Forms Data Controls :: Capturing Check Box Selection In Dynamic Gridview
Mar 7, 2011
I have a grid view with the following structure
[Code]....
Here is the scenario:
The data is populated in the gridview dynamically at runtime The number of rows vary each time The auto postback event has been set to true I need to capture the rows that are selected, When I try to capture the button click event; the gridview is null(I understand that it has to be rebound on each postback). Hence this is not working
[Code]....
I also tried this, the rowcommand event; It is also not getting generated. The gridview rowcommand is not getting fired
[Code]....
I need the rows which are selected using the checkbox in the above mentioned sceanrio.
when we select a check boxes creat dynamic check boxes. I have a main catagory check box when we select this main catagory check box creat subcatagory check boxes related to main catagory dynamically.
I've created a number of identical controls in a varying number depending on how many employees are under a supervisor. What I am trying to do now is to see which set of controls are checked via a checkbox and return a value from the label field in that particular set. Here is my code:
[Code]....
What I am trying to grab in particualr is the PayRoll Label. I've named sequentially as "lblPayRoll" + the counter. Which from what I think I should be able to do is get the total count of my array and from then loop through the controls and grab the label data.
Problem is that I can get the data, but it disappears after I click the button to grab it. I think I am saving everything to the viewstate, but they just disappear.
I have two pages, the first one displays a list of products in a gridview, one column in the gridview is a hyperlink, this can be clicked on to get further details about the product. Each row in the gridview can be selected, certain details are added to an array (including the hyperlink column). I them want to display these details on page number two. All details are displayed except the hyperlink field.Has anybody any ideas as to what I'm doing wrong? The code is as follows:
My Problam is on Capturing Text Box and Dropdown seleted itam from grid view i create a gridview with Empty DB binding using [URL] this senirio. I only used setinitional value() function and called its in page load as discribed in above lonk. insted of adding New record Button i callled a java scrit code discribed below. and i also create a button (SAVE) to capture a value intered in text box . On this button click event i try to capture a textbox and dropdown value like
for (int i = 0; i < Gridview1.Rows.Count; i++) { DropDownList sen_to1 = (DropDownList)Gridview1.Rows[i].Cells[1].FindControl("DD_sento_org"); TextBox Add_to1 = (TextBox)Gridview1.Rows[i].Cells[2].FindControl("Txt_addto"); int Add_to = Convert.ToInt32(sen_to1.SelectedValue); String Addd_to = Add_to1.Text; }
but its not working i can not go inside loop.
<script type='text/javascript' language='javascript'> function AddNewRecord(keyCode, obj) { if (window.event.keyCode==13 )var grd = document.getElementById('Gridview1'); var tbod=grd.rows[0].parentNode; var newRow=grd.rows[grd.rows.length - 1].cloneNode(true); cleanUpInputs(newRow); tbod.appendChild(newRow); } } return false ;
i have a UP and DOWN buttons ouside a gridview and a checkbox inside the templated field .I will check the checkbox to sleect a row , after that if i click on UP button the checkbox above the selected checkbox should be selected.
same with when i click on DOWN button the checkbox below the selected checkbox should be selected.
I have a grid view with two columns...one column has a no. like (123) and a check box....which user can checked or unchecked......all I need to do is that I need to disable the man handling of that check box......rather I would like to see a seperate grid view with the same no. of rows as of the first and in this gridview I may allow to type in or scan the no. and if this scanned or typed number matches any no. in the first gridview number then the corresponding check box should be checked/unchecked.
If there's a better way to accomplish what I'm attempting I haven't found it yet. That being said, I have create a gridview like the one here,[URL]And with some minor tweaking it working great for all my fields, checkboxes, etc. The issue is my last column is another gridview, and I'd like it to function the same. that is, a dynamic gridview inside of a dynamic gridview. I get that I have to create it initially with null values or it won't show up. I guess what I'm having trouble figuring out is instead of go will null data in the parent gridviews column, do I place my blank child gridview. Do I create and bind the child gridview first, or second. Generally just not sure. Also, as far as storing the data from the child gridview goes, will each one need it's own datatable?
I am currently using DevExpress ASPxGridView and want the selection check box to show a redcross image on selection or empty when unselected. Is there any javascript library to do such a thing. If so can you provide me an example.
I currently have a gridview that has 1 column with radiobuttons. I then have a update button to update all the selected records. But what i want to do is add a step before the update. I want to add a multi-line textbox for each radiobutton selected to allow them to add notes/comments for each record before the update occurs.
Because the textbox will be large to allow them to enter the comments, i wanted to list them out seperately per record selected. Maybe a gridview is not what i need for the 2nd part, but thats the scenario and looking for suggestions on what / how to do it.
Example:
GRIDVIEW1
ID column1 column2 column3 radiocolumn 1 1111 2222 3333 Yes / No (selected Yes) 2 2222 3333 4444 Yes / No
I have a parent gridview5 with child gridview 6, today i deployed it to our dev server and on that server we have alot more records, so for the nested gridviews i need to enable paging on the parent gridview5. Doing so works fine, until i make a selection within the child gridview6, once any selection is made, and i try to page the page throws an error, i have the following bound to the parent gridview5.
I am trying to select multiple rows in gridview.But i am stuck at one point now, and not able to proceed.
I my GridView1_RowCreated event i am doing a post back to Gridview selectedindexchanging Event.
[Code]....
