Edit Dataset Column Value In C#?
Feb 2, 2010
i have dataset having one table have 5 columns fill data from database.
When i run application datatable contains more than 50 rows, I would like to update value of datatable after getting data from databse. My requirements are This table have few cells having Null value, I would like to replace null with "-" ? One column is System.datetime datatype, where i would like to remove time. I would only like to have date?
Here i am thinking that i apply one loop of rows present in datatable and update cells accordingly. But i am searching any direct update method?

Can someone tell me if there is a technique to make an entire Column within an gridview (for example digits) editable (instaed of a single row) and update this column after changing values by press an Update-button?
A commercial solution is also o.k. with me, but, of course, a method to do it ourselve would be nice.

I have two extremely long queries that I am running on multiple tables, using an INNER JOIN. The only difference between these two queries is that they take different input values for one of the WHERE clauses, which they get from two separate DropDownLists. The results of these queries are identical, save for the time1/time2 columns.string query1 = "select Name = t1.name, time1=(SELECT hours FROM table3 WHERE street=list1.selectedvalue), t2.address from [table1] t1 INNER JOIN [table2] t2 ON t1.param = t2.param ORDER BY Name"

I have a SQL stored proc that returns a dataset to ASP.NET v3.5 dataset. One of the columns in the dataset is called Attend and is a nullable bit column in the SQL table. The SELECT for that column is this:
CASE WHEN Attend IS NULL THEN -1 ELSE Attend END AS Attend
When I execute the SP in Query Analyzer the row values are returned as they should be - the value for Attend is -1 is some rows, 0 in others, and 1 in others. However, when I debug the C# code and examine the dataset, the Attend column always contains -1.
If I SELECT any other columns or constant values for Attend the results are always correct. It is only the above SELECT of the bit field that is behaving strangely. I suspect it has something to do with the type being bit that is causing this. So to test this I instead selected "CONVERT(int, Attend)" but the behavior is the same.
I have tried using ExecuteDataset to retrieve the data and I have also created a .NET Dataset schema with TableAdapter and DataTable.

I follow the tutorial and create DAL with Dataset. I created a Table Adapter with many column, but when i Call a simple Get for 2 column only. The system display 2 column and the rest column with empty data.
example: Table with 40 column define in Dataset in DAL. I have GetMember from Dataset with 40 column, some request only 1 column (with 39 empty), some request 22 column (with 18 empty column). Will this affact the performance?

I've got very dynamic GridView and I need to allow to user to edit first column of it. After he edit first column of grid it must be updated on DataBase.Is there any ways to handle it ?My only idea is to put some changeable element to first cell of each Row so it must be able to set / get my values for each row but can't find yet any examples of it ... Additional info :GridView takes data from Object data source and all columns are dynamic (yes, maybe except first, but I add it in dynamic way) and load complete DataTable...Currently Using jQuery+Ajax methode on dynamic button but can't disable button's PostBack so with a PostBack it just disappears and dont make the event it must to make...

I have a datatable in MS SQL that has FirstName and LastName. In MS SQL I created a computed field called FullName that was ((rtrim([LastName])+', ')+rtrim([FirstName])) I created a DataSet and a Business Logic Layer. In my typed DataSet I saw FullName in the listing when I created it. I am able to use FullName in my webpage. I use it to populate a dropdownlist. However, now when I make changes to the Customer Table I am getting this error message (seen below)
Question: Should I have created the field FullName in my MS SQL Table or should I have left it alone and somehow just added a column to the DataSet and placed an expression in the FullName column? The column "FullName" cannot be modified because it is either a computed column or is the result of a UNION operator. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

The following query returns me the column name from the table in the database, and stores the column name in the grid. How can I change the column name in the grid using following code, if its possible?
DataSet p_dsInformixDataDs = new DataSet();
string cmd = "SELECT * FROM CUSTOMERS";
try
{
using (IfxDataAdapter da = new IfxDataAdapter(cmd, m_InformixDBConn))
{
da.Fill(p_dsInformixDataDs);
}
}
DataView myDataView = new DataView(m_dsInformixDataDs.Tables[0]);
if (myDataView .Count > 0)
{
GridView1.DataSource = m_dsInformixDataDs;
GridView1.DataBind();
}

I have a stored procedure in my database that sorts a dataset by distance from the specific address input by the user. The distance is created among each individual users query and the sorting of distance occurs within my stored procedure, the distance is not returned in the output. Is there a way I can create a temporary column that returns the distance so that I can give the user an option to sort by distance?

I have a gridview control on .aspx page. Situation is, the columns in the gridview control are not databound. I query the database and load the gridview control using the following code.
GridViewstockcalc.Visible = true;
GridViewstockcalc.DataSource = dataSetstockcap.Tables[0];
GridViewstockcalc.DataBind();
The gridview control shows about 13 columns from the database. But we want the user to be able to edit only one column. Rest of the 12 columsn should be read only. When the clicks one Edit button button, as usual the Update and Cancel buttons should come up. It is not happening. Only the _Rowediting event is getting trigged. Following is the code from my .aspx page. I don't know anything about template columns and not sure if I have to use that concept in my situation.
<asp:GridView ID="GridViewstockcalc" runat="server"
HeaderStyle-BackColor="#444444"
HeaderStyle-ForeColor="White"
onrowcommand="GridViewstockcalc_RowCommand" Height="150px"
Font-Size="Small" onrowediting="GridViewstockcalc_RowEditing"
onrowupdating="GridViewstockcalc_RowUpdating">
<Columns>
<asp:CommandField ShowEditButton="true" ShowCancelButton="true" />
<asp:TemplateField HeaderText="ticker">
<ItemTemplate>
<%# Eval("ticker")%>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox runat="server" ID="txtticker" Text='<%# Eval("ticker")%>' />
</EditItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="fhlb_ID" HeaderText="ticker" ReadOnly="true" />
</Columns>

I have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.

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'.

Using VS2008, and Telerik radGrid version 2010.1.519.35
I have a about 50 DNN modules using telerik radgrid and I need to display my dates in dd/mm/yy format. It is possible to do this easily in view mode, but when I switch to edit mode, it is more of a struggle. I can write a snippit of code to reformat the displayed date values to dd/mm/yy, but for inserts the user must enter mm/dd/yy.
IOW, I need to change the culture of the form to en-GB culture.
In my DotnetNuke App, I have made a change to the web.config, but it still assumes en-US format.
I am not sure whether I need to set this at web.config level, page level or at the column within the control.
