Forms Data Controls :: Handle Multiple DataKeyNames?
Mar 17, 2010
I have these line of code:
[Code]....
When i debug i get an error that says: 'System.Data.DataRowView' does not contain a property with the name 'job_id'and sometimes 'System.Data.DataRowView' does not contain a property with the name 'pub_id'I need to get the appropriate value for the selected row. GridView only output Jobs results or Publishers results, the problem is when the user clicks select button beside the record, i get the error i mentioned above.
I have a GridView with edit/update functionality. While updating, I need to get some hidden values saved in DataKeyNames. How to get the values of DataKeyNames via RowCommand? I have tried the following code via RowUpdating and RowCommand, but it gives an error in e.CommandArgument.
I have two listviews. What i want to do is that when the nested listview emptydatatemplate shows i want to put a hyperlink with a querystring in it, the id in the querystring should be the fk in the nested listview. Is it possible to bind the hyperlink with the id in codebehind? I use two object datasources. Does it matter where i put the nested listview now i have it in the parents itemtemplate. Also it seems to be a problem to set the datakeynames in the nested listview, what could be the reaso for that.
From what I understand within the Gridview Object you can have many datakeynames.
I have the field like this DataKeyNames = "id1, id2"
However, i don't know how to access the DataKeyNames individualy. For example. How do you access the first ID for the for a given row or the 2nd ID for a given row????
i'm getting error on finding control from grid's row.control is an imagebutton which is placed inside a template field.my requirement is if add to cart button is clicked and if that particular book has its volums then it should show message that you need to see its detail and then after selecting its volume you can add it to cart...but i'm trapped in where i'hv to attach bookcod with querystring which is in datakey names of grid. The datagrid has one column only and thats template field..
I have two columns in my Gridview marked false for the visible property but which are clearly listed in the DataKeyNames that are still getting set to null in my database table on update.
The first one is a column MId# which is a type int. It starts as 0 but on edit is turned into null. The Second is RequireSKU which is also converted to null.
When the page is displayed have labels, textboxs, and dropdownlists on top part of the page then the gridview at the bottom with the page numbers at the bottom of the gridview. Create the columns and add data to the gridview programmatically with several hidden columns. Use DataKeyNames on the source page and use DataKeys in VB.Net code behind to get data from the hidden column cells of the selected row. On the first page when a row is selected, the textboxes and dropdownlists have thecorrect information from the gridview hidden columns. When select another page from pages numbers at the bottom of the gridview and select a row from the new page, get theinformation from the hidden column from the first page andcorrect data from the columns that are displayed onnewly selected page.
Since I am using 2 DataKeyName is Gridview, so I have to pass both the DataKey while deleting Row from Gridview(using "Image Button" of Gridview).I tried it using below lines:
string name = GridView1.DataKeys[gvrow.RowIndex].Value["G_Name"].ToString(); string id = GridView1.DataKeys[gvrow.RowIndex].Value["Param_ID"].ToString();
I am did Gridview delete and rebind data using json and jquery like this
<script type="text/javascript"> $(document).ready(function () { $(".deleteGridRecord").click(function () { //Get the Id of the record to delete var record_id = $(this).attr("id");
[Code] ....
But i want to set DataKeyNames properties of grid view in above code dynamically how can do this....
what are the ways of handling multiple web forms data for saving into database after last form or editing data and saving back to database after last form is submitted.Previously I have used wizard & panels in a single form and also has cached data from multiple form to save when last form is submitted. Are there some better way to handle multiple web forms data for saving and editing ?
I have a form which allows users to modify data, what's the best way to handle that so if two or more users try to make an update i get the data in there properly without overriding the new stuff. for example if name and bday are in the form, user1 changes name but not bday, same time user2 accesses the form, the original name and bday are there, user1 saves, but when user2 saves, since he had the original name value the original is saved over the first.
I am trying to create a method that accepts multiple types of controls - in this case Labels and Panels. The conversion does not work because IConvertible doesn't convert these Types.
public void LocationsLink<C>(C control) { if (control != null) { WebControl ctl = (WebControl)Convert.ChangeType(control, typeof(WebControl)); Literal txt = new Literal(); HyperLink lnk = new HyperLink(); txt.Text = "If you prefer a map to the nearest facility please "; lnk.Text = "click here"; lnk.NavigateUrl = "/content/Locations.aspx"; ctl.Controls.Add(txt); ctl.Controls.Add(lnk); } }
I'm creating a site that will offer several different services (blogs, videos, images..), all under the same site.
Each service will use a separate database and all services must use the same membeship info. Users will only need one login to access all these services.
For the membership database i will use the default aspnetdb database.
There are two ways i can think of:
1) Use a join-query between two databases, each time i want to show some service records per user.
2) Create a custom membership-info table in each service's database, and keep it in sync with the master membership table in aspnetdb database.
I've inherited an SQL table with a column named "product_codes." It contains 1 or more 4-digit numerals separated by commas (for example, the first record in the table has this in the "product_codes" column:0010,0810
There's a second table containing those product_codes and their corresponding names in a column called "product_name"
I'm trying to set up a FormView that will display an individual record and allow the user to update the record. But when attempting to display a record that has multiple values in the "product_codes" column I get an error, presumably because it can't map the product code to the product name.
It should be simple; although I'm having a hard time to figure out the best way to do it. I've MVC2 pages with multiple forms on the same page having different functionalities.
What's the best way to handle this; including the MVC2 way of validation from the model?
I use a ListView along with an ObjectDataSource tied to a business object. This object is defined as follows:
public class Employee { public int Id; public string Name; }
When I try setting the DataKeyNames property of the ListView to Id, ASP.net blows up and says: DataBinding: 'Employee' does not contain a property with the name 'Id'. However, when I change the object to that:
public class Employee { public int Id {get; set;} public string Name; }
It works!!!I couldn't find any documentation about this behavior. Why is it not accepting a simple variable for DataKeyNames and instead it insists on a property?
I have an asp.net application in which I have a parent form and in that on load I am adding sub forms dynamically having a submit image button..
When I am clicking the button of one form then I am able to read the hidden variables using request under parent form .But on clicking the second button the hidden variables of parent form are having null value although i have assign the value to them using context variables.
how can i handle mulitple form action for same page
I have a page in which i need to show data in the form of a grid. Each row in the grid is made up of 2 sub-rows, the first sub-row consists of a dropdown, a textbox & a textarea. Whatever is entered in these controls should be displayed in the second sub-row in the form of labels at runtime (i.e. using javascripts)
There can be multiple rows like this. The grid would have a max of 30 row, not more than that. create this which one would be better, in terms of performance & complexity, a GridView or a DataRepeater?
I have gridview with 3 columns and one textbox in each column.