In my GridView selected index changing event i am stroing the row index in a List<string> and if user click the same rew twice iam removing the item from list by:
[Code]....
[Code]....
But the problem is the css property does not work correctly, once you click on a row , its sets its property correctly, but if you click second time then it wont clear the css property.
I have requirement as such when user click on a Gridview row then i'll have to pick up the selected values [of row ] highlighting the gridview row into a form beneath the Gridview, later on the form user might or not update the details picked from the gridview . The form even contains a button on it , when the button is clicked i'll have save the changes [ if any made back to the datasource ] and got to progress to the next row automatically and perform the same updations .
I have a small gridview containing two columns: "modeluserid" and "modelid". It fills out nice.
[Code]....
Now, I want that when the user selects a row, he is automatically getting redirected to another page.
For example: (/Evaluationform.aspx?modeluserid=1&userid=1)I've used this code in the c# behind:
[Code]....
The url is generated on each click and the userid variable in the url is correct.
The only problem is that the modeluserid always stays the same for each url? ("1", first value in the table). Does someone know what I am doing wrong with the modeluserid variable?
Is it also possible that the user has to "select" the row instead of an "onclick" on the entire row?
Is it possible to save selected items in a gridview for future purposes?
let say i have a gridview, from all items selected in the gridview I want to give the user the possibilty to save the selected Items,.
in this case the items is data of persons, name adres, email etc. If the data is saved (for instance in a textfile) it should be reusable the next time. so a user can choose again a selection frmo the gridview or can load the earlier saved list.
I have a gridview bound to a dataset and I do not want to display the id column or the select hyperlink. How can I have a user click anywhere in a row and have the application behave as if they clicked the standard select hyperlink. the one or two approaches I have seen on blogs have not been successful for me. maybe I was missing a piece
I have a gridview that displays the data of my database. What i want is a detailsview that gives me the details of the record i select in the gridview. Both the gridview and the detailsview are on one page. I use objectdatasources to get the data from the database. In the ObjectDataSource i select the gridview-control to get the selected value. But i get the following error: An object of type System.String can not be converted to DataTable. I also tried the following:
leaving the ODS control to none and passing the value via the protected sub ObjectDataSourceDetails_Selecting: e.inputparameter("id") = gridview1.SelectedValue
The problem is this: when i click on select in the gridview, the data won't display any data in the detailsview.How could i solve this?
I have 3 gridviews on a page in a parent child relationship. i.e, when Grid1 is selected, any child rows will be shown in grid2. When a row is selected on grid 2 , any child rows will be shown in grid 3.
I have a single formview used for editing and inserting tied to all the 3 gridviews as they are of the same table structure.
The issue is whenever an insert or update happens on the formview, all the selection is lost. How do I retain the selection on the appropriate gridviews and also refresh only the gridview which caused the change?
For eg) when I select a row in grid 1, the child row shows up in Grid 2 . When I selected the row in Grid 2 for edit, the data appears in the formview. After I update the data in formview, when the page gets refreshed, the row in Grid2 does not remain selected. How do I retain the selection?
I am creating a form that has several fields at the top such as date range, area, etc, the user can change and click a submit button to view all the rows that match in a gridview below these fields. I need to know how to change the "Where" condition based on the user input on the datasource bound to the gridview.
I've been strugglying with this for some time now and I cannot seem to find what I'm doing wrong. I have a gridview with a hyperlink field, so when the user clicks on the hyperlink it takes them to the next page but I want to store 2 field value's in session. I've tried it the url way but I get a "Input string was not in a correct format"
and for security reasons I dont think its the best way, the only other way is for it to be stored in session.
I'm trying to filter data based on the selected value from a drop down list and the according values of a local variable within a gridview_rowdatabound event. For example, if "In Arrears" is selected, the gridview should return all rows where the account balance is less than -100. So far, when I select a value from the dropdown list, it has no effect on the gridview. Here's the code I have:
If (DropDownList1.SelectedIndex = 0) Then e.Row.Visible = True ElseIf ((DropDownList1.SelectedIndex = 1) And (AccountBalance <= -100)) Then e.Row.Visible = False ElseIf ((DropDownList1.SelectedIndex = 2) And (AccountBalance > 100) And (AccountBalance < -100)) Then e.Row.Visible = False End If
I have a gridview which i was trying to set the row that was currently selected to a different color.. i have used the SelectedRowStyle and works fine, but my needs are to highlight the row regardless of what button or link was clicked on within the row.. thats my description of "selected" i know that that the styles are based on events.. but i dont care if you click on edit, select, delete or any other button within the row.. i want to highlight the row so you know what record you are working with.. if i add the EditRowStyle, then if i selected row 5 it highlights.. no biggy, but with the edit row style, if i then click edit on row 2, then i have 2 records highlighted.. Is there not any way to determine if anything was done within a row and highlight it?
I have Edit / Delete / Select buttons enabled on my gridview.. Originally i had added the code to change the BackColor when you made a selection.
But now as the edit and delete functions are being completed.. i need to enable that coloring regardless which linkbutton you select.. As long as something on that row is selected, then i need to change it.
I have a formview tied to a gridview. The formview shows the data for the row selected in the gridview. The formview is invisible by default , default mode is readonly and becomes visible only on Selecting a row in the gridview. I make it visible in the SelectedIndexchanged event of the gridview. There are Insert and update buttons present outside the formview which perform the insert and update manually using code-behind.
After an insert or update on the formview, how do I retain the gridview selection?
