Forms Data Controls :: Capturing SelectedIndex Values From Datagrid To Populate A Datasource?

Jan 18, 2011

I'm trying to populate a datasource for a dropdownlist (which is actually in an insertitem template field within a detailsview on the same page) with a selectedvalue from a gridview. When I select a row in my Gridview 1, I get the "no value for a required parameter" message. ( and I have tried various alternatives... setting the selectedvalue of the grid to a variable... setting the selected value of the grid to a textbox nothing seems to work. It seems like this should be a pretty simple thing. I think I'm missing something obvious! Here is my code:

Field in Details view to be populated by the datasource:

Forms Data Controls :: Formview Update Mode Not Capturing Control Values?

Jul 22, 2010

I've been spending two days on this. My page formview is in a tab container and I need it to update, insert and display data. Insert and display are ok as long as the default mode is Insert. The problem here is edit mode, it's able to get values from the db(oracle) and display them in edit mode, but when I click save, any values I typed out on the textboxes do not get captured. When I call on my db update class, it just sends old db values. Here is the process: formview shows data selected from gridview, then an update button is clicked to edit the data. there is also a SAVE button to send updated data to db. Example: description textbox = "test", then I type out a different value, and in debug mode, the textbox.text still shows "test" after clicking save.

Forms Data Controls :: Trying To Populate A Datagrid Using A Stored Procedure

Jun 7, 2010

I'm tring to populate a datagrid using a stored procedure that returns about 20 fields (this part I figured out), but the kicker here is that for this one particular page I only want to display about 6 of those 20 returned fields.

I did find on passing the procedure the parameters that are required, and populating the datagrid, but haven't found anything (not that I can tell) that explains how to only view certain fields that have been returned.

I'm using VS 2008 and VB for my coding against a MS SQL 2008 server. All of the stored procedures are working with current windows applications.

Forms Data Controls :: Populate A Datagrid On Selection From A Drop Down List?

Mar 17, 2011

This is my first post as a newbie to asp.net.

I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.

What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.

So far my edit page has a datagrid with the following code:

Forms Data Controls :: Populate Gridview From Numerous Control Values?

Jul 4, 2010

I have a number of controls on a form i.e date pickers text boxes and dropdownlists. Firstly i need to set up some validation rules on the search button click event so if one control is populated then another needs to be and others shouldn't be etc etc

Then based on the values i need to return a dataset to the gridview showing all the records where the criteria meets all the values. I just wondered the best way to do this... i.e should i use validators to test for the rules(they may be too complex though). Should I just create a string and pass it as filter to the full dataset or use a stored proc and pass the string as the where criteria? This would mean a dyanmic proc so I'm not sure if there are any benefits as it won't cache on the server .

Forms Data Controls :: Dynamically Binding Dataset Table Values To Datagrid's Header Column?

Jun 29, 2010

I want to dynamically bind dataset values into datagrid's header datafield.

Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.

i.e like ds.Tables[0].Rows[0][0].

Is it possible to do it in Datagrid ItemDataBound function like,

e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]

or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.

Feb 25, 2011

Forms Data Controls :: Updating The Datasource / Mark All The Values In The Binding Column Of Datasource If Checkbox In Headertemplate Is Checked?

Sep 29, 2010

Scenario:
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.

Web Forms :: Capturing Data From Dynamic Controls On Button Click

Dec 29, 2010

I've created a number of identical controls in a varying number depending on how many employees are under a supervisor. What I am trying to do now is to see which set of controls are checked via a checkbox and return a value from the label field in that particular set. Here is my code:

[Code]....

What I am trying to grab in particualr is the PayRoll Label. I've named sequentially as "lblPayRoll" + the counter. Which from what I think I should be able to do is get the total count of my array and from then loop through the controls and grab the label data.

Problem is that I can get the data, but it disappears after I click the button to grab it. I think I am saving everything to the viewstate, but they just disappear.
