the ListView. Whenever the user clicks on a row in the ListView, a new window displaying a "note" pops up, the ItemDataBound event ties it all together. What I'm trying to do is add a button to each row so that the user can delete the row. This would call a Sql statement and then the row should disappear. I followed a couple of articles I found on ListView on how to do this, so I added a button called imgBtnDeleteNote (see markup above) and set the CommandName = "Delete", hoping that it would trigger the ItemCommand and ItemDeleting event (I have some bogus code in them, first I wanted to see if they would trigger).
The problem is that they don't seem to get triggered when I click on the delete button. All the rows in the listview disappear, and when I manually refresh the page they come back. My guess is that the events are not firing because I'm not using a DataSource object in the aspx code, but I'm not sure.
Forms Data Controls :: Reload Datasource And Dropdownlist?
Jun 10, 2010i think i can't see the forrest for the trees.......there HAS to be a simple way to do this. so i created a web page and on that page i have two dropdown lists. the first is STATE and the second is COUNTY. the STATE is a static list. but the COUNTY is generated whenever the STATE changes. now....when i set up the COUNTY dropdown list, it prompted me for a datasource. i have a store procedure which takes the 2-letter STATE code and returns all the counties for that state. so i set up the datasource for the COUNTY drop down list by just following the prompts from visual studio. i gave it a default state of Alabama (AL). and all is fine. so here's my question: how can i reload the datasource and subsequently the COUNTY dropdown list? i see no way to access the datasource that the environment generated for me.
well.....i thought.......i'll just do it the old fashioned way and set up a command.......connectionstring.......and sql statement and load the results into a datareader (do i REALLY have to do all that?)
but it still doesn't work. what's the simplest way for me to just re-fire my stored procedure and pass it the STATE parameter and reload the datasource and dropdown list?
