Forms Data Controls :: How To Create Selectcommand At Runtime
Sep 30, 2010
I build a DetailsView and assigned datasourceID= SqlDataSource1
I bulid select command at runtime.
string selectcmd = "SELECT * FROM CDInfo WHERE CDID=@id";
SqlDataSource1.SelectParameters.Add("@id", Request.QueryString["id"]);
SqlDataSource1.SelectCommand = selectcmd;
//The only problem is that I try to call the select method
//but the compiler tell me I have to add a DataSourceSelectArguments
SqlDataSource1.Select();
//I don't know what argument to add, so I put DataSourceSelectArguments.Empty
// But it says variable "@id" must be decleared
//I don't Know what's going on.
There are cases where I have to change this query dynamically at runtime, so I do the following:
SqlDataSource1.SelectCommand = sql; // 'sql' is the new query GridView1.PageIndex = 0; GridView1.EditIndex = -1; GridView1.SelectedIndex = -1; GridView1.DataBind(); updatePanel.Update();
This works just fine actually, but when I click the pagination controls, the result set defaults back to the SelectCommand defined in the SqlDataSource1.
I have a SQL query that returns about 5-10 records. For each one of these records I want to query another table using values in that row as parameters and create/populate a GridView. Can I create these GridViews and SQL connections programmatically in a for loop? I mean, I can't just plop ten GridViews and SQLConnections on my page at design time because I'm not certain how many rows will be returned in the first query. What should I do?
I'm trying to create multiple gridviews for a number of individuals based on a selection from a dropdownlist. The user will select his choice from the dropdownlist and from there a query is run to find the number of gridviews to create. Each gridview will also have its own data to bind. I believe I have most of it, I just can't get the gridview to show up. My thinking is to create the labels, then insert a gridview, bind it, and then repeat the process all over.
How can I access the datalist at run time to create, a table layout but with the first cell having a rowspan of 2? Below is the HTML source code to demonstrate.
In my application, I am using DataList. In Item Template I added One GridView and SqlDataSource to populate data in GridView. DataList having one DataKey field, I want to pass this DataKey Value to the SqlDataSource as Parameter.
This grid looks great in the browser, but when printing, the date is duplicated - one w/ the correct format and one w/ the full datetime format (including hh:mm:ss). I've tried converting the datetime in the Select query, but keep running into error messages.
With asp 2.0 and vwd 2005, I have a page with a radiobuttonlist, textbox and gridview with edit/delete. Using the radiobuttonlist, the user selects a search type and then enters the criteria in the text box. the click event of a submit button checks the rbl.selectedindex and chooses a sqldatasource.selectcommand with the where clause getting its criteria from the textbox. The gridview loads the data, but the edit/delete are not working. Code and relevant markup is below
I have a question involving the ItemDataBound EventI have a linkbutton, btnOverview, that is displayed in a DataList ItemTemplate.I would like to select 1 of 2 imageurls for this button based on the value of haseOverview which is a field returned by the SelectCommend of the sqlDataSourcefor the DataList. I am not sure of how to reference this field.I have highlighted what I think is he relevant code section below.
I've figured out how to create the controls in the format I want, but now I am confused as to how create more than one set of them. I set everything to new and increment the names of each control, but it's only updating the one set. Here is my code:
I was wondering is it possible to create a css class at runtime?
I am unable to use the traditional method of doing so as one of the attributes need to be loaded at runtime.
As I am using the Coolite Toolkit, whenever i need to use a custom image onto one of the controls, the custom image path needs to be loaded in via a stylesheet class.
