If I am passed a datatable and I cant change the column structure..is there anyway to set an existing column to a Primary key so I can easily Find() the row I am looking for?
How to fetch data in gridview and add newly added item column in same column? As I know fetch data in gridview, my prob is add new data in new column in gridview.
I have following issue: I have a datatable with a column which I would like to encrypt. This table has about 10.000 rows, and this particular column is storing 14 digit keys. Is there any way to encrypt all those keys in this particular column (just to make them useless if someone steals by db)?
I have a dataset that has around 5 rows. I also have another Datarow() array that has an additional 3 rows which I would want to add to the dataset. The structure of both the Dataset Rows and the Datarow arrays are the same.
Do I have to perform a loop on the datatrow arrays and add them one by one? or is there a better way of adding them in one go ?
I have one problem with my shopping cart that I really can't figure out all by myself.I want, if a item already exist in the datatable, the quantity to be updated for that item with the new number instead of creating the same item again.I have done a foreach loop because I think that is where I should start.Notes: MyRow[3] is the column holding the quantity.Code:
Below is a beginning attempt to increment through a DataTable populated by a Stored Procedure and create a new DataTable where every Category is represented by exactly four products. I need to add dummy product entries for some and skip over those with over four products.
A) - I think I understand the basics but this builing from scratch is not my practice. 1) I do not know how to query a previous row in reference DataTable. 2) I do not know how to jump to next row from IF construct. 3) I hope I am able to build a DataTable row by row. 4) Partial sample data is at bottom of pseudo code
if (dt.Rows[i]["Code"] == code) { Label lblLang = (Label)(((e.Item as GridItem).FindControl("lblLang") as Label)); lblLang.Visible = true; } else { } }
I am adding a new language Fr-FR in the code above. fr-FR already exists in my DB's Language Table. I do not want to add duplicate values in my table. There should be only one fr-FR.
I need to add rows to an existing (maybe) datatable in a dataset that combines the IIS6 index search with my own sql table. I keep getting object reference errors.
i have the dataset with one table.Table contains three column like 'Name','Location','Pin'.I would like to move the data from another table based on schema.
im trying to copying specific record from one datatable to another datatable i used below code
public System.Data.DataTable selectspecificdatarow(System.Data.DataTable dtg, int count, int startindex) { System.Data.DataTable dtn = dtg.Clone(); for (int i =startindex; i < count; i++)
[Code]....
its taking too long time in cloneing is there any better way to do this task which is Time effecent
I use a Detailsview, Entity Data Source to edit/update my table with only 3 columns.(it has primary keys).
Everything works fine inserts/edit in dev environment. but when i run this in release mode. i cannot update existing data in the database with the detailsview. whenever i update and save page gets refreshed, but nothing gets updated. but whenever i insert a new record, and then i try editing it. it works.?
Note: i handle DetailsviewItemUpdating,DetailsviewItemInserting events to do some custom checks.
I have a gridview that contains template fields with textboxes that is used to look up inventory items. The page loads using an arraylist to display a gridview control with a predetermined number of rows. There is also drop down control that allows the user to add additional rows to the gridview if needed.
Currently when a user has already entered some data if you use the drop down to add more empty rows all the original entrys are removed. I want to save the original data and then add empty rows at the end.

I have a word template in which I define lots of bookmark (textbox for user input).I have a grid view that I need to export to word.

I have two datatables, I want to get all records which are in one datatable but all matching records which exist in another datatable should not be available.
In terms of set, you can say that record which are in 1st datatable but not in 2nd DataTable.
I got this code which bind a datatable to a grid view. After the binding, i wanted to add additional column to the right of the grid, how can I do that? My codes below failed to do it.

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.
now when i type something in header Search cell , it shows the data of first page index only , it won't show me data from 2nd page index .. here's my code :
protected void PhasesTempGrid_OnDataBound(object sender, EventArgs e){ GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal); for (int i = 0; i < PhasesTempGrid.Columns.Count - 1; i++) { TableHeaderCell cell = new TableHeaderCell(); TextBox txtSearch = new TextBox();
[Code] .....
My gridview is in update panel therefore i did this in .js script :
