I want to Update Column of a Table where ColumnName will be DropDown.SelectedValue. Example: A set of RECORDS will be displayed from a Customer Table where CUstNo ='1234' and City= 'Chicago' and Grade ='B' Once displayed I want to Update the grade to 'A' of all those customers from the above criteria. In My case I have like 100 Columns, so in where Clause Column Names will be selected from a DropDown. In My Query, Update Customer SET ColumnName= 'some value' where ColumnName ='ActualValue' So how can I pass the ColumnName which is Dropdown Selected Value. I believe I can't give as Update Customer SET DropDown.SelectedValue = 'some value' where DropDown.SelectedValue ='ActualValue' how can I resolve this ?...
I have a gridview with an edit command button. When I press the edit button, it makes all the columns of the selected row editable. But I want it to make only few columns of the selected row to be editable...how can I do that?
I have seen a lot of things on the net on this but nothing seems to work. I have a GridView with name and other information on files stored in a database but also on a Server. I display the gridview with the files and the user selects the file to delete (row) by hitting the command field for Delete. I have an event on the gridview for code behind. Here I want to access the file name for the row selected, to be able to include it in the File.Delete statement.
Even before this I want to display the selected file name in a label back to the web page. I have tried everything including findcontrol selectedValue, etc. Nothing is working. I either get complier error, or nothing is displayed in label. If I let it go the the File.Delete step I get access error becasue there is no file name. HELP. here is screen shot of the gridview. Ignore the download button for now. That is my next headache to figure out. So based on the screen shot I want the value of log_doc from the gridview. It is in a column called file_name
File ID File Name Log Upload Date Uploaded By Download Delete 3
I have a web form where there are couple of DDL's; DDL1 and DDL2 respectively. I want the DDL2 to be populated based on what option is selected in DDL1. Also I just want to extract the first three digits of the value selected in DDL1 and use it in the WHERE clause of the SQL query used to generate DDL2.
My prob is that I am not able to extract the first three digits out of DDL1 to be compared to another field from the DB in the WHERE clause of the SQL query for DDL2.
I have a grid view that needs to be shown group wise. The grouping of the data should be dynamic and that is based on the column that is selected.
In general it should list all the rows and based on the coloumn header selected, all the rows should group by that column and should be listed under it. That also needs the template column for the check box and while group by there should be a check all option available for each group.
Even having the collapse and expand option for each groups is required.
I currently use VS 2005 and later will use 2008 and 2010, but will use the aspx code and not xaml.
i know how to find the index of selected row in asp gridview , but i need to find the index of selected column in asp gridview ?for ex:i have i gridview contains columns with header ( the header is the primary key i looking for ) , this grid contain linkbutton , i want to get the column header name on click on linkbutton ?
Scenario: I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is: I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
I have a specific requirement of extracting text and images from a specific area in a pdf file.The area might be a selected or highlighted or from a given set of coordinates.
When i went through, all the approaches are to extract images and text entirely from the PDF on not in a specified location. I tried with iTextSharp,Syncfussion,Apose but couldn figure out a better approach for this.
I'm currectly tryin to access a specific value in my database in a specific column. I'm tryin to use the primary key of the table to access the actual value in the row of that ID.
The current code:
Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?
Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?
I've a database table contains survey questions and answers. But the problem is both 'question' and 'answer' are saved in the same column(like below).
SubmissionDate Submission 2010-02-15 14:53:59.657 ***What's your pet's name?*** Lili ***Tell us about yourself*** I'm a teacher 2010-02-15 14:53:59.657 ***What's your pet's name?*** Lucy ***Tell us about yourself*** I'm a five star cook
I'd like to use a simple datagrid to display the survey result, but I need to separate the submission column into multiple columns ('question' as column name, 'answer' as data) the number of questions or questions being asked are different for each survey so they are not fixed. Is it even possible to get something like this below in a gridview?
SubmissionDate What's your pet's name? Tell us about yourself 2010-02-15 14:53:59.657 Lili I'm a teacher 2010-02-15 14:53:59.657 Lucy I'm a five star cook
