Forms Data Controls :: E.command Argument Is An Empty String?
Nov 22, 2010
When my LinkButton1 button is clicked in the gridview below, I would like the Gridview1_Rowcommand to assign the ID1 to the index variable. I am getting a "Input string was not in a correct format." error. The e.command argument is an empty string
I got this check box on my page..if I need to assign these two values of CommandArgument in CssClass attribute ie <%# Eval("UserID") %> and <%# Eval("IsB") %> to two strings in my code behind..How do i do this?
protected void chk1_OnCheckChanged(object sender, EventArgs e) { string s1 = "Need the first value from Command argument here"; string s2 = "Need the second value from Command argument here"; }
how do i fetch those command argument values passed in CssClass attribute of checkbox?
What I want is here that ; I want to specify the button's command arguments according to selection of radio buttons which is in the same group. I want know that which price type is selected return or one way.
i have a grid with template feild with two button's Accept and Deny and Command Name="update" and command argument ="Accept" and command argument2="Deny" now the problem is everytime when i click any Button it gives me first row data see my source
I want to know how we can get the command argument of a Image button in Javascript.
Scenario:
I have a grid in that I have image button in template column.on click of each image button i have to redirect to another page with respective ID fields.
i'm trying to issue a select command in my app soi could execute the command and retrive the data into a string variable.the problem is that this command is overloaded with DataSourceSelectArgument and i can't figure out what it is.i'm using sql server express and when issue a n insert command for example sq.Insert(); i have no problems.this the command that's holding me:
SqlDataSource sq = new SqlDataSource(); sq.ConnectionString = ConfigurationManager.ConnectionStrings["CustomerDatabaseConnectionString1"].ToString(); sq.SelectCommandType = SqlDataSourceCommandType.Text; sq.SelectCommand = "SELECT * FROM CustomerTable where customerID = 1"; string result = sq.Select(some overload that's stopping me);
but when I click on imagbutton it didn't do any thing..I put break point and checked @ID value that was "_page" and I checked IMG Delete. Command Argument value was "".I used .CommandArgument for Linkbutton in other page I don't know is it right to use it for imagebutton?
I have a gridview with two bound fields. On clicking a button i want to display the values in first row of gridview in two textboxes. But if gridview cell is empty i am getting the text in textbox to which the value of cell is given as -' 'i know my problem will be solved if i use the template fields instead. But i want a solution while maintaining the bound fields ,if any.
The user control is a series of 5 buttons (similar to a radio button list) where only the latest button is recorded. I.e. if you click button 3 and then button 5, button 5's value is stored. The repeater can have a number of usercontrols, varying in numbers. The typical number if 5/6. When the submit button is pressed, the form needs to collect information from all user comtrols I.e. the database id of the control and the final value. The values will be processed later. At this point i'm looking at the best way of validating values, ensuring that all controls have a value and passing them onto the buttons command argument.
string s = "" when I click on the DeleteImage1 button in the EditItemTemplate row.Cells[2].Text is an empty string in gridView_RowCommand (3 buttons inside an EditItemTemplate)
I am using c# with VS 2010 and dynamic data. I have a gridview that is populated by scaffolding. I then want to use the "Delete" command on the row. While the command works fine, it does not seem to know the datarecord has child tables in a one to many relationship, thus it wont properly delete the child tables before deleting the parent table. Which is fine, i can call some linq to sql to get the table id and delete all of its children before the parent table is deleted. Odd thing is, the Gridview is retruning "" emtpry strings for the cell that has the table uniqe ID.

why i am getting a empty string for "GridView1.Rows[rowIndex].Cells[2].Text"?
we have a AutoGenerateColumns-enabled WmxDataGrid in which we are able to update table rows in a DataBase connected with a SqlDataSource.
Each time we clear a field an empty string is written to the database where we want to write DBNull values.
At the moment we generate the update string via UPDATE... SET.. and the SQL Server function NULLIF(value, '').
Works proper but when I want to add the values to e.NewValues in BeginUpdate event I'm not able to read the values from the auto generated text boxes. How do I do that? Is there an easier way to automatically convert empty strings to NULL values?
how would i do my Gridview delete command like a update command?
im using a datasource... and my delete command is like my update command... so i can change the status into "INACTIVE"...
DeleteCommand="UPDATE ACCOUNT_MAINTENANCE SET am_status = 'INACTIVE' WHERE (accmain_no = @accmain_no)"
UpdateCommand="UPDATE [ACCOUNT_MAINTENANCE] SET [account_type] = UPPER(@account_type), [min_deposit] = @min_deposit, [min_capital] = @min_capital WHERE [accmain_no] = @accmain_no"
when i press my delete command at gridview... the status changed into "INACTIVE" but when i refresh or press f5... it automatically update the status into "INACTIVE" also...
When I click on the Alphabets it will show the details of a player...however, when that particular letters has no details of the player..I want to show."No results can be found"..Is there anyway to do it?
I have a datalist which will display a list of groups from the database. In every group record, i have a button binding to it, and i give it a commandName call "joingroup" . When a user actaully clicks on the button(btnJoinGroup), the commandName fires. The problem i am facing now is, whenever i click on the button, i get this error below:
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
I have pass following SQL Query to the through ObjectDataSource
[Code]....
And I am passing parameter through QueryString and My idea is like when empty string is pass it should show me all records but when I am passing empty string ObjectDataSource is making NULL and I am not getting desire result
