I am selecting time from dropdownlist. and want to convert it in datetime and store it in database. When I am converting it to Datetime using following statement.
DateTime start_Time = Convert.ToDateTime(start_ts);
but it is showing as : date:12:00:00AM
In my asp page when press a button, a gridview will be populated with data from db, but beside the columns from database i need a new dynamic column in gridview, to contain only dropdownlist with items number from 0-n.
This far i managed to do it, with some research on internet (i used an intemerdiet datatable to apply ItemTemplate from GridViewTemplate class, and than merged it to datatable containg the result from query, so the gridview's datasource si the merge of this 2 datatables).
The issue is that i don't now how can i access the values selected by user in the dinamically dropdownlists, 'cause i have to save them in DB.
Attach is my GridViewTemplate class code, and .cs and .aspx code.

View 1 RepliesIs it possible to add values from different database rows to a dropdownlist?
I'm currently trying to add both ItemSizeSmall and ItemSizeMedium, but through trial and error I can still only add one row from the database. I want the dropdownlist to display "Small" and "Medium" etc.
I guess my primary question is: How do I create a database with product size attributes?
I apologize if this thread should be in another forum, but if the dropdownlist can display two database rows I'll settle with that solution.
Could the database look like this:
table1: product
PK: productID
table2: productAttribute
PK: productID
PK: attributeValueID
table3: attributeValue
PK: attributeValueID
FK1: attributeNameID
table4: attribute
PK: attributeNameID
name
If this is right: How do I make the dropdownlist display the different sizes?
I have a Gridview on my aspx page. On my page_load event I check for a record in the database, if the record exists for that row in the gridview I would like to add a new column in the same gridview and add a button control to it. This adding of new column in the Gridview should happen in the codebehind (c#). see the code I wrote for this, but when I run it, it does not create any column on the gridview page.

How do I add maximum rows that can be added ?
I have 3 textboxes , 1 dropdown , 1 Button and 1 gridview .
Textboxes ID are :ACode , ADesc , ASeq
DropDown ID is :CPhase
Button ID is :AddRowBTN
GridView ID is :PhasesTempGrid
Now whats the story is ?After adding some data into textboxes , when a user clicks ADDRow BTN , that data gets saved into datatable , then that datatable gets binded to gridview and it shows my textboxes data in it .
What i want to achieve ?In my gridview i am use templateField and inside that template field there are textboxes ( Let the users edit the row without clicking any button ) .
Take an example of dummy data and problem persisting in there :for e.g i put some data in textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"Then i click Add BTN , it saves the data in datatable and show in gridview , now if i do this in gridview :ACode = "Edited ABCD"ADesc = "Edited EFGH too"ASeq = "WoW There"Then i click Add BTN , it removes the edited record in gridview and shows original data which had came earlier from textboxes :ACode = "ABCD"ADesc = "EFGH"ASeq = "HIJK"I don't want that to be done ... Simple is that user can enter data from textboxes , click the btn to submit into grid then he can edit the data like he want ... data must not get flashed , here's my coding i have done so far :
public void AddNewData()
{
var dt = new DataTable();
if (ViewState["myDatatable"] != null)
{
dt = (DataTable) ViewState["myDatatable"];
}

Im not binding the database to the gridview via design view I'm binding it programatically in the default.aspx.cs file
So far the only tutorials I've encountered are ones the have the database bound through design view and gridviews with only one column that can be added. In my particular example I have multiple columns that need to be added and I have already bound the data to the gridview.

So I have a gridview control and I am binding it's datasource dynamically base on a dropdownlist. The gridview contains autogenerated columns with auto generated edit buttons. The datasource binded to the gridview is IQueryable<T> where T will be different for different datasource.
My detail problem is below:
A GridView binded to datasource dynamically with all autogenerated columns. When user click edit link, it will display value in autogenerated textboxes.
When user click update link, I am able to capture the user entered value in the textboxes in RowUpdating event, then pass those values to Linq update function to update the database. Now, the problem begin when I try to dynamically add validation controls to each editing row. In RowDataBound event, I am checking the editrowindex then adding validation control to gridview cell and pointing to cell.controls[0] which is the textbox control when the row is in edit mode, I am dynamically setting the textbox control id so that the validation control can set controltovalidate property. The validation control works, but the updating function is setting everything on the grid to empty string.
I am check the textbox text value in the loop, which returns "" for all cells except the id column. It was returning the correct value before I add the validation control. I guess since I added the validation control on rowdatabound event, will it rerender it's own autogenerated textbox in edit mode so that the text value of textbox no longer available in rowupdating event?
Is there a better or correct way to get the cell textbox value? I am using ((TextBox)dc.Controls[0]).Text where dc is DataControlFieldCell in rowupdating event.
Is it possible to convert gridview textbox(when in edit mode) to combobox without using EditItemTemplate or place control in EditItemTemplate?
View 3 RepliesI have gridview created dynamical and added text box to the footer so I can insert into the gridview but I'm using findcontrol but it saying the value is null.
