Update Table, Where Column Name Is Selected Dynamically - DropDown.SelectedValue, C#, .NET?
Mar 10, 2010
I want to Update Column of a Table where ColumnName will be DropDown.SelectedValue.Example: A set of RECORDS will be displayed from a Customer Table where CUstNo ='1234' and City= 'Chicago' and Grade ='B' Once displayed I want to Update the grade to 'A' of all those customers from the above criteria. In My case I have like 100 Columns, so in where Clause Column Names will be selected from a DaropDown.In My Query, Update Customer SET ColumnName= 'some value' where ColumnName ='ActualValue'So how can I pass the ColumnName which is Dropdown Selected Value. I believe I can't give as Update Customer SET DropDown.SelectedValue = 'some value' where DropDown.SelectedValue ='ActualValue'
I have three dropdowns, which are all loaded in the same function. How do I grey out dropdown 2 & 3? I want them to activate if a certain choice is made on dropdown 1.
Dim Formview3 As FormView = CType(FormView1.FindControl("FormView3"), FormView) Dim dropdownlist1 As DropDownList = CType(Formview3.FindControl("DropDownList1"), DropDownList)
I have a gridview with a dropdown list that was created programmatcially. I want to have access to the selected value and to that row's Id. I have the dropdownlist created in *Gridview_RowDataBound* and I am able to use the text in the cell but my addHandler is never fired. Where do I give it the Add handler. I believe I can assign it the addhandler in RowCreated but how would I be able to set up the add handler if the button is created in rowdatabound?
[Code]...
It fits best in Rowdata bound because my dropdownlist items don't duplicate but I need to be able to use the addhandler I created.

I have a datagridview combobox column with data bind into it. I would like to set it selectedvalue to a value by default. How can I do it? because it does not have any selectedvalue option.
Attempting to run an SQL statement to UPDATE a column in a table with new data. The column being updated is defined as varchar(40) and the new data is 41 bytes (varchar(41)). I get a generic 'data will be truncated' error message, but no detail on which column caused the problem. I've attached a sample VB program to illustrate the issue. In this scenario, Company is defined as varchar(40).
My question: Can I get a more detailed error message? i.e. can I get an error message that tells me the row and column that the truncation occurs in? Often times, I may be updating hundreds or thousands of rows and only one value in one column from the source file is too large for a database cell. As a related question, does each OLEDB provider create its own error messages. i.e. will the MS SQL Server OLEDB provider potentially give different text in the error message than say the MS Jet OLEDB provider?

Below code is supposed to update a table in oracle with rows imported. But it seems to update all columns in the table with only the first column which is imported from the CSV file. I figure its the "ReadFields" property which needs to manipulated/changed.
I have a gridview loaded with data from my database and a gridview swapping function which after exchanging data between rows with a column call "Priority", I want to save these changes back to my database.

As the title says, when I attempt to update a row in a table in a database, I recieve an InvalidCastException. I am unsure why, since the variables I am using should be, and indeed, when I check them at runtime, are filled with the correct data.
I am trying to update using the method wherein the row that is being updated is identified with all the variables already stored. Interestingly, Intellisense is telling me that EntryID, the primary key, is only necessary in it's original form, and that the variables that I am attempting to update have question marks after their type.
I am looking for the best way to edit and update the value of a database column that is defined as data type TEXT. You can't use a replace command in SQL and if I read in the value, update the data and update the record, the changes are not applied.

Depending on whether the type of control is a dropdown, textbox, or check box (feined in the table) it hides or shows the relevant control type. If it is a dropdown it needs to get its values from a CSV in a corresponding column. I have a SP that returns a these in table form if passed the id of the relevant row.How do I get that is from the gridview to pass to the drop down and load it correctly?

How to set up a Chart using the new MS Chart control. I want to be able to populate the data via SQL because the user will be able to dynamically change the values via drop downs. The format of the data will be the same (Qty, Time Period) but the Focus of that data will change. I'm honestly not sure where to start, I can draw the chart but I have no idea how to populate it with data via code so it can be changed dynamically. VBE 2010, and I'm hitting an AccessDB

I am dynamically creating and adding dropdown controls to DevExpress XtraGrid.That works fine and I can add a dropdown control to any column I wish.My main problem is that I need to have the first element in the dropdown control displayed. But after I dynamically add 3 dropdown controls to the grid, only the last one has the element displayed. The previous two do not.Although, I add the elements
this is what the code looks like:
vb.net Dim column as DevExpress.XtraGrid.RepositoryItem.GridLookupEdit For i as Integer = 0 to dsSometing.Tables(0).Rows.Count - 1 column = New DevExpress.XtraGrid.RepositoryItem.GridLookUp
[code]....
The code will go tru and add lets say 3 dropdown controls, set their .DataSource to datasets I need, but it will only show .NullText of the last added control.
I have a dropdown list that will add new titles to my database, however I would like to add a textbox that will allow the user to type in a new title if there is nothing in the dropdown that makes any sense for what they are trying to add.
I have the dropdown dynamically getting titles from the database. Unfortunately, this means that the first value in the dropdown list is not a default that says "Select an option." I don't know how to get the dropdown to have the first option listed as "Select" when the values are being pulled from the database. I can't add Select an option to the database so how would this even work?
What can I add to my codebehind that will allow the textbox to insert into the database if the dropdown list is not inserting anything? Right now I don't have any codebehind for the textbox but I do have the dropdown list inserting the correct information.
I just tried to fill my dropdown in vb.net and I have the same result. The dropdown is full but when I do a postback I have no selected value Actually on the server side when I put a breakpoint on the dropdown, the item count is 0. I don't understand why... It's like the 8th dropdown list in this project and everything is the same but this one doesn't work.
I don't do any binding on the page load. it's all in the aspx file well it works ONLY when I add autopostback="true" SelectedIndexChanged="dd_ressource_composante_SelectedIndexChanged" for the dropdown.And theres no code in dd_ressource_composante_SelectedIndexChanged It's vb.net for the server side?
doing dropdown list selected index changed. I wan to select an item in dropdown list and display in textbox but I got more than 1 textboxes. Is the style sheet (.css) going to hard code by our own. how do I go about starting with it as I am a beginnner using visual studio.
I am having trouble using the values that were selected from the dropdown list. How would you reccommend passing the selected values from the view?Ideally, we want to use the selected dropdown values to determine a query.
