Data Controls :: Filter GridView With TextBox Using SqlDataSource FilterExpression Containing Apostrophe (Single Quote)
Jul 17, 2015
So I found an example on how to search gridview using filterexpressions on this site (Filter GridView with TextBox using FilterExpression in SqlDataSource in ASP.Net), but now if I try to search with an apostrophe in the textbox, the code fails.
Here's the link to the the article/source - [URL] .....
I have a record in gridview contains string with special character like single quotes( ' ) etc..I've a edit button in gridview when i click on edit button of any record of Gridview then corresponding record shown to text box.
But on that time single quote looks like below ....
Before edit button click string in gridview cell, a testimonial or show consists of a person's written or spoken statement
After edit button click string in textbox, a testimonial or show consists of a person's written or spoken statement but when I click update button shows following error :
"A potentially dangerous Request.Form value was detected from the client (ctl00$ContentPlaceHolder1$tb_comment="...f a person's written or sp...")"
What is the solution so that single quote shows as it original format as it looks in gridview cell when i click on edit button.
In my database, there is a column "summary" with single quot in it.I am fetching this data inside Gridview. Data is shown inside Gridview as:
<summary>" I want single quot to be shown inside Gridview as (')for that I tried to change the code as below: <asp:GridView ID="GridView1" runat="server" Width="100%" BackColor="White" DataKeyNames="IssueId" AutoGenerateColumns="False" AllowPaging="True" PageSize="8" CssClass="Grid" OnRowDataBound="GridView1_RowDataBound">
I have a database which holds the scores in the league for my local table tennis club. There are 3 divisions. On the admin page, I want the admin to be able to add teams and edit the scores. For each league, there is a seperate gridview. How can I use just 1 SQLdatasource to filter the records for each gridview if all the teams are in the same database with the division next to their name? I'm new to web development.
I get the Erorr: Input String was NOT a correct format.
The first three controlparameters are STRINGS and they work fine.
However the last two populate the controlparameter from text boxes that can only accept numbers and decimal point.
First the text boxes for {3} and {4} string parameters in the SQL filterexpression: [Code]....
And then the SQLDatasource control parameters[Code]....
The last two control parameters are the ones is question as they feed {3} and {4} parameters in the filter expression, NOTICE how I set the type="double".The data input is expected to be like 152.25 or 3.6 or 4 etc,So why am I getting this error: [Code]....
I have a stored procedure that returns 3 tables within the single recordset it returns. If I set a SqlDataSource to get data from this procedure, it works, but it only returns the first table. I want to have a GridView display the data from the 2nd or 3rd table using a SqlDataSource, but I can't figure out how to specify a particular table.
While there are some posts discussing this out there, I can't get a definitive answer about whether or not this is even possible (?). In a worst-case scenario, I can create another SP that only returns the 3rd table - but that creates a little maintenance headache that I would prefer to avoid.
In this test application, I am filtering by two ControlParameters. As you can see in the first codeblock, both parameters have a default value of %. This code works great. However, in the second code block, please note that the Default Values are eliminated. The second code block works as long as neither Textbox's text is blank. For some reason, when .NET evaluates the filter expression and inserts "" into the expression, it seems to bug out and case none of my results to be filtered.
I am able to verify this behavior by setting the defaultvalue="" for each ControlParameter.Obviously I have found a workaround, but I would like to know why the FilterExpression breaks down when an empty string is provided.
Code Block 1:
<asp:SqlDataSource ID="Customer_Data" runat="server" ConnectionString='<%$ ConnectionStrings:connectionString %>' SelectCommand="SELECT Station, StoreFront, CustomerID as CustID FROM vStations" [code]...
SQLCommand cmd = new SQLCommand("insert into customers name values ('"+textbox1.Text+"')",conectionstring); cmd.ExecuteNonQuery();
now when people enter a (') single quote, this doesnt work. how do i avoid this error as this is driving me nuts!! i cannot prevent users from entering single quotes as names like "O'Connor" contain a single quote. parameterized query doesnt seem to be the best solution as it involves loads of coding and will involve huge changes in the code. as its not a fresh app im making... can some modification in the code above so this can be avoided?
In my asp.net Page I am using gridview. I am binding the gridview on page load and on paging event with one method. suppose as Bindgridview1();.
There is one search button for searching the records of user with different method suppose as Bindgridview2(); .
when I am searching the records with Bindgridview2(); paging doesn't work and directly bind with Bindgridview1(); which is on page load when I clicked next page.
I have textbox that searches for first or last name. Result show in gridview. But when add value in text box and push my button Find nothing happen. Here code:
I have been stuck on an issue that is driving me mad and I bet its simple. I have a Textbox with a gridview and a LINQ statement in code behind that populates the data source of the gridview at page load.
The Textbox is used as a filter for the where clause in the Linq statement. All works as expected however I want to be able to use more than one word as a filter. This is the problem. I take the textbox string and convert to an array
Dim aryTextFile() As String = SearchString.Split(",")
But I need to figure how to pass the values of the array as parameters for the Linq Statement. I need to return all rows that have either a match for LocationName AND/OR Address AND/OR City. I thought of something like this but it fails.
Dim db As New DCLocationsDataContext Dim q = From t In db.Locations _ Where t.City AndAlso t.LocationName AndAlso t.Address Like aryTextFile _ Select t GridView1.DataSource = q GridView1.DataBind()
i want to filter the gridview on textchange in search textbox. if i press "a" the gridview should filled up with record starting with "a". i have some code
SqlDataSource1.SelectCommand = "select * from DeptMaster where DeptName like '" + TextBox1.Text + "%'"; SqlDataSource1.SelectCommandType = SqlDataSourceCommandType.Text; GridView1.DataSource = SqlDataSource1; GridView1.DataBind();
its working while leaving the textbox but i want this code should execute on keypress event.
I'm sure this is something simple that I have overlooked, but whilst configuring my SQLDataSource, I have tried to add a where statement onto a column in my datatable that has a data type of 'bit'. I have tried typing 'WHERE Answered = "0"' for false and also 'WHERE Answered = "false"'. The data source doesn't return any rows to my detailsview with either statement.
[URL] .... I Need to search record from GridView by using the textbox but not want to configure this with SQLDataSource Manually (Front End) therefore how to filter gridview from Codebehind.
I am trying to populate an (editable) gridview in ASP.NET with a table from SQL. I have a SQLDataSource set up for this. I also need to have this gridview be filterable based on parameters entered in textboxes. I have tried using ControlParameters for this and it works but the problem there is when all textboxes are empty I want it to display all results in the gridview. What it does is display nothing because no entries have parameters that equal "". Is there an easy way to do this that I am missing or is there a better way to go about it other than a SQLDataSource?
which doesn't work because of the final apostrophe in the notation i.e. %>' It truncates after the word e.g O'Neil Someone becomes O' which is incorrect.
This works like a charm: value='<%# DataBinder.Eval(Container.DataItem, "Name").ToString().Replace("'", "'")%>' which isn't good practice as I don't want to hardcode '
I have a gridview with textbox and that textbox is for searching. My question is do you know how to search with all fields in gridview.For example: I have a gridview contains, FIRST NAME, MIDDLE NAME, and LAST NAME, and if I type in the textbox the gridview will automatically get what I've inout in textbox.
I have a parts table (ID, PartName, Category). I have an Engine table that has 10 columns to specify the 10 main parts that comprise the engine (EngineID, PartA_ID, PartB_ID, PartC_ID...).
I want to make only one trip to the DB to pull all the rows, then filter by category for each PartA, PartB, etc ddl. how to do this?
