Forms Data Controls :: Search For Gridview On Eventhandler?
Sep 3, 2010
I was woundering if there is a way to seach for a gridview on event handler.? I have three gridviews in which i can insert from and on my insertbutton codebehind, I want to check the gridview i am using so i could get the datakeynames for insert into the database.
I am banging my head with gridview at the moment. There's a problem I just can't get my head around. I'd be very greatful for any advice given. I have a function that creates a DataTable with three columns and four rows. In each of the cells I set the text to a random number through RowDataBound event. I would like to just make the cell clickable and have a code-behind function that gets the position of the cell (column, row) and the value of the cell when the user clicks it.
I have a gridview I create dynamically and one of the columns is a checkbox. I need to set an event handler on this control for checkedchanged. everything appears to work fine except for one thing....even though I can see my WebForm controls they are all null..(even thogh I know they are not) So I basically cant do anythign to the controls in the event handler. Here is teh code I use to create teh dynamic column in the gridview.
EtscUtilsUI.ALMSSECSRV.EALMSAppRoles ealmsapprole = new EtscUtils.EtscUtilsUI.ALMSSECSRV.EALMSAppRoles();//Thsi is the webform code behind partial class. CheckBox chk = new CheckBox(); chk.ID = _columnName; chk.DataBinding += new EventHandler(chk_DataBinding); //Attaches the data binding event. chk.AutoPostBack = true; chk.CheckedChanged += new EventHandler(ealmsapprole.Dyn_CheckChanged); container.Controls.Add(chk); chk.Enabled = true; This is the code for the event Handler internal void Dyn_CheckChanged(object sender, EventArgs e) { string err = ""; try { if (lblAppID.Text != "") }
that label come back as null event though a previous event set its value successfully if I try to reference the gridview itself I get the error Object reference not set to an instance of an object.
I made a usercontrol consisting of an AJAX tab control, a textbox, and a gridview. The gridview is pulling data from a SQL database. When the gridview is outside of the tab control and I begin to enter text into the textbox, quicksearch begins to filter the information in the gridview. When i put the gridview and textbox inside an AJAX tab control quicksearch does not work. How do i need to structure the textbox and the gridview on an ajax update panel to get it to work?
trouble with the gridview.First at all, I needed a dropdownlist in my gridview, I got it, but now I would like to add a new column with a linkbutton or link that send me to another page to edit an especific item (users in this case), but when I add the column and use templates to put a linkbutton I cannot add event to every linkbutton :(I do this in:
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound Dim row As GridViewRow = CType(e.Row.Cells(0).NamingContainer, GridViewRow)
I would like to run a search and show the result on the grid view from my database.The search have many criteria , means user can search by first name and last name and amount .... Then i would like the user to be able to be able to edit and delete the records.And finally i would like to show a row showing the sum of some fields.
currently i have the following code, but there is a problem over the edit bitton, it's not showing the edit mode of the grid view [Code]....
i know it seems like i have asked this question before in my previous post but does any one know how to find a control in a gridview but it must be done in the SelectedIndexChanged event ....the previous method i was given only seems to work in the onRowBound method...If possible is their a way you can determine which button was click since i have more then one button in my gridview
i just want to place a text box and if i enter any value in that, it must filter the exact match for that and must show the details in gridview. how can i do this. my control is firstname, i am going t ofilter using firstname
I have a grid view and I was doing search based on the data user entered in TextBox. I can able to highlight the data in GridView but I would like to navigate to that row instead of scrolling and searching for the highlighted record.
Here is my code to search for a record in gridview.
I build a serach function just using SelectCommand and SelectParameters, i.e.
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:mprojectConnectionString %>" SelectCommand="SELECT * FROM [publication] WHERE ((([character] LIKE '%' + @character + '%') AND ([type] = @type)) OR(([f11623] LIKE '%' + @f11623 + '%') AND ([type] = @type)) OR (([f1character] LIKE '%' + @f1character + '%') AND ([type] = @type)) OR(([nortonoxfordnumber] LIKE '%' + @nortonoxfordnumber + '%') AND ([type] = @type)) OR (([nortonoxfordtext] LIKE '%' + @nortonoxfordtext + '%') AND ([type] = @type)))"> <SelectParameters> <asp:ControlParameter ControlID="TextBox1" Name="character" PropertyName="Text" Type="String" /> <asp:ControlParameter ControlID="TextBox1" Name="f11623" PropertyName="Text" Type="String" /> <asp:ControlParameter ControlID="TextBox1" Name="f1character" PropertyName="Text" Type="String" /> <asp:ControlParameter ControlID="TextBox1" Name="nortonoxfordnumber" PropertyName="Text" Type="String" /> <asp:ControlParameter ControlID="TextBox1" Name="nortonoxfordtext" PropertyName="Text" Type="String" /> <asp:ControlParameter ControlID="DropDownList1" Name="type" PropertyName="SelectedValue" Type="String" /> </SelectParameters> </asp:SqlDataSource>
I am also using a dropdown box and a textbox for people to search within a particular area from the dropdown list.
Now, I would like to be able to highlight the keywords in my gridview table. I searched around on the Internet and found a lot of samples, but they are all related to the Gridview <templates>, however, I am using <BoundField> and sqlDataSource.
I just cound not figure out how can I add this highlight function to my current search function?
So, one of my end-users would like the option to search for a keyword and have all of the records that contain that keyword show up in a gridview. Is this possible? How would I do this? Are there tutorials somewhere?
I have a gridview that populates from a sqlDataSource I added a textBox and a button to input company name in a textBox and click the button to search. Once the row with company is found I want to update it, but when I click update in this row, the gridview displays all of the rows, and instead of the one fromthe search results, the first row at the top is displayed in update template.The GridView first is populated from a static sqlDataSource (EditDistributor), that displays all of the columns in a table.
I want to give search functionality in grid view. To implement this i am following the below link [URL] but I am getting following error The name 'MSCD' does not exist in the current context Iam using the following code
I want to search a gridview....For eg: If the gridview has three columns col1,col2 and col3 and it contains 3 rows of values(a,b,c,.....), I want to search a particular column for a particular value..For eg: If col1 contains value 'a', I want to replace 'a' with another value 'a1'..
I would like a gridview (using entitydatasource) to display the search results based on values provided in textbox txtSearch and dropdownlist ddlsearch. My search controls are as follows:
[Code]....
My entitydatasource is:
[Code]....
My gridview is written as:
[Code]....
Codebehind file contains:
[Code]....
I am a newbie at entitydatasource and have a few questions:
1. Currently, the gridview doesn't render. Why is that?
2. How do I wire up the gridview to grab the values of ddlsearch and txtSearch and return results using those values from my entitydatasource?
3. Ultimately, I want to encapsulate this gridview in a wizard step wherein the user checks items they want and those checked items are used in the next wizard step.
I have the grid view with boundfield with four columns. I created the text box when gridview row created event. I need to filter the data the gridview using the textbox and need to know the how to generate event for textbox.
I have gridview that I am filling with records from SQL database. However, I want to populate the gridview with records that match text search criteria. In other words, I want to be able to key in a word like "network" in a text box, pick up the text, read records and pick up on the records that match that criteria. I am doing fine with building the gridview but I am a bit new to this and I don't know what I do to do text search.
