Blank Gridview Cell Populates " " Into Textbox?
Nov 6, 2010
I've noticed that when i populate textboxes from a selected row in a gridview that if the field is blank it displays " " in the textbox.
Here is the solution I came up with. I check each cell before adding it to the textbox.
I get the feeling that I'm either doing something wrong to have this problem in the first place or that there is a better way to handle this.
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
//// Get the currently selected row using the SelectedRow property.
GridViewRow row = GridView1.SelectedRow;
// Load data from selected row into textboxes
if (row.Cells.Text.Trim() != " ")
txtEditCust_ID.Text = row.Cells.Text.Trim();
the description which is comming from database has number of <p> </p> these tags so my page is occuyping large amount of blank space. I want to remove all those blank tag which are coming at end of page How to do this?
I am trying to check if a cell in a gridview's selected row is blank. Nothing seems to be working. See the different options I've tried below. When I check an empty cell's text.length is tells me 6 ?!? Is that a tab and a space?
Or should I say what is the value of a blank cell in a gridview?
I want to save updated values to database, But when I try to access values using string strs = ((TextBox)TwoHeadedGridView1.Rows.FindControl("txtStandard")).Text;
It always returns me the blank value for all the rows, Same thing happens for dropdown list it returns me originally selected value i.e. value selected at the time of writing dropdown box, there are no duplicate ids present on my asp form , This is my first interaction with customizing gridview, I want to somehow make it run,
I am using VB code. I currently have a dropdownlist populated with Item numbers from a database. When the user selects item number, it retreives other field inforrmation from the table and populates other textboxes on the form. This all works fine. The problem is that the user wants to be able to type the item number and then when they tab off the field for it to retreive the other field infomation to populate the textboxes. The user has to enter lots of item numbers and does not want to search a dropdownlist. I would like to have a textbox where when the user starts typing the item number it displays possible choices to select from or the user can type in the full item number. Just like how when you type in the Google search box on their main page. my existing code which is below:
I want to edit a cell in the gridview. So that when i click on any one of the cell in the Gridview itemTemplate the praticular cell only should converted to TextBox insted of converting entier row to text box. Is there is any method is there to access the Edit Template of Gridview?. or else any other method is there to achive this?
i think that the the subject can explain what i need, it's about adding a TextBox control with the code behind into a GridView, and also about how can i retrieve entered data after submitting, im using C#,
Basically, the user Selects a row on GV that executes an Insert into a table the GV cell values of the selected row.
The SQL field data type is varchar. If the GV field is Null, the Insert adds the value to the SQL field. How do I keep the @nbsp; from being displayed in the cell of a data control when it is called at a later time? Do I add some more asp to my control parameter? do I add some vb code behind? Here are some relevant code snippets of existing code.
I have 2 pages both are using Gridview and implemented in C# asp.net.
On page 1, in the Gridview (ie, Edit, Delete enable) when I click Edit so I have a Textbox which allow me to edit the text in the textbox that populated from the database and next to it I have a button when click I need to open a page 2 where user can select a row (ie, page 2 also use Gridview, Select enable and use different datasource ), once user select a row I need to get the value row.cells for example and put the value into the textbox in page 1 and page 2 close itself. the purpose of page 2 serve as a look up table and for user to select a row, then display that value in the textbox in page1.
I can get the value on page 2 when user select a row but I dont know how to implement such when user select a row and get the value on page 2 and put the value into the textbox in page 1 and page 2 close itself.
I have a gridview each line has 4 linkbuttons - Edit , Update , Cancel , Delete and a few columns with data...For example TeamName and TeamEmail, and a hidden column that contains a validator (for ease of validating controls that are found on the same row , same naming container)
When Edit button is Clicked , the specific line goes into editing mode , Texboxes are created for TeamName and for TeamEmail .
I create dinamically (code behind ) a new textbox that reads the value from the TeamEmail textbox , i give it a new id (let's say "Email") , add that email to the controltovalidate property of my validator , and call the validate() method of the validator.
Everything works fine when i modify the value in a worng format , the validator err message appears , when i modify the TeamEmail value to a good email format , the validator property isvalid becomes true , and the update is running , but my textbox is empty :( updating the TeamEmail value to null.
This is some bad code but hope you understand what i meant :
I want to know how to create a textbox in VS2005 where in the box I would type the name of my favourite sports team and once I've pressed the submit button a Gridview table would populate displaying the the name of the team and a image of the club/team shirt.
I have an application that populates a gridview based on criteria in a table. I have another table that holds data to be omitted. I will post the current LINQ code and also the end result SQL code that I need to figure out in LINQ. Below is my code:
Current LINQ Code: Dim TestType = (From test In db.Table _ Where test.TypeId = TypeID _ Select test.Id, test.Title)
I have a grid view populated with some data included bit fields and I made an export to excel function For each row i need to check the cell with the bit value to change the cell color, but the cell is always empty, even if is the field is set to False or True. foreach (GridViewRow row in gv.Rows)
I'm having a weird problem where the GridView cell that I'm programmatically updating turns grey, and throws a null error when attempting to save row. I have been searching all day and have not been able to find a solution. I'm guessing there is a problem with my code, so here it is:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
In my Website, I have a gridview which has datasource dynamically bound from database table. Requirement:
Now I want that when a user clicks in a cell of the gridview it becomes editable and he can edit the cell values and update the database accordingly. I dont wish to use the in-built edit, delete and update buttons of gridview. How can I do that?
I have a simple issue..the user types his/her name in a textbox. Accidentally if a space is entered after a name or before, is it possible for me to trim it while accepting and not raise any error (which actually arises when the textbox is empty)?
