The insertion part of the form works great. But my problem is in the form load part......If i leave a field blank(Null),then perform Save operation,close the form after successful insertion and then reopen the form,then it retains the previous values during the form load......This is only in case where i leave a field blank in the previous data entry in the database.......But if i enter values in all fields then form load is working great.
I have textboxes which is placed inside accordian (ajax control).In pageload event i have written the code to load values in textboxes. But onload event one error is coming as object not set to instance of a object. Values are not coming in textboxes.
Then i tried to initialize controls in textboxes .Then the error cleared. But
Values are not coming in textboxes. What may be the reason for this?
i have a string = "/a/value1/x/valueforx/b/value2/c/value3"
the keys a, b, and c can be in any order in the string that is coming in and will always be separated by a slash.
What i need to do is to find a, b, c and then add their values to a collection

I have multiple controls on my form. Text boxes, radio buttons, check boxes, etc. Is there a way to move through every control on the form and save it's value, status ? Like whether the radio button is checked, or not. The value of the text box, and save them all to a text file. Then, reload the values saved in the text file in the same sequence. Without doing all this one line at a time.
View 2 RepliesI have a few combo boxes that need to be loaded up once and displayed multiple times (whenever the main form is opened) The reason for this is because it's taking about 10 seconds for the form to load each time it's opened due to unnecessary re-querying.
Here is an example of what I have as a combo box source and what I've done.
I've put the query, connection, etc... in a module and call it on the login form - i don't get any errors but the data does not load into the combos.
'In Module
sql = "SELECT DIR_ID, DIR_NM FROM LTC_FBS_DIR ORDER BY DIR_NM ASC"
RConStr = String.Format(RConStrFormat, LoginForm.txtUser.Text,

Normally I've been lucky to find someone who has had the same problem and applied their solution but after hours of searching I'm not able to find a solution to this one. I've got a FormView which is default mode set to Insert. When the page is loading I'm checking to see if the session variable which the formview datasource is set to has a value. If it doesn't I've coded in the onLoad that some of the controls in the InsertTemplate would be set to specified value.

I've been literally googling for an hour now trying to find how to save variable settings to a file.I'm writing an application and I'm using alot of changeable variables. I want to be able to save these to a file so they can be loaded at application startup. I don't feel like using the regestry since I hate to write unimportant things to the registry.I remembered that I found a good example with simple code of how to do this with xml, but I can't seem to find the example now.
View 10 RepliesI would like to load a combobox with some values from an access database. On form load I load my information into a data grid view but if the user wants to add more information or edit what is selected in the DGV I will enable some text boxes and a combobox to show the selected data. I have not issue loading from the DB into the text boxes but the combo box has me a bit stumped. I have 3 columns in the database, periodno, start date and end date. I want to display the start and end date concatenated together. When the user selects a period and hits the button I want the dates to set a variable with the periodno that matches those dates.

View 9 RepliesWay to load regedit values/keys to a listbox or listview
View 10 RepliesI am looking for a way to save and load the values of all my controls present in my form.My form has around 100 controls spread over 7 tabs. The controls include (Multiline) TextBoxes (Strings), NumericUpDowns (Integers, Decimals) and Checkboxes (Booleans). If the user clicks the save button a "Save File" dialog should appear allowing the user to specify the directory and the filename of the save file.All the values of the controls should then be written to that file.If the user clicks the load button an "Open File" should appear where the user can pick a previously saved save file. All the controls should then adopt the values found in the save file.I have implemented Application Settings in my form, and now when I click save, it saves the control values through My.Settings.Save(). If I click load it loads them.However, my project requires that multiple save files can be made to reflect multiple configurations. As I understand Application Settings only allow for a single .config file in the Application Data folder.So how can I code a save/load routine to save/load different configurations?
