I am making updatable pages for my website. I am new to asp.net so I want to find the best method to pull one record from the database. The record will consist of page name and page text. I have test information set up in the database which works of an ID and have constructed a database connection. But I want to use a database control which willl have minimum overhead for pulling out just one record. I won't require any features such as editing or pagination. I was thiking of using the data repeater.
I have a ASP.Net project that is setup in such a way that it can be dropped into any site and "just work." All the paths are relative to the current file, not relative to the "~". The paths are determined by ThePath = this.TemplateSourceDirectory;
This is working for everything expect registering a custom control that is created and added to one of the pages. I can add the control just fine with the Page.LoadControl but I cant cast it as the correct type to access anything.
How can I add a reference to the class from within the code itself?
I have a repeater control and a text box, and likewise a button to post data to database.after i insert the data to the database in thwe click event of the button, the datalist will not update the displayed content. at the end of the button's click even, i added the code line:
Response.Redirect(Request.RawUrl)
But still, the datalist will not update automatically. What do I do next?
I have a ListView control that only displays one record at a time. I have a LinqDataSource that can return one or more records. I have a function that determines the number of records and returns a psuedo random number between 1 and the number of records returned. When the page first loads, I want to display a random record. After that, I want the datapager to move the user normally through the records.
In my Page Load Event, if Page.IsPostBack is false, I get the random number. Let's say for simplicity I have 15 records and the randon number generated is 6. How do I tell the LinqDataSource to display the record at index 6?
I have a search page. If a user enter something into title textbox and search let say it display 15 records.
If click the title of each records, it goes to DetailsPage.aspx.
What I want here is: If user click the title details of a record and leave that search page, I want to put there(On Details.aspx) Previous/Next button arrow so that the user does not need to browse back and see the search results and go to next details.
Note: I am passing ID into querystring when go search page to details page.
How to keep remembering IDs on details page of searched records on search.aspx ?? Use session or something different ? How can I do this ?
I would like to ask if there is any control act like grid to display records.The 'datasource' will be a customed class, this dataclass has List<T>, so I will populate each element by iteration into the grid.Any control can I use to work like a grid?The number of records will around 100.This control should also allow the user to select a record.
I have a dropdown box control, populated by an Access data source, and linked to a form control which renders an appropriate record detail when a selection is made. All works as intended. My issue is that each rendering of the page shows the dropdown box carrying the link to the first record, with the detail portion of the page already complete with the information for that record.
I'd much prefer that the dropdown box would carry some text, like "Click to select..." leaving the detail part of the page empty at the first iteration of the page, allowing the user to pick the first record. I can't seem to find any way around this problem with the control or the data, unless I add a record at the top of the file that carries the text.
I have one SqlDataSource control as DataSet with enable caching in one page aspx. Filtering is applied to this SqlDataSource control, so that the page always returns one record data.
My question: How to get the record data value from SqlDataSource control (one record data value) and store it as String variable?
I am using paging to my gridview (pagesize=4) . now i am in (X) page and i want to get (X+1) page top record or (X-1)page bottom record , how i can get .
I have a delete button bellow my gridview and I want a pop up to show when no record is selected and tell the user to first select a record. The button click event would show the pop up, but my gridview data blanks out.
public static class PageExtensions { public static int GetUserId(this Page targetPage) { var user = Membership.GetUser(targetPage.User.Identity.Name); return (int)user.ProviderUserKey; } }
Now in a page I need to use this method in a static WebMethod, so I have added another 'extension method' to PageExtensions:
public static int GetUserId() { return (int)Membership.GetUser(HttpContext.Current.User.Identity.Name).ProviderUserKey; }
and I call it as follows in my WebMethod: PageExtensions.GetUserId()
I want users to select a record in the GridView and then have that record open up in the Detailsview. How would I go about getting these two tools to communicate?
i have design a web application having suppliers table using SqlDatasource..
i have a master page in my design and other form are bound to a context menu..
Now i have displayed the records in the gridview..all i wanted is after i select a record in the gridview it will display the selected record in detailview from another aspx form..
i was able to create the link to another aspx form but the data that it display is the first data from the gridview not the data that i select.
i have to make this form in my asp.net project [URL] so a tipical master/detail relation in the top of the form there a datepicker wich correspond to master table+ other controls like the customer the grid corespond to the details table (order details table) i want to add records to the details table in the client side and then send all the records in one operation to the server - the problem is how to get the correct primary key from the master table ? - how to insert details record in the client using a gridview control
First of all, when using the GridView control with Delete enabled, when I delete a record is the event handler in the code behind file handled before the record is deleted or after? I need to obtain a counter value that I have set up in the record before it is deleted so that I can decrement all of the counter values that followed it. Is the best way to do this to open a connection in the Delete even handler and take care of it by code, or is there another way to access a column value from the GridView control that would simplify the process?
I need to access a TextBox control inlistview. I have tried the following code behind but I don't retrieve the correct textbox. A snippet of the code is as follows:
I found a write-up somewhere about the multi-handle slider control and in the post there were the following javascript lines:
slider.add_value(value); slider.add_drag(value);
Slider, in this case, is my slider control... but how did the person know these two methods exists? Is there an API guide somewhere for the Ajax Control Toolkit?
I have a user control written in C# in a Telerik ajaxified page. I wrote a context menu using RadContextMenu and everything works fine except one of my menu items is "refresh". How can I refresh my user control from javascript? Basically it needs to some how force the TelerikAjaxManager to refresh my control.
I have couple of controls in the page. I need to modify these value in Page method. How can I do that?. When I modify those values in page method should reflect in page?
I need to configure a property of a custom control I wrote, specifically before the control calls OnInit. If I assign it as part of the ASPX file, it naturally works, but if I instead move the assignment to different parts of the code-behind, it will throw an error for having an empty and invalid value. The following is what it looks like when functional in the ASPX page.
The property in question is FilterString, which is just a simple string. It should be noted as well that the FieldName property (inheritted from the control's base class "BaseFieldControl") would also throw an error if it is not initialized, but if I set FieldName in the code behind's OnInit method, it works correctly. FilterString is not so, it won't actually be assigned. So I know that some methods for certain properties will work for setting the property's value, but it won't always work. I tried placing it in OnPreInit as well, to no avail.
I am taking a dynamic assignment approach because the functionality of this page needs to be replicated for a number of different lists, and the FilterString and FieldName properties will differ in every case. Rather than write half a dozen mostly-identical aspx pages all with the same code behind but differing just in what those two properties are, I figured it would be wiser to use the page's query string and some derived parameters to set those properties dynamically. As such, what methods are available to accomplish this task?
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control.
